From the development of foreign communication satellites, most of newly transmitted communication satellite systems carry one or more phased array antennas, the flexible scheduling capability of beams is improved, and the capacity of beam scheduling and the forming capability of a reflector antenna are mutually complemented. With the increasing working frequency of the satellite, the millimeter wave frequency band is widely used in the communication satellite due to its characteristics of high bandwidth, small size, light weight and better anti-interference.
