Abstract
This paper examines the challenges encountered in the process of designing Frequency Selective Surfaces (FSSs) for applications that call for simultaneous coverage over very wide frequency band as well as wide angle. The paper begins with a review of existing literature and concludes that none of them can provide, even with the suggested modifications, a design that meets our needs of 3:1 bandwidth over an angular range of 60deg or higher. Next, we propose some new designs and examine how well we can meet the stated goals
