A new reconfigurable wide coverage pattern by optimizing a microstrip patch antenna array

This research presents a design of a microstrip patch antenna array for a reconfigurable wide coverage pattern. The antenna array regards disk patch antennas modeled by the cavity model as well as coupling effects at 2.8 GHz. The results can reduce considerably hardware complexity of the antenna array mounted in a satellite at different altitudes. The well-known particle swarm optimization is performed to obtain the optimal values of voltage excitations.
