  • Antennas
    Patent number: 6819296
    Abstract: A marine radar antenna has a single dielectric plate mounted in front of the waveguide polarization grid between two horn plates. A strip of dielectric material is secured to the upper and lower surfaces of the plate to form a forwardly and rearwardly facing step on each surface. The steps are located forwardly of the ends of the horn plates and are positioned to produce reflections substantially 180° out of phase with extraneous energy within the antenna. The dielectric plate is supported by a foamed plastics material within an outer radome.
    Type: Grant
    Filed: November 20, 2002
    Date of Patent: November 16, 2004
