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.

摘要： There is provided an antenna apparatus. A magnetic flux passing through a coil aperture of an antenna coil passes through a conductor aperture of a conductive layer, but the magnetic flux does not pass through the conductive layer. Accordingly, the magnetic flux is diverted to a path in which the conductor aperture of the conductive layer is the inside and the outer edge of the conductive layer is the outside. As a result, the magnetic flux passing through the coil aperture of the antenna coil makes a relatively large loop and links the inside and the outside of a coil conductor in an antenna in a communication partner with the antenna apparatus.
