Abstract

A waveguide coupling, in particular for a radar level indicator having a waveguide, a carrier plate and at least one feed line, wherein the waveguide is placed on a first side of the carrier plate on the carrier plate, the feed line is guided on and/or in the carrier plate into the inner area of the waveguide and the feed line terminates with an end in the inner area of the waveguide. The carrier plate is continuous in the inner area of the waveguide and thus extends beyond the end of the feed line, an electrically conductive coupling element is arranged near the end of the feed line on and/or in the carrier plate, so that the coupling element is capacitively coupled with the feed line and the coupling element serves to couple electromagnetic waves led into the waveguide via the feed line in the waveguide.
