  • Compact waveguide load
    Patent number: 7920034
    Abstract: A compact integrated waveguide load has a load section disposed within an interior region of the waveguide proximate to a closed end of the waveguide. The load section has a tubiform shape, with an exterior surface congruent with an interior surface of the waveguide and an interior surface defining a circumferential step within the waveguide. A method of making a compact integrated waveguide load includes providing a waveguide and placing electromagnetic wave absorbing materially circumferentially around the interior surface to create an inward step.
    Type: Grant
    Filed: December 9, 2010
    Date of Patent: April 5, 2011
    Assignee: L-3 Communications Corp.
