摘　　要：在传统十字单元的基础上,文章通过将十字单元中心替换为方环,并在每个十字末端加载一个方环,设计出了一种新型结构的频率选择表面(frequency selective surface,FSS);使用HFSS仿真软件对改进结构和传统结构分别进行建模仿真,将2种结构的角度稳定性和极化稳定性进行了对比,证明了新型单元结构FSS比传统单元FSS具有更好的极化稳定性和角度稳定性;对加工出的实物在垂直入射的情况下进行测试,测试结果与仿真设计吻合较好。On the basis of traditional cross cell, a new structure of frequency selective surface（FSS） is designed by replacing the cross cell center with a square ring and loading a square ring at each end of the cross. The improved structure and the traditional structure are analyzed using HFSS simulation software, and the angle stability and polarization stability of the two kinds of structures is compared. It is found that the new FSS structure is better than the traditional one both in polarization stability and angle stability. Finally, the newly designed structure is manufactured and tested under vertical incidence, and the test result agrees well with the simulation result.
