1. A wireless power transmitter, comprising:
- first antenna module boards (AMBs), wherein each of the first AMBs comprises;
a first set of antennas positioned on a first side of the first AMB; and
a first control circuit arranged on a second side of the first AMB opposite the first side,wherein the first control circuit is configured to control power transmission from the first set of antennas;
second AMBs, wherein each of the second AMBs comprises;
a second set of antennas positioned on a first side of the second AMB; and
a second control circuit arranged on a second side of the second AMB opposite the first side,wherein the second control circuit is configured to control transmission of power from the second set of antennas;
wherein the first and second AMBs are positioned in a multi-pointed star configuration,wherein the first and second sets of antennas are on an exterior of the star configuration, andwherein each of the first AMB is positioned to partially face one of the second AMBs.

Abstract
The disclosed technology relates to antenna configurations for wireless power transmission and supplemental visual signals. In some implementations, the disclosed technology includes a wireless power transmitter with boards that have multiple antennas physically coupled to the board. In some implementations, the antennas boards are arranged in a polygonal configuration (e.g., star shape). Additionally, in some implementations, the antennas can have different polarization configurations.
