Synthesis of Dual Beam Pattern of Planar Array Antenna in a Range of Azimuth Plane Using Evolutionary Algorithm

Progress In Electromagnetics Research Letters, Vol. 62, 65-70, 2016
Abstract
In this paper a pattern synthesis method based on Differential Evolution Algorithm (DE) is presented to generate dual beam patterns from a planar array of isotropic antennas. These are cosec2 pattern and pencil beam pattern. These patterns are obtained by finding out an optimum set of common elements amplitude (for cosec2 pattern as well as a pencil beam pattern), and a set of phases, for cosec2 pattern only. 4-bit discrete amplitudes and 5-bit discrete phases are used to reduce the design complexity of feed network. The beam patterns have been generated in two different azimuth planes instead of one particular plane. The evaluated excitations are also verified by considering a range of arbitrarily chosen azimuth planes, where the patterns are generated with some minor variations of the desired parameters. Obtained results clearly established the effectiveness of the proposed method.
