Abstract
AbstractA two‐layer frequency‐selective surface (FSS) is proposed for the suppression of far‐side lobes of radiating elements as an extension of the single‐layer FSS that is used for the suppression of near‐boresight side lobes. Based on the affinity of the proposed structure with the Fabry–Perot resonator, a method is developed for its analysis and design. The limitations of the method of analysis are discussed. A guideline is given for the design of a double‐layer FSS structure for the suppression of far‐side lobes of a radiating structure. A double‐layer filter is designed, fabricated, and used in conjunction with several radiating elements which achieve suppressed side lobes in the angular range of 40°–50° by 15 dB. © 2003 Wiley Periodicals, Inc.
