heal.abstract	A broadband and low cost switched beam antenna suitable for WIMAX applications is presented in this paper. Present mobile terminal antennas are expected to show increased bandwidth as well as low-loss impedance matching while maintaining low-profile geometry. A custom Genetic Algorithm (GA) is used in order to optimize the proposed array's parameters regarding resonation frequency and radiation pattern. The optimized antenna exhibits small size (dimensions 12 × 12 cm), satisfactory directivity for mobile terminal applications of 6.2 dB over an operation bandwidth of 120MHz around the central frequency of 3.5 GHz. Simulation results and parameters range are exposed below followed by the according radiation pattern and variation of the simulated VSWR.	en
