A dielectric spectrometry device, comprising:
- a sensor device comprising:
- an antenna section including a first coaxial line structure on a base substrate, wherein an open end of the first coaxial line structure is disposed on a side of the first coaxial line structure that is configured to contact a target sample,
- an open section including a second coaxial line structure on the base substrate, wherein an open end of the second coaxial line structure is disposed on a side of the second coaxial line structure that is configured to be exposed to air,
- a short section including a third coaxial line structure on the base substrate, wherein a center conductor of the third coaxial line structure is conductive with a ground at a side of the third coaxial line structure that is closer to the target sample,
- a first signal line on the base substrate,
- a load which terminates the first signal line, and
- a switch arranged on the base substrate, the switch configured to selectively connect to any one of the antenna section, the open section, the short section, or the load to a port of a reflection measurement device, and
- a calibration circuit configured to calibrate the reflection measurement device connected to the sensor device, wherein the calibration circuit controls the switch to sequentially connect the short section, the open section, and the load to the port of the reflection measurement device, allowing the reflection measurement device to perform reflection measurement, for each of the short section, the open section, and the load, and calibrate the reflection measurement device based on a result of reflection measurement.
