The properties of frequency‐selective surfaces (FSS) exploited in antenna systems are well known. The purpose of this article is to report some experimental observations made on the focusing properties of FSS by tapering the lengths of the array elements. Two FSSs with different tapers are used to study this effect. Both surfaces show increased gain over a range of frequencies. Mass reduction in the lens structure is thus obtained here by varying the element size of the FSS. © 1996 John Wiley & Sons, Inc.
