  • Patent number: 11476714
    Abstract: Systems and methods are described herein for providing wireless power to a mobile device, such as an aerial mobile device like an unmanned aerial vehicle (UAV). A navigational constraint model may prescribe a navigation path along which a wireless power transmission system can provide wireless power to the mobile device. Deviations from the prescribed path may require the mobile device to self-power. The prescription of a navigation path allows for the use of reduced-complexity wireless power transmitters that are fully capable of servicing the prescribed path. Multiple embodiments of prescribed paths with various limitations and features are set forth herein, along with multiple embodiments of wireless power transmission systems of reduced complexity and functionality to fully service the various embodiments of prescribed paths.

  • Patent number: 11355841
    Abstract: An embodiment of an antenna configured to form a high-power beam, such as a battery-charging beam, includes a transmission structure, signal couplers, amplifiers, and antenna elements. The transmission structure (e.g., a waveguide) is configured to carry a reference signal (e.g., a traveling reference wave), and each of the signal couplers is configured to generate a respective intermediate signal in response to the reference signal at a respective location along the transmission structure. Each of the amplifiers is configured to amplify, selectively, an intermediate signal from a respective one of the couplers, and each of the antenna elements (e.g., conductive patches) is configured to radiate a respective elemental signal in response to an amplified intermediate signal from a respective one of the amplifiers. In operation, the elemental signals interfere with one another to form a transmission beam, such as a battery-charging, or other high-power, transmission beam.

  • Patent number: 11271300
    Abstract: An embodiment of an antenna array includes a cavity, signal couplers, and antenna elements. The cavity is configured to reinforce a reference signal (e.g., a standing reference wave) having a wavelength ?, and each of the signal couplers is configured to generate a respective intermediate signal in response to the reference signal at a respective location of the cavity. And each of the antenna elements (e.g., conductive patches) is configured to radiate a respective elemental signal in response to an intermediate signal from a respective one of the signal couplers. In operation, the elemental signals interfere with one another to form a transmission beam. Controlling the cavity to introduce phase differences between the antenna elements can allow a wider pitch between adjacent antenna elements without the need for large, costly phase shifters, where the pitch can approach its theoretical limit of approximately ?/2.

  • Patent number: 11183887
    Abstract: System and methods are described herein for providing wireless power to a target device, such as a laptop computer, a mobile phone, a vehicle, robot, or an unmanned aerial vehicle or system (UAV) or (UAS). A tunable multi-element transmitter may transmit electromagnetic radiation (EMR) to the target device using any of a wide variety of frequency bands. A location determination subsystem and/or range determination subsystem may determine a relative location, orientation, and/or rotation of the target device. For a target device within a distance range for which a smallest achievable waist of the Gaussian beam of the EMR at an operational frequency is smaller than the multi-element EMR receiver of the target device, a non-Gaussian beamform may be determined to increase efficiency, decrease overheating, reduce spillover, increase total power output of rectenna receivers on the target device, or achieve another target power delivery goal.

  • Patent number: 10249950
    Abstract: In some embodiments, an antenna system includes antenna elements for transmitting and/or receiving electromagnetic radiation. The antenna elements may be connected to a feed via a plurality of tunable impedance elements. At least some of the tunable impedance elements may have nonlinear responses to impedance tuning that can be numerically approximated by nonlinear impedance-tuning parameter curves with a cumulative number of selectable nonlinear coefficients. Control inputs to nonlinearly vary impedance values of the tunable impedance elements allow for the selection of distinct impedance patterns that correspond to distinct field patterns attainable by the antenna system. The number of field patterns attainable is a function of the number of control inputs and a cumulative number of selectable nonlinear coefficients. Thus, a selection of tunable impedance elements and control inputs may be made to attain a target number of field patterns to serve a desired coverage area.
