The beam direction can be switched (pattern reconfigurable) antenna can change the beam coverage of the transmitting and receiving antenna in real time according to the change of the communication environment, so as to effectively avoid noise interference and improve system gain and security. In addition, an antenna with a switchable beam direction generally uses one or a few feeding ports, which can avoid loss in the process of signal synthesis. In order to be able to adjust the radiation state of the antenna according to the coverage area, interference phenomenon, traffic and other conditions of the mobile communication system network, the phase shifter is required to adjust the direction of the radiation pattern transmitted by the base station antenna, so as to meet the flexible adjustment to cover different user areas. requirements.
