Wireless energy transfer in a far-field environment

An antenna controller, comprising:

• an antenna actuator;
• a processor device;
• and
• a non-transitory computer-readable medium having instructions stored thereon that are executable by the processor device for performing operations, the operations comprising:
• receiving position information about a mobile device from a location system;
• receiving motion and direction information about the mobile device from an inertial navigation system associated with the mobile device;
• receiving height information about the mobile device from an inertial measurement unit associated with the mobile device;
• determining a predicted position of the mobile device using the position information, the motion and direction information, and the height information;
• and
• outputting a command to the antenna actuator to change a position of an antenna element based on the predicted position of the mobile device,
• wherein the antenna actuator is configured to control the position of the antenna element in response to receiving the command to wirelessly transmit a beam of a power signal for charging a power source associated with the mobile device, the antenna element having different types of metamaterials thereon for transmitting the beam.

A method, comprising:

• in response to receiving a request from a mobile device to wirelessly transmit a beam of a power signal to charge a power source associated with the mobile device:
• receiving position information about the mobile device from a location system;
• receiving motion and direction information about the mobile device from an inertial navigation system associated with the mobile device;
• receiving height information about the mobile device from an inertial measurement unit associated with the mobile device;
• determining, by an antenna controller, a predicted position of the mobile device using the position information, the motion and direction information, and the height information;
• controlling a position of an antenna element based on the predicted position;
• and
• wirelessly transmitting, by the antenna element having different types of metamaterials thereon, the beam to the mobile device.
