Abstract
The paper presents a theoretical consideration of a two-dimensional array consisting of two series-connected parts: an infinite system of one-dimensional arrays of strip horns and an array of planar horns. The eigenwave problem for an infinite one-dimensional array of strip transmission lines k]which reduces to a singular integral equation with respect to the current on the strip k]is solved. An analytical solution for the current and an expression for the characteristic impedance of the principal T-wave of the array k]which is valid in the scanning mode k]are found. A model of an array with smoothly varying parameters that describes the operation of a one-dimensional array of strip horns in the approximation of a microwave transmission line is developed. In the same approximation k]a model of an array of planar horns and the entire two-dimensional two-section array is developed and its numerical study is performed.
