GA optimization of transparent MIMO antenna for smartphone

Abstract

A shared aperture transparent MIMO antenna for smartphone is proposed in this study. Genetic algorithm (GA) is used to optimize the antenna geometry by interfacing Matlab tool and HFSS-EM simulator using visual basic (VB) scripting. The performance of transparent conducting film as an antenna element is enhanced through numerical simulation. An optimal antenna design is obtained through this optimization algorithm. The evaluated antenna’s electrical performance like VSWR, spatial correlation coefficient (SCC), and peak gain (dB) are desirable in the cellular frequency bands of 0.850GHz and 2.2GHz.
