Abstract
Disclosed is a distance measuring device, in particular for dielectric or metallic target objects, said device comprising a sensor with a resonance chamber and a resonance structure. The resonance structure has an element consisting of a dielectric material which has a narrowing at the edge, the resonance frequency of the resonance chamber being dependent on the distance between the element and a target object.
