Design and development of a compact orthomode transducer (OMT) for K-band is described in this paper. An OMT comprises basic square waveguide port, and it is employed to isolate the single direct polarizations in an orthogonally coupled port and direct waveguide port. This model is intended for K-band task and can be utilized in satellite correspondence systems. The symmetric RF power transmission is coupled to a standard port, and a flared waveguide segment is utilized. The configured OMT covers the 24.5–25.4 GHz recurrence band for direct port as well as a connected port. An executed structure has coefficients of reflection across the K-band at all ports better than −12 dB. An implemented structure has point-to-point segregation and is greater than 32 dB, and the insertion loss is about 0.35 dB across the K-band. CST simulator has been used to optimize and simulate the OMT. The constructed model is sensible for satellite systems.
