Antenna Array Pattern Synthesis Using Metaheuristic Algorithms: A Review

In the field of wireless communication, antenna array plays an important role as it improves the gain, directivity, coverage area alongside provides beamsteering capability to the network that is an essential part of a 5G communication system. Antenna array pattern synthesis has received significant importance in communication as it aims at obtaining the radiation pattern close to the desired pattern. In antenna array excitation amplitude, excitation phase and distance between antenna elements are three parameters that can be optimized to obtain radiation pattern with minimum side lobe level, optimum null depth, and desired beamwidth. Metaheuristic algorithms are high-level search algorithms that have widely been explored for pattern synthesis of different array configuration. In this article author has discussed and compared the performance of different metaheuristic algorithms for uniform linear array (ULA), circular, concentric ring, conformal and planar antenna array pattern synthesis.
