Two-Channel Hybrid Rotary Joint (WR75 SMA) for Polarization Axis of SATCOM-on-the-Move Antenna Systems

Source summary

Develop a two-channel rotary joint for the polarisation axis of a satellite-on-the-move antenna. One path uses a Ku-band waveguide and the other an L-band coaxial connection carrying additional reference and supply functions. It must fit the existing compact mounting, maintain connections through continuous rotation and support mobile satellite installations. The source includes mechanical/RF design, precision manufacture, characterisation, environmental tests, a prototype and reports. Repeated paragraphs on the page are one requirement, not separate corroboration.
