A modified design of a single-layer ultra-wideband (UWB) Frequency Selective Surface (FSS) reflector is presented for microwave applications. The proposed FSS unit cell consists of a square-loop and a ring printed on opposite sides of a low-cost FR-4 substrate. With the optimized dimensions of the elements, the proposed FSS design provides a stop-bandwidth of 11.94 GHz (5.24-17.18 GHz). It is observed from simulation results that the proposed FSS design has a linear decreasing phase response in the desired band. Furthermore, the presented design provides a stable frequency response up to 45° oblique angle of incidence for both perpendicular (TE) and parallel (TM) polarizations.

Abstract
A modified design of a single-layer ultra-wideband (UWB) Frequency Selective Surface (FSS) reflector is presented for microwave applications. The proposed FSS unit cell consists of a square-loop and a ring printed on opposite sides of a low-cost FR-4 substrate. With the optimized dimensions of the elements, the proposed FSS design provides a stop-bandwidth of 11.94 GHz (5.24-17.18 GHz). It is observed from simulation results that the proposed FSS design has a linear decreasing phase response in the desired band. Furthermore, the presented design provides a stable frequency response up to 45° oblique angle of incidence for both perpendicular (TE) and parallel (TM) polarizations.| File | Dimensione | Formato | |
