Waveguide And Waveguide Arrangement With Waveguide Transition

A waveguide, comprising:

• a tubular, electrically conductive waveguide body;
• an electrically conductive foil, the foil comprising:
• at least one matching portion arranged within the waveguide body and extending along a propagation direction of the waveguide body;
• and
• at least one connection portion arranged outside of the waveguide body, for connecting the waveguide to a component;
• wherein the matching portion of the foil is tapered in the propagation direction of the waveguide and arranged to form a ridge protruding from a sidewall of the waveguide along part of the length of the waveguide;
• wherein the connection portion extends outside of the waveguide, in the propagation direction of the waveguide and in the same plane as the matching portion;
• and
• wherein the waveguide has a rectangular cross-section.
