1. An apparatus comprising:

  • an energy convertor for receiving electromagnetic energy and converting the electromagnetic energy into electrical current, said energy converter including;

    an antenna including a first grid array including a first grid pattern of diodes located substantially along a first surface, with the first grid array acting as a half-wave rectifying element when illuminated by the electromagnetic energy, and a second grid array including a second grid pattern of diodes located substantially along a second surface, with the second grid array acting as a half-wave rectifying element when illuminated by the electromagnetic energy, wherein the first surface is spaced from the second surface; and

    an electrical circuit connecting the first and second arrays to an electrical output whereby the electromagnetic energy impinging on the first and second grid arrays is converted into electrical current at an output, wherein the energy converter is configured such that at least one of;

    the first grid array is offset from the second grid array; and

    the first grid pattern of diodes has a different diode density from the second grid pattern of diodes.
