摘　　要：为适应星载高速数据传输需求,提出了一种Ka波段无源相控阵天线系统设计方案。该方案采用了空间馈电无源电扫平面反射阵列天线形式、圆极化微带单元设计以及数字移相模块设计,实现了天线波束的快速扫描,并具有高增益、轻量化和低功耗等优点。实测数据表明:在±15°的波束扫描范围内,天线的最大增益为37.72 dBi。该天线系统为国内首个成功在轨应用的Ka波段无源相控阵天线系统,可以为无源相控阵天线在卫星数据传输中的应用提供参考。A new Ka-band passive phased array antenna system is designed to satisfy the requirements of satellite high-speed data transmission.The scheme adopts the form of a space-fed reflection array,circularly polarized microstrip units,and digital phase shifter modules,which realize the fast scanning of the antenna beam.The antenna system has the advantages of high gain,low power consumption,and low weight.Experimental tests show that the maximum gain of the antenna is 37.72 dBi in the±15°beam scanning range.This antenna system is the first Chinese Ka-band passive phased array antenna system to operate successfully on-orbit.It will provide useful guidelines for the application of passive phased array antennas in the field of satellite data transmission.
