  • Wide bandwidth phased array antenna system
    Patent number: 6690326
    Abstract: A phased array antenna system in accordance with the present invention is configured to transfer signal energy between an antenna array and a source/target via multiple subbeams respectively carried in different frequency channels. Each antenna array element can thus receive a composite signal which can be band pass filtered to separate the different frequency channel signal components. By separating the signal components, a different phase taper can be applied to each signal component thereby enabling coherent signal energy to be derived from each antenna element. The derived signal energy can then be combined to produce an antenna input/output signal.
    Type: Grant
