The potentialities of antenna arrays in many everyday applications are well-known. Because of the difficulty to obtain a realizable array to the desired radiation pattern it is huge the number of synthesis methods presented in literature. Each of them pretends to obtain an approximated radiation pattern with some characteristics. The parameters used to control the diagram are the array dimension, the distance between discrete array elements, the side lobe levels, the directivity, the first null beamwith, the half power beamwith_ and so on
