  • Miniature, flush mounted, microwave dual band cavity backed slot antenna
    Patent number: 4130823
    Abstract: A miniature, flush mounted, microwave dual band antenna which radiates omirectional microwave signals from a single flush mounted cylindrical array at frequency bands separated by 1.5 octaves. The antenna has a Y-shaped cavity with the leg of the Y being taken up by a probe and surrounding dielectric block. The cavity resonates the lower frequency band energy primarily in the open non-dielectric spaces and resonates the higher frequency band energy primarily in the dielectric space.
    Type: Grant
    Filed: August 5, 1977
    Date of Patent: December 19, 1978

    Inventor: Gary R. Hoople
  • Cavity antenna
    Patent number: 4054876
    Abstract: A cavity antenna having an aperture which may be mounted flush to the gro plane. A chamber positioned above a rectangular resonant cavity allows the antenna to achieve normal bandwidth and normal gain with a very thin cavity depth.

  • Omnidirectional antenna
    Patent number: 4047181
    Abstract: A thin omnidirectional antenna suitable for mounting and operation flush to ground plane. A flat metal probe is sandwiched between a pair of dielectric vanes which are enclosed in turn by a pair of metallic T-guides within a radiating cavity. The design achieves resonance for efficient radiation within an electrically small cavity.
