A reconfigurable frequency selective surface (FSS) is presented based on a nonuniform and finite array of square loop conducting patches printed on a dielectric substrate. The reconfigurability is performed changing the polarization of PIN diodes in the patch elements of the FSS array, from OFF to ON state and vice versa. Simulation is performed by the wave concept iterative procedure (WCIP) formulation...
This paper presents a simple, compact, and reconfigurable patch element geometry for multiband FSS applications. The patch element reconfigurability enables the development of reconfigurable FSS structures. The proposed FSS reconfigurability is theoretically and experimentally investigated through the use of small thin conducting strips on the FSS patch element geometry. Simulation is performed using...
This paper presents a compact dual-band dual polarized frequency selective surface (FSS) with angular stability for wireless communication applications. The proposed FSS element geometry is composed of a slotted cross dipole combined with four annular rings which are placed to provide symmetry along the conducting patch main axes. Simulation is performed using Ansoft HFSS software to ensure dual band...
This paper proposes a reconfigurable frequency selective surface (FSS) operating in the X band composed of triangular elements periodically placed on a single FR-4 dielectric layer. The reconfiguration of the proposed FSS allows a quasi-linear variation of the rejecting resonant frequency as function of the incident wave angle. The variation of the incident wave angle is provided by rotation of the...
An analysis of a fractal-like circular patch element for miniaturized frequency selective surfaces (FSSs) is presented. The analysis is performed using the Wave Concept Iterative Procedure (WCIP), a full-wave method. The proposed FSS geometry has a stable frequency response in relation to the oblique incidence of plane waves. In addition, the FSS patch element presents a fractal-like behavior, being...
