Abstract
A novel planar ultra wideband (UWB) antenna using a third iteration Sierpinski gasket fractal shape with circular boundary is presented in this paper. Size reduction of the antenna is done by Sierpinski gasket fractal concept which offers 24% thinning and provides excellent bandwidth better than a equivalent circular monopole which is around 8 GHz (span from 3 to 11 GHz with VSWR<;2) corresponding to 114% impedance bandwidth. The band-rejection operation achieved at the WLAN (5.15-5.85GHz) band by adding defected ground structure (DGS) or slit in the ground plane. The measured antenna peak gain varies from 1.85 dBi to 6 dBi within the band and radiation patterns of the antenna are nearly omnidirectional. The simulated and measured results show good agreement with the UWB characteristic.
