Antenna synthesis with flat radiating aperture according to the prescribed directivity pattern by power

The investigations of solutions of antenna synthesis problem with flat radiating aperture according to the prescribed requirements to the directivity pattern (DP) by power dependent on two physical parameters describing the electrical and physical sizes of aperture and solid angle, in which the necessary DP is given, are presented. It is shown that the non-uniqueness and bifurcation of solutions is characteristic features of this class of problems. The equation on finding such set of values of parameters at which bifurcation of solutions occurs, is found. Numerical algorithms for finding the optimal solutions of the synthesis problem are constructed. The numerical examples are given.
