Intelligent multi-mode wireless power transmitter system
First Claim
1. A device for wirelessly transferring charging or operating power to a load coupled to a power receiving device, comprising:
- a processor configured to identify the power receiving device and to determine a range configuration relative to the power receiving device;
a first antenna comprising a dielectric surrounding a coiled conductor configured to emit a propagating radiation at a selected frequency and in a selected direction;
a first power transmitting circuit having a ground terminal and configured to provide a power signal at the selected frequency to the first antenna when the processor identifies the power receiving device within a far field configuration from the device; and
a plate configured to couple the ground terminal of the first power transmitting circuit with the first antenna and comprising a planar surface substantially parallel to the first antenna and at least an extension from the planar surface angled in a direction of the propagating radiation.

Abstract
A device including a processor configured to identify a power receiving device and to determine a range configuration relative to the power receiving device is provided. The device also includes a first antenna configured to emit a propagating radiation at a selected frequency and in a selected direction, and a first power transmitting circuit configured to provide a signal at the selected frequency to the first antenna when the processor identifies the power receiving device within a far field configuration from the device. The device also includes a plate, configured to couple a ground terminal of the first power transmitting circuit with the first antenna and including a planar surface and at least an extension angled in a direction of increased directivity of the propagating radiation. Methods for fabricating and using a device as above are also provided.
