ABSTRACT:
A low profile smart antenna includes an active antenna element carried by a dielectric substrate, and active antenna element has a T-shape. Passive antenna elements are carried by the dielectric substrate, and they have an inverted L-shaped portion laterally adjacent the active antenna element. Impedance elements are selectively connectable to the passive antenna elements for antenna beam steering.
