The present paper presents the design and development of a dual-channel microwave rotary joint using coaxial waveguide as primary waveguide and rectangular waveguide as the secondary waveguide. Design is presented at 5.85–7.02 GHz with 20% bandwidth and at 14–14.5 GHz bands with 3.6% bandwidth using dual channel mode transducers exciting transverse electromagnetic (TEM) mode in the coaxial waveguide. Rectangular to coaxial waveguide transitions employing multi-stepped doorknob transitions are used to excite the TEM mode from the rectangular waveguide. The measured results for electrical parameters such as return loss, insertion loss of the dual-channel rotary joint are presented with 360° rotation of the rotary part with respect to the stator part.
