## Abstract It is shown that thin mushroom layers (high‐impedance surfaces realized as regular arrays of small patches at a small distance from a metal surface) can be used as radar‐absorbing structures whose performance does not change with the incidence angle for TM‐polarized waves. The key role

✦ Synopsis
Abstract
A novel electromagnetic Band‐Gap (EBG) scheme is presented for size reduction. The proposed structure can be considered as one kind of distorted Sievenpiper High Impedance Surface (HIS) in a spiral shape, while it becomes extremely compact in size. Its design is detailed in this study, and two experimental results are presented. © 2007 Wiley Periodicals, Inc.
