摘要： There is provided at antenna apparatus capable of stably communicating with a communication partner and increasing the maximum possible communication range even when the antenna apparatus is relatively smaller than an antenna in the communication partner and the two antennas are disposed in close proximity on the same axis. A coil window (CW) of an antenna coil module (3) and a conductor aperture (CA) of a conductive layer (2) at least partly overlap. A magnetic flux (MF) passing through the coil window (CW) passes through the conductor aperture (CA). On the other hand, the magnetic flux does not pass through the conductive layer (2). Accordingly, the magnetic flux (MF) is diverted to a path in which the conductor aperture (CA) of the conductive layer (2) is the inside and the outer edge of the conductive layer (2) is the outside. As a result, the magnetic flux (MF) passing through the coil window (CW) of the antenna coil module (3) makes a relatively large loop and links the inside and the cutside of a coil conductor (41) in an antenna (4) in a reader/writer.

摘要： An object is to provide a radio frequency IC device capable of achieving impedance matching between a radio IC chip and a radiation plate in a wide frequency band, and achieving desired radiation characteristics over a wide range of frequencies. Another object is to provide a radio frequency IC device and a radio communication system that allow both long-distance and short-distance communication and, in particular, allow short-distance communication using a small amount of energy.
A radio frequency IC device includes an electromagnetic coupling module (1) having a radio IC chip (5) and a feed circuit board (10), and a radiation plate (15). An annular electrode (25) is disposed to be coupled to both a feed circuit of the electromagnetic coupling module (1) and the radiation plate (15). The radiation plate (15) serves as an electric-field radiation plate for long-distance communication, while the annular electrode (25) serves as a magnetic-field radiation plate for short-distance communication. The feed circuit board (10) may be removed, so that the radio IC chip (5) is coupled to the annular electrode (25) directly or with an interposer disposed therebetween.
