Abstract:
1. A wireless IC device comprising: a high-frequency device including a wireless IC chip, the high-frequency device is arranged to receive or transmit high-frequency signals in the UHF frequency band; a radiation element defining a radiator; a loop electrode coupled to the high-frequency device and the radiation element, and including a loop plane perpendicular or inclined relative to a plane of the radiation element; wherein the wireless IC chip and the loop electrode are electrically connected or electromagnetically coupled to one another; the loop electrode is arranged to generate a magnetic field in a direction parallel or substantially parallel to the plane of the radiation element and to induce an electric field in a direction perpendicular or substantially perpendicular to the plane of the radiation element such that electric field loops induce magnetic field loops and the loop electrode and the radiation element are electromagnetically coupled to one another.
