Dual-frequency cross-polarized dipole antenna

This creation relates to a dual-frequency cross-polarized dipole antenna, especially one that can effectively enhance the electric field coverage of the overall antenna, and has the effect of omnidirectional coating, while further improving the field effect gain of the overall antenna, thereby eliminating the general The electric field radiation of the antenna covers dead angles and mutual interference.

According to the structure and application of the general dipole antenna (refer to FIG. 1), the column antenna 1 is correspondingly disposed on the side of the board body 1 and the board body 1 is vertically arranged. In order to improve the signal transmission performance of the antenna conductor 11, under actual conditions, when the antenna conductor 11 is transmitted by the signal, it is often affected by the law of electromagnetic wave radiation, resulting in the polarization direction of the electric field 2 of the antenna conductor 11. The vertical mode (ie, the Y-axis direction) radiates outward, thereby causing the two ends of the antenna conductor 11 not to be covered by the electric field 2 of the antenna, so that the two ends of the plate body 1 are radiated to a dead angle, so that the field effect gain of the antenna is lowered. At the same time, the antenna conductor 11 is only composed of a corresponding columnar body, and the transmission process is performed by transmitting and receiving a single signal bandwidth, thereby facilitating the situation that the signal transmission and reception bandwidth is insufficient; How to eliminate the above-mentioned defects and provide a situation that can increase the coverage of the electric field and the bandwidth of the signal transmission and reception, and the lack of radiation dead angle and insufficient bandwidth, which is what the creator of the case wants to solve. The point where the operation is difficult, so this one kind of developing cross-polarization dual-band dipole antenna.

The main purpose of the present invention is to provide a dual-frequency cross-polarized dipole antenna comprising: a substrate; a horizontally polarized first antenna portion disposed on one side of the substrate, the sub-set There is a corresponding signal transmitting and receiving area, and the signal transmitting and receiving area has a high frequency signal transmitting and receiving unit at one end thereof, and a low frequency signal transmitting and receiving unit at the other end; and a vertically polarized second antenna portion is disposed at the signal transmitting and receiving area. The other side end of the substrate is provided with a corresponding signal transmitting and receiving area, and the signal transmitting and receiving area is provided with two high-frequency signal transmitting and receiving units and a low-frequency signal transmitting and receiving unit extending in parallel; When the electric field of the antenna portion and the second antenna portion are simultaneously radiated, the electric field of the first antenna portion can be radiated in the horizontal direction, and the electric field of the second antenna portion is radiated in the vertical direction, and the electric field radiation of the entire antenna is reduced. Covering the dead angle, effective to effectively enhance the electric field coverage of the overall antenna, and to achieve the full coverage effect, while further improving the field effect gain of the overall antenna, thereby eliminating the electric field radiation of the general antenna. When the dead angle is covered, and the polarization directions of the electric field of the first antenna portion and the second antenna portion are perpendicular to each other, the mutual interference may be reduced; further, as described above, the creation may be Further, a first high-frequency signal transmitting and receiving unit and a low-frequency signal transmitting and receiving unit are disposed through the first antenna portion and the second antenna portion, and the integrated antenna has a plurality of frequency band transmission and reception benefits in a certain area. Generally, the bandwidth of the dipole antenna is insufficient.
