Design of Compact Dual Band-Stop Frequency Selective Surface for Shielding Application
2021
This paper introduces a compact dual bandstop frequency selective surface (F.S.S.) for shielding applications. The octagonal and square looped model projected in this paper act as a band rejects filter for the frequencies 2.4 GHz and 5 GHz. The proposed model simulated using CST MWS electromagnetic simulation software. The current distribution for the two resonance frequencies is analyzed well. The proposed unit cell provides a symmetrical shape which enable stable performance in both T.E. and T.M. mode. The angular stability was assessed in various angles of incidence from (0°–60°). In T.E. polarization, the transmission and reflection coefficient for second resonance frequency shifted by +0.5 GHz and −0.5 GHz.
