Document Type and Number:
WIPO Patent Application WO/2016/174797
Kind Code:

Abstract:
A UHF band RFID system according to the present invention is configured by a termination-matched open transmission line, and is provided with: a reader antenna (102) connected to a UHF band RFID reader (103); an RFID tag of a first kind (104) which is installed in a management target object disposition area (110) on which a management target object (105) is disposed, the RFID tag of the first kind being installed without being fixed to the management target object (105); and an RFID tag of a second kind (703) which is fixed to the management target object (105) and has tag information for identifying the management target object (105). When the management target object (105) is disposed on the management target object disposition area (110), the UHF band RFID system is disposed on a position where the reader antenna (102) and an antenna of the RFID tag of the first kind (104) are subjected to electric field coupling, and is disposed on a position where the reader antenna (102) and an antenna of the RFID tag of the second kind (703) are subjected to magnetic field coupling.
