Receivers for wireless power transmission
First Claim
1. A radio frequency (RF) receiver for receiving RF wireless power signals, comprising:
- a plurality of RF antenna/rectifier sets each comprising;
a plurality of RF antenna elements configured to receive RF power waves from a remote power transmitter; and
only one RF rectifier connected to the plurality of RF antenna elements, the RF rectifier configured to rectify alternating current (AC) generated by the plurality of RF antenna elements to direct current (DC) voltage;
a single DC power converter connected to the plurality of RF antenna/rectifier sets, the single DC power converter configured to regulate the DC voltage for powering a portable electronic device or charging a battery coupled with the portable electronic device; and
a communications component configured to generate a communication RF signal identifying a tracking location of the RF receiver with respect to the remote power transmitter, wherein the remote power transmitter is configured to generate and transmit the RF power waves controlled through phase and relative amplitude to form constructive interference patterns of energy aimed at the tracking location for powering the portable electronic device or for charging the battery.
