A 6.5 - 50 GHz battery-powered compact rotary joint for polarization ellipticity measurements

A simple, efficient, and compact rotary joint has been designed, realized, and measured. It has been used intensively to perform polarization ellipticity measurements on various circularly polarized antennas (e.g., helical antennas and circularly polarized horns, used either individually or feeding a lens antennas) operating in millimeter-wave band (similar to 30 GHz).
