  • Lower element ground plane apparatus and methods for an antenna system
    Patent number: 11177563
    Abstract: A lower element ground plane apparatus for maximizing ground plane surface area in an antenna system, the apparatus involving a lower element of a bi-element antenna and an array of monopole antennas coupled with the lower element of the bi-element antenna, the lower element of the bi-element antenna operable as a ground plane for the array of monopole antennas, whereby ground plane surface area is maximized.
    Type: Grant
    Filed: August 15, 2019
    Date of Patent: November 16, 2021
    Assignee: United States of America as represented by the Secretary of the Navy
    Inventors: Dennis G. Bermeo, Peter S. Berens, David W. Brock, Christopher C. Obra, Jessica L. Watson, Hoin Lim
  • Lens apparatus and methods for an antenna
    Patent number: 11038278
    Abstract: A lens apparatus for improving antenna performance, the apparatus involving a lens configured to at least one of focus, refocus, and refract electromagnetic energy for constructively adding gain in a far-field, the lens configured to operably couple with an antenna, whereby electromagnetic energy is omnidirectionally concentrated, whereby antenna gain and directivity are improved, whereby antenna efficiency and antenna frequency range are maintained, and whereby antenna complexity is minimized.
