Waveguide arrangement

Abstract

A waveguide arrangement for guiding electromagnetic waves in a cavity surrounded by conductive material is proposed, wherein the waveguide arrangement comprises a printed circuit board material having an electrically conductive, plate-shaped back, a substrate and a conductive layer arranged on a side of the substrate facing away from the back. According to the invention, it is provided that the back has a surface structure, preferably formed by at least one recess, by which the waveguiding cavity is at least partially directly bounded; and/or that the cavity is formed in split-block technology by joining the printed circuit board material as split-block bottom part with a corresponding cover as split-block top part.
