CPW Fed Wideband Printed Antenna for Wireless Communications

Abstract

A simple radiating structure for achieving omni-directional radiation pattern from a monopole antenna fed by a CPW feed is presented. The proposed antenna has a 2:1 VSWR bandwidth of 76% from 2.7GHz to 5.7GHz. Hence it is suitable for WLAN 5.2(5.15-5.35GHz) band, WiMAX 2.5/3.5(2.5-2.69GHz, 3.4-3.69GHz) bands, HiperLAN2 (5.47-5.725 GHz) and HiSWaNa (5.15-5.25GHz) wireless application bands. The simulated and measured reflection characteristics of the antenna along with the radiation patterns and gain are presented and discussed.
