MUMBAI, India, Jan. 2 -- Intellectual Property India has published a patent application (202541123095 A) filed by Cvr College Of Engineering, Hyderabad, Telangana, on Dec. 6, 2025, for 'dual polarized c-band orthomode transducer for collocated/frequency reuse satellite earth stations.'
Inventor(s) include Dr L Nageswara Rao; and Ch V R S Gopala Krishna.
The application for the patent was published on Jan. 2, under issue no. 01/2026.
According to the abstract released by the Intellectual Property India: "Earth station antennas employ Orthomode Transducers (OMTs) to combine or separate two orthogonal polarization signals in the feed system of antennas. OMTs have a common port and two orthogonally placed ports for simultaneous transmission of dual polarized signals. The common port is a square and the other two pots are of rectangular cross sections. The transmit C-Band (5.85 to 6.425 GHz) OMT allow propagation of both vertical and horizontal signals. The separation of polarizations is implemented in the coupled port and direct ports with flared waveguide. A compact OMT has been designed, simulated and tested for its RF performance. The return loss of all three ports is better than the -19 dB, port to port isolation of 40dB and XPD of more than 35dB with minimum insertion loss across 5.85 to 6.425 GHz. With the above measured performance, the OMT can be used in frequency reuse/collocated satellite earth stations."
