1. an array antenna device, it is made up of micro-strip antenna array, reflecting plate and phase shift feeding network, it is characterized in that:

  • described micro-strip antenna array is arranged on above reflecting plate, micro-strip antenna array is provided with four bays, and bay is attached on dielectric substrate by metal radiation sheet and forms;

    Each metal radiation sheet is connected with phase shift feeding network by four feed port, and four bays are individually connected with four phase shift feeding networks respectively;

    Described phase shift feeding network is arranged on the lower section of reflecting plate, two 90 °

    of phase shift power splitters and 180 °

    of phase shift power splitters can be set in phase shift feeding network and connected by microstrip line, phase shift power splitter is provided with input port and output port, phase shift power splitter also sets up and is connected to matched load, by phse conversion between phase shift power splitter, bay can be made to carry out antenna circular polarisation work。
