A COMPACT MODIFIED TRIANGULAR CPW-FED ANTENNA WITH MULTIOCTAVE BANDWIDTH

This article presents the results of a compact modified triangular CPW-fed antenna that exhibits multioctave performance. This modification significantly improves the antenna's impedance bandwidth by 198% over an ultra-wideband (UWB) frequency range from 3.06 to 35 GHz. The return-loss (S-11) performance over this frequency range is designed to be better than -10 dB. These characteristics make the proposed antenna an excellent candidate for numerous UWB applications and next generation communication systems. The key physical parameters affecting the antenna's frequency characteristics have also been investigated to determine optimum antenna performance. The antenna's measured return loss and E-plane and H-plane radiation patterns show a very good correlation with the requirements of UWB applications. (c) 2015 Wiley Periodicals, Inc.
