  • Dielectric waveguide mixer
    Patent number: 5640700
    Abstract: A non-radiative dielectric waveguide mixer includes at least one conductive plate, a dielectric waveguide held on said conductive plate and a solid-state device disposed across said dielectric waveguide for mixing at least two high-frequency signals which are propagated in opposite directions along said dielectric waveguide. The non-radiative dielectric waveguide mixer may be combined with a high-frequency signal generator and an antenna mechanism to provide a non-radiative dielectric waveguide radar module.
    Type: Grant
    Filed: January 13, 1994
    Date of Patent: June 17, 1997
    Assignee: Honda Giken Kogyo Kabushiki Kaisha
    Inventors: Masahito Shingyoji, Hiroyuki Ando, Shigiki Kato, Hiroshi Uematsu
