Abstract

In this study, we propose a new formulation based on a global method to model a rectangular waveguide array as antenna. Our method consists to combine the method of moment (MoM), the generalized equivalent circuit method (GECM) and Floquet modal analysis. Looking for rigor, simplicity and rapidity, we repose always on the simple discontinuity in an open rectangular waveguide. So, we extended our pervious works to study in first step an infinite rectangular waveguides array and we achieve with a finite one. For validation purpose, we consider two rectangular waveguides and we compered it whit the same structure studied by direct method in our previous study. Obtained numerical results are presented and discussed. A good agreement is shown and the boundary conditions are verified.
