1. 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%, andwherein 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.

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%.
