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: A watch with a built-in tag that includes a display displaying a time, a metal case having a through-hole in a side surface, a metal crown disposed to enable opening and closing of the through-hole, and a wireless communication device housed inside the case. The crown includes a head located outside the case and coming into contact with the case to close the through-hole, and a shank extending to the inside of the case through the through-hole with one end portion connected to the head and the other end portion located inside the case. When the head of the crown is pulled in a direction away from the case, the head of the crown becomes contactless with the case to enable a reader device located outside the case to read information of the wireless communication device through the crown.

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.
