Hybridization of fractal geometries in monopole antenna for UWB applications

Abstract

In this paper, ultra-wideband fractal monopole antennas are investigated which are formed by hybridization of Giuseppe Peano and Sierpinski Carpet fractal geometries. The comparative analysis is shown between three monopole antennas which are designed by applying Giuseppe Peano fractal geometry on the edges of rectangular slots of Sierpinski Carpet fractal geometry in outer and inner boundaries. The comparison is done on the basis of resonant frequency bands and -10 dB impedance and VSWR (less than 2) bandwidths. The antennas are fed through a microstrip line with a matching section having characteristic impedance of 50Q above a semi-elliptical ground plane. These antennas are utilized in ultra-wide band (UWB) communication applications.
