  • the electromagnetic signal with high to extremely high frequency is generated during the emission directly in the measuring tip by the signal processing device which is only driven by a coupling signal with reduced frequency. This avoids negative influences of the measuring environment by attenuation and crosstalk.
  • the electromagnetic signals are preferably in the frequency range from 3 GHz to 300 THz. It is particularly preferred if the frequency range begins at at least 110 GHz.
  • the upper limit of the frequency range is preferably 30 THz at a maximum and particularly preferably 3 THz at a maximum.

Since the other components are always also contained in the coupling-out, i.e. inductive and resistive components are also present in the capacitive coupling-out, the term “essentially” is intended to clarify that the major component is intended to have the main importance.
  • the antenna has at least one Josephson junction.
  • the Josephson junction can be used at the same time for the signal processing device. This provides for particularly small integration with high resolution and measuring accuracy.
  • the measurement pick-up tip has preferably a Josephson junction in a control circuit in compensation mode, the microwave probe being constructed for determining other measuring quantities, for example temperature, magnetic field, topography of the object, distance between object and measuring tip, from the control signals of the signal processing device.
