| Abstract: | An elliptical coplanar waveguide （CPW）-fed slot UWB antenna with band notch function was proposed. The total size of the antenna was 25mm × 26mm × 0.64mm. It had been studied experimentally for its impedance bandwidth, radiation patterns and gain by using CST software. As can be seen, within the operation bandwidth from 3.1 GHz to more than 20GHz, the voltage stand wave ratio （VSWR） is lower than 2, in which a frequency notched band from 5.1GHz to 6.2 GHz has been achieved. Good radiation performance over the entire frequency range has also been achieved. |
