DETAILED DESCRIPTION OF THE INVENTION

0015Certain embodiments of the invention may be found in a method and system for a phased array antenna embedded in and/or on an integrated circuit package. In this regard, a phased array antenna embedded in a multi-layer integrated circuit (IC) package may be utilized for transmitting and/or receiving signals. The multi-layer package may comprise one or more metal layers, insulating material, ferromagnetic, and/or ferrimagnetic materials. In an exemplary embodiment of the invention, the antenna may comprise one or more planar transmission lines. The phased array antenna may comprise a plurality of antenna elements and each antenna element may comprise an interconnection for communicatively coupling to an associated transmitter and/or receiver, a feeder line, a quarter wavelength transformer, and a radiating portion (e.g., a folded dipole). Also in various exemplary embodiments of the invention, an IC enabled to transmit and/or receive signals may be bonded to the multi-layer IC package via one or more solder balls. Accordingly, the IC may communicate a reference signal and/or one or more phase shifted versions of said reference signal to the antenna. In an exemplary embodiment of the invention, one or more phase shifters (fabricated, for example, in planar transmission line) may be embedded in the multi-layer IC package and may be controlled via logic, circuitry, and/or code within an IC bonded to the multi-layer IC package.

0016<figref idref="DRAWINGS">FIG. 1A</figref> is diagram illustrating a configurable antenna embedded in and/or on an integrated circuit package, in accordance with an embodiment of the invention. Referring to <figref idref="DRAWINGS">FIG. 1</figref>, there is shown an multi-layer Integrated circuit (IC) package <b>102</b>, an associated IC (“chip”) <b>106</b>, a phased array antenna <b>102</b>, and solder balls <b>108</b>.

0017The IC <b>106</b> may comprise suitable logic, circuitry, and/or code for performing one or more functions associated with transmitting and/or receiving RF signals. In this regard, the IC <b>106</b> may comprise all or a portion of the system <b>420</b> described with respect to <figref idref="DRAWINGS">FIG. 4</figref>. In this regard, the IC <b>106</b> may utilize a phased array antenna embedded in the package <b>104</b> for transmitting and/or receiving RF signals. In this regard, the IC <b>106</b> may comprise suitable logic, circuitry and/or code for driving the antenna <b>102</b> with a plurality of phase shifted signals. For example, the IC <b>106</b> may comprise a transmitter and/or a receiver. Alternatively, the IC <b>106</b> may comprise phase shifting circuitry and may be coupled to a separate transmitter and/or receiver (e.g., via one or more traces on a PCB). In still another embodiment, phase shifting elements may be fabricated in the package <b>104</b> and the package <b>104</b> may be utilized as a “stand alone” or “standardized” antenna which may be communicatively coupled to a variety of transmitters and/or receivers.

0018The IC <b>106</b> may be bump-bonded or flip-chip bonded to the multi-layer IC package <b>104</b> utilizing the solder balls <b>108</b>. In this manner, wire bonds connecting the IC <b>106</b> to the multi-layer IC package <b>104</b> may be eliminated, reducing and/or eliminating uncontrollable stray inductances due to wire bonds. In addition, the thermal conductance out of the IC <b>106</b> may be greatly improved utilizing the solder balls <b>108</b> and the thermal epoxy <b>206</b> (<figref idref="DRAWINGS">FIG. 2</figref>). The thermal epoxy <b>221</b> may be electrically insulating but thermally conductive to allow for thermal energy to be conducted out of the IC <b>106</b> to the much larger thermal mass of the multilayer package <b>104</b>.

0019The solder balls <b>108</b> may comprise spherical balls of metal to provide electrical, thermal and physical contact between the IC <b>106</b> and the multi-layer IC package <b>104</b>. In making the contact with the solder balls <b>108</b>, the IC may be pressed with enough force to squash the metal spheres somewhat, and may be performed at an elevated temperature to provide suitable electrical resistance and physical bond strength. The solder balls <b>108</b> may also be utilized to provide electrical, thermal and physical contact between the multi-layer IC package <b>104</b> and a printed circuit board comprising other parts of the wireless system <b>420</b>, described with respect to <figref idref="DRAWINGS">FIG. 4</figref>.

0020The multi-layer IC package <b>104</b> may comprise one or more layers of metal and/or insulating material (various embodiments may also comprise ferromagnetic and/or ferromagnetic areas and/or layers). In this regard, the package <b>104</b> may be fabricated in a manner similar to or the same as an IC. Accordingly, the layers may be utilized to realize circuit elements such as resistors, inductors, capacitors, transmission lines, switches, antennas, etc. In this regard, a plurality of elements of the phased array antenna <b>102</b> may be fabricated in and/or on the package <b>104</b>.

0021The phased array antenna <b>102</b> may comprise a plurality of antenna elements which may each be a metallic and/or conductive structure capable of coupling RF energy to/from, for example, the transceiver <b>423</b> described with respect to <figref idref="DRAWINGS">FIG. 420</figref>. In various embodiments of the invention, each element may be rectangular, circular, and/or another shape. One or more of the elements may be coupled (by way of one or more vias and/or one or more metal layers) to one or more of the solder balls <b>108</b>. In this manner, signals may be conveyed to/from the package <b>104</b>. In the exemplary embodiment depicted, four elements corresponding to four phases are utilized. Accordingly, four phase shifted representations of a reference signal may be transmitted and/or received via the antenna <b>102</b>. Details of the exemplary four element phased array antenna are described below with respect to <figref idref="DRAWINGS">FIG. 1B</figref>.

0022In operation, logic, circuitry, and/or code in the IC <b>106</b> and/or in another device coupled to the package <b>104</b> (e.g., located on a PCB and coupled via one or more of the solder balls <b>108</b>) may transmit and/or receive signals via the phased array antenna <b>102</b>. The phasing of the signals coupled to the antenna elements may be controlled to achieve a desired radiation pattern. In this manner, sensitivity and/or power in a desired direction may be increased over sensitivity and/or power in another direction.
