The problem of reducing beam overlap in a multiple-beam planar array is investigated. A planar array of point sources radiates three separate beams. By using only phase adjustments, the synthesis algorithm minimizes the sidelobe level of each beam in the vicinity of the other two main beams. The conjugate gradient method is used to solve the system of equations for the unknown phases on each radiator. Antenna arrays, Array synthesis, Conjugate gradient method, Multiple-beam antennas.
