Abstract
The paper presents a numerical and numerico–analytical models of the radiation of an infinite cophased antenna array of TEM horns, including the model with metallization of the space between neighboring (in the E-plane) horns. The numerical model is based on the finite-element method, and the numerical model, on the integral equation, Galerkin, scattering matrix, and coupled-wave methods. The numericoanalytical modeling has shown that, in such arrays, an anomalously high backward radiation is observed and that the proposed numerico–analytical model can describe this effect both qualitatively and quantitatively.
