Abstract
An improved 90° waveguide bend has the following features: the waveguide bend has two waveguide connectors located perpendicularly to each other, the waveguide connectors have a square internal cross section having an edge length (a), between the two waveguide connectors there is provided an angular portion producing the 90° change in direction, the angular portion has externally to the 90° change in direction a chamfer as a delimiting wall for the waveguide bend, the waveguide channel being outwardly delimited by the chamfer, and the chamfer has in the plane of curvature a length corresponding to the edge length (a) of the waveguide connectors which are square in cross section, ±less than 0.5%.

A 90° waveguide bend, comprising:
- two waveguide connectors located perpendicularly to each other,
- wherein the waveguide connectors each has a square internal cross section having an edge length (a),
- wherein between the two waveguide connectors, there is provided an angular portion producing a 90° change in direction,
- wherein the angular portion has externally to the 90° change in direction a chamfer as a delimiting wall for the waveguide bend, a waveguide channel being outwardly delimited by the chamfer,
- wherein the chamfer has in a plane of curvature a length corresponding to the edge length (a) of the waveguide connectors which are square in cross section, ±less than 0.5%, and
- wherein the chamfer merges with two external compensating wall portions each located in an extension corresponding to respective outer wall portions of the two wave guide connectors.
A 90° waveguide, comprising:
- two waveguide connectors located perpendicularly to each other,
- wherein the waveguide connectors each has a square internal cross section having an edge length (a),
- wherein between the two waveguide connectors there is provided an angular portion producing a 90° change in direction,
- wherein, the angular portion has externally to the 90° change in direction a chamfer as a delimiting wall for the waveguide bend, a waveguide channel outwardly delimited by time chamfer,
- wherein the chamfer has in a plane of curvature a length corresponding to the edge length the waveguide connectors which are square in cross section, ±less than 0.5% and
- wherein the edge length (a) of the chamfer is the same for both E and H flux modes.
