Abstract

A one-layer frequency selective surface (FSS) is proposed for wide-band and multiple-notch filtering applications. The structure consists of one or two pairs of modified square rings on one side of the supporting dielectric layer. Two, three and four notches are obtained by modifying the parameters involved. A parametric analysis concerning the frequency response in function of the substrate thickness is reported, demonstrating the possibility of changing the stop bands and providing design flexibility. By duplicating the structure on both sides of the FR4 substrate, a wide band is obtained, for both TE and TM polarizations. The devised FSS can be used for filtering in the Wi-Fi, Bluetooth and X bands for Automotive applications. The analysis is realized by full-wave electromagnetic simulation.
