摘要
This paper presents a Ka band multi-beam phased array for communication satellite. Antenna element is carried out as a double circular polarization horn. Phased array working at 23 GHz of transmitting frequency and 26 GHz of receiving frequency is constructed with triangle grid arrangement. The transmitting part has 320 channels, while the receiving part comprises 1280 channels. The phased array could provide 4 transmitting beams and 8 receiving beams synchronously. Scanning angle range is better than 13 degree of conical. Equivalent isotropic radiated power(EIRP) achieves 56 dBW for each beam, and its G/T is better than 19 dB/K. Performances of the element and array are simulated, which shows good properties for the system design.
