In the case of antenna arrays, researchers usually neglect the effect of mutual coupling of antennas placed in proximity to each other. The interchange of electromagnetic energy between an antenna and a far-field point depends on not only the transmitting antenna, but also its neighboring antennas. This effect is referred to as mutual coupling between dipole antenna elements and is considered here in the synthesis of phase-only reconfigurable antenna arrays. The main objective of this work is to produce the desired side lobe level and voltage standing wave ratio, in addition to few other radiation pattern parameters. Multi-verse optimization algorithm is employed for the purpose of generating voltage amplitude and discrete phase distributions in the dipole elements to generate flat-top beam/pencil beam patterns. These two patterns share common amplitude distributions and differ in phase distributions. Results of simulations proved that this algorithm accomplished its task successfully and was superior to other algorithms like particle swarm optimization, grey wolf optimization, and imperialist competitive optimization algorithms.
