Patents by Inventor Jefferson C. Wingard

Jefferson C. Wingard has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 5268703
    Abstract: A decorative pole antenna and method is disclosed which includes an elongated, dielectric core which is wrapped with a decorative, "Christmas paper" like film having a well defined reflective pattern. An attachment ferrule is attached to one end of the core and a tuning coil includes space winding wrapped over the decorative film terminating at adjacent windings at the second end of the core. A transparent film is then shrunk over the entire assembly whereby the decorative film imparts a highly visible reflective pattern to the antenna in use without affecting the electrical characteristics of the antenna.

  • Patent number: 4868577
    Abstract: A unitary, multiband and dual polarity mobile antenna (A) is disclosed for vehicles and the like which includes a television antenna (B) having a horizontally polarized radiation pattern and a 2-way communications antenna (C) having a vertically polarized radiation pattern. A null current point (50) is created on communications antenna (C) by a phasing coil (34) which is intersected by a horizontal plane (52) in which television antenna (B) lies. This reduces cross-coupling, cross-polarization, and interference between the two antenna during operation. Horizontal television antenna (B) includes a J-folded, generally boomerang shaped, curved antenna configured to have a radiating element (20) and a half radiating element (22). These elements together form a third radiating element providing operation at three resonant frequencies.

  • Patent number: 4595928
    Abstract: A bi-directional antenna array is disclosed having at least two vertical loop antennas arranged mutually perpendicular individually operable to produce bi-directional scanning patterns shifted ninety degrees to achieve significant side rejection so that a user can better utilize the congested frequency spectrum.

  • Patent number: 4250507
    Abstract: A directional horizontal beam antenna is disclosed having a pair of driven circular loop elements mechanically coupled and carried closely adjacent one another in a vertical manner producing a directional signal which may be shifted between vertical and horizontal polarization wherein the circular loop elements are formed by a plurality of flexible straight sections having a unique construction.
