Compact coplanar waveguide (CPW) fed slot antenna for ultra-wideband (UWB) application is presented. Many UWB antennas have been developed to cover the ultrawide operating bandwidth of the UWB systems with acceptable performance. Currently, the prospective applications of UWB technology are becoming clearer and clearer. The majority of UWB R&D activities have been focused on how to meet the specific requirements of forthcoming UWB systems. This paper will review the R&D of UWB antennas since 2002 with proposed design model. A 50-Ω coplanar waveguide transmission line is used to fed slot antenna. Various slits on the ground plane is done for bandwidth enhancement. CPW fed slot antennas are attractive due to low dispersion and ease of integration with active and passive devices. CPW-fed slot antenna exhibit perfect impedance matching, broadside radiation patterns, and low cross polarization. Analysis of the effects of various slot dimensions on the parameters of the antenna design has been done.
