Title:
DIELECTRIC SPECTROSCOPIC SENSOR
Document Type and Number:
WIPO Patent Application WO/2023/132027
Kind Code:
A1
Abstract:
The present invention is provided with: a connection line path (11); a transmission line path (14) to which an impedance conversion unit (12) is connected; and a measurement surface (13) that is brought into direct or indirect contact with a measurement target M, and outputs electromagnetic waves to the measurement target. The connection line path (11) has a first characteristic impedance that is the same as that of a dielectric spectroscopic system (20). The end of the impedance conversion unit (12) located closer to the connection line path (11) has the first characteristic impedance, and the end thereof located closer to the measurement surface (13) has a second characteristic impedance different from the first characteristic impedance.
