Covariance matrix adaptation evolutionary strategy optimization of patch antenna for wireless communication

Abstract

Covariance matrix adaptation evolutionary strategy algorithm is applied to optimize a dielectric loaded microstrip patch antenna. The optimization process performance is enhanced by not considering the symmetrical factor of the antenna structure. The antenna is optimized to work for IEEE 802.11a WLAN 5–6 GHz band. Experimental measurements have also been performed to validate the performance of the proposed antenna.
