| titleOfInvention | Multimode coupling system including a funnel-shaped multimode coupler |
| abstract | MULTIMODE COUPLING SYSTEM INCLUDING A FUNNEL-SHAPED MULTIMODE, COUPLER Abstract A multimode coupling system for coupling symmetrical waveguide mode signals and two or more tracking asymmetrical waveguide mode signals includes a funnel-shaped coupler with a plurality of coupling apertures located in the side wall thereof. A first four of these side wall apertures lie in a first common plane at a given distance from the small aperture end of the coupler. A second four of these apertures lie in a second common plane a second given distance from the small aperture end of the coupler. A first coupling circuit is provided between the first group of side wall apertures and an asymmetrical mode terminal, and a second coupling circuit is provided between the second four apertures in the second plane and a second asymmetrical mode terminal. Each coupling circuit includes a separate filter for each aperture, with the filters coupled to the first four side wall apertures adapted to pass signals at a first frequency band and with the filters coupled to the second four side wall apertures adapted to pass signals at a second frequency band. |
