Abstract
Provided are a device detecting the spatial variation of the complex permittivity and an article presence/absence detection system which are capable of detecting the presence or absence of an article by using a UHF-band RFID tag. A device detecting the spatial variation of the complex permittivity includes an RFID tag, a conductor electrode unit, and a dielectric tag base material. The RFID tag performs communication using an electromagnetic wave in a UHF band. The conductor electrode unit communicates with the RFID tag by using the electromagnetic wave in the UHF band. The dielectric tag base material is provided between the RFID tag and the conductor electrode unit and separates the RFID tag from the electrode unit.
