Beschreibung
Zusammenfassung:	A method of manufacturing a flat waveguide in which a hollow core of a soft metal is introduced into a steel tube, this assembly is then provided with two parallel flat faces by flattening the tube with the core on two sides, after which the core is removed by etching. By using a hollow core, elongation, contraction and tearing of the wall of the tube is prevented. The flat tube obtained by the method according to the invention has a smooth and regular inner surface and a uniform wall thickness.
