Abstract

Fractal array antenna design process depends on the repetitive geometric design methodology. Owing to this reason, these antennas are also named as artistic antennas. This research paper proposed a nonagon fractal array antenna designed using concentric elliptical ring sub array geometric generator for satellite and other advanced wireless based communication systems. The proposed nonagon fractal array have designed up to four iterations and for two different expansion levels. Owing to the recursive nature of fractal structures proposed are array exhibits multi-beam behaviour with fine array factor characteristics. The proposed nonagon fractal arrays are analyzed and simulated by MATLAB 15 programming.
