Abstract

In this paper, a Band Pass frequency selective surface(FSS) superstrate was proposed for the WLAN applications. Proposed FSS structure is made up of ring slot and a Jerusalem cross, which are etched on two opposite sides of the dielectric substrate. Structure is designed on the FR4 dielectric substrate with a relative permittivity of 4.4, loss tangent 0.025 and a thickness of 1.6 mm. The proposed structure shows excellent band-pass response with respect to different incidence angles. It was found that a band pass response occur at the WLAN resonant frequency of 2.4 GHz. 3 dB bandwidth of the simulated structure is 1.30 GHz.
