Résumé: Antenna arrays are widely used today for long distance communication with very high gains. The design of such antennas depends on certain parameters including the array excitation (amplitude and phase) and element positions. In this work, non-uniformly excited planar array optimization is done. Many shapes are considered: circular, Concentric Circular and hexagonal Arrays. The objective is to minimize the Sidelobe Level (SLL) for the arrays by finding the right element amplitude excitations. The study is performed on different number of elements for each shape. During this work the biogeography based optimization (BBO) has been used to minimize the sidelobe levels to converge to a designed mask. The optimal values obtained result in a good reduction of side lobe level for the different array shapes, although; the directivity had a small decrease depending on the shape, number of elements and other parameters.
