Analysis of the elettromagnetic field and scattering of a slot antenna through hibrid 2D Wiener-Hopf technique and method of moment

The aim of this paper is to present an effective analytical approach in order to perform the analysis of the electromagnetic performance of a slot antenna. In this paper the main idea is to show how it is possible to get a closed form solution of the considered problem through the development ofa general analytical approach that let us consider the possible presence of any kind of linear stratified structure as loading medium in the shielded volume. In order to do that the double spatial Fourier transform is introduced, leading to a suitable formalism in the spectral domain rephrasing the electromagnetic problem in an equivalent circuit network model problem. The circuit network approach in the spectral domain yields a sort of Wiener-Hopf equation that can he analytically solved, through a suitable extended version of the Wiener-Hopf approach, or numerically faced and interactively solved with the requested accuracy through the Method of Moments in the spectral domain.
