    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.

    摘要： An antenna includes a feeder terminal and a resonance circuit. The resonance circuit is defined by a capacitance element and an inductance element and includes first and second radiation plates. The capacitance element is electromagnetically coupled to the first radiation plate, and the inductance element is electromagnetically coupled to the second radiation plate. A radio IC device includes an electromagnetic coupling module including a feeder circuit substrate on which a radio IC chip is mounted, and radiation plates. The feeder circuit substrate includes an inductance element and a capacitance element. One of the radiation plates faces and is magnetically coupled to the inductance element. The other radiation plate faces and is electrically coupled to the capacitance element. The radio IC chip is operated by signals received by the radiation plates, and a response signal from the radio IC chip is radiated from the radiation plates.

    摘要： An antenna and a wireless communication device which are suitable for an RFID system and in which radiation characteristics are prevented from being changed as a result of impedance adjustment are configured such that the antenna includes a first loop electrode that has an external shape of a regular polygon or circle and that includes a pair of open ends, feeding portions arranged inside the first loop electrode, a second loop electrode connected to the feeding portions, and a coupling electrode that couples the first loop electrode and the second loop electrode to each other. The wireless communication device is obtained by coupling the wireless communication element which processes a high-frequency signal to the feeding portions.
