Abstract
An antenna includes a dielectric substrate, an ative antenna element carried by the dielectric substrate, and passive antenna elements carried by the dielectric substrate. The passive antenna elements are laterally adjacent the active antenna element. A respective impedance element is selectively connectable to each passive antenna element for antenna beam steering. Image elements are carried by the dielectric substrate, and a respective image element is connected to each impedance element and ground.
