A novel right-angle coaxial-to-single ridge waveguide transition with capacitive coupling is presented at X band. Contrarily to the state of the art, the coaxial inner conductor is not in DC contact with the ridge, and such a feature can be a considerable mechanical advantage in the manufacturing of high-performance systems. In addition to this, few geometrical parameters need to be optimised, thus simplifying the overall design with respect to traditional counterparts. Nevertheless, the whole X band can be potentially covered with a return loss better than 20 dB. An ultra-compact transition is designed, manufactured with stereolithography technology and tested in a back-to-back configuration. Good agreement between simulated and measured results is observed for a proof-of-concept prototype.

Abstract
A novel right-angle coaxial-to-single ridge waveguide transition with capacitive coupling is presented at X band. Contrarily to the state of the art, the coaxial inner conductor is not in DC contact with the ridge, and such a feature can be a considerable mechanical advantage in the manufacturing of high-performance systems. In addition to this, few geometrical parameters need to be optimised, thus simplifying the overall design with respect to traditional counterparts. Nevertheless, the whole X band can be potentially covered with a return loss better than 20 dB. An ultra-compact transition is designed, manufactured with stereolithography technology and tested in a back-to-back configuration. Good agreement between simulated and measured results is observed for a proof-of-concept prototype.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
