Abstract

Various embodiments of the present technology generally relate to wireless power transmitter and antenna configurations for transmitting wireless power to one or more clients. In some embodiments, the wireless power transmitter includes boards having multiple antennas (i.e., an Antenna Matrix Board(s) (AMB)). The antennas can be on one side of each AMB board, while the control and power circuitry are on the reverse side. The antennas emit electromagnetic (EM) radiant energy that the client(s) receive, store, and/or use for communication with the charger or for the client device battery charging process. The antenna boards can be arranged in a configuration to increase (e.g., optimize) the amount of power transmitted to client(s). In various embodiments, the boards are arranged in polygonal shape as individual flat panels physically coupled to a support structure and attached to the CCB by plug in multiple pin connectors unique in mechanical design.

Claims

1. A wireless power transmitter, comprising:

a group of antenna module boards (AMBs) including a set of antennas positioned on a first side of the AMBs,

wherein the group of AMBs are mechanically coupled to create a board-to-board connection;

wherein the set of antennas are dual port antennas that can drive multiple polarizations; and

a central controller board mechanically connected to the group of AMBs on a second side that is opposite the first side,

wherein the central controller board is configured to control power transmission from the set of antennas.

2. The wireless power transmitter of claim 1, wherein the group of AMBs is a first group of four AMBs and the wireless power transmitter further comprising additional groups of AMBs each having an additional central controller board, and wherein the central controller boards are daisy chained to the first group in a master-slave configuration.

3. The wireless power transmitter of claim 1, wherein the group of AMBs is a first group and the wireless power transmitter further comprises additional groups of AMBs each having an additional central controller broad, and wherein the central controller boards are daisy chained to the first group in a master-slave configuration.

4. The wireless power transmitter of claim 1, wherein the AMBs are arranged in a substantially flat design.

5. The wireless power transmitter of claim 4, wherein the substantially flat design is a square tile.

6. The wireless power transmitter of claim 5, wherein the square tile is formed into a twenty-four inch by twenty-four inch ceiling tile or a piece of art.

7. The wireless power transmitter of claim 1, further comprising shielded high-speed bus connections on at least one of the group of AMBs.

8. The wireless power transmitter of claim 1, wherein the central controller board includes an embedded proxy for secure communications with external Wi-Fi routers, secure power transmissions, and secure cloud-based data storage.

9. The wireless power transmitter of claim 1, includes a cylindrical housing or a tile housing composed of material that is partially transparent to radio frequency (RF) waves and partially perforated.

10. The wireless power transmitter of claim 1, wherein multiple polarizations of the set of antennas include circular polarizations or a vertical polarization and a horizontal polarization.

11. The wireless power transmitter of claim 1, wherein the central controller board also supports data transmissions using the set of antennas and the wireless power transmitter includes no fans for cooling.

12. The wireless power transmitter of claim 1, wherein at least one AMB in the group of AMBs is rotated one hundred and eighty degrees from an orientation of another AMB in the group of AMBs.

13. A wireless power transmitter, comprising:

a group of antenna module boards (AMBs), wherein each AMB in the group of AMBs includes a set of antennas,

wherein the group of AMBs are coupled to create a board-to-board connection;

wherein the sets of antennas on the group of AMBs include multi-port antennas that can drive multiple polarizations;

wherein at least some of the AMBs in the group of AMBs are positioned so that the multi-port antennas of one AMB are rotated from an orientation of another AMB in the group of AMBs; and

a central controller board connected to the group of AMBs,

wherein the central controller board is configured to control power transmission from the sets of antennas on the group of AMBs.

14. The wireless power transmitter of claim 13, wherein the group of AMBs is a first group of four AMBs and the wireless power transmitter further comprises additional groups of AMBs each having an additional central controller board, and wherein the central controller boards are daisy chained in a master-slave configuration.

15. The wireless power transmitter of claim 13, wherein the AMBs are arranged in a substantially flat design to create a tile.

16. The wireless power transmitter of claim 15, wherein the tile is a twenty-four inch by twenty-four inch ceiling tile or a piece of art.

17. The wireless power transmitter of claim 13, further comprising a shielded high-speed bus connection on at least one of the AMBs and wherein the central controller board includes an embedded proxy for secure communications with external Wi-Fi routers, secure power transmissions, and secure cloud-based data storage.

18. The wireless power transmitter of claim 13, includes a cylindrical housing or a tile housing composed of material that is partially transparent to radio frequency (RF) waves and partially perforated.

19. The wireless power transmitter of claim 13, wherein multiple polarizations of the set of antennas include a vertical polarization and a horizontal polarization.

20. The wireless power transmitter of claim 13, wherein the central controller board also supports data transmissions using the set of antennas.
