Abstract:
1. A wireless IC tag comprising: an RFID tag module; a plate-shaped rectangular ferrite core to which the RFID tag module is mounted; a primary antenna wound around a circumferential surface of the plate-shaped rectangular ferrite core, the primary antenna being connected with the RFID tag module; a pair of secondary antennas, each of the pair of secondary antennas being wound around a circumferential surface of the plate-shaped rectangular ferrite core and being connected with the RFID tag module, wherein the wireless IC tag is formed by molding the plate-shaped rectangular ferrite core in substantially the center of a columnar outer shell body such that a central axis line in a signal transmission/reception direction of the plate-shaped rectangular ferrite core fits together with a central axis line of the columnar outer shell body so that a signal transmission/reception surface of the plate-shaped rectangular ferrite core is opposite to an end surface of the columnar outer shell body, and wherein the primary antenna is wound around a substantially middle position on the circumferential surface of the plate-shaped rectangular ferrite core, and the pair of secondary antennas are wound separately around the circumferential surface of the plate-shaped rectangular ferrite core at both lateral positions of the primary antenna.
