Abstract: An information terminal apparatus includes a flat plate-shaped conductive housing including a first principal surface, a second principal surface, and a side surface that connects the principal surfaces, and a display provided on the first principal surface. The conductive housing includes a slit extending from the first principal surface to the second principal surface. Near the slit, a power feeding coil coupled to an IC element for an HF-band RFID system is disposed. The power feeding coil is magnetically coupled to the conductive housing via the slit. Thus, the conductive housing is utilized as a radiation element of the HF-band RFID system.

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 power supply coil is disposed on a rear surface of a display via a shield plate. When a current flows in the power supply coil, a magnetic flux emitted from the power supply coil traverses an opening of the shield plate. As a result, the power supply coil and the shield plate are electromagnetically coupled and the shield plate defines and functions as an antenna. Accordingly, a communication terminal communicates favorably with a smartcard, which is a device positioned on a front surface side of the display.

Abstract: An antenna device includes a first coil antenna and a second coil antenna. The first coil antenna includes a coil conductor having a rectangular or substantially rectangular spiral shape and located on a non-magnetic insulating base member. The second coil antenna includes two coil conductors located on a non-magnetic insulating base member. The two coil conductors are disposed and wound such that loops of a magnetic field that is generated by applying a current to the two coil conductors are perpendicular or substantially perpendicular to a coil axis of the coil conductors.

Abstract: An antenna device includes a feeding member including a coil pattern and an emitting member to emit a transmit signal supplied from the feeding member and to receive a receive signal and supplying it to the feeding member. The emitting member includes an opening portion and a slit portion communicating with the opening portion. When seen in plan view from the direction of the winding axis of the coil pattern, the opening portion of the emitting member and the inner region of the coil pattern overlap each other, and the emitting member and the coil pattern overlap each other at least partially.
