摘要

介绍了一种用于通信卫星的Ka波段多波束相控阵。天线单元采用双圆极化喇叭结构。采用三角形网格结构构建了发射频率为23ghz、接收频率为26ghz的相控阵。发射部分有320个通道，接收部分有1280个通道。相控阵可同时提供4个发射波束和8个接收波束。扫描角度范围优于13度锥形。等效各向同性辐射功率(EIRP)达到56 dBW, G/T优于19 dB/K。对元件和阵列的性能进行了仿真，为系统设计提供了良好的依据。

Ka band multi-beam phased array antenna for communication satellite application

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.
