ABSTRACT:
The invention relates to a transition between a ridge waveguide and a planar circuit on which a conductor is provided. The transition includes at least one conductive link connecting the end of said ridge to said conductor between two contact points. According to the invention, the contact points face a common access provided for putting the conductive link in place. It is thus possible to implement the contact points industrially, e.g. by means of a thermocompression machine.
