1. A method comprising:

  • positioning an antenna array beneath or on the road surface of a roadway, the antenna array configured to transmit RF signals responsive to RF processing logic and/or circuitry;

    coupling a rectenna array to an aircraft, the rectenna array configured to receive the RF signals transmitted from the antenna array and to generate power from the RF signals;

    providing feedback signals from the aircraft to the RF processing logic and/or circuitry, the feedback signals including channel state information (CSI) defining a current state of the channels between the antenna array and the rectenna array, the RF processing logic and/or circuitry using the channel state information to adjust the RF signal transmissions from the antenna array to improve the efficiency of the power generated by the rectenna array; and

    using the power generated by the rectenna array to power the aircraft.
