Patent Images
1. A system for wireless power transmission to an electronic receiver placed in the vicinity of the system, the system comprising:
- a power transmitter having a resonance frequency; and
at least one power repeater tuned to a resonance frequency substantially different than the resonance frequency of the power transmitter,wherein the at least one power repeater is coupled to the power transmitter and is configured to repeat power from the power transmitter to the power receiver, andwherein an operating frequency of the power transmitter is slightly higher than the resonance frequency of the repeater.

Abstract
A system for wireless power transmission to an electronic receiver placed in the vicinity of the system comprises a power transmitter and at least one power repeater coupled to the power transmitter. The power repeater is configured to repeat power between the power transmitter and the receiver, wherein the power repeater is tunable to a predetermined frequency, and wherein the power repeater is configured to allow operation at a frequency substantially equal to the frequency of the power transmitter.
