CPW-fed printed slot antenna for WLAN/WiMAX and UWB applications

Abstract

A CPW-fed printed slot antenna for WLAN/WiMAX and UWB applications is presented in this paper. By using beveled step on both sides of trapezoid slot and tapered central line of the CPW feed line for impedance matching improvement, the proposed antenna capably responds to extremely wide impedance bandwidth from 2.2-10.7 GHz covering the operation frequencies of WLAN/WiMAX and UWB systems. Having shown radiation patterns likely omni-directional in xz and yz plane, the proposed antenna capably been applied for various WLAN/WiMAX and UWB applications.
