Synthesis of aperiodic linear antenna arrays using genetic algorithm

In this paper, a genetic algorithm (GA) has been used to design the beampattern of the non-uniform linear array with minimum side lobe level and null control. The evaluation or cost function has been written for the array geometry with the goal of minimum side lobe level and null control in certain directions. Design examples employing the GA for finding the optimum element locations have been illustrated. Comparison with other existing techniques like, particle swarm optimization and quadrature programming method have been carried out.
