摘　　要：针对深空探测大型天线多频段工作需要用频率选择面（FSS）进行分频或实现收发双工的需求，设计了1种十字孔金属格栅频率选择面，它具有反射s频段能量、传输x频段能量的能力。用高频结构仿真软件进行仿真优化，并与试验结构进行了比较，仿真结果与实验数据具有良好的一致性，证明了设计优化方法的正确性。For the demands for frequency demultiplicating, transmitting and receiving using frequency selected surface in the multiple frequency operation of large deep space detection antenna, the design of frequency selected surface with cross holed metal grids is presented in the paper. It has the function of reflecting S band and transmitting X band simultaneously. The simulation optimization has been conducted by simulation software of high frequency structure. The comparison between the optimization and experiment results has been conducted. The simulation results are corresponding with the experiments results, which shows the validity of the proposed optimization method.
