Abstract
Fractal antenna technology is geometry-based, not material based, that’s why novel design methodologies and novel fractal shapes helpful for further improvement of antenna parameters. Side lobe level is one of the prominent challenges at higher expansion (S) levels of fractal antenna arrays. This report primarily focuses on the design and analysis of heptagonal fractal planar array antenna, based on concentric circular ring sub array mathematical generator. Due to this new structure a notable improvement has observed in Directivity, Side lobe level and Side lobe level angle. These fractal arrays are analyzed and are simulated using by MATLAB programming.
