By using thin substrates with a low-permittivity, the achieved experimental bandwidth covers the frequency band from 1 GHz to 69 GHz. This transition, using electromagnetic coupling between the bottom and top ground planes, is very useful and requested in component packaging, on-wafer measurements of microstrip based monolithic microwave integrated circuit and for interconnections in hybrid circuits including both microstrip and coplanar structures. %G English %L hal-01241506 %U https://hal.science/hal-01241506 %~ UNIV-NANTES %~ UNIV-RENNES1 %~ CNRS %~ INSA-RENNES %~ IETR %~ IETR_SRC %~ CENTRALESUPELEC %~ UR1-HAL %~ UR1-MATH-STIC %~ UR1-UFR-ISTIC %~ IETR-CUTE %~ IETR-ADH %~ TEST-UNIV-RENNES %~ TEST-UR-CSS %~ UNIV-RENNES %~ INSA-GROUPE %~ UR1-MATH-NUM %~ IETR-SUMIT %~ NANTES-UNIVERSITE %~ UNIV-NANTES-AV2022 %~ IETR-NANTES
