  • Antenna system with edge treatment means for diminishing antenna transmitting and receiving diffraction, sidelobes, and clutter
    Patent number: 5963176
    Abstract: An antenna shroud or clutter fence has edge treatment for redirecting or absorbing energy which would otherwise be diffracted in an undesired direction. The edge treatment can include an array of corrugations which are about .lambda./4 deep for scattering sidelobes. The array of corrugations can be parallel to either the E-wave component or the H-wave component. Alternatively, the edge treatment can include an array of antennas encased in a dielectric extension.
