Sierpinski Fractal Binomial Tapered Planar Monopole Antenna for UWB Communication

摘要

A miniaturized planar ultra wideband (UWB) monopole antenna with second iteration Sierpinski fractal is presented in this paper. The impedance bandwidth of the proposed antenna covers frequency range from 3.1 GHz to 10.6 GHz. The proposed antenna has circular split ring slot to truncate the band above 10.6 GHz. The measured antenna gain varies from -0.3 dBi to 5 dBi within the passband. The group delay profile is almost linear within the passband which ensures that antenna is not dispersive.
