Abstract
This tag reader can be applied to a chipless RFID tag having a plurality of resonance frequencies that are associated with identification information. The tag reader is provided with: a radiation unit that radiates electromagnetic waves within a predetermined millimeter wave or microwave frequency band so as to cause sweeping of the radiation frequency; and a detection unit that detects the plurality of resonance frequencies of a chipless RFID tag on the basis of the reflection characteristics of waves reflected from the chipless RFID tag when the electromagnetic waves are radiated.
