Abstract
The invention utilizes two nominally orthogonal probes to couple selectively to two orthogonal modes propagating in a microwave waveguide and horn. The waveguide and horn utilize internal ridges to obtain broad bandwidth and the two probes are located in substantially the same plane in order to avoid introducing large changes in the relative phases of the two modes propagating within the waveguide with changes in frequency over the operating bandwidth of the device. The middle portion of each probe is bent or deformed to the extent needed to avoid physical conflict and electrical contact between the probes, while still avoiding the introduction of substantial phases differences between the modes excited by the respective probes.
