The proposed design methodology is based on the analytic definition of a set of reference tiling arrangements and a customized genetic algorithm (GA)-based strategy which is able to effectively and efficiently explore the solution space of the complete tiling configurations. Some representative numerical experiments are presented in order to verify the effectiveness of the developed synthesis technique for the tiling of large planar phased sub-arrays providing optimal side-lobe level (SLL) radiation performance.} }
