Bandwidth enhancement of open slot antenna for UWB applications

A novel open slot antenna for bandwidth enhancement is presented. The bandwidth enhancement of the proposed antenna is achieved by cutting two notches along the invert-L shape open slot in the ground plane. The frequency range of the proposed antenna is from 2.3 to 10.9 GHz, which can cover the WLAN bands (2.4/5 GHz) and UWB frequency range (3.1–10.6 GHz). © 2007 Wiley Periodicals, Inc.
