摘要：
This letter investigates two different methods of null placement in uniformly excited beam-steered planar array. Both methods utilize control of excitation amplitude and phase of edge elements placed along the symmetrical axes of the array. The first method considers additional control in the presence of existing complex excitation, whereas the second method employes an additional control by redefining the excitation of edge elements. Effectiveness of the two methods has been illustrated through design examples of 22 x 22 and 41 x 47 planar arrays.
