Abstract
In this study, a novel design of printed monopole antenna with band-notched function for ultra wide-band (UWB) applications is proposed .The antenna structure consists of a diamond-shaped radiating patch with stair-shaped slits and a ground plane with a pair of boomerang-shaped slots which provides a wide usable fractional bandwidth of more than 125% with notch band around 5.05-5.98 GHz. In the proposed design, by cutting a pair of boomerang-shaped slots in the ground plane, the usable upper frequency of the antenna is extended from 10.4 GHz to 14 GHz and a good impedance bandwidth can be obtained. To generate a band-notched characteristic, a pair of stair-shaped slits was cut at the diamond-shaped radiating patch. The simulated and measured results show that the antenna design exhibits an operating bandwidth (VSWR<2) from 3 to 14 GHz with the rejected band in 5-6 GHz to suppress any interference from wireless local area network (WLAN) systems. The antenna exhibits good radiation behavior within the UWB frequency range.

Keywords
