Abstract

In this manuscript, an angular stable and polarization-insensitive band-stop frequency selective surface (FSS) is designed for K - and Ka-bands. The design features a cross dipole element and a rhombus embedded ring element. The designed FSS exhibits a wide band-stop response ranging from 16.5 to 25.26 GHz, achieving a fractional bandwidth (FBW) of ≈42%. The physical dimensions of both the square frame and the shaped radiator play a crucial role in regulating the bandstop characteristics of the FSS. Optimum design parameters are determined through parametric analysis. Additionally, the transmission characteristics under non-normal oblique incident waves is investigated. It is observed that the FSS demonstrates angular and polarization stability in both horizontal (TE) and vertical (TM) polarizations up to 60° oblique angles.
