    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 high-frequency coupler and a communication device are compact, capable of efficiently communicating a large volume of data over a short distance and can be used in combination with a non-contact IC card. The high-frequency coupler includes magnetic-field-generating patterns and a surrounding pattern disposed around a periphery thereof, and is used to communicate a large volume of data over a short distance in a communication system that uses broadband frequencies. Out of the magnetic fields radiated in directions perpendicular or substantially perpendicular to the plane of the patterns from the magnetic-field-generating patterns, portions extending laterally in the plane of the patterns are blocked by the surrounding pattern, the magnetic fields are lengthened in a direction perpendicular or substantially perpendicular to the plane of the patterns and the communication distance is increased.

    摘要： A wireless IC device includes an electromagnetic coupling module, which includes a feeder circuit board having a wireless IC chip arranged to process transmission and reception signals mounted thereon, and a radiation plate. Linear loop electrodes provided in the radiation plate are electromagnetically coupled to planar electrodes located on a surface of the feeder circuit board. A signal received by the radiation plate drives the wireless IC chip. A response signal from the wireless IC chip is transmitted to the outside from the radiation plate. A frequency of the transmission and reception signals is substantially determined by inductance of the loop electrodes, capacitance between the loop electrodes and the planar electrodes, and stray capacitance generated between lines of the loop electrodes.
