1. A wireless power transmitter, comprising:
- a partially perforated cylindrical housing composed of material that is at least partially transparent to radio frequency (RF) waves;
first antenna module boards (AMBs), wherein each AMB of the first AMBs comprises;
a first set of antennas positioned on a first side; and
a first control circuit arranged on a second side 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 AMB of the second AMBs comprises;
a second set of antennas positioned on a first side; and
a second control circuit arranged on a second side 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 with the first and second sets of antennas situated on an exterior of the star configuration, and each of the first AMBs positioned to partially face one of the second AMBs; and
wherein the cylindrical housing is spaced apart from and peripheral to the star configuration.

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.
