- Abstract
In this paper, wideband characteristics of density tapered a!1'ays are clarified by comparing d irectly the airny factors and radiation pattems of 3 tapered airnys structures with airny factors and radiation pattems of equally spaced a1rnys. Calculated results for a density tapered distribution a!1'ay consisting of 30 elements claims that the a1rny can perfonn within a bai1dwidth of 2.5:1 with grating lobe levels lower than -7.8 dB. Additionally, this paper shows a method of deten nining the effectiveness of unequal spacing a1rnys in the design of actual antennas. This method is based on the calculation and analysis of input impedance of a!1'ay elements caused by mutual coupling effects among a!1'ay elements.
