%K Phased Array Antenna, Irregular Tiling, Enumerative Tiling, Optimization, Genetic Algorithm, Schemata %X In this work, an innovative methodology for the design of planar sub-arrayed phased arrays composed by irregular arrangements of vertical and horizontal domino-shaped tiles is presented. More precisely, the proposed design method is aimed at optimally synthesizing low and medium size arrays through a suitable customization of mathematical tiling theorems and algorithms. Thanks to the exploitation of a customized genetic algorithm (GA)-based optimization strategy, the retrieval of the global optimal solution for the problem of finding the complete tiling affording the minimum side-lobe level (SLL) is effectively yielded through the proposed approach. A set of numerical benchmarks is presented in order to assess the proposed sub-arraying technique for small-sized problems. %D 2017 %A N. Anselmi %A P. Rocca %A M. Salucci %A A.
