Compact Orthomode Transducer with Broadband Beamforming Capability
A compact and broadband orthomode transducer (OMT) with two dual linearly polarized ports is reported here for the first time. The component is based on a combination of two ridged Boifot junctions through a series of power dividers that act as an embedded first level of the beamforming network. The design technique of the new OMT is discussed in the paper through an example that operates at Ku-band (10.7 GHz to 14.5 GHz) suitable for Satellite-on-the-Move (SOTM) user terminals. Measurement results of an additive manufactured (AM) monolithic prototype are presented, showing a good agreement with the simulation results.
