Abstract: This research introduces three new fractal array configurations that have superior performance to the well-known Sierpinski fractal array. These arrays are based on the fractal shapes Dragon, Twig and a new shape which will be called Flap fractal. Their superiority comes from the low Side Lobe Level (SLL) and/or the wide angle between the mainlobe and the side lobes which improves the Signal to Inter-Symbol Interference and Noise (S/ISIN) ratio. Their performance is compared to the known array configurations which are Uniform, Random, and Sierpinski Fractal arrays.
Keywords: Fractals, Antenna array, Random array, Uniform array, Planar array, Reliable array, Fractal array, Phased Antenna arrays.
