  • Passive anti-jamming antenna system
    Patent number: 8077104
    Abstract: System and method for improving the interference resistance of an radio frequency (RF) antenna system through passive prescreening of the RF energy incident upon the antenna. The invention physically partitions the RF environment into two or more sectors with respect to the direction of arrival of incident energy. The power level of the RF frequencies of interest incident upon each sector is determined such that whenever the power level exceeds a given threshold, the received signal from energy incident on that sector is modified.
    Type: Grant
    Filed: November 14, 2007
    Date of Patent: December 13, 2011
    Assignee: Science Applications International Corporation
    Inventors: Cordell Fox, Kevin Wing, Robert A. Murphy, David C. Priester
