Abstract
A structure for wireless communication having a plurality of conductor layers, an insulator layer separating each of the conductor layers, and at least one connector connecting two of the conductor layers wherein an electrical resistance is reduced when an electrical signal is induced in the resonator at a predetermined frequency. The structure is capable of transmitting or receiving electrical energy and/or data at various near and far field magnetic coupling frequencies.
