Abstract: This report presents a novel design of concentric ring antenna array for a reconfigurable isoflux pattern. The array considers 61 disk patch antennas including mutual coupling by using the cavity model at the frequency of 2.8 GHz. The problem consists in finding out a few levels of excitations for the disk patch antennas. Harmony search algorithm and particle swarm optimization are implemented for this optimization problem. This novel design permits to reduce the complexity of the antenna hardware in the whole antenna system mounted in a satellite, where the volume occupation and heat dissipations are critical issues.
