1. A phase shifting device comprising:

  • a substrate; and

    a plurality of phase shifters on said substrate, each phase shifter comprising a first conductive portion above said substrate and defining a signal path, and a body above said signal path and comprising a phase shifting material having a controllable dielectric constant for causing a phase shift of a signal being conducted through said signal path;

    all respective bodies of adjacent phase shifters being laterally spaced apart from one another.
