A new compact dual-band FSS with angular and polarization stability for wireless applications

Abstract

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 and dual polarized performances which are suitable for modern wireless communication systems. The FSS angular stability is investigated considering the incidence of waves at different angles. Additionally, an investigation is performed for different polarized wave incidence. Simulation results are compared to measurements ones for validation purpose. Good agreement is observed between simulated and measured results.
