    摘要： A radio frequency IC device achieves impedance matching between a radio IC chip and a radiation plate in a wide frequency band, and achieves desired radiation characteristics over a wide range of frequencies. A radio frequency IC device and a radio communication system allow both long-distance and short-distance communication and, in particular, allow short-distance communication using a small amount of energy. The radio frequency IC device includes an electromagnetic coupling module including a radio IC chip and a feed circuit board, and a radiation plate. An annular electrode is arranged to be coupled to both a feed circuit of the electromagnetic coupling module and the radiation plate. The radiation plate defines an electric-field radiation plate for long-distance communication, while the annular electrode defines a magnetic-field radiation plate for short-distance communication. The feed circuit board may be removed, so that the radio IC chip is coupled to the annular electrode directly or with an interposer disposed therebetween.

    摘要： A wireless IC device includes a wireless IC chip arranged to process a radio signal, a power-supply circuit board that is connected to the wireless IC chip and that includes a power supply circuit including at least one coil pattern, and a radiation plate arranged to radiate a transmission signal supplied from the power-supply circuit board and/or receiving a reception signal to supply the reception signal to the power-supply circuit board. The radiation plate includes an opening provided in a portion thereof and a slit connected to the opening. When viewed in plan from the direction of the winding axis of the coil pattern, the opening in the radiation plate overlaps with an inner area of the coil pattern and the area of the inner area is approximately the same as that of opening.

    摘要： A wireless IC device includes a cutout portion having no aluminum-deposited film that is provided at an end of an article package made of an aluminum-deposited laminated film, and an electromagnetic coupling module is provided at the cutout portion. The electromagnetic coupling module and the aluminum-deposited film of the package define a wireless IC device. A loop electrode, which is a magnetic field transmission auxiliary radiator of the electromagnetic coupling module, is coupled to the aluminum-deposited film of the package. Thus, the article package functions as a radiator of an antenna.
