3D Printed Dually Symmetric Orthomode Transducer and Horn Antenna at X-Band

A dually symmetric orthomode transducer (OMT) and horn antenna are presented for both single port linearly polarized operation dual circular polarization use. The feed uses two waveguide splitters a bend to four-port that has the groups of ports orthogonal each other produce radiation pattern. is printed from 316L stainless steel while plastic polymer metallized using aluminum tape. structure based on WR 90 covers guide’s full operating band 8.2 GHz 12.4 GHz. Peak realized gain values 20.5 dBi were measured with cross rejection over 40 dB. Here circularly results presented, latter an off-the-shelf hybrid control phase ports. Enabled by feed, linear patterns highly symmetric.
