Abstract

The present invention discloses a radio frequency identification tag apparatus for a tire in a radio frequency identification system (hereinafter, referred to as a ‘RFID system’). The radio frequency identification tag apparatus for a tire in a radio frequency identification system, which has a reader for transmitting a strong radio frequency signal to peripheral areas, comprises: a substrate with a plurality of holes having a predetermined shape; a radio chip housed in the substrate, storing the characteristic information of the tire, and operated upon receipt of the radio frequency signal to modulate the characteristic information and output them in the radio frequency signal received from the reader; and an antenna housed in the substrate, having a symmetrically uniform flexion shape relative to the radio chip, receiving the radio frequency signal to provide the same to the radio chip, and receiving the radio signal containing the characteristic information from the radio chip to transmit the same in midair.

Claims
