  • Multi-mode input impedance matching for smart antennas and associated methods
    Publication number: 20060022889
    Abstract: A smart antenna includes a ground plane, an active antenna element adjacent the ground plane and having a radio frequency (RF) input associated therewith, and passive antenna elements adjacent the ground plane. Impedance elements are connected to the ground plane and are selectively connectable to the passive antenna elements for antenna beam steering. Tuning elements are adjacent the passive antenna elements for tuning thereof so that an input impedance of the RF input of the active antenna element remains relatively constant during the antenna beam steering.

  • Broadband smart antenna and associated methods
    Publication number: 20060022890
    Abstract: A smart antenna includes a ground plane, an active antenna element adjacent the ground plane, and passive antenna elements adjacent the ground plane. The passive antenna elements have different sizes for defining different resonant frequencies for increasing a bandwidth of the smart antenna. Dielectric layers having different dielectric constants may also be used for coating the passive antenna elements for defining different resonant frequencies. Impedance elements are connected to the ground plane and are selectively connectable to the passive antenna elements for antenna beam steering.
