Kind Code:
A1
Abstract:
An RFID tag (201) is provided with: an insulator film (60); an antenna configured from antenna conductor patterns (61, 62) formed on the insulator film (60); and an RFIC module (101) mounted on the insulator film (60). The RFIC module (101) is provided with an RFIC (2) and an impedance matching circuit. The impedance matching circuit is provided with a first coil (LA) and a second coil (LB). Further, the primary plane of the magnetic flux loops induced near the first coil (LA) and the second coil (LB) by the antenna is not parallel to the primary plane of the magnetic flux loops induced in the first coil (LA) and the second coil (LB).
