Phase synthesis of conformal array antennas

A new phase synthesis method for planar and conformal arrays is presented. The method is based on approximate linearized equations for small phase cha nges in the excitations, which can be determined by the least-squares metho d and used iteratively to obtain the final solutions for the excitation pha ses. Several different kinds of contoured beams can be used in the same arr ay by using only phase shifters in the elements, as demonstrated in the cal culated synthesis examples.
