摘要

<FONT face=Verdana>介绍了一种新型小型化频率选择表面（FSS），在圆环缝隙周期单元表面加载电容以缩小FSS尺寸，并引入法拉第笼结构以消除单元间的干扰. 对这种加载FSS进行了数值仿真和分析，提出了一种适用于1~4GHz频段的电容加载FSS谐振频率经验计算式，并在此基础上设计研制了谐振频率为2.45GHz的加载FSS，其物理尺寸仅为传统FSS的百分之三十四，仿真和实测结果表明该FSS具有谐振频率稳定、对入射波入射角不敏感、对TE、TM极化一致性好等优点.

Abstract

<FONT face=Verdana>In this paper

a miniaturized frequency selective surface (FSS) is presented. In this kind of FSS

each periodic cell consists of a ring slot loaded with ceramic chip capacitors for reducing the cell size

and Faraday Cage structure is introduced to eliminate the disturbance between unit cells. The loaded FSS has been analyzed and empirical formulas for calculating resonance frequency in the range of 1~4GHz is presented. The miniaturized FSS with high transmission at 2.45GHz has been designed by the empirical formulas. The dimension of the proposed FSS is miniaturized to 34 percent in comparison with the traditional FSS. The simulation and experimental result indicate that the loaded FSS has good polarized characteristic and very good stability to oblique incidence.
