    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 that includes coil antennas each having a coil conductor wound around a winding axis and a planar conductor including a surface and an edge end portion, the surface extending along the winding axis of the coil conductor, the edge end portion being adjacent to a coil opening of the coil conductor. A current flowing through the coil conductor induces a current in the planar conductor, this current produces a magnetic flux in a direction normal to the planar conductor, and thus the planar conductor acts as a booster antenna. The antenna device has directivity in the direction normal to the planar conductor because the magnetic flux produced by the coil antennas and that produced by the planar conductor are combined. This enables the antenna device to occupy a small area while achieving a predetermined communication distance.

    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.
