1. A device for wireless power transmission, including a system for supplying transponders, comprising:

  • at least one high-frequency transmitter that transmits a transmitted high-frequency output signal, and at least one high-frequency receiver that receives the transmitted high-frequency output signal, wherein the at least one high-frequency transmitter is connected to at least one antenna, and the at least one high-frequency receiver is connected to at least one antenna, wherein the receiver obtains its operating power from the transmitted high-frequency output signal from said transmitter, wherein (1) the transmitted high-frequency output signal from the transmitter is modulated with at least one converter clock suitable for a DC-DC converter, (2) the receiver has at least one detector for demodulating the at least one converter clock from the transmitted high frequency output signal, (3),the receiver generates a DC operating voltage for the DC-DC converter from the high-frequency output signal using at least one of a rectifier and the at least one detector, (4) the DC-DC converter, using the at least one converter clock, and generating another DC voltage to operate further circuit elements.
