  • Variable slot conductance dielectric antenna and method
    Patent number: 4516131
    Abstract: A variable slot conductance dielectric wavequide antenna in which the transmission line and radiating aperture is formed in one continuous, integrated and homogeneous material. The radiated antenna beam pattern is controlled by varying the conductance of radiating slots using varied geometries for each of the slots.
    Type: Grant
    Filed: February 4, 1983
    Date of Patent: May 7, 1985
    Assignee: The United States of America represented by the Secretary of the Army
    Inventors: William T. Bayha, John Borowick, Richard A. Stern, Richard W. Babbitt
  • Frequency scan antenna utilizing supported dielectric waveguide
    Patent number: 4468673
    Abstract: A dielectric waveguide of rectangular cross-section has periodically spaced, transverse slots in its upper surface. When traveling waves of varying millimeter wavelength frequencies are applied to the waveguide, the slots perturb the waves resulting in radiation having a main lobe that scans as the frequency changes. The antenna is made rigid by the use of a dielectric support.

    Inventors: Richard A. Stern, Richard W. Babbitt, John Borowick
  • Radar dipole antenna array
    Patent number: 4015266
    Abstract: A microwave antenna system particularly adapted for a two channel monopulse adar tracking system having sum and difference feed networks and respective dipole antenna arrays coupled thereto wherein one of the arrays is operated as a passive reflector or director for the other array during the transmit mode but is operated together with the other array as an active receptor during the receive mode whereby sum and difference arrays are provided in order to obtain information necessary to determine angular tracking error signals.
