Sidelob suppression in unequally spaced antenna arrays

An approach of sidelob suppressing in radiation pattern of an unequally spaced array antennas is presented in this paper. The Particle Swarm Optimization (PSO) algorithm in combination with gradient methods was applied to determine elements positions in uniformly excited array. Presented approach is based on a symmetric and ideal arrays of isotropic radiators without mutual coupling. A few results of radiation patterns produced from arrays with even number of elements were presented.
