Abstract: An antenna device includes a base including a planar conductor disposed thereon, and a coil antenna. The coil antenna includes a coil conductor wound around a magnetic core. The coil antenna is arranged such that a coil opening of the coil conductor is closed to an edge of the planar conductor. A current passing through the coil conductor induces a current in the planar conductor. Thus, a first magnetic flux occurs in the coil antenna, and a second magnetic flux occurs in the planar conductor. Therefore, a third magnetic flux occurs in an area of the planar conductor. Accordingly, the antenna device achieves a small footprint, a small-sized communication terminal apparatus and a desired communication distance.

Abstract: A communication terminal in which a card antenna module is loaded into a terminal casing including an antenna is operated such that a degree of coupling between a terminal-casing-side antenna and a module-side antenna is minimized and that a module-side antenna has a desired frequency characteristic. The communication terminal includes a terminal casing including a terminal-casing-side antenna, and a card antenna module loaded into the terminal casing. The card antenna module includes a coupling coil which is disposed at a position close to the terminal-casing-side antenna and which is coupled with the terminal-casing-side antenna via a magnetic field, and a module-side antenna which is disposed at a position more distant from the terminal-casing-side antenna than the coupling coil.

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.
