1. A programmable antenna comprises:

  • a substrate including at least one semi-conductor region;

    a plurality of metallic inclusions interspersed within the at least one semi-conductor region, wherein the plurality of metallic inclusions are, in a non-conductive state, not electrically coupled within the at least one semi-conductor region;

    a plurality of bidirectional coupling circuits supported by the substrate, wherein the plurality of bidirectional coupling circuits is physically distributed within the at least one semi-conductor region and is physically proximal to the plurality of metallic inclusions; and

    a control module operable to activate a set of bidirectional coupling circuits of the plurality of bidirectional coupling circuits, wherein, when the set of bidirectional coupling circuits is active, the set of bidirectional coupling circuits provides a conductive state where an electric field electrically couples a set of metallic inclusions of the plurality of metallic inclusions within the at least one semi-conductor region to collectively provide a conductive area within the region, wherein the conductive area provides an antenna.
