Abstract
Official abstract text for this publication.
A wireless IC tag includes a wireless IC chip and two coil-shaped antennas. One end of each of the coil-shaped antennas is electrically connected to the wireless IC chip, and the other ends of the coil-shaped antennas are electrically connected to each other. The winding axes of the coil-shaped antennas are arranged at different positions, and the coil-shaped antennas have the same winding direction. A reader-writer includes an antenna connected to an information processing circuit. The antenna is electromagnetically coupled to the coil-shaped antennas for communication.
