摘要: 为了减缩天线的雷达散射截面，该文提出一种新型带阻频率选择表面结构(FSS)。对于入射电磁波，该结构与传统方环结构相比具有窄阻带和宽通带特性。因此该结构能代替天线的传统金属地板从而减缩天线的结构项雷达散射截面(RCS)。仿真与测试结果表明该结构作为天线地板可很大程度的减缩天线的雷达散射截面。Abstract: A novel stop-band FSS structure which is used to reduce the RCS of antenna is presented in this paper. For incident waves, the proposed structure has narrow stopband and wide pass band. Hence, the conventional metallic ground plane can be replaced with the proposed FSS to reduce the RCS of antenna. Simulated and experimental results show that the RCS of antenna is reduced considerably with the proposed FSS ground plane.
