  • 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
