  • Patent number: 10038235
    Abstract: A multi-mode, multi-band antenna system for a handheld wireless device includes a Quadrafilar Helix Antenna (QHA) that radiates circularly polarized waves is fed by a co-axial cable. The co-axial cable is also used in combination with the QHA as a monopole antenna. Because of the distinct electromagnetic field patterns of the QHA versus the combination of the QHA and the co-axial cable operating as a monopole antenna, the cross coupling between the two modes is low. In certain embodiments the co-axial cable can itself be formed into a helix in order to reduce the physical length of the antenna system while maintaining an electrical length desired to supported certain frequency bands in the monopole mode. According to certain embodiments a post which also serves to increase the effective electric length of the co-axial cable and thereby support a lower frequency band is provided along the centerline of the QHA.

Each quadruple spiral element consists of four conductors. Each conductor is a one spiral turn of the quadruple spiral element. Said conductors have equal winding angle. The winding angle of all conductors does not change in the same quadruple spiral element. Conductors of neighboring (longitudinally) quadruple spiral elements have different winding angles. The antenna provides a sharp drop in AP at angles near the horizon and a small AP level in the lower hemisphere.

  • Patent number: 9819778
    Abstract: A power supply coil is disposed on a rear surface of a display via a shield plate. When a current flows in the power supply coil, a magnetic flux emitted from the power supply coil traverses an opening of the shield plate. As a result, the power supply coil and the shield plate are electromagnetically coupled and the shield plate defines and functions as an antenna. Accordingly, a communication terminal communicates favorably with a smartcard, which is a device positioned on a front surface side of the display.
