Beschreibung
Zusammenfassung:	A printed circuit board for a radar level measurement device with a printed circuit board substrate is provided, wherein a microwave signal is coupled via a microwave conductor into a waveguide. A connection region on a front side of the printed circuit board substrate serves to receive the waveguide. A shape of a resonator shell is generated inversely by producing an annular peripheral recess whose wall has an electromagnetically reflecting coating on a rear side of the printed circuit board substrate. The annular peripheral recess on the rear side, together with a region surrounded by the recess, forms a resonator for the injected microwave signals.
