Abstract
For acquiring data of dynamic physical processes via a radio link, a transponder antenna () is excited by an electromagnetic exciting wave at the resonance frequency of the transponder antenna (), and a back-scattered electromagnetic sensor wave which is modulated by a sensor () having an electrical impedance depending on the data to be acquired is received and analyzed. The sensor () is directly connected to the transponder antenna () such that the sensor changes the electrical impedance of the transponder antenna () with every variation of the data to be acquired. The electromagnetic wave which is back-scattered by the transponder antenna () is received as the sensor wave at the same time as the transponder antenna () is excited by the exciting wave.
