The invention relates to a distance measuring device and a suitable method for determining a distance which provides for continuous determination of the distance which can therefore also be made discrete and in addition is easy to handle and provides for a large variety of applications. The distance measuring device comprises analytical electronics and a sensor facility, which comprises at least one coupling probe for feeding an emitted signal into a conducting structure with reflection body. Moreover, the conducting structure comprises a feeding block with a feeding area connecting an HF transceiver via a wave guide with dielectric support system to the coupling probe.
