About structure of solutions of synthesis problem of linear microstrip antenna array according to the prescribed power directivity pattern

The structure of solutions to the synthesis problem of linear microstrip antenna arrays according to the prescribed power directivity pattern (DP) is presented. By the methods of branching theory it is shown that the bifurcation of solutions depending on the value of parameter regularization for the. problems of the given class is characteristic. It allows us to localize the existence of solutions and to build effective iterative processes for finding them.
