Abstract: In antenna device, a coil conductor of an antenna coil module and a conductor layer at least partially overlap. A current flows in the conductor layer to block a magnetic field generated by a current flowing in the coil conductor. A current flows along the periphery of a slit and around the periphery of the conductor layer due to a cut-edge effect. Since magnetic flux does not pass through the conductor layer, magnetic flux attempts to bypass the conductor layer along a path in which the conductor opening of the conductor layer is on the inside and the outer edge of the conductor layer is on the outside. As a result, the magnetic flux generates large loops that link the inside and the outside of a coil conductor of an antenna on a reader/writer side to couple an antenna device and the antenna on the reader/writer side.

Abstract translation: 在天线装置中，天线线圈模块的线圈导体和导体层至少部分重叠。 A电流在导体层中流动，以阻挡由在线圈导体中流动的电流产生的磁场。 由于切边效应，电流沿着狭缝的周边和导体层的周围流动。 由于磁通不通过导体层，所以磁通试图沿着导体层的导体开口在内部的路径旁边导体层，并且导体层的外边缘在外部。 结果，磁通产生将读取器/写入器侧的天线的线圈导体的内外连接的大的环路，将天线装置和天线耦合在读取器/写入器侧。

Abstract: In antenna device, a coil conductor of an antenna coil module and a conductor layer at least partially overlap. A current flows in the conductor layer to block a magnetic field generated by a current flowing in the coil conductor. A current, which flows around the periphery of an opening of the conductor layer, flows along the periphery of a slit and around the periphery of the conductor layer due to a cut-edge effect. Since magnetic flux does not pass through the conductor layer, magnetic flux attempts to bypass the conductor layer along a path in which the conductor opening of the conductor layer is on the inside and the outer edge of the conductor layer is on the outside. As a result, the magnetic flux generates relatively large loops that link the inside and the outside of a coil conductor of an antenna on a reader/writer side.
