Abstract: According to various embodiments, systems and methods for wirelessly transmitting energy to a moving wireless power receiver in a network of interlinked prescribed paths. A position of a wireless power receiver in a network of interlinked prescribed paths is tracked as the wireless power receiver traverses one or more prescribed paths in the network of interlinked prescribed paths. Energy is wirelessly transmitted from one or more wireless power transmitters to the wireless power receiver based on the position of the wireless power receiver in the network of interlinked prescribed paths. Specifically, the energy is wirelessly transmitted to the wireless power receiver based on the position of the wireless power receiver in the network of interlinked prescribed paths as the wireless power receiver traverses the one or more prescribed paths in the network of interlinked prescribed paths.

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.

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.

Abstract: An antenna system includes a tunable medium, rectifier circuitry, combining circuitry, and control circuitry. The tunable medium includes antenna elements corresponding to lumped impedance elements and variable impedance control inputs configured to enable selection of an impedance value for each of the lumped impedance elements. The control circuitry is configured to determine a scattering matrix (S-matrix) relating field amplitudes at lumped ports including internal lumped ports and lumped external ports. The internal lumped ports correspond to the lumped impedance elements, and the lumped external ports correspond to at least one of the rectifier circuitry inputs, the combined output of the combining circuitry, and the at least one transmitting element. A method includes determining at least a portion of component values of a desired S-matrix, and adjusting the variable impedance control inputs to at least approximate at least a portion of the desired S-matrix.

Abstract: The present technology pertains to a system and method of operation of a metamaterial phase shifter having various use applications. In one aspect of the present disclosure, a phase shifter includes a network of tunable impedance elements and a controller. The controller is coupled to the network of tunable impedance elements and configured to receive a phase shift input value and determine a corresponding tuning voltage to be supplied to each tunable impedance element of the network of tunable impedance elements based on the phase shift input value, the network of tunable impedance element being configured to shift a phase of an input signal based on tuning voltages supplied to the network of tunable impedance elements by the controller.

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 λ, 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 λ/2.

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.

Abstract: According to various embodiments, a moving wireless power receiver is configured to receive power wirelessly based on a prescribed path of the wireless power receiver. A prescribed path that a moving wireless power receiver traverses is identified. Further, at least one element of the wireless power receiver is controlled based on the prescribed path to change an amount of power received at the wireless power receiver from incident power transmitted by one or more wireless power transmitters. Specifically, the at least one element can be controlled to change the amount of power received at the wireless power receiver as either or both a posture and a position of the wireless power receiver change with respect to the one or more wireless power transmitters as the wireless power receiver traverses the prescribed path.
