A novel broad and multiband frequency selective surface

Simulated theoretical results and experimental verifications are presented for a Frequency selective surface with slotted, perfectly conducting square patch elements.The frequency selective surface (FSS) structure acts like a band-reject filter having three broad stop bands in parts of C, X, and Ku band. Due to symmetrical nature of the design, the FSS is insensitive to variations of RF incidence angle for 90° rotations of the FSS. Simulated theoretical investigations are done by Ansoft Designer® software. Experimental investigation is performed using standard microwave test bench. © 2012 Wiley Periodicals, Inc.
