MANUFACTURING METHOD OF A WAVE-GUIDE FOR AN EMITTING-RECEIVING APPARATUS OF ELECTROMAGNETIC WAVES, AND WAVE GUIDE MANUFACTURED BY THIS METHOD

摘要

1. A waveguide for a transmitter-receiver of magnetic waves comprising a metallic envelope for guiding the electromagnetic waves, constituted by a silver layer (8) surrounded by a copper layer (11), characterized in that it comprises two flanges (9, 10) which are interconnected by the metallic envelope and which are maintained in position by the copper layer (11), the thickness of which is about 40 mu m, whereas the thickness of the silver layer (8) does not exceed 7 mu m, and that the copper layer (11) is surrounded by a sheath layer (12) made of plastic and thermally insulating material located in the interspace between the two flanges (9, 10).
