| 1. A smart antenna comprising:
a dielectric substrate;
an active antenna element carried by said dielectric substrate and coplanar therewith, said active antenna element having
a T-shape;
at least one passive antenna element carried by said dielectric substrate and coplanar therewith, said at least one passive
antenna element comprising an inverted L-shaped portion laterally adjacent said active antenna element;
at least one impedance element selectively connectable to said at least one passive antenna element for antenna beam steering;
and
at least one switch carried by said dielectric substrate for selectively connecting said at least one passive antenna element
to said at least one impedance element.
