Interconnection device for electronic circuits, notably microwave electronic circuits

An interconnection device for elements to be interconnected such as electronic modules or circuits, comprising:

• at least one transmission line coupled to a ground line, the two lines being produced on the bottom face of a dielectric substrate, the interconnection being made substantially at the ends of the transmission line and of the ground line, said interconnection device being flexible over at least a part of its length situated between the elements to be interconnected, said interconnection device comprising at least one metallization surface forming, on the top face of the dielectric substrate at least one coupling element for reinforcing the electrical coupling between the two lines, said metallization surface being electrically floating.
