【摘要】设计了一套S频段圆极化相控阵天线，该相控阵天线采用9个微带贴片天线单元进行优化排列与旋转组阵实现。通过HFSS软件仿真，在辐射功率10 dBW的情况下，该相控阵天线在方位360o俯仰±80o的大扫描角范围内，具有大于15 dBW的等效全向辐射功率（EIRP），法向轴比在整个频带内平坦且小于0.5 dB。设计并装配好该相控阵天线后进行测试，得到扫描范围内大于15 dBW的EIRP值，同时测得法向轴比在整个频带内平坦且小于1 dB，测试值与仿真设计值吻合很好。%An S band circularly polarized phased-array antenna was designed, which was realized by arranging and properly rotating 9 microstrip-patch antenna units. Through simulation by HFSS software, in case of 10 dBW radiation power, the phased-array antenna’s EIRP can be larger than 15 dBW in any azimuth of 360o with the large scanning angle of ±80o. Meanwhile, the simulated axial ratio of normal direction is flat in the working band and lower than 0.5 dB. The antenna was assembled and measured. Results show that EIRP is larger than 15 dBW in all the scanning range. Meanwhile, the measured axial ratio of normal direction is flat and lower than 1 dB in the working band. All the measured data matches well with the simulation. 【总页数】4页(45-48)
