Fractal Density

Fractal array antennas are multiband arrays having ultra wide band and space filling facility. But Side lobe levels and large number of antenna elements are the major designing challenges of these arrays. In this paper, design and analysis of octagonal fractal array antenna is investigated with Morse-Thue fractal density tapering technique (MTFDT). Due to the proposed technique, a remarkable improvement has observed in Side lobe levels and thinning of the elements can also be attained at the various iterations of octagonal fractal array antenna. These arrays are analyzed and simulated by MATLAB-15 programming.

Large Side

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.
