Abstract
This paper describes the design and construction of a rotary joint based on two 3D-printed TE 01 mode transducers. The achieved operating bandwidth of the rotary joint is 25 GHz from 82 GHz to 107 GHz. The attenuation over the whole achieved bandwidth never falls below -4 dB at an amplitude variation of 1.25 dB over a whole rotation. The phase variation is less than 14.8° over a whole rotation, which makes this rotary joint suitable for channel-sounding and measurement purposes.
