On the design of microstrip patch antenna array for uniform power density in a wide spatial range

摘要

This document reports a design of a microstrip patch antenna array for a uniform power density in a wide spatial range. The antenna array regards disk patch antennas modeled by the cavity model as well as coupling effects at 1.6 GHz. The obtained results can reduce considerably the volume occupation and hardware complexity of the antenna array mounted on a LEO satellite. The well-known particle swarm optimization is performed to obtain the optimal values of voltage excitations.
