    Abstract: An antenna for a wireless IC device having improved energy transfer efficiency with a wireless IC, and a wireless IC device equipped with the antenna are obtained.
    An antenna (30) is composed of a coil pattern (31) and spiral coupling patterns (32a, 32b) formed at the ends of the coil pattern (31) and disposed so as to face each other. A coupling module (20) formed of a wireless IC chip (21) and a feeder circuit substrate (25) having a feeder circuit to be coupled to the wireless IC chip (21) is mounted on the coupling pattern (32a) to form a wireless IC device (1A). The coil pattern (31) is of an open type. The coupling patterns (32a, 32b) are close to each other to form a single LC resonator as a whole. Thus, energy is concentrated in the coupling patterns (32a, 32b), thereby improving the energy transfer efficiency between the antenna (30) and the wireless IC chip (21).

    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.
