Effect of Centre Antenna Element on Array Factor Properties of the Deterministic Triangular Fractal Array Antenna
This research article explores the effect of centre antenna element on the array factor properties of the deterministic triangular fractal array antenna of expansion factor two. This sub-array based fractal array antenna is designed based on the concentric elliptical sub array geometric generator methodology. An alteration of the fractal array geometry is considered in which one of the antenna element is placed at the centre of the each sub-array of the deterministic triangular fractal array. Owing to the centre antenna element side lobe ratios are diminished from −25dB to −52dB and −30dB to −41dB in the triangular fractal array of second and third iterations simultaneously, with little variation in the side lobe level angle and beam width.
