摘要： [Problem] To provide an RFID tag with a boost antenna, which can enhance a communication distance by combining a boost antenna with a small RFID tag, a conductor provided with an RFID tag with a boost antenna, and an RFID system including an RFID tag with a boost antenna.
[Solution] An RFID tag 300 with a boost antenna includes a boost antenna 100 and an RFID tag 200, wherein the boost antenna 100 includes: a radiation unit 10 which is conductive; a ground unit 30 which faces the radiation unit 10 and is conductive; and a short circuit unit 20 which connects one end of the radiation unit 10 and one end of the ground unit 30, and electrically connecting the radiation unit 10 and the ground unit 30 with each other, and wherein the RFID tag 200 is arranged at a position close to the short circuit unit 20 on the ground unit 30, wherein each of the boost antenna 100 and the RFID tag 200 has resonance characteristics.
