heal.abstract	A multiobjective stochastic optimization technique is presented for the design of antenna arrays with given radiation pattern specifications. The technique utilizes the method of genetic algorithms and the proper objective functions are selected for the optimized array design. The technique has been implemented for the case where the arrays consist of vertical dipoles. The parameters of the GA include the elements positions, the array voltage excitation coefficients (amplitude and phase) and the radius and length of the dipoles. The array elements can either be arbitrarily placed, forming a non-uniform configuration or they can arange a circular, uniform, dual band array. In the latter case, the array and dipole characteristics are optimized by the GA for dual band operation, while different current coefficients have to be evaluated for each frequency. The presented results demonstrate the effectiveness, the versatility and applicability of the proposed technique.	en
