Abstract
A three-layer wide-band reflective Frequency Selective Surface (FSS) reflector with a high roll off band edge is proposed in this paper. Each layer of the structure is patch type FSS. The proposed FSS has merits of wideband response over S band and lower C band with bandwidth of 3.6 GHz for transmission < -10 dB with 94% bandwidth and significant stability for different incident angles up to 40 degree. The polarization insensitivity of the FSS also added an extra dimension of the structure. The simulation process as well as the experimental measurement process and ECM (equivalent circuit model) analysis of the FSS have been done. The good agreement in simulated, measured and ECM results verifies the wide stop band for the proposed FSS. The tunable and switchable transmission behavior of the FSS for variation in width of the internal air gap and lateral sliding of the middle layer of the structure respectively are also presented here.
