Abstract
Beam forming network as a system of parallel coupled transmission lines with different coupling coefficients is proposed. The beam forming network feeds linear array that in its turn forms radiation pattern with sector shape. An eigenwave problem for an infinite system of infinite transmission lines is solved in frame of coupled wave theory. Also a problem of eigenwave excitation is solved in frame of the same theory. Relations describing wave amplitudes in output plane are obtained. Directivity multiplier of a linear radiating array that excited by the waves in the output plane is considered. The analysis demonstrates that application of new type beam forming network sufficiently improves radiation pattern shape in compare with radiation pattern of the array with beam forming network with identically coupled transmission lines.
