Angle and polarization-independent bandstop frequency selective surface for indoor wireless systems

Abstract

A novel bandstop frequency selective surface (FSS) is presented. It has good frequency stability for horizontally, vertically, and circularly polarized waves, incident normally or at oblique angles. This bandstop characteristic can provide physical security to WLAN and other indoor wireless systems, whereas passing mobile/cellular phone and personal communication signals. © 2008 Wiley Periodicals, Inc.
