Abstract
A UHF band RFID system according to the present invention includes a reader antenna that is composed of a matched-terminated open-type transmission line and is connected to a UHF band RFID reader, a first-type RFID tag installed, without being fixed to a managed object, in a managed object placement area in which the managed object is placed, and a second-type RFID tag that is fixed to the managed object and includes tag information for identifying the managed object. When the managed object is placed in the managed object placement area, the managed object is placed in a position where the reader antenna and an antenna of the first-type RFID tag are electric field coupled, and is also placed in a position where the reader antenna and an antenna of the second-type RFID tag are magnetic field coupled.
