Beschreibung
Zusammenfassung:	A module for use in a wireless power system, the module comprising: a resonator circuit comprising an inductive element formed by at least one loop of conductive material, the resonator circuit comprising additional circuitry electrically connected directly to the inductive element to couple power between the inductive element and an external circuit having an impedance Zo, wherein the inductive element forms a resonator with at least a portion of the additional circuitry , wherein the additional circuitry has two terminals for connecting to the external circuit, and wherein the external circuit comprises a power supply or a load, wherein the resonator is a high-Q resonator having an intrinsic Q greater than 100 for a resonant frequency f between 10 kHz and 100 MHz, and wherein the two terminals for connecting the additional circuitry to the external circuit are located at points that are electrically symmetric with respect to an axis defined by voltage-node points for the resonator.
