Abstract
A polarization independent, double layer frequency selective surface on glass substrate is proposed that can transmit 900Â MHz and 1.8Â GHz GSM bands but inhibit transmission of wireless local area network (WLAN) bands, 2.4-2.5Â GHz and 4.98-5.825Â GHz. A parametric analysis is conducted to tailor the resonance frequencies at WLAN bands and the effect of each geometrical parameter on band stop response is investigated. Band stop responses of each FSS layer and the double layer final design are presented both numerically and experimentally. The simulation results showed a good agreement with the experimental results and supported the polarization independent behavior. In particular, very wide rejection bands are obtained (â10Â dB bandwidths more than 1.75Â GHz) for the 5Â GHz band, both numerically and experimentally, for vertical and horizontal polarizations, under normal incidence. The design can be used in double layer window glasses for protecting systems against interference with WLAN signals in indoor environments and buildings.
