  • Patent number: 9048526
    Abstract: A resonant circuit and an antenna device achieve a low resonance frequency without increasing a coil size, and improve communication performance. In the resonant circuit, two coil-shaped conductors are arranged so as to be opposed to each other with a dielectric sheet interposed therebetween. The two coil-shaped conductors are, at the opposed portions thereof, coupled with a capacitance interposed therebetween, and wound so that electric currents flowing through the respective conductors trend in the same direction in a planar view. The opposed area in at least a portion of the outermost windings and/or innermost windings of the coil-shaped conductors is larger as compared with the opposed area in any other winding, and the respective ends of the conductors define power feeding units.

    Abstract: An antenna device includes an antenna coil, a magnetic core, and a metal member. The antenna coil is mounted on a flexible base. The antenna coil is wound in a loop shape or a spiral shape such that its winding center section is a coil opening section. The magnetic core passes through a slit opening section in the flexible base. The metal member has a rectangular opening. The antenna coil is exposed through the opening in the metal member. A front-side coil conductor is nearer the opening than the magnetic core, and thus a magnetic flux links the front-side coil conductor.

  • Patent number: 8638268
    Abstract: 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.
