Abstract :
A 2-D choke structure is analyzed by the method of moments (MoM) for the study of isolation characteristics between closely arranged two waveguide slot array antennas. In this paper, two-dimensional (2-D) TE problem is considered. Parametric study is performed to understand the mechanism for obtaining the small coupling.
