Progress In Electromagnetics Research Letters, Vol. 11, 83-91, 2009
Abstract
In this paper, a coplanar waveguide fed (CPW-Fed) ultra-wideband (UWB) antenna with dual band-notched characteristics is proposed. Two symmetrical slots are etched from the ground plane to achieve the notched band at 5.5 GHz. The other notched band at 3.5 GHz is obtained by etching a split ring slot in the radiator. The simulation and measurement show that the proposed antenna achieves an impedance bandwidth of 3.1-10.6 GHz with VSWR < 2, except in the bands of 3.2-3.8 GHz and 4.8-6.2 GHz. A nearly omnidirectional radiation pattern and stable gain with variation less than 3 dB are also observed except in the two notched bands. Moreover, time-domain characteristics of the antenna are analyzed and discussed as well.
