Desenvolvimento de uma FSS Banda Dupla para Aplicações em Paredes Inteligentes

This article presents the implementation of a dual band FSS for intelligent walls applications, covering the WiFi frequency bands, 2.4 GHz and 5.8 GHz. The four arms star geometry, associated to trapezoidal rings, are used, which allows a more flexible frequency response adjust. Initial project equations are introduced and the frequency response characteristics discussed. Numerical and measured results are presented for four FSS, verifying a good agreement, achieving, for the x polarization, a transmission coefficient of, at least, 15 dB of atenuation for each WiFi band.
