In this paper, we describe the use of real-coded genetic algorithm (GA) for design of reconfigurable dual-beam linear isotropic antenna arrays with phase-only control of discrete phase shifters. The problem is to find a fixed amplitude distribution that will generate two broadside symmetrical beams in vertical plane: a pencil beam with zero phases and a flat-top beam with discrete phases of a five-bit discrete phase shifter, with or without minimizing dynamic range ratio (amax/amin) of excitation amplitude distribution.
