Abstract
Novel Angular and Polarization Independent Band-Stop Frequency Selective Surface for Ultra-Wide Band Applications
Highlights
Frequency selective surfaces are essentially two-dimensional infinite periodic structures [1]
Since the US Federal Communications Commission (FCC) released the frequency range of 3.1 GHz to 10.6 GHz for unlicensed usage in 2002, ultra-wide band (UWB) communication technology has become very popular among researchers
In UWB communication systems, ultra-short pulses are used for transmission and reception, and the spectrum spreads to a very wide frequency range [2]
Summary
Frequency selective surfaces are essentially two-dimensional infinite periodic structures [1]. The unit cell contains different length of square loop to obtain broad bandwidth from 10 GHz to 16.1 GHz. UWBFSS design exhibiting band stop filter from 2.5 GHz to 14 GHz is presented in [14]. In [17], a novel band stop FSS is presented and its unit cell consists of two metallic spirals with different lengths printed on both sides of a dielectric substrate. It has a stable transmission response with respect to various incident angles. The FSS is designed to exhibit the stable angular transmission response for both TE and TM polarizations of incident angle up to 60° under –3-dB transmission
