Abstract
A wireless untethered device which may be an integrated circuit chip or printed circuit board having at least one integrated antenna and circuitry operatively associated with the antenna for receipt of energy harvested from space by the antenna. The antenna has an effective area greater than its physical area. A system which receives power from the harvested energy after the energy is processed by the circuitry may also be provided with mismatched impedance between the antenna and a circuit resistance.
