The Physikalisch-Technische Bundesanstalt (PTB), Germany's national
metrology institute, is a scientific and technical higher federal authority
falling under the competence of the Federal Ministry for Economic Affairs and
Energy (Bundesministerium für Wirtschaft und Energie – BMWi). With its
scientific and technical service tasks, PTB measures with the highest accuracy
and reliability. It is responsible for representation and dissemination of the
units and ensures the unity of measurements. PTB undertakes fundamental and
applied research in the area of metrology in order to fulfill its tasks.
The working group Electromagnetic Fields and
Antenna Measuring Techniques, formerly headed by PD Dr. Thomas Kleine-Ostmann,
is responsible for field probe calibration, electromagnetic compatibility
testing and antenna characterization. Research in the working group aims at
establishing traceability for radio frequency measurement quantities ranging
into the mm-wave and sub-mm-wave range. In particular, measurement techniques
for signal properties based on oscilloscope measurements and for antennas and
the transmission channel based on vector network analysis are developed.
In the Meteracom project, PTB works on
establishing traceability to the SI for the measurements needed for the design
and operation of THz Communication Systems including channel sounding and
optical sampling techniques.
