Abstract

A novel band-pass Frequency Selective Surface (FSS) working on L-band is presented in this paper. By means of the coupling effect of the metallic patches on three different layers, the distributed capacitance of the periodic structure is formed and therefore decreases the resonant frequency. Investigations on the structure variables are presented and a novel unit cell, whose size is only λ0/20, is proposed. Furthermore, the novel FSS structure has shown a quite stable response for different incident angles and polarization modes as for its symmetry and miniaturization configuration. In addition, the miniaturization performance is investigated and optimized by changing the parameter of the structure.
