Abstract
An optimal polarization beam pattern synthesis method based on particle swarm optimization is proposed in this paper. It is flexible to synthesize any state of polarization and arbitrary shape of power pattern. There is no limitation on the array geometry and element, and the proposed method is applicable for different array synthesis problems. Two typical examples, elliptical polarization synthesis with narrow main beam and linear polarization synthesis with shape main beam, are presented to show the potentiality of the proposed method.
