Wireless power receiver clients with dynamically reconfigurable antenna configurations
First Claim
1. A wireless power receiver apparatus comprising:
- one or more radio frequency (RF) antennas;
power metering circuitry adapted to measure at least one characteristic of retrodirective wireless power received from a wireless power transmission system in a multipath environment; and
control circuitry adapted to;
monitor the power metering circuitry to determine when a measure of the at least one characteristic of the wireless power fails to meet a preset threshold; and
dynamically reconfigure an antenna configuration of the wireless power receiver apparatus when the at least one characteristic of the wireless power fails to meet the preset threshold,wherein reconfiguring the antenna configuration comprises adjusting a position of an antenna radiation and reception pattern in three-dimensional space relative to a client device in which the wireless power receiver apparatus is embedded or otherwise associated.

Abstract
The technology described herein relates to wireless power receivers with reconfigurable (or adaptive) antenna configurations for improved wireless power transfer in multipath wireless power delivery environments. In an implementation, a wireless power receiver is described. The wireless power receiver includes one or more radio frequency (RF) antennas, power metering circuitry and control circuitry. The power metering circuitry is adapted to measure at least one characteristic of wireless power received from a wireless power transmission system in a multipath environment. The control circuitry is adapted to monitor the power metering circuitry to determine when the measure of the at least one characteristic of the wireless power fails to meet a preset threshold, and dynamically reconfigure an antenna configuration of the wireless power receiver when the at least one characteristic of the wireless power fails to meet the preset threshold.
