Abstract:
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%, 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.
