摘要：
A radio frequency identification tag (RFID) that extends a read range of an RFID reader, and an RFID system including the RFID tag. The RFID tag includes a tag antenna, an IC, and a bonding part electrically connecting the tag antenna to the IC. A complex conjugate of an impedance of the tag antenna is a value obtained by adding an impedance of the IC to an impedance of the bonding part. Thus, the RFID tag can achieve accurate impedance matching between the tag antenna and the bonding, smoothly perform data communication with the RFID reader, and extend the read range of the RFID reader.
