Abstract
An ultra-wideband (UWB), dual-layer frequency selective surface (FSS) is presented.This compact low-profile FSS has been designed as a reflector for UWB antennas. It can be inserted between a planar UWB antenna and a nearby parallel conducting surface such as a circuit board, screen, or a metal case, to isolate them and to prevent antenna impedance mismatch otherwise caused by the conductor. The measured transmission coefficient magnitude of the FSS is less than -10 dB over a 133% bandwidth and its reflection phase is appropriate for this and other similar reflector applications, over an UWB.
