Abstract :
A compact circular slot antenna for ultra-wideband applications is proposed in this letter. The antenna consists of a circular patch and an open annulus, and is fed by coplanar waveguide. The total dimension of the antenna is 30 mmtimes33 mmtimes1.57 mm. The proposed antenna is simulated, fabricated and tested. Results show that a maximum relative impedance bandwidth of more than 130% for |S11| < -10 dB can be achieved, covering frequency range of 2.9-13.73 GHz, which meets the demand of UWB applications. The effects of the structure parameters on bandwidth are investigated.
