  • Antenna formed from a plurality of stacked bases
    Patent number: 6781557
    Abstract: An antenna includes a plurality of bases stacked in a thickness direction, conductor patterns formed on the bases, respectively, and conducting sections for electrically interconnecting the conductor patterns. The conductor patterns form inductance components and capacitance components.
    Type: Grant

  • Antenna
    Patent number: 6597315
    Abstract: A high gain antenna of a compact external dimensions enables various devices for processing radio signals to include the antenna within the internal circuitry, so that there is no need to extend the antenna and avoid a danger of breaking the antenna, and the external appearance of the device is improved. The antenna is constructed by connecting antenna elements and in series, in which each antenna element has an inductance sections and a capacitance sections connected in parallel in such a way that magnetic fields generated by the inductance sections are oriented to intersect with one another so as to increase the signal gain.
