Abstract
For ultra-wideband (UWB) applications, a compact coplanar waveguide (CPW) fed fractal antenna is proposed in this article. The antenna is designed and analyzed by line fed partial ground CPW and full-grounded CPW. The performance of antenna was compared with transmission line fed, partial ground CPW and full-grounded CPW. The effect of parameters like loss of return, gain, SWR and directivity has been presented. Simulation results reveal that UWB has been achieved due to non-grounded CPW and multiband is achieved due to grounded CPW. There is a high level of enhancement in gain with the use of CPW. The simulation was carried out using the HFSS simulation tool and fabricated antenna scattering parameter was analyzed using a vector network analyzer.
