Abstract
A wireless IC device includes a wireless IC chip, a coupling electrode, and a radiation plate. The coupling electrode includes coupling portions arranged to be coupled to the wireless IC chip and a pair of opposing ends. The pair of opposing ends are capacitively coupled to each other and oppose the radiation plate to be coupled to the radiation plate. The wireless IC chip uses the radiation plate as an antenna to transmit and receive signals having certain frequencies to and from an RFID system.
