A wave guide to microstrip transition is disclosed in which the substrate of the microstrip line is arranged parallel to and in the longitudinal direction of the wave guide. The microstrip conductor is connected to the wave guide wall by a strip-shaped conductor provided on the substrate and the base plate has a first portion which extends to the opposite wall and a second portion which is located opposite the strip-shaped conductor. The edge of the second portion forms with an edge of the strip-shaped conductor a high impedance transmission line so that a low-loss asymmetrical conductor structure is obtained.
