  • Wideband conical spiral antenna
    Patent number: 6791508
    Abstract: A spiral antenna having a horizontal member that terminates wires for conducting and radiating signals provides increased efficiency over the HF transmission range in a smaller size construction. A load having a parallel RLC circuit is provided at about the center of the horizontal member. The wires are provided in an elliptical pattern with the spacing between wires provided arithmetically. The wires are further configured symmetrically around a vertical support member. A balun transformer is also provided for impedance matching with a feed line.
    Type: Grant
    Filed: June 6, 2002
    Date of Patent: September 14, 2004
    Assignee: The Boeing Company

  • Light transmissive electrically conductive oxide electrode formed in the presence of a stabilizing gas
    Patent number: 5135581
    Abstract: A light transmissive, electrically conductive oxide is doped with a stabilizing gas such as H.sub.2 and H.sub.2 O. The oxide is formed by sputtering a light transmissive, electrically conductive oxide precursor onto a substrate at a temperature from 20.degree. C. to 300.degree. C. Sputtering occurs in a gaseous mixture including a sputtering gas and the stabilizing gas.
