An optimized shaped antenna for multiband applications using Genetic Algorithm

In this paper, a novel shaped microstrip patch antenna fed by microstrip lines is proposed. This antenna optimally designed, is achieved by applying Genetic Algorithm (GA) to find the optimum parameters for shaped configuration. The objective function constitutes a multi-objective optimization problem. The simulation and measured results show good multiband antenna suitable for applications operating at 2.4/3.6/5.5GHz (WLAN communications systems). Also, good antenna performances such as radiation patterns and antenna gains over the operating bands have been observed.
