As quantum computers require temperatures near absolute zero, cryostats are utilized to deliver such conditions. This necessitates thermal decoupling in the signal feedlines. This paper introduces contactless waveguide transitions as an alternative to the currently used coaxial cables. Specifically, we present a contactless transition for WRD650 waveguides. The structure was optimised for transmission within the frequency range of 10 GHz to 18 GHz and validated by measurement. Additionally, the transition exhibits a relatively low susceptibility to misalignments and a decreased dispersion in contrast to rectangular waveguides.
