Techniques for delivering retrodirective wireless power
First Claim
1. A wireless power transmission system, comprising:
- an adaptively-phased antenna array having multiple transceivers;
control circuitry configured to;
identify one or more receive characteristics of a calibration signal at multiple transceivers, wherein the calibration signal is transmitted by one or more transceivers of a client device in a multipath wireless power delivery environment; and
determine one or more wireless power transmit characteristics for the multiple transceivers based on the one or more receive characteristics,wherein the wireless power transmit characteristics identify a configuration for transmitting wireless power signals over multiple paths that constructively interfere in a three-dimensional client radiation and reception pattern space proximate to the client device.

Abstract
Techniques are described herein for delivering retrodirective wireless radio frequency (RF) power to a client device in a wireless power delivery environment. More specifically, embodiments of the present disclosure describe techniques for delivering directed wireless RF power to a client device in a wireless power delivery environment via multiple wireless power signals over multiple wireless power delivery paths. The client device includes one or more RF client transceivers that collectively have a radiation and reception pattern in a three-dimensional space proximate to the client device. The techniques identify the wireless power delivery paths over which wireless power signals can be delivered and deliver the wireless power in a manner that matches the client radiation and reception pattern in the three-dimensional space proximate to the client device.
