Abstract
A multimode coupling system includes a funnel-shaped coupling member having one coupling aperture at the narrow end thereof, one larger coupling aperture at the larger end thereof, and a plurality of coupling apertures in the side wall thereof. A first and second of these side wall apertures lie in a first common plane on diametrically opposite surfaces of the member. A third and fourth of these apertures lie in a second common plane orthogonal to the first and on diametrically opposite surfaces of the member. A coupling circuit is provided between the plurality of side wall coupling apertures and an asymmetrical mode terminal for advancing the phase of signals at the first and third side wall apertures approximately 90.degree. relative to the phase of signals at the second and fourth side wall apertures to thereby achieve coupling of asymmetrical mode signals between the larger end and the asymmetrical mode terminal.
