This paper presents a bandwidth enhanced, compact planar ultra-wideband antenna design
for wireless personal area communication (WPAN) applications. The proposed antenna has
fractal based geometry and is constructed using several iterations of a pentagon slot inside
a circular metallic structure. The partial ground plane of the basic radiator is tapered,
defected and a U slit is etched out from the microstrip feed to improve the− 10 dB| S11|
bandwidth. The proposed fractal based antenna has an impedance bandwidth from 2.9 GHz …
