Abstract :
In this work a broadband waveguide orthomode transducer (OMT) operating at the entire WR12 band is presented. The compact size OMT is fabricated in split-block technique. It exhibits an insertion loss below 0.6 dB and return loss values for the horizontal polarization greater than 20 dB and for the vertical polarization greater than 17 dB at 69 - 90 GHz. The simulated isolation between the orthogonal polarization ports is better than - 65 dB across the 60 - 90 GHz band.
