Abstract	The paper presents efficient technique for full wave 3D EM modeling of electrically large arrays. Basically it consists in two steps: 1) the network parameters (Y,Z,S) of the array are calculated together with its radiation patterns when each of the elements is active, while all other elements are short-circuited; 2) radiation patterns are obtained by arbitrary combinations of feeding voltages by post-processing data from the first step. 3D EM modeling is facilitated decomposing the problem having geometrical symmetry and asymmetrical excitation into four fully symmetrical problems of quarter size. Matrix solution is accelerated using graphical processor unit (GPU). Thus, array problems of 400 and 900 microstrip patch antennas become doable in 6 hours and 1 day, respectively.
