Abstract : The transition between a rectangular waveguide and a stripline is accomplished with an assembly which contains: a waveguide flange, a waveguide section, and a tapered wedge. The waveguide flange physically connects with the rectangular waveguide and the waveguide section. The waveguide section has the tapered wedge housed within it along its top, and is electrically connected to the ground planes of the stripline. The tapered wedge is electrically connected with the center conductor of the stripline, to provide a transition between the rectangular waveguide and the stripline. Optimum impedance matching and voltage standing wave ratio can be empirically determined in the assembly by inputting signals into the stripline or waveguide, and taking impedance measurements while moving a reflecting panel which rests behind the tapered wedge to different positions in the slotted waveguide section.
