摘要： A wireless-IC-device main component is disposed on a surface opposite to a surface for receiving signals from a reader/writer. The wireless-IC-device main component includes an insulating substrate, which is provided with a loop electrode and an electromagnetically coupled module coupled to the loop electrode. A signal from the reader/writer causes an eddy current to flow across a conductor principal plane of a metal article. The eddy current causes a magnetic field to be generated in a direction perpendicular or substantially perpendicular to the conductor principal plane of the metal article. Then, the loop electrode is coupled to the magnetic field. Thus, the wireless-IC-device main component functions as an RFID tag even for signals from the principal plane opposite to the wireless-IC-device main component. Thus, it is possible to reduce the cost of manufacturing a metal article, and to provide a wireless IC device using the metal article as a radiator.

摘要： An antenna for a wireless IC device having improved energy transfer efficiency with a wireless IC, and a wireless IC device equipped with the antenna are constructed such that the antenna includes a coil pattern and spiral coupling patterns provided at the ends of the coil pattern and disposed so as to face each other. A coupling module including a wireless IC chip and a feeder circuit substrate including a feeder circuit arranged to be coupled to the wireless IC chip is mounted on the coupling pattern so as to define a wireless IC device. The coil pattern is an open type coil pattern. The coupling patterns are arranged close to each other to define a single LC resonator. Thus, energy is concentrated in the coupling patterns, thereby improving the energy transfer efficiency between the antenna and the wireless IC chip.
