    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 has a structure such that the size of a radiation plate and a radiation characteristic may be determined irrespective of an impedance of a wireless IC chip. The wireless IC device includes a wireless IC chip that is arranged to process transmission and reception signals, a spiral matching inductance element and a plane electrode that are located on a surface of a feeder circuit substrate, and a coil-shaped radiation plate located on a radiation substrate. Plane electrodes connected to both ends of the radiation plate are electromagnetically coupled respectively to the inductance element and the plane electrode. The wireless IC chip is operated by a signal received by the radiation plate, and a response signal from the wireless IC chip is radiated outside from the radiation plate.
