Abstract :This paper demonstrates double bow-tie frequency selective surface insert ignore into journalissuearticles values(FSS); geometry for X-band applications with a bandwidth value of 1.82 GHz and K$_u$-band applications with a bandwidth value of 3.44 GHz. Throughout this study, parametric analyses of the proposed structure are also performed. Alterations in the reflection and transmission characteristics of this specially designed structure by virtue of defined variables are analyzed. Those variables are determined by considering the geometric and material properties of the proposed structure. To analyze the reflection and transmission coefficients, two different simulators, namely the High Frequency Structure Simulator insert ignore into journalissuearticles values(ANSYS HFSS);, which is based on the finite element method insert ignore into journalissuearticles values(FEM);, and the Computer Simulation Technology Studio Suite insert ignore into journalissuearticles values(CST Studio Suite);, which is based on the finite integration method insert ignore into journalissuearticles values(FIM);, are used. The structure is validated via those two solvers. Good agreement is obtained by both solvers, and the results are compared in terms of frequency, return loss, insertion loss, and fractional bandwidth.
