  • Patent number: 10381880
    Abstract: A plurality of integrated antenna structures described herein may be formed in a flat panel antenna arrays which may be arranged in equally spaced grid and may be used in transmitters for sending focused RF waves towards a receiver for wireless power charging or powering. Each of the integrated antenna structures may include planar inverted-F antennas (PIFAs) integrated with artificial magnetic conductor (AMC) metamaterials. As a result of their high directionality and form factor, the integrated antenna structures may be placed very close together, thus enabling the integration of a high number of integrated antenna structures in a single flat panel antenna array which may fit about 400+ integrated antenna structures. Each integrated antenna structure in the flat panel antenna arrays may be operated independently, thus enabling an enhanced control over the pocket forming. In addition, the higher number of integrated antenna structures may contribute to a higher gain for the flat panel antenna arrays.

  • Patent number: 10320446
    Abstract: Near-field power transfer systems can include antenna elements that constructed or printed close to each other in a meandered arrangement, where neighboring antenna elements conduct currents that flow in opposite directions. This current flow entirely or almost entirely cancels out any far field RF radiation generated by the antennas or otherwise generated by the electromagnetic effects of the current flow. For a first current flowing in a first path, there may be a second current flowing in a second cancellation path, which cancels the far field radiation produced by the first current flowing in the first path. Therefore, there may be no radiation of power to the far field. Such cancellation, may not occur in a near-field active zone, where the transfer of power may occur between the transmitter and the receiver. A ground plane may block the leakage of power from the back of a transmitter and/or a receiver.

  • Patent number: 10312715
    Abstract: Embodiments disclosed herein may generate and transmit power waves that, as result of their physical waveform characteristics (e.g., frequency, amplitude, phase, gain, direction), converge at a predetermined location in a transmission field to generate a pocket of energy. Receivers associated with an electronic device being powered by the wireless charging system, may extract energy from these pockets of energy and then convert that energy into usable electric power for the electronic device associated with a receiver. The pockets of energy may manifest as a three-dimensional field (e.g., transmission field) where energy may be harvested by a receiver positioned within or nearby the pocket of energy.
