Abstract
The paper considers an infinite two-dimensional ultra-wideband two-section antenna array in which the first section is made in the form of an isolated block connected to the second section via a special transition. Based on an approximate solution of a boundary value problem, an analytical model of the transition, making it possible to calculate its scattering matrix, is constructed. The scattering and transfer matrices of the first and second sections of the array in the quasi-periodic excitation mode are found in the approximation of the theory of microwave transmission lines. The total transfer matrix of the entire array is determined by multiplying the transfer matrices of its components. The numerically constructed analytical model of the array makes it possible to calculate its scattering matrix in the scan mode and has a high computational efficiency. The results of calculations by the proposed approximate model are compared with the results given by rigorous full-wave methods.
