Popis:	This paper presents the design of a circular array working at 2 GHz capable of generating two conical beam patterns with a semiangle of 30° and 90° respectively. The genetic algorithm was employed in order to obtain the characteristics of the array. Four parameters were optimized by using this method: number of rings, ring radius, number of elements in each ring and phase excitations. As a result, three arrays formed by 1, 2 and 4 rings (12, 33 and 66 elements) were selected.
