<p>The present invention is an orthomode transducer (OMT) device allowing for dual polarized dual frequency band antenna feed systems. The OMT device includes a waveguide structure having first and second ends such that the first end defines a port for receiving signals. The waveguide structure includes an outer wall defining a waveguide chamber therein and includes a first cylindrical section proximate the first end. The waveguide structure also includes a second cylindrical section proximate the second end and a region therebetween. At least one longitudinal groove is introduced proximate the second end extending towards the first end. The OMT device further includes at least one waveguide coupled to the outer wall of the waveguide chamber in signal communication with the waveguide chamber through an opening in the region of the outer wall. The waveguide includes an iris aligned within the at least one longitudinal groove of the section.</p> |
