Abstract
An apparatus is disclosed for providing a radiating element having an electrical reflective phase shifter for reflecting electromagnetic energy received from an electromagnetic energy source including a dielectric substrate having a top surface, a conductive layer having a channel-like opening in its top surface and disposed on the top surface of the dielectric substrate, at least one electrostatic switch spans the channel-like opening and a means for selectively actuating the electrostatic switch to reflect the electrostatic energy. The electrostatically actuated mechanical switch utilizes a cantilever element fabricated by solid-state microfabrication techniques. The electrical reflective phase shifter can be grouped into a phase shifting reflect array for beam steering an electromagnetic energy from an electromagnetic energy source.
