No. 9,582,051, which claims the priority under 35 U.S.C. §119(a) to Korean Patent Application Serial No. 10-2014-0020467, which was filed in the Korean Intellectual Property Office on Feb. 21, 2014, the entire contentdisclosures of which is herebyare incorporated herein by reference.

TECHNICAL FIELD

0002Various embodiment of the present disclosure relate to a radiant-heat sheet mounted on mobile communication terminal, and more particularly, a mobile communication terminal provided with an antenna.

BACKGROUND

0003In general, a mobile communication terminal is provided with a battery pack within the body thereof to recharge and to use the battery pack. In addition, the mobile communication terminal includes a cover configured to be detachably mounted on the rear side of the body of the mobile communication terminal so that after the cover is removed from the mobile communication terminal, the battery pack mounted in the mobile communication terminal is separated and recharged using a charger. The rear side or cover of the mobile communication terminal is a portion which is directly in contact with a user's hand when the user grips the mobile communication terminal. Thus, the user may feel heat generated from the mobile communication terminal as it is.

0004Meanwhile, as the body of the mobile communication terminal is slimmed and a high specification Application Processor (AP) is used for the mobile communication terminal, a problem of heat generation has been gradually encountered. A main board, on which various electronic components are mounted, is a heat generation source of the mobile communication terminal. In particular, the AP mounted on the main board is the main heat generation source.

0005In addition, it became possible for gradually popularized mobile communication terminals to conduct bidirectional local area communication in a contactless manner using a Near Field Communication (NFC) antenna in the mobile communication terminals. As compared with other types such as existing BLUETOOTH and ZIGBEE, the NFC antenna has advantages in that a communication setting time is short and less malfunctions in recognition although its data transmission speed is slow. As a result, the NFC antenna has been generally employed in mobile communication terminals and applied so that the NFC antenna is being advanced in various fields. Mobile communication terminals with NFC antennas are used as smart cards such as electronic money, electronic wallet, electronic ticketing, door key, and identification card and allow a user to share or exchange, for example, name cards, phone numbers, photographs, or music with an acquaintance.

0006For ensuring smart functions, NFC antennas are mounted on predetermined portions of mobile communication terminals. Considering mountability, the NFC antennas are usually mounted within the mobile communication terminals, or on battery packs or battery covers of the mobile communication terminals.

SUMMARY

0007As the bodies of mobile communication terminals have been slimmed and a high specification Application Processor (AP) has been used for the mobile communication terminal, the problem of heat generation has gradually increased. In addition, upon analyzing a heat generation part of the mobile communication terminal using a thermo-graphic camera, it can be seen that a wide variation in temperature occurs at a boundary between a main board part and a battery pack part. It can be verified that the main board region of the mobile communication terminal generates a lot of heat and the battery pack is relatively cold.

0008Accordingly, it is necessary to transfer the heat toward the battery pack region. However, when an NFC antenna is mounted within a battery pack, it may be difficult to apply, for example, a radiant-heat sheet for transferring the heat to the inside of the battery cover since the performance of the NFC antenna may be degraded. Due to this, the radiant-heat sheet is applied to a region other than the battery region so that there may be a limit in dissipating the heat.

0009Consequently, when the radiant-heat sheet is applied, it is conventionally important to widen the area of the radiant-heat sheet as much as possible in order to dissipate the heat. However, due to the degradation of the performance of the NFC antenna, there may be a difficulty in widening the radiant-heat sheet.

0010To address the above-discussed deficiencies, it is a primary object to secure and apply a radiant-heat sheet as wide as possible so that heat generation of the mobile communication terminal can be reduced without degrading performance of an antenna mounted within a mobile communication terminal or on an attachable/detachable battery pack.

0011In addition, various embodiments of the present disclosure reduce heat generation of a mobile communication terminal by transferring heat from a heat generation part to an area where no antenna is disposed using a radiant-heat connection part.

0012In order to solve the problems described above, there is provided a mobile communication terminal according to an aspect of the present disclosure. The mobile communication terminal includes: a display module; a rear cover; an inner support structure positioned between the display module and the rear cover and including a first surface facing the display module and a second surface facing a side opposite to the display module; a first radiant-heat sheet positioned between the first surface of the support structure and the display module; a printed circuit board positioned between the first radiant-heat sheet and the first surface of the support structure; and a second radiant-heat sheet positioned between the second surface of the support structure and the rear cover.

0013According to another aspect of the present disclosure, there is provided a protective cover of a mobile communication terminal. The protective cover includes: a first cover that covers a first surface of the mobile communication terminal; and a second cover connected with the first cover and configured to be provided on the second surface of the mobile communication terminal to cover a battery accommodation space of the mobile communication battery when the protective cover is assembled on the mobile communication terminal. The second cover includes a radiant-heat sheet that covers an area of one surface of the second cover.

0014According to another aspect of the present disclosure, there is provided a mobile electronic device. The mobile electronic device includes: a display module; an inner support structure; an inner bracket positioned between the display module and the inner support structure and including a first surface facing the display module and a second surface facing an opposite side to the display module; a first radiant-heat sheet positioned between the first surface of the inner bracket and the display module; a printed circuit board positioned between the second surface of the inner bracket and the support structure; and a second radiant-heat sheet positioned between the printed circuit board and the inner support structure.

0015According to still another aspect of the present disclosure, there is provided a mobile communication terminal. The mobile communication terminal includes: a heat generation source disposed inside a terminal body; a battery pack configured to be attachable to and detachable from the terminal body, and disposed at a position spaced apart from the heat generation source; an antenna mounted on a first region of the battery pack; a battery cover configured to be attachable to and detachable from the terminal body; and a radiant-heat part disposed inside the terminal body to be superposed on the heat generation source and not to be superposed on the antenna. The radiant-heat part includes a radiant-heat connection part that transfers heat from the heat generation source toward a region which is not provided with an antenna and is relatively cold compared to the heat generation source.

0016According to yet another aspect of the present disclosure, there is provided a battery cover for a mobile communication terminal including an antenna. The battery cover includes: a radiant-heat part provided on one surface of the battery cover, and disposed not to be superposed on the antenna and a radiant-heat connection part extending from the radiant-heat part. The radiant-heat radiates heat transferred from the mobile communication terminal to a first region which is relatively cold, and the radiant-heat connection part radiates heat transferred from the mobile communication terminal to a second region positioned in a direction which is different from that of the first region.

0017According to yet another aspect of the present disclosure, there is provided a battery pack attachable to and detachable from a mobile communication terminal. The battery pack includes: one surface divided into first and second regions; an antenna provided in the first region; one or more connection antennas extending from the antenna across the second region; and a battery-protective circuit board connected with an end of the connection antenna.

0018As described above, according to the various embodiments of the present disclosure, heat from a heat generation source of a mobile communication terminal is transferred to a relatively low temperature region, for example, a battery pack that is not provided with an antenna, so that the temperature of the heat generation source can be reduced.

0045The mobile communication terminal described below is configured to include an removable (attachable/detachable) battery pack, and a battery cover assembled to be removable from the mobile communication terminal. Hereinafter, configurations of a radiant-heat antenna device, a cover having the same, a battery pack, and a mobile communication terminal according to various embodiments of the present disclosure will be described.

0046<figref idref="DRAWINGS">FIG. 3</figref> is a perspective view illustrating a mobile communication terminal according to an embodiment of the present disclosure in a disassembled state in which the mobile communication terminal is provided with a radiant-heat sheet. Referring to <figref idref="DRAWINGS">FIG. 3</figref>, the mobile communication terminal (hereinafter, referred to as a “terminal”) according to the present embodiment includes a display module <b>1000</b> disposed on the front side of the terminal, and a rear cover <b>1100</b> disposed on the rear side of the terminal, and also includes a Printed Circuit Board (PCB) on which various electronic components are mounted, an inner support structure <b>1200</b>, and one or more radiant-heat sheets <b>1400</b> and <b>1500</b> between the display module <b>1000</b> and the rear cover <b>1100</b>.

0047The inner support structure <b>1200</b> includes a first surface <b>1220</b> facing the display module <b>1000</b> and a second surface <b>1210</b> facing the side opposite to, namely facing away from, the display module <b>1000</b>. The first surface <b>1220</b> is the rear side of the inner support structure, and the second surface <b>1210</b> is the front side of the inner support structure. The inner support structure <b>1200</b> is a kind of a rear case that can be a basic frame that supports various mounted electronic components. The inner support structure <b>1200</b> includes one or more metal patterns <b>1513</b> and <b>1610</b>, and a space that accommodates a component including at least one metal pattern. The at least one metal pattern included within the inner support structure <b>1200</b> can be configured in an antenna pattern and the component can be a battery pack <b>1600</b>. The metal pattern can be provided on the battery pack <b>1600</b>, and the battery pack <b>1600</b> includes the metal pattern <b>1610</b> on one side thereof. The metal pattern <b>1610</b> can be an NFC antenna.

0048The inner support structure <b>1200</b> further includes an inner bracket <b>1300</b> that supports the PCB and various electronic components. The PCB can be disposed between the inner support structure <b>1200</b> and the inner bracket <b>1300</b>. The inner support structure <b>1200</b>, the PCB, and the inner bracket <b>1300</b> are assembled in a vertically stacked structure and can support various electronic components. The inner support structure <b>1200</b>, the inner bracket <b>1300</b>, and the PCB include openings <b>1215</b>, <b>1310</b> and <b>1315</b>, respectively, to locate the battery pack <b>1600</b> therein.

0049The one or more radiant-heat sheets include first and second radiant-heat sheets <b>1400</b> and <b>1500</b>. The first radiant-heat sheet <b>1400</b> is disposed between the display module <b>1000</b> and the first surface <b>1220</b> of the inner support structure and can be configured in a shape to transfer the heat transferred from a heat generation source to a relatively cold region. For example, an AP or an LED disposed on the PCB may be considered a heat generation source in the terminal, and in particular, the AP may be considered the hottest heat generation source.

0050In addition, at least a part of the second radiant-heat sheet <b>1500</b> can be positioned between the second surface <b>1210</b> of the inner support structure and the rear cover <b>1100</b>. The second radiant-heat sheet <b>1500</b> is attached to or housed in the rear cover <b>1100</b>, in which the second radiant-heat sheet <b>1500</b> is disposed to not be superposed on the metal pattern <b>1610</b>. The second radiant-heat sheet <b>1500</b> includes a first portion <b>1510</b> at a position corresponding to the heat generation body, in which the first portion <b>1510</b> extends from the second radiant-heat sheet at least not to be superposed on the position corresponding to the metal pattern <b>1610</b>. The extending second portion <b>1520</b> transfers the heat transferred from heat generation body to a component, for example, one side of the battery pack <b>1600</b> where the metal pattern <b>1610</b> is not provided.

0051At least one of the first radiant-heat sheet <b>1400</b> and the second radiant-heat sheet <b>1500</b> includes one or more of natural graphite particles, compressed particles of exfoliated graphite, artificial graphite particles, copper, graphene particles, carbon nanotubes (CNT), and graphene hybrid.

0052In the following description of the mobile communication terminal including the radiant-heat sheets according to various embodiments of the present disclosure, the mobile communication terminal will be described in comparison to a second mobile communication terminal including a radiant-heat sheet for the convenience of description.

0053<figref idref="DRAWINGS">FIG. 18</figref> is a table representing temperature distributions of the mobile communication terminals to which radiant-heat sheets are attached according to various embodiments. <figref idref="DRAWINGS">FIG. 18</figref> is a test table representing temperatures and temperature distributions after heat generation sources, such as APS, are disposed on left regions of the mobile communication terminal (see <figref idref="DRAWINGS">FIG. 3a</figref>), and radiant-heat sheets of various shapes are attached to the inner surfaces of the battery covers removably assembled on the mobile communication terminals.

0054It can be seen that the temperature of the heat generation source is the highest (52.1° C.) when no radiant-heat sheet is attached to the battery cover (No sheet). In addition, it can be seen that in the case where radiant-heat sheets are attached to the battery covers (Case #1 to Case #4), the temperature of the heat generation part (rear side temperature) is the lowest (47.8° C.) when the heat of the heat generation source is transferred to the battery pack using the radiant-heat connection part (Case #3).

0055Hereinafter, descriptions will be made on the mobile communication terminal radiating heat according to various embodiment of the present disclosure with reference to <figref idref="DRAWINGS">FIG. 18</figref> as well.

0056<figref idref="DRAWINGS">FIGS. 4A and 4B</figref> are a front view and a rear view of a mobile communication terminal (hereinafter, referred to as “terminal”) having a near field wireless communication antenna mounted therein according to the prior art, wherein <figref idref="DRAWINGS">FIG. 4A</figref> illustrates a mobile communication terminal in a state where a battery cover is removed and a battery pack is mounted and <figref idref="DRAWINGS">FIG. 4B</figref> illustrates an inner surface of the removed battery cover. <figref idref="DRAWINGS">FIG. 5</figref> is a cross-sectional view of a mobile communication terminal having a near field wireless communication antenna mounted therein according to the prior art

0057As illustrated in <figref idref="DRAWINGS">FIGS. 4A and 4B</figref> and <figref idref="DRAWINGS">FIG. 5</figref>, when the mobile communication terminal <b>30</b> is configured such that a battery pack <b>31</b> is removable, a battery cover <b>32</b>, which is attachable to and detachable from the rear side of the body of the terminal, can be configured. For the convenience of description, an attachment/detachment structure of the battery cover <b>32</b> is omitted. Although not illustrated, the above-mentioned attachment/detachment structure of the battery cover <b>32</b> is configured by a combination of a plurality of protrusions and a plurality of recesses.

0058As illustrated in <figref idref="DRAWINGS">FIG. 4A</figref>, when the battery cover <b>32</b> is removed from the terminal <b>30</b>, the mounted state of the battery pack <b>31</b> is shown. The battery pack <b>31</b> is seated in a battery slot provided on an inner surface <b>300</b> of the terminal and electrically connected to a battery connector <b>36</b> to supply electric power. On a left region of the battery pack <b>31</b>, a heat generation source <b>34</b>, such as an AP mounted on a main board (not illustrated) (mounted inside the rear side of the terminal to be stacked) is positioned, and on a region above the battery pack <b>31</b>, a camera c, an LED provided in a flash f, and a socket s are positioned. An example of the heat generation source <b>34</b> can be, for example, the AP <b>34</b>, the LED f, or the camera c element, but the AP <b>34</b> can be considered the hottest heat generation source within the terminal. Accordingly, the place where the AP <b>34</b> exists may be considered a hot spot that is the hottest region in the terminal <b>30</b>.

0059Specifically, with reference to the center of the terminal <b>30</b>, the heat generation source <b>34</b> is positioned substantially in the left region, the battery pack <b>31</b> is positioned in the right region to be spaced apart from the heat generation source <b>34</b>, and the camera c, the LED of the flash f and the socket s are positioned in the upper region. The heat generation source <b>34</b> is positioned in the left region of the terminal <b>30</b> at a position adjacent to the battery connector <b>36</b>. Since the heat generation source <b>34</b> should be positioned in the left region to be adjacent to the camera c, the flash f and the battery connector <b>36</b> in order to facilitate interlock there between and power supply, the heat generation part <b>34</b> is disposed on the main board preferably at a position adjacent to the battery connector <b>36</b>. In addition, the camera c, the flash f, and the card socket s are preferably disposed not to be far from the heat generation source <b>34</b>.

0060The antenna <b>33</b> and the radiant-heat part <b>35</b> can be configured to provide the antenna function to the terminal. When the antenna <b>33</b> is an NFC antenna, the NFC antenna <b>33</b> can be provided at a predetermined position on the top surface <b>310</b> of the battery pack <b>31</b>. When the NFC antenna <b>33</b> is provided on the battery pack <b>31</b>, the NFC antenna <b>33</b> can be disposed at a place adjacent to the heat generation part <b>34</b>. That is, when the battery pack <b>31</b> is roughly divided into an upper region and a lower region, the NFC antenna <b>33</b> can be mounted on the upper region of the battery pack <b>31</b>.

0061A radiant-heat part <b>35</b> is mounted on an inner surface <b>320</b> of the battery cover <b>32</b>, which is a surface facing the inner surface <b>300</b> of the terminal <b>30</b> when the battery cover <b>32</b> is assembled with the terminal, so as to reduce the temperature of the heat generation part <b>34</b>. When the battery cover <b>32</b> is assembled on face the inner surface <b>300</b> of the terminal <b>30</b>, the radiant-heat part <b>35</b> is disposed to be superposed on the heat generation source <b>34</b> so that heat is radiated in a direction away from the heat generation source <b>34</b> by the radiant-heat part <b>35</b>. Thus, the temperature of the heat generation source <b>34</b> can be reduced, and the temperature of the terminal can be entirely reduced. Meanwhile, since the radiant-heat part <b>35</b> includes a metallic material, which is excellent in heat conductivity, for example, copper (Cu), the radiant-heat part <b>35</b> is disposed to not be superposed on the antenna <b>33</b>.

0062When the radiant-heat part <b>35</b> is disposed to be superposed on the antenna <b>33</b>, the performance of the antenna <b>33</b> may deteriorate. When the temperature of the heat generation source <b>34</b>, for example, the AP, increases, the main function of the terminal may deteriorate so that the performance of the terminal may be degraded. Further reduction of the temperature of the heat generation source <b>34</b> is required. As the terminal <b>30</b> is further improved in specification in the future, the heat generation problem of the AP will become further evident and the performance of the mobile communication terminal may be affected. In <figref idref="DRAWINGS">FIG. 4B</figref>, reference numeral “<b>321</b>” denotes a camera opening, reference numeral “<b>322</b>” denotes a flash opening, and reference numeral “g” denotes a battery attachment/detachment recess.

0063Hereinafter, configurations of an antenna, a battery pack having the same, and a mobile communication terminal according to various embodiment of the present disclosure will be described with reference to the accompanying drawings.

0064<figref idref="DRAWINGS">FIGS. 6A and 6B</figref> are a front view and a plan view of a mobile communication terminal having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure, wherein <figref idref="DRAWINGS">FIG. 6A</figref> illustrates a mobile communication terminal in a state where a battery cover is removed and a battery pack is mounted and <figref idref="DRAWINGS">FIG. 6B</figref> illustrates an inner surface of the removed battery cover. <figref idref="DRAWINGS">FIG. 7</figref> is a cross-sectional view schematically illustrating a mobile communication terminal having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure.

0065As illustrated in <figref idref="DRAWINGS">FIGS. 6B and 6A</figref> and <figref idref="DRAWINGS">FIG. 7</figref>, the battery pack <b>41</b> is seated in a battery slot provided on an inner surface <b>400</b> of the terminal <b>40</b> and electrically connected to a battery connector <b>46</b> to supply electric power. In a left region of the battery pack <b>41</b>, a heat generation source <b>44</b>, such as an AP, mounted on a main board B (illustrated in <figref idref="DRAWINGS">FIG. 7</figref>) is positioned, and in a region above the battery pack <b>41</b>, a camera c, an LED provided in a flash f, and a socket s are positioned. The heat generation source <b>44</b> can be, for example, the AP, the LED, or the camera c element, but the AP can be considered the relatively hottest heat generation source within the terminal. Accordingly, the place where the AP exists can be considered a hot spot that is the hottest region in the terminal.

0066With reference to the center of the terminal body <b>40</b>, the heat generation source <b>44</b> is positioned substantially in the left region, the battery pack <b>41</b> is positioned in the right region to be spaced apart from the heat generation source <b>44</b>, and the camera c, the LED and the card socket are positioned in the upper region. The heat generation source <b>44</b> is positioned in the left region of the terminal body <b>40</b> at a position adjacent to the battery connector <b>46</b>. Since the heat generation source <b>44</b> should be positioned in the left region to be adjacent to the camera c, the flash f and the battery connector <b>46</b> in order to facilitate interlock there between and power supply, it is preferable that the heat generation source <b>44</b> is disposed at a location adjacent to electronic components which consume a lot of power, if possible.

0067In addition, the antenna <b>43</b> and the radiant-heat part <b>45</b> is configured to provide an antenna function to the mobile communication terminal <b>40</b>. The antenna <b>43</b> mounted on the mobile communication terminal <b>40</b> can be a thin and flexible NFC antenna or a wireless charging antenna. When the antenna <b>43</b> is the NFC antenna, the NFC antenna may be or may not be provided on the top surface of the battery pack <b>41</b>. When the NFC antenna <b>43</b> is not provided on the battery pack <b>41</b>, the NFC antenna <b>43</b> can be provided on a predetermined region of the rear side <b>400</b> of the terminal body <b>40</b>.

0068According to an embodiment, when the NFC antenna <b>43</b> is provided on the battery pack <b>41</b>, the NFC antenna <b>43</b> is disposed at a location that is far from the heat generation part <b>44</b>. That is, when the battery pack <b>41</b> is roughly divided into a first region (lower region), and a second region (upper region <b>410</b>), the NFC antenna <b>43</b> is disposed in the lower region of the battery pack <b>41</b>. The first region is positioned a relatively long distance from the heat generation source <b>44</b> compared to the second region, and the second region is positioned a relatively short distance from the heat generation source <b>44</b> compared to the first region. The antenna <b>43</b> is disposed in a protrusion of the first region and further includes a connection antenna <b>430</b> to be connected with the battery connector <b>46</b>.

0069As illustrated in <figref idref="DRAWINGS">FIG. 6B</figref>, a radiant-heat part <b>45</b> is attached to the inner surface of the battery cover <b>42</b> so as to reduce the temperature of the heat generation part <b>44</b>. When the battery cover <b>42</b> is assembled on the terminal body <b>40</b>, the radiant-heat part <b>45</b> is disposed to be superposed on the heat generation source <b>44</b> so that heat is radiated in a direction far away from the heat generation source <b>44</b> by the radiant-heat part <b>45</b>. Thus, the temperature of the heat generation source <b>44</b> can be reduced and the temperature of the terminal body <b>40</b> can be entirely reduced. Since the radiant-heat part <b>45</b> includes a metallic material that is excellent in heat conductivity, for example, copper, the radiant-heat part includes a radiant-heat connection part <b>450</b> which is disposed not to be superposed on the antenna <b>43</b> and transfers heat to a region which is relatively cold as compared to the heat generation source <b>44</b>. An example of the cold region can be a region <b>420</b> that is not superposed on the connection antenna <b>430</b> in the second region of the battery pack <b>41</b>. That is, the radiant-heat connection part <b>450</b> absorbs heat transferred from the heat generation source <b>44</b> and radiates the heat to the region <b>420</b> of the battery pack, which is relatively cold. The radiant-heat connection part <b>450</b> can be configured in a sheet shape using a material that is the same as that of the radiant-heat part <b>45</b>. The radiant-heat part <b>45</b> and the radiant-heat connection part <b>450</b> include one or more of natural graphite particles, compressed particles of exfoliated graphite, artificial graphite particles, copper, graphene particles, CNT, and a graphene hybrid. The radiant-heat part and the radiant-heat connection part to be described later can include the above-mentioned materials.

0070As described below, the radiant-heat connection part <b>450</b> provides an effect of reducing the temperature of the heat generation source <b>44</b>. As can be seen from <figref idref="DRAWINGS">FIG. 18</figref>, the temperature of the rear surface of the heat generation source is reduced greatest.

0071<figref idref="DRAWINGS">FIG. 8</figref> is a perspective view illustrating a battery pack having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure. <figref idref="DRAWINGS">FIG. 9</figref> is a perspective view illustrating a battery pack having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure in a state where a protective cap is removed. The configuration of the battery pack according to the embodiment of the present disclosure will be described with reference to <figref idref="DRAWINGS">FIGS. 8 and 9</figref>.

0072As already described, one side of the battery pack <b>41</b> is divided into a first region and a second region. The first region refers to a region where the NFC antenna <b>43</b> is disposed. The first region is the lower region. The second region refers to a battery region where the NFC antenna <b>43</b> is not disposed. The second region is the upper region. The second region includes one or more connection antennas <b>430</b> so as to electrically connect the NFC antenna <b>43</b> to a battery connector. The connection antenna <b>430</b> extends from the antenna <b>43</b> toward a battery-protective circuit board <b>414</b> (see <figref idref="DRAWINGS">FIG. 9</figref>). An end of the connection antenna <b>430</b> is connected to the battery-protective circuit board <b>414</b>, and electrically connected to the battery connector <b>46</b> (see <figref idref="DRAWINGS">FIG. 6</figref>) by the battery-protective circuit board <b>414</b>. The battery-protective circuit board <b>414</b> connected with the connection antenna <b>430</b> is protected by being enclosed by a battery-protective circuit board cap <b>412</b>. The connection antenna <b>430</b> is not superposed on the radiant-heat connection part <b>450</b> so as not to affect degradation of an antenna performance. The connection antenna <b>430</b> can be configured in various shapes and patterns. The connection antenna <b>430</b> illustrated in <figref idref="DRAWINGS">FIG. 8</figref> extends substantially linearly in the longitudinal direction in the periphery of the battery pack <b>43</b> to be electrically connected to the battery-protective circuit board <b>414</b>. Without being limited to the shape, however, the connection antenna <b>430</b> can be configured in various shapes as long as it is connectable to the battery connector. Of course, when the shape of the connection antenna <b>430</b> changes, the shape of the radiant-heat connection part may also change.

0073<figref idref="DRAWINGS">FIGS. 10A and 10B</figref> are front view and a plan view of a mobile communication terminal having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure, wherein <figref idref="DRAWINGS">FIG. 10A</figref> illustrates a mobile communication terminal <b>50</b> in a state in which a battery cover is removed and a battery pack is mounted and <figref idref="DRAWINGS">FIG. 10b</figref> illustrates an inner surface of the removed battery cover <b>52</b>. <figref idref="DRAWINGS">FIG. 11</figref> is a perspective view illustrating a battery pack having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure. In describing a radiant-heat NFC antenna according to an embodiment of the present disclosure with reference to <figref idref="DRAWINGS">FIGS. 10A and 10B</figref> and <figref idref="DRAWINGS">FIG. 11</figref>, descriptions on the redundant components compared to the radiant-heat NFC antenna illustrated in <figref idref="DRAWINGS">FIGS. 8 and 9</figref> will be omitted. Since the radiant-heat NFC antenna illustrated in <figref idref="DRAWINGS">FIGS. 10A and 10B</figref> and <figref idref="DRAWINGS">FIG. 11</figref> has the same configuration as that illustrated in <figref idref="DRAWINGS">FIGS. 8 and 9</figref>, except for the connection antennas <b>530</b> and <b>531</b> and the radiant-heat connection part <b>550</b>, the mobile communication terminal of the present embodiment will be described mainly with the connection antennas and the radiant-heat connection part.

0074The connection antenna extending from the antenna <b>53</b> mounted on the first region (lower region) of the battery pack <b>51</b> extends across the second region <b>510</b> in the horizontal and vertical directions to be connected to the battery connector <b>56</b>. The connection antenna extends along the periphery of the second region <b>510</b> finally toward the battery connector <b>56</b>, in which the connection antenna includes a horizontal connection antenna <b>530</b> and a vertical connection antenna <b>531</b>. The two connection antennas <b>530</b> and <b>531</b> are preferably disposed to extend adjacent to the vertical and horizontal sides of the second region <b>510</b> of the battery pack so as to expand the mounting area of the radiant-heat connection part <b>550</b>. The end of the vertical connection antenna <b>531</b> is connected to the battery-protective circuit board (see <figref idref="DRAWINGS">FIG. 9</figref>) to be electrically connected to the battery connector <b>56</b>.

0075The radiant-heat part <b>55</b> includes a radiant-heat connection part <b>550</b> that is not superposed on the antenna <b>530</b> and the connection antenna <b>531</b> which are mounted in the second region. The radiant-heat connection part <b>550</b> extends from the radiant-heat part <b>55</b> in the vertical direction to transfer the heat transferred from the heat generation source <b>54</b> to a region <b>510</b> where the antenna mounted on the battery pack and the connection antenna are not mounted. That is, the radiant-heat connection part <b>550</b> absorbs the heat from the heat generation source <b>54</b>, and radiates the heat to the region <b>510</b> of the battery pack. The size of the radiant-heat connection part is slightly smaller than the radiant-heat connection part illustrated in <figref idref="DRAWINGS">FIG. 6</figref>. This is due to the connection antenna. Consequently, the radiant-heat connection part <b>550</b> absorbs the heat transferred from the heat generation source <b>54</b> and transfers the heat to the relatively cold region <b>510</b> where the connection antenna is not disposed on the battery pack, thereby lowering the temperature of the heat generation source <b>54</b>.

0076<figref idref="DRAWINGS">FIGS. 12A and 12B</figref> are a front view and a plan view of a mobile communication terminal having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure, wherein <figref idref="DRAWINGS">FIG. 12A</figref> illustrates a mobile communication terminal in a state in which a battery cover is removed and a battery pack is mounted and <figref idref="DRAWINGS">FIG. 12B</figref> illustrates an inner surface of the removed battery cover. <figref idref="DRAWINGS">FIG. 13</figref> is a perspective view illustrating a battery pack having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure. In describing a radiant-heat NFC antenna according to an embodiment of the present disclosure with reference to <figref idref="DRAWINGS">FIGS. 12A and 12B</figref> and <figref idref="DRAWINGS">FIG. 13</figref>, descriptions on the redundant components compared to the radiant-heat NFC antenna illustrated in <figref idref="DRAWINGS">FIGS. 8 and 9</figref> will be omitted. Since the radiant-heat NFC antenna illustrated in <figref idref="DRAWINGS">FIGS. 12A and 12B</figref> and <figref idref="DRAWINGS">FIG. 13</figref> has the same configuration as that illustrated in <figref idref="DRAWINGS">FIGS. 8 and 9</figref>, except for the connection antennas and the radiant-heat connection part, the mobile communication terminal of the present embodiment will be described mainly with the connection antennas and the radiant-heat connection part.

0077The battery pack <b>61</b> includes a top surface <b>611</b>, a bottom surface <b>612</b>, and a plurality of side surfaces <b>613</b> with reference to the state illustrated in <figref idref="DRAWINGS">FIG. 13</figref>. As already described, an NFC antenna <b>63</b> is mounted in the lower region of the top surface of the battery pack <b>611</b>. The NFC antenna <b>63</b> can be provided with a plurality of connection antennas so as to connect the NFC antenna <b>63</b> to a battery connector <b>66</b>. The connection antennas according to the present embodiment include a first connection antenna <b>630</b> disposed on the top surface <b>611</b> of the battery pack, a second connection antenna <b>631</b> disposed on one side surface <b>613</b>, and third connection antennas <b>632</b> and <b>633</b> disposed on the bottom surface <b>612</b>, The first connection antenna <b>630</b> extends from an edge of the NFC antenna on the top surface <b>611</b> of the battery pack. The second connection antenna <b>631</b> extends vertically downwardly along the side surface <b>613</b> from the first connection antenna <b>630</b>. The third connection antennas <b>632</b> and <b>633</b> extend from the second connection antenna <b>631</b> in the vertical and horizontal directions on the bottom surface <b>612</b>, respectively. The horizontal antenna <b>633</b> of the third connection antennas is connected in the battery connector direction. Among the four connection antennas <b>630</b> to <b>633</b>, the end of the third connection antenna <b>633</b> is connected to the battery-protective circuit board (see <figref idref="DRAWINGS">FIG. 9</figref>) to be electrically connected to the battery connector <b>66</b>.

0078The radiant-heat part <b>65</b> includes a radiant-heat connection part <b>650</b> that is not superposed on the antenna <b>63</b> and the first connection antenna <b>630</b>. The radiant-heat connection part <b>650</b> extends in the vertical direction from the radiant-heat part <b>65</b> to transfer heat transferred from the heat generation source <b>64</b> to a region <b>610</b> where the antenna mounted on the battery pack and the connection antenna are not mounted. That is, the radiant-heat connection part <b>650</b> absorbs the heat from the heat generation source <b>64</b> and transfer the heat to the region <b>610</b> of the battery pack. Consequently, the radiant-heat connection part <b>650</b> absorbs the heat transferred from the heat generation source <b>64</b> and transfer the heat to the relatively cold region <b>610</b> where the connection antenna of the battery pack is not disposed, thereby lowering the temperature of the heat generation source <b>64</b>.

0079<figref idref="DRAWINGS">FIGS. 14A and 14B</figref> are a front view and a plan view of a mobile communication terminal having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure, wherein <figref idref="DRAWINGS">FIG. 14A</figref> illustrates a mobile communication terminal in a state in which a battery cover is removed and a battery pack is mounted and <figref idref="DRAWINGS">FIG. 14B</figref> illustrates an inner surface of the removed battery cover. <figref idref="DRAWINGS">FIG. 15</figref> is a perspective view illustrating a battery pack having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure. In describing a radiant-heat NFC antenna according to an embodiment of the present disclosure with reference to <figref idref="DRAWINGS">FIGS. 14A and 14B</figref> and <figref idref="DRAWINGS">FIG. 15</figref>, descriptions on the redundant components compared to the radiant-heat NFC antenna illustrated in <figref idref="DRAWINGS">FIGS. 8 and 9</figref> will be omitted. Since the radiant-heat NFC antenna illustrated in <figref idref="DRAWINGS">FIGS. 14A and 14B</figref> and <figref idref="DRAWINGS">FIG. 15</figref> has the same configuration as that illustrated in <figref idref="DRAWINGS">FIGS. 8 and 9</figref>, except for the connection antennas <b>730</b>, <b>731</b> and <b>732</b> and the radiant-heat connection part <b>750</b>, the mobile communication terminal of the present embodiment will be described mainly with the connection antennas and the radiant-heat connection part.

0080The battery pack <b>71</b> includes a top surface <b>711</b>, a bottom surface <b>712</b>, and a plurality of side surfaces <b>713</b> with reference to the state illustrated in <figref idref="DRAWINGS">FIG. 15</figref>. As already described, an NFC antenna <b>73</b> is mounted in the lower region of the top surface of the battery pack <b>711</b>. The NFC antenna <b>73</b> can be provided with a plurality of connection antennas so as to connect the NFC antenna <b>73</b> to a battery connector <b>76</b>. The connection antenna according to the present embodiment includes a first connection antenna <b>730</b> disposed on the top surface <b>711</b> of the battery pack, a second connection antenna <b>731</b> disposed on one side surface <b>713</b>, and third connection antenna <b>732</b> disposed on the bottom surface <b>712</b>. The first connection antenna <b>730</b> extends from an edge of the NFC antenna on the top surface <b>711</b> of the battery pack. The second connection antenna <b>731</b> extends vertically downwardly along the side surface <b>713</b> from the first connection antenna <b>730</b>. The third connection antenna <b>732</b> extends from the second connection antenna <b>731</b> in the horizontal direction on the bottom surface <b>712</b> toward the battery-protective circuit board. Among the three connection antennas <b>730</b> to <b>732</b>, the end of the third connection antenna <b>730</b> is connected to the battery-protective circuit board (see <figref idref="DRAWINGS">FIG. 9</figref>) to be electrically connected to the battery connector <b>76</b>.

0081The radiant-heat part <b>75</b> includes a radiant-heat connection part <b>750</b> that is not superposed on the antenna <b>73</b> and the first connection antenna <b>730</b>. The radiant-heat connection part <b>750</b> extends in the vertical direction from the radiant-heat part <b>75</b> to transfer heat transferred from the heat generation source <b>74</b> to a region <b>710</b> where the antenna mounted on the battery pack and the connection antenna are not mounted. That is, the radiant-heat connection part <b>750</b> absorbs the heat from the heat generation source <b>74</b> and transfers the heat to the region <b>710</b> of the battery pack. Consequently, the radiant-heat connection part <b>750</b> absorbs the heat transferred from the heat generation source <b>74</b> and transfers the heat to the relatively cold region <b>710</b> where the connection antenna of the battery pack is not disposed, thereby lowering the temperature of the heat generation source <b>74</b>.

0082<figref idref="DRAWINGS">FIGS. 16A and 16B</figref> are a front view and a rear view of a mobile communication terminal having a near field wireless communication antenna mounted therein according to the prior art, wherein <figref idref="DRAWINGS">FIG. 16A</figref> illustrates a mobile communication terminal in a state where a battery cover is removed and a battery pack is mounted and <figref idref="DRAWINGS">FIG. 16B</figref> illustrates an inner surface of the removed battery cover.

0083As illustrated in <figref idref="DRAWINGS">FIG. 16A</figref>, when the battery cover <b>82</b> is removed from the terminal body <b>80</b>, the mounted state of the battery pack <b>81</b> is seen. The battery pack <b>81</b> is seated in a battery slot provided on the inner surface <b>800</b> of the terminal body to be electrically connected to the battery connector <b>86</b>, thereby supplying power. In the region above the battery pack <b>81</b>, a heat generation source <b>84</b> mounted on the main board (not illustrated) (mounted to be stacked in the rear side of the terminal), for example, AP, is positioned, and in the upper region of the battery pack <b>81</b>, a camera c, and an LED provided on a flash f. Although the heat generation source <b>84</b> can be, for example, the AP <b>84</b> or the LED of the flash f, the AP <b>84</b> may be considered the relatively hottest heat generation source within the terminal body. Accordingly, the place where the AP <b>84</b> exists in the terminal <b>80</b> may be considered a hot spot as the hottest region.

0084Specifically, approximately with reference to the center of the terminal body <b>80</b>, the heat generation source <b>84</b> is positioned in the upper region and the battery pack <b>81</b> is positioned in the lower region to be spaced apart from the heat generation source <b>84</b>. The heat generation source <b>84</b> can be positioned at a place adjacent to the battery connector <b>86</b> approximately at the center of the upper region of the terminal body <b>80</b>. The heat generation source <b>84</b> should be positioned adjacent to the camera c, the flash for the battery connector <b>86</b> in the upper region for easy interlocking there between or easy power supply. Thus, the heat generation source <b>84</b> is preferably disposed at a place close to the battery connector <b>86</b> on the main board, if possible. In addition, it is desirable that the camera c and the flash f are also disposed at a place that is not far from the heat generation source <b>84</b>.

0085Meanwhile, the antenna <b>83</b> and the radiant-heat part <b>85</b> can be configured to provide an antenna function to the terminal. When the antenna <b>83</b> is an NFC antenna, the NFC antenna <b>83</b> is provided at a predetermined position on the top surface of the battery pack <b>81</b>. When the NFC antenna <b>83</b> is provided on the battery pack <b>81</b>, the NFC antenna <b>83</b> is mounted at a place adjacent to the heat generation part <b>84</b>. Then, the NFC antenna <b>83</b> can be positioned in the center of the rear side of the terminal <b>80</b>. The NFC antenna <b>83</b> is positioned in the center in consideration of the user's convenience in using the terminal <b>80</b>.

0086A radiant-heat part <b>85</b> can be mounted on an inner surface <b>820</b> of the battery cover <b>82</b> (the surface facing the rear side <b>800</b> of the terminal when the battery cover <b>82</b> is assembled with the terminal) in order to reduce the temperature of the heat generation part <b>84</b>. When the battery cover <b>82</b> is assembled to face the rear side <b>800</b>, the radiant-heat part <b>85</b> is disposed to be superposed on the heat generation source <b>84</b> so that heat is radiated by the radiant-heat part <b>85</b> in a direction far away from the heat generation source <b>84</b>, thereby reducing the temperature of heat generation source <b>84</b>, and hence the temperature of the entire terminal. Meanwhile, since the radiant-heat part <b>85</b> includes a metallic material that is excellent in heat conductivity, for example, copper (Cu), the radiant-heat part <b>85</b> is disposed not to be superposed on the antenna <b>83</b>. When the radiant-heat part <b>85</b> is disposed to be superposed on the antenna <b>83</b>, the performance of the antenna <b>83</b> deteriorates. The heat generation problem of the terminal body <b>80</b> leads to a lot of user discontent and thus it is necessary to further reduce the temperature of the heat generation source <b>84</b>. However, there is a limit in enlarging the area of the radiant-heat part <b>85</b> attached to the battery cover <b>82</b>. As the terminal <b>80</b> is improved to have higher specifications in the future, the heat generation problem of the AP will be further magnified, and may severely affect the performance of the mobile communication terminal.

0087<figref idref="DRAWINGS">FIGS. 17A and 17B</figref> are a front view and a plan view of a mobile communication terminal having a near field wireless communication antenna mounted therein according to various embodiments of the present disclosure, wherein <figref idref="DRAWINGS">FIG. 17A</figref> illustrates a mobile communication terminal in a state where a battery cover is removed and a battery pack is mounted and <figref idref="DRAWINGS">FIG. 17B</figref> illustrates an inner surface of the removed battery cover.

0088As illustrated in <figref idref="DRAWINGS">FIGS. 17A and 17B</figref>, the battery pack <b>91</b> is seated in a battery slot provided on the rear side of the terminal body to be electrically connected to the battery connector <b>96</b>, thereby supplying power to the terminal. In the region above the battery pack <b>91</b>, a heat generation source <b>94</b> mounted on the main board B (see <figref idref="DRAWINGS">FIG. 6</figref>), for example, AP, is positioned, and in the upper region of the battery pack <b>91</b>, a camera c, and an LED provided on a flash f. Although the heat generation source <b>94</b> can be, for example, the AP, the LED, or a camera device, the AP is the relatively hottest heat generation source within the terminal body and may be considered the heat generation source. Accordingly, the place where the AP exists in a mobile communication terminal <b>90</b> may be considered a hot spot in the hottest region.

0089With reference to the center of the terminal body <b>90</b>, the heat generation source <b>94</b> is positioned in the upper region and the battery pack <b>91</b> is positioned in the lower region to be spaced apart from the heat generation source <b>94</b>. In the upper region, for example, the camera c, the LED or a card socket can also be provided. The heat generation source <b>94</b> can be positioned at a place adjacent to the battery connector <b>96</b> in the upper region of the terminal body. The heat generation source <b>94</b> should be positioned adjacent to the camera c, the flash for the battery connector <b>96</b> in the upper region for easy interlocking there between or easy power supply. Thus, the heat generation source <b>94</b> is disposed at a place preferably close to the battery connector <b>96</b> on the main board, if possible.

0090In addition, the antenna <b>93</b> and the radiant-heat part <b>95</b> can be configured to provide an antenna function to the mobile communication terminal <b>90</b>. When the antenna <b>93</b> mounted on the mobile communication terminal <b>90</b> can be an NFC antenna that is thin and is made of a soft material, or a wirelessly charged antenna. When the antenna <b>93</b> is the NFC antenna, the NFC antenna may be or may not be provided on the top surface of the battery pack <b>91</b>. When the NFC antenna <b>93</b> is not provided on the battery pack <b>91</b>, the NFC antenna <b>93</b> can be provided in a predetermined region of the rear side <b>900</b> of the terminal body <b>90</b>.

0091According to the present embodiment, when the NFC antenna <b>93</b> is provided on the battery pack <b>91</b>, the NFC antenna <b>93</b> can be disposed at a place which is far from the heat generation source <b>94</b>. That is, when the mounting area of the battery pack <b>91</b> is roughly divided into a first region and a second region, the NFC antenna <b>93</b> is disposed in the first region. The first region can be positioned a relatively long distance from the heat generation source <b>94</b> compared to the second region, and the second region can be positioned a relatively short distance from the heat generation source <b>94</b> compared to the first region. The antenna <b>93</b> is disposed in the first region and further includes a connection antenna <b>930</b> to be connected to the battery connector <b>96</b>.

0092As illustrated in <figref idref="DRAWINGS">FIG. 17b</figref>, a radiant-heat part <b>95</b> can be mounted on an inner surface of the battery cover <b>920</b> in order to reduce the temperature of the heat generation part <b>94</b>. When the battery cover <b>92</b> is assembled on the terminal body <b>90</b>, the radiant-heat part <b>95</b> is disposed to be superposed on the heat generation source <b>94</b> so that heat is radiated by the radiant-heat part <b>95</b> in a direction far away from the heat generation source <b>94</b>, thereby reducing the temperature of heat generation source <b>94</b>, and hence the temperature of the entire terminal body <b>90</b>. Meanwhile, since the radiant-heat part <b>95</b> includes a metallic material that is excellent in heat conductivity, for example, copper (Cu), the radiant-heat part <b>95</b> is disposed not to be superposed on the antenna <b>93</b> and includes a radiant-heat connection part <b>950</b> that transfers the heat to a relatively cold region compared to the heat generation source <b>94</b>. An example of the cold region can be the region <b>910</b> where the battery pack <b>91</b> is not superimposed with the connection antenna <b>950</b>. That is, the radiant-heat connection part <b>950</b> absorbs the heat transferred from the heat generation source <b>94</b> and radiates the heat to the relatively cold region <b>910</b> of the battery pack. The radiant-heat connection part <b>950</b> is formed in a sheet shape using the same material as the radiant-heat part <b>95</b>. The radiant-heat part <b>95</b> and the radiant-heat connection part <b>950</b> include a graphite material. The temperature of the heat generation source <b>94</b> is further reduced by the radiant-heat connection part <b>950</b>.
