  • Compact broad-band admittance tunnel incorporating gaussian beam antennas
    Patent number: 7889148
    Abstract: A plane wave antenna including: a horn antenna; a waveguide at least partially inside the horn antenna, wherein the waveguide includes: a central dielectric slab increasing in width toward the horn antenna and with a first dielectric constant, an upper slab above the central dielectric slab with a second dielectric constant, and a lower slab below the central dielectric slab with the second dielectric constant; wherein the central dielectric slab has a substantially constant thickness less than a quarter of a wavelength at a highest frequency of operation of the plane wave antenna.
    Type: Grant
    Filed: December 19, 2007
    Date of Patent: February 15, 2011
    Assignee: Arizona Board of Regents for and on behalf of Arizona State University
    Inventors: Rodolfo Diaz, Jeffrey Peebles, Richard LeBaron, Zhichao Zhang, Lorena Lozano-Plata
  • Aperture matched polyrod antenna
    Patent number: 7889149
    Abstract: A dielectric polyrod having at least one tapered section, where a section exposed outside of the waveguide is tapered a long a curve that depends on the dielectric constant of the material used. The invention also relates to an aperture matched polyrod antenna which includes the same and an inductive tuning element used to achieve wideband impedance match and to create a Gaussian beam in the radiating near field of the antenna, suitable to mimic a small region plane wave.
