Abstract
The present invention is an orthomode transducer (OMT) device that allows for dual polarized dual frequency band antenna feed systems. The OMT device includes a waveguide structure having a first end and a second end such that the first end defines a port for receiving signals. The waveguide structure includes an outer wall defining a waveguide chamber therein and the outer wall 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 and extends towards the first end of the waveguide structure. The OMT device further includes at least one waveguide coupled to the outer wall of the waveguide chamber which is in signal communication with the waveguide chamber through an opening in the region of the outer wall.
