Abstract
A multi-state variable dielectric antenna, comprising: a top dielectric; a bottom dielectric; a variable dielectric plate between the top dielectric and the bottom dielectric; a plurality of conductive devices provided over the variable dielectric plate; an RF feed provided below the bottom dielectric; wherein the variable dielectric plate comprises: a top binder; a bottom binder; variable dielectric constant material provided between the top binder and bottom binder, the variable dielectric constant material divided into pixels, each pixel located below a corresponding conductive device and having a plurality of electrodes; a plurality of conductive lines, each conductive line connected independently to one of the electrodes and to a controller, such that each of the plurality of electrodes of a single pixel independently receives an activation signal from the controller.
