Numerico–Analytical Model of a Non-Planar Array of Horns

Abstract

A non-planar array of strip horns is considered. A model of this structure is constructed in the form of a Floquet channel with smoothly varying parameters. The Floquet channel of an infinite array of coupled striplines is chosen as a reference waveguide. The scattering matrix of the Floquet channel in the quasi-periodic mode is found in the approximation of the theory of microwave transmission lines. Expressions are obtained for the elements of the scattering matrix in the mode of excitation of a single channel of a non-planar array. In this mode, the directional pattern of the radiation of the array into a planar waveguide is studied.
