  • Wide bandwidth base station antenna and antenna array
    Patent number: 6917346
    Abstract: A base station antenna array comprises a ground plane and a parallel array of antennas above the ground plane. The antennas each have a progression of radiating elements whose length increases in a direction away from the ground plane. A feed is connected to the antenna at a point nearest the ground plane.
    Type: Grant

  • Hybrid power tapered/space tapered multi-beam antenna
    Patent number: 6072432
    Abstract: An antenna system producing a multi-beam antenna pattern having reduced sidelobe levels with a uniform beam pattern includes an antenna having a plurality of co-linear arrays of radiating elements including central co-linear arrays each of which has an identical number of radiating elements and a pair of outermost co-linear arrays each having a single radiating element. Each of the central co-linear arrays receives the full power output from a corresponding output of a Butler-matrix feed network except for two of the central radiating elements adjacent to the two outermost co-linear arrays, which each share the output power from a corresponding one of the outputs from the Butler-matrix feed network with one of the outermost co-linear arrays.
