摘　　要：以十字环和正方环为基本单元结构,设计了一种多频段复合单元频率选择表面(FSS),利用基于矩量法的电磁分析软件Ansoft Designer对其性能进行了电磁仿真分析,仿真结果表明该结构有两个对入射角和极化方式都很稳定的频带,而且通过对该基本单元变形,分别调节正方环和十字环的凹槽深度及宽度,其工作频带间隔大小可以根据需要双向调节,这在通信系统中将有广泛的应用前景。A frequency selective surface（FSS） with compounded unit-cell and multi-band,using square loop slot and cross loop slot as the basic structure unit,is proposed in this paper.Ansoft Designer software package based on Method of Moment is used to analyze its electromagnetic performance.The simulation results show that the structure has the advantage of insensitivity to the incident angles and polarizations.By deforming the basic unit and regulating the depth and width of the slots respectively,the working frequency interval size can be easily adjusted as needed,it will have a wide range of applications in the communication system.
