Novel design methodology for the generation of deterministic fractal antenna arrays

Fractal antenna design methodology is an artistic design methodology. That's why fractal antennas are also known as artistic antennas. This paper proposed a concentric elliptical ring sub array generator design methodology for a systematic expansion of deterministic fractal planar antenna arrays. Using this design methodology any polygon shape can be constructed. In this paper, a four element rhombic shaped fractal antenna array examined using this design methodology up to four simultaneous iterations and for different eccentric values. Due to recursive nature of fractals and proposed methodology, array elements brought down to 40 percentage and above of the total elements with a reduced side lobe level and beam width. The performance of proposed array shows better performance than four element fractal antenna array generated by concentric circular generator. These arrays are analyzed and simulated by MATLAB programming.
