摘　　要：文章介绍了反射面天线极化选择栅的设计方法:首先将金属栅条与介质层去耦,二者独立设计;然后,对极化选择栅全模型采用三维电磁场仿真。该方法物理概念清晰,且只需要对最终模型进行三维电磁仿真,计算量小。最后,设计了一个Ku频段的极化选择栅,仿真与测试结果吻合良好,验证了文章方法的有效性。An efficient design method of polarization-selective grids in reflector antennas is presented in this paper. First,metal grids and dielectric supporting structure are designed respectively. Then,the whole model of polarization-selective grids are simulated using three-dimensional electromagnetic tools. The concept of this method is clear and the compute quan-tity is small due to mere once full-wave analysis of the last model. At last,the Ku polarization-selective grid is designed and fabricated. Simulated results agree well with measure data which verifies that this method is valid.
