Device for measuring the dielectric and/or magnetic properties of a sample by means of a microwave transmission measurement

Abstract

A device for measuring the dielectric and/or magnetic properties of a sample by means of a microwave transmission measurement, comprising a transmitting antenna and a receiving antenna that define a transmission measuring section in which the sample to be measured can be positioned, at least one transmission-side synthesizer for generating a high-frequency signal with a frequency between 800 MHz and 30 GHz, a frequency standard that is connected via a transmission-side low-frequency synchronization signal line to the transmission-side synthesizer and to which the transmission-side synthesizer is coupled phase-locked reproducible, as well as an evaluation unit which is connected at least indirectly to the transmission-side synthesizer and the receiving antenna. At least one receiving-side synthesizer is provided which is connected to the frequency standard via a receiving-side low-frequency synchronization signal line and is coupled phase-locked reproducible thereto and is furthermore connected at least indirectly to the evaluation unit.
