Abstract

1383918 Making waveguide couplers MARCONI CO Ltd 5 Oct 1972 [9 Nov 1971] 51906/71 Heading H1W A waveguide multi-aperture coupler is made by coating a mandrel with conductive material to form a first waveguide length, etching apertures in the material and filling the apertures with soluble material, providing a further length of waveguide over the apertures, and, finally, dissolving the material in the apertures. As shown, the first length is of semi-circular section and is formed on a brass mandrel (not shown) covered in oxide to prevent adhesion of a thin coating of copper applied thereto by electrodeposition. The apertures 6 are formed using known photolithographic and etching techniques, after which they are filled with epoxy resin. Electrodeposition is continued to form a block 7 which is then machined to provide a channel 10 communicating with the apertures 6. The mandrel is removed and the material in the apertures dissolved using methylene chloride. A block 11, containing a slot 12 forming the second half of the further waveguide length, is attached by bolts (not shown) to the block 7. A coupling between two semi-circular waveguides may be formed by the same method. In a modified method, the semi-circular waveguide is coupled by two rows of apertures to the broad face of a rectangular waveguide which, like the semi-circular guide, is made by depositing material on a mandrel.
