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.
