Compact CPW-fed Circular Slot Antenna for Ultra-wideband Applications

摘要：

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 30mm×33mm×1.57mm.The proposed antenna is simulated,fabricated and tested.Results show that a maximum relative impedance bandwidth of more than 130％ for |S11| < -10dB can be achieved,covering frequency range of 2.9-13.73GHz,which meets the demand of UWB applications.The effects of the structure parameters on bandwidth are investigated.
