针对Ka波段卫星通信在收发频段对圆极化切换和圆极化性能的需求，设计了一款用于Ka波段卫星通信的双频段圆极化无源相控阵天线。利用带约束条件的最大功率传输效率法(Method of Maximum Power Transmission Efficiency with Constraints, CMMPTE),通过引入测试接收天线，待设计的天线与之构成无线功率传输(Wireless Power Transmission, WPT)系统，以收发之间传输效率为优化目标函数，同时设置约束条件控制2个正交的场分量，获得发射天线的最优激励分布，在收发频段实现所需偏转方向的左右旋圆极化波束。该天线是一款收发共面的天线，整体尺寸仅为37.18 mm×37.18 mm×0.762 mm,在29.5～30 GHz的发射频段和19.7～20.2 GHz的接收频段内实现了圆极化可重构和波束扫描功能。仿真和实测结果表明，该天线在收发频段分别实现了左右旋波束的切换，圆极化波束在偏转60°时的轴比始终保持在3 dB以下，并且拥有极低的交叉极化电平。
Abstract：In order to meet the requirements of circular polarization switching and circular polarization performance in Ka-band satellite communication, a dual-band circularly-polarized passive phased array antenna is designed for Ka-band satellite communication. By using the Method of Maximum Power Transmission Efficiency with Constraints(CMMPTE) and introducing the test receiving antenna, the antenna array to be designed and the test receiving antenna constitute a Wireless Power Transmission(WPT) system. Taking the transmission efficiency between receiver and transmitter as the optimization objective function, the constraint conditions are set to control two orthogonal field components, and the optimal excitation distribution of the transmitting array antenna is obtained. The left-right circular polarized beam in the desired deflection direction is realized in the transmit-receiving frequency band. The antenna is a transceiver coplanar antenna, its overall size is only 37.18 mm×37.18 mm×0.762 mm, and circular polarization reconfiguration and beam scanning functions are achieved in the 29.5～30 GHz transmission frequency band and 19.7～20.2 GHz receiving frequency band. The results of simulation and measurement show that the antenna can switch the left and right rotating beams respectively in the transmitting and receiving frequency band, and the axial ratio of the circular polarized beam is always below 3 dB when the deflection is 60°, and the cross polarization level is very low.
