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 5.5GHz. The other notched band at 3.5GHz 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{10.6GHz with VSWR < 2, except in the bands of 3.2{3.8GHz and 4.8{6.2GHz. A nearly omnidirectional radiation pattern and stable gain with variation less than 3dB are also observed except in the two notched bands. Moreover, time-domain characteristics of the antenna are analyzed and discussed as well.
