  • Conformal wide band surface wave radiating element
    Patent number: 9373895
    Abstract: Conformal antennas and methods for radiating radio frequency energy using conformal antennas are provided. In particular, one or more tapered feeds can be provided as part of or interconnected to a conductive top plate. The one or more tapered feeds have a depth that decreases from a feed point to a tip. The tip of the one or more tapered feeds is adjacent a cavity formed over a lens region. An aperture over the lens region can be covered or filled by an impedance surface. This impedance surface may comprise a frequency selective surface. Alternatively, a frequency selective surface can be provided over the lens region of an antenna incorporating one or more stripline feeds.

  • Two arm planar/conical/helix antenna
    Patent number: 4697192
    Abstract: A broadband two arm planar/conical/helix antenna is disclosed. The antenna radiation element includes a two arm planar spiral antenna section, a two arm conical spiral section connected to the planar spiral section and a four arm helix section connected to the conical spiral section for termination. The antenna element is formed on a fiberglas substrate which contains a molded internal load absorber. A tapered magnetic external load absorber covers the antenna radiation element. The supporting fiberglas substrate is fixed to a balun housing. The balun housing has a centrally disposed, upwardly extending tubular means for passing a feed line to the planar spiral section.
