Synthesis of Thinned Linear Antenna Arrays with Fixed Sidelobe Level Using Real-Coded Genetic Algorithm
By
Progress In Electromagnetics Research, Vol. 75, 319-328, 2007
Abstract
In this paper, we propose an optimization method based on real-coded genetic algorithm (GA) with elitist strategy for thinning a large linear array of uniformly excited isotropic antennas to yield the maximum relative sidelobe level (SLL) equal to or below a fixed level. The percentage of thinning is always kept equal to or above a fixed value. Two examples have been proposed and solved with different objectives and with different value of percentage of thinning that will produce nearly the same sidelobe level. Directivities of the thinned arrays are found out and simulation results of different problems are also compared with published results to illustrate the effectiveness of the proposed method.
