Abstract: The present invention relates to a UHF RFID tag, and provides a set of UHF RFID tag comprising a loop-patterned sheet on which a RFID chip is mounted so as to form a closed loop and a dipole-patterned sheet that is separate from the other. According to the present invention, loop-patterned sheets having simple form and small size can be mass-produced in a few simple types. A mounting process for a RFID chip on the loop-patterned sheets which require precise work can be simplified. In addition, a set of RFID tag according to the present invention can be applied in various environments by combining a few types of the loop-patterned sheet and various types of dipole-patterned sheets.
