    摘要: A wireless IC device that is miniaturized, allows simple and low-cost mounting of a wireless IC, and eliminates the possibility of damage occurring to the wireless IC due to static electricity, and an electronic apparatus equipped with the wireless IC device, includes a wireless IC chip that processes transmission and reception signals, and a feeder circuit substrate that includes a resonant circuit having an inductance element. Feeder electrodes are provided on a surface of the feeder circuit substrate and are electromagnetically coupled to the resonant circuit. The feeder electrodes and are electromagnetically coupled to radiation plates and provided for a printed wiring board. The wireless IC chip is activated by a signal received by the radiation plates and a response signal from the wireless IC chip is radiated outward from the radiation plates.

    摘要: A wireless IC device includes a wireless IC chip for processing a transmission/reception signal, a printed wiring circuit board on which the wireless IC chip is mounted, a ground electrode disposed on the circuit board, and a substantially loop-shaped electrode that is electrically conducted to the wireless IC chip and disposed on the circuit board so as to be coupled to the ground electrode by an electromagnetic field. The ground electrode is coupled to the wireless IC chip via the substantially loop-shaped electrode to transmit/receive a radio frequency signal. A feeder circuit board including a resonant circuit and/or a matching circuit may be interposed between the wireless IC chip and the substantially loop-shaped electrode.

    摘要: An optical disc includes an electromagnetic coupling module mounted therein. The electromagnetic coupling module includes a wireless IC chip and a feeder circuit substrate in which a feeder circuit including a resonant circuit having a predetermined resonant frequency is disposed. The electromagnetic coupling module is electromagnetically coupled to a reflective film defining a metal thin film of the optical disc, and the reflective film defines an antenna or radiation pattern of the electromagnetic coupling module.
