Abstract

Fractal array antennas are multiband and broadband array antennas having space filling capability. But large Side lobe levels and the huge number of elements are the prominent challenges in the designing of these arrays. In this paper, analysis of linear and heptagonal fractal array antennas are investigated with a three valued Morse-Thue tapering technique. Due to this fractal tapering , a notable improvement has observed in array factor properties and thinning of the elements can be achieved at the various iterations of linear and heptagonal fractal array antennas. These array antennas are analyzed and simulated by MATLAB programming.
