ABSTRACT:
In a moving body satellite communication apparatus for performing communication with a satellite by an antenna with a radome mounted on a moving body such as an aircraft, loss due to transmission through the radome, and distortion of polarization characteristics are compensated in the inside of the antenna. Variable phase shifters9aand9band variable attenuators19aand19b, and variable phase shifters10aand10band variable attenuators20aand20bare respectively controlled as one body in each channel, and the whole power EIRP radiated from the antenna is also optimally controlled by a common variable attenuator21inserted independently from the variable attenuators19aand19b, and therefore, radome correction and EIRP control can be simultaneously realized by a relatively simple circuit.
