Scheming and Enlargement of Annular Ring Frequency Selective Surface for Dual Band Application

Abstract

Frequency selective surfaces (FSSs) have been the topic of rigorous investigations for widespread applications for more than five decades. Frequency selective surfaces generally consists of periodically arranged metallic patches of arbitrary geometries or complimentary geometry having aperture elements similar to patches within a metallic screen, these surfaces exhibit total reflection or transmission for the patches and apertures respectively. These FSSs can be applied as antenna reflectors, radome, absorbers, high impedance surfaces, and electromagnetic shields in the microwave and millimeter wave regimes. The purpose of this project is to design, simulate and fabricate microwave frequency selective surface for dual band application in various microwave communication systems to enhance their performance and functionality.
