Embodiment Construction
[0032] In the embodiment of the present invention, the RFID tag device may generally include a support and at least one RFID tag loop disposed on the support. As those skilled in the art can realize, the RFID tag circuit usually includes an IC chip and an oscillation circuit composed of an antenna coil and a capacitor. The antenna coil is used to receive the signal sent by the reader and transmit the required data back to the reader.
[0033] In particular, the aforementioned at least one RFID tag loop comprises at least two antenna coils, wherein each antenna coil is located on a different surface of said polyhedral structure. That is to say, each antenna coil is on one surface of the polyhedron structure, and any two antenna coils are not on the same plane of the polyhedron structure. The present invention arranges at least one RFID tag loop with at least two antenna coils on a support with a polyhedron structure, and makes each antenna coil on a different surface of the po...
