Mode Coupling by a Longitudinal Slot for a Class of Planar Waveguiding Structures: Part II - Applications

Coupling between two parallel-plate waveguides is investigated. Mutual excitation is due to a Iongitudinal slot in a common plate. The introduction of reflecting boundaries parallel to the slot allows one to model a number of planar waveguiding structures featuring a common coupling mechanism. Part II of this paper presents specific examples of the above approach along with numerical results. Examples include a rectangular coaxial transmission line, broadwall-coupled rectangular waveguides, coupled microstrips, and coupled microstrip and rectangular waveguide.
