Abstract

1275940 Flexible waveguides TELEFUNKEN PATENTVERWERTUNGS GmbH 6 Oct 1969 [5 Oct 1968] 49052/69 Heading H1W A flexible waveguide for simultaneous transmission of two mutually perpendicularly plane polarized electromagnetic waves is formed by a metal tube having a substantially constant cross-section of substantially square internal outline with rounded corners, the wall thickness of the tube varying circumferentially, as shown, such that bending on torsion of the tube causes minimum distortion to the internal outline of the tube. The opposite inside surfaces of the waveguide may be either parallel, or curved slightly outwards, as shown.
