Abstract

A new compact CPW-fed slot antenna for UWB applications is presented in this paper. The slot in the ground plane is asymmetric which helps in wide band impedance matching. The radiating element is a star-shaped geometry fed by a double stepped co-planar waveguide. Three antennas are designed with this geometry. Out of these three antennas, a compact antenna is proposed. The size of the proposed antenna is 27.2 x 32.2 mm², and it has a measured impedance bandwidth of 8.7 GHz (3-11.7 GHz). The radiation patterns are stable with respect to frequency and of bi-directional shape in E-plane and omnidirectional shape in H-plane. The measured and simulated results are in good agreement.
