Anti-interference antenna of satellite system

The invention relates to an anti-interference antenna of a satellite system. The anti-interference antenna of the satellite system comprises an antenna array, multiple zero intermediate frequency demodulation devices, a base-band processing device and a zero intermediate frequency modulation device, wherein the antenna array comprises multiple antenna array elements, each antenna array element is connected with one zero intermediate frequency demodulation device, each zero intermediate frequency demodulation device is connected with the zero intermediate frequency modulation device through the base-band processing device, satellite communication signals emitted by the satellite communication system are received by the antenna array elements, the satellite communication signals are demodulated by the zero intermediate frequency demodulation devices to acquire base-band demodulation signals, interference inhibition processing on the base-band demodulation signals is carried out by the base-band processing devic
