Abstract
In this article, we study the typical double square frequency selective surfaces (FSS) structure with its dual stop-band behavior. These frequency selective surface designs are etched over the FR4 substrate to attenuate the signal of 3–4.8 and 10.4–16.8 GHz frequency band and let transmit rest of other microwave signals. The unit cell structure consists of double square loop, and these two loops are responsible for the dual-band effect. In this article, we also study the performance and analysis of the double square FSS transmission mechanism with the help of the simulation software and also from the equivalent circuit model (ECM). This design of FSS was obtained by performing the parametric simulation which gives the most optimized result. On the other side, a simple equivalent model has been proposed the simple and reliable equation close to provide the understanding of the transmission mechanism. In this analysis, each and every parameter of the design under the parametric tuning on the structure of the FSS observes the effect in the resonance and bandwidth. On performing the parametric simulation for the optimized resultant transmission coefficient S21, it provides the capacitance (C) and inductance (L) relation with frequency [1]. The equivalent circuit modeling result is shown approximately in a good concord with HFSS simulation result.
