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