Abstract: An antenna device (201) includes a base (10) on which a planar conductor (11) is disposed and a coil antenna (100). The coil antenna (100) has a structure in which a coil conductor (21) is wound around a magnetic core (20). The coil antenna (100) is disposed such that the coil opening of the coil conductor (21) is closed to an edge of the planar conductor (11). The current a passing through the coil conductor (21) induces the current b in the planar conductor (11). Thus, the magnetic flux indicated by the arrow A occurs to the coil antenna (100), and the magnetic flux indicted by the arrow B occurs to the planar conductor (11). Therefore, the magnetic flux C occurs in the vicinity of the planar conductor (11). Accordingly, the antenna device having a small footprint and small-sized communication terminal apparatus are configured while a predetermined communication distance is ensured.

Abstract: There is provided at antenna apparatus capable of stably communicating with a communication partner and increasing the maximum possible communication range even when the antenna apparatus is relatively smaller than an antenna in the communication partner and the two antennas are disposed in close proximity on the same axis.
A coil window (CW) of an antenna coil module (3) and a conductor aperture (CA) of a conductive layer (2) at least partly overlap. A magnetic flux (MF) passing through the coil window (CW) passes through the conductor aperture (CA). On the other hand, the magnetic flux does not pass through the conductive layer (2). Accordingly, the magnetic flux (MF) is diverted to a path in which the conductor aperture (CA) of the conductive layer (2) is the inside and the outer edge of the conductive layer (2) is the outside. As a result, the magnetic flux (MF) passing through the coil window (CW) of the antenna coil module (3) makes a relatively large loop and links the inside and the cutside of a coil conductor (41) in an antenna (4) in a reader/writer.

Abstract: A coil conductor (31) of an antenna coil module (3) and a conductor layer (2) at least partially overlap. A current flows in the conductor layer (2) so as to block a magnetic field generated by a current flowing in the coil conductor (31). A current, which flows around the periphery of an opening (CA) of the conductor layer (2), flows along the periphery of a slit and around the periphery of the conductor layer (2) due to the cut-edge effect. Since magnetic flux does not pass through the conductor layer (2), magnetic flux MF attempts to bypass the conductor layer (2) along a path in which the conductor opening (CA) of the conductor layer (2) is on the inside and the outer edge of the conductor layer (2) is on the outside. As a result, the magnetic flux MF draws relatively large loops that link the inside and the outside of a coil conductor (41) of an antenna (4) on a reader/writer side. Consequently, an antenna device (101) and the antenna (4) on the reader/writer side are magnetically coupled.
