Abstract: An RFID tag component, an RFID tag assembly and an object to be identified attached with the RFID tag assembly are disclosed. An RFID tag component includes an insulating ring; a film antenna bonded to the inner peripheral surface of the insulating ring, the film antenna formed by connecting an IC chip with a metal loop antenna, the metal loop antenna being flexible so the film antenna adheres to the inner peripheral surface of the insulating ring along a circumferential direction after being bonded to the inner peripheral surface; and a conducting medium layer adhering to an outer peripheral surface of the insulating ring in the circumferential direction and partially surrounding the insulating ring so a slot is between two ends of the conducting medium layer. The conducting medium layer is inductively coupled with the metal loop antenna to radiate RF signals from the IC chip outwardly through the slot.
