Numerical solution of synthesis problem of flat microstrip antenna array according to the prescribed power directivity pattern

The variational synthesis problem of a flat microstrip antenna array according to the prescribed directivity pattern by power is considered. The mutual influence of their elements is taken into account in an approximation of the given surface currents distribution on the radiators. The effective computing algorithm of finding the nonlinear synthesis equations solutions of various types is proposed. These equations are Euler ones of the researched functional. The synthesis numerical examples of the space directivity pattern are presented.
