Problems solved by technology
[0005] In addition, for phased array antennas, since the transceiver components will generate a lot of heat during operation, if the heat cannot be dissipated in time, the temperature of the transceiver components will become higher and higher. Excessive temperature will not only affect the The performance of the transceiver components will also accelerate the aging speed of each device and reduce the life of the system

The invention discloses a circuit board, an antenna assembly and a dual-polarized antenna. The circuit board comprises a first dielectric layer, a feeder line layer and a first metal layer, the feederline layer comprises a horizontal polarization feeder line, a vertical polarization feeder line and a first connecting line, the first connecting line is used for dividing the bottom surface of the first dielectric layer into two relatively independent areas, and the horizontal polarization feeder line and the vertical polarization feeder line are respectively arranged in the two areas; a horizontal polarization coupling gap and a vertical polarization coupling gap are formed in the positions, corresponding to the horizontal polarization feeder line and the vertical polarization feeder line,of the first metal layer respectively, and the first metal layer is connected with the first connecting circuit through the first plated-through hole. The circuit board is matched with the external isolation plate, so that the horizontal polarization feeder line and the vertical polarization feeder line can be isolated, electromagnetic coupling between the horizontal polarization feeder line and the vertical polarization feeder line is eliminated, the isolation degree of the dual-polarization antenna is improved, and the cross polarization component is reduced.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a circuit board, an antenna component and a dual-polarized antenna. Background technique [0002] In modern wireless communication systems, dual-polarized antennas, as a basic radiating unit, are widely used in base station antennas and phased array antennas to improve system performance. [0003] For base station antennas, using polarization diversity technology is a way to reduce multipath loss. Since the dual-polarized antenna realizes the transmission and reception of two mutually orthogonal polarization component signals on one antenna, compared with the implementation of the antenna that uses two antennas to transmit and receive signals, the number of antennas is saved, thereby reducing the antenna Overall volume, reduced weight. [0004] For dual-polarized antennas, in addition to conventional antenna performance indicators, polarization isolation has become an imp...
