ことを特徴とする誘電率測定装置。[Claims for Utility Model Registration] In a device that measures the dielectric constant of a measured object from the amount of attenuation and/or phase shift of the microwave when it is transmitted or reflected through the measured object, It is characterized by comprising a transmitting antenna that converts the microwave into a circularly polarized wave and radiates it to the object to be measured, and a receiving antenna that converts the microwave transmitted or reflected from the object to be measured from the circularly polarized wave to a linearly polarized wave. Dielectric constant measuring device.
