Abstract (en)
[origin: WO02057762A2] The invention relates to a resonant microwave sensor (1) for determining properties of a material (3) to be examined. These properties are determined by a high-frequency measuring of a reflection factor (r) of a high-frequency resonance signal that serves as a measured quantity for determining properties of a substance to be examined. The resonant microwave sensor comprises a microwave feeder (4) for supplying the high-frequency signals, a sensor waveguide (2), which is coupled to the microwave feeder (4), and comprises a spiral conductor (5) that is arranged inside the sensor waveguide (2).
