Title:
BROADBAND SMART ANTENNA AND ASSOCIATED METHODS
Document Type and Number:
WIPO Patent Application WO2006015215
Kind Code:
A9
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.
