| 摘 要： | 为了实现频率选择表面(FSS)的平顶传输特性.选取矩形栅格和传统圆环的组合图形为基本单元,设计了一种新型组合图形单元的FSS.利用谱域法对这种新型FSS的单屏结构进行理论计算和分析.计算结果表明,这种新型的FSS单屏结构能够给出陡峭边缘和平顶的宽频带传输特性,平顶带宽可达8 GHz;同时能够把相邻很近的信号带分离开从而实现双重通信,例如在X波段和Ku波段的信号,并且对不同入射角度的电磁波保持稳定的双带特性.

| Abstract: | In order to realize flat-top transmission property for frequency selective surface (FSS) structure, a novel composite element FSS composed of rectangle metal grid and conventional ring loop element is presented. By applying the spectral-domain approach, the novel free FSS screen is calculated and analyzed theoretically. As a result of the numerical analysis, it is shown that the flat-top passband of 8 GHz and sharper skirts, diplexing closely separated signal bands, for example, X- and Ku-band signals, can be obtained with the novel structures. In addition,the performance of double bands available can maintain stabe for different incidence angles. |
