General synthesis method and its application to multi-feed EBG antenna

An efficient phase-only control method is presented to synthesize directive lobes for a multi-source feeding EBG antenna. The proposed method is based on iterative minimization of a function that incorporates constraints imposed in each direction with respect to excitation phases. The goal of using EBG antennas with min-max method is to create narrow beams to desired users with relatively low-sidelobes.
