Abstract
An inherently tuned antenna has a circuit for harvesting energy transmitted in space and includes portions that are structured to provide regenerative feedback into the antenna to produce an inherently tuned antenna which has an effective area substantially greater than its physical area. The inherently tuned antenna includes inherent distributive inductive, inherent distributive capacitive and inherent distributive resistive elements which cause the antenna to resonate responsive to receipt of energy at a particular frequency and to provide feedback to regenerate the antenna. The circuit may be provided on an integrated circuit chip. An associated method is provided.

40. A method of energy harvesting comprising
providing an inherently tuned antenna, and providing at least portions of said antenna structured to provide regenerative feedback into said antenna such that said inherently tuned antenna will have an effective area substantially greater than its physical area, employing in said circuit inherent distributed inductance and inherent distributed capacitance to form a tank circuit, delivering energy to said inherently tuned antenna through space, and providing a portion of the energy output of said inherently tuned antenna as regenerative feedback to said inherently tuned antenna to thereby establish in said antenna said effective area substantially greater than said physical area.
