Coil antenna and antenna structure
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.
