    • The disclosure describes a compact coil antenna that can operate even if the coil antenna is arranged closely to its conductor plate, and that has a high degree of coupling with a target antenna. A lower coil conductor part and an upper coil conductor part each have a substantially rectangular and spiral form, and the inner end of the lower coil conductor part connects to the inner end of the upper coil conductor part to be connected in series to the inner end of the upper coil conductor part. In the lower coil conductor part and the upper coil conductor part, the arrangement interval in parallel-to-axis parts including segments that are parallel to the direction of the axis of a magnetic-material core is shorter than the arrangement interval of segments in orthogonal-to-axis parts that are orthogonal to the axis of the magnetic-material core.

    • Coil units including windings are disposed on opposite sides across a virtual center line that is substantially perpendicular to a direction of positional displacement of a portable electronic apparatus that is to be disposed close to a reader/writer. The windings are connected in series through a conductor such that winding directions of the windings are the same. A difference in the communication performance between a case where the portable electronic apparatus is brought closer to a central portion of the reader/writer and a case where the portable electronic apparatus is brought closer to a position that is deviated from the central portion of the reader/writer can be reduced. In particular, even in a case where the portable electronic apparatus is brought closer to a peripheral portion of the reader/writer, a predetermined maximum possible communication range can be ensured.
