摘要： Disclosed is a beamforming method for microwave power transmission. The beamforming method includes sending, by a transmitter, microwaves to each training slot based on a random phase through antennas, receiving from a receiver, by the transmitter, a power measurement value for each of the training slots, estimating, by the transmitter, a channel using the received power measurement value, and determining, by the transmitter, beamforming weight based on information about the estimated channel.

摘要： The embodiments described herein include a transmitter that transmits a power transmission signal (e.g., radio frequency (RF) signal waves) to create a three-dimensional pocket of energy. At least one receiver can be connected to or integrated into electronic devices and receive power from the pocket of energy. The transmitter can locate the at least one receiver in a three-dimensional space using a communication medium (e.g., Bluetooth technology). The transmitter generates a waveform to create a pocket of energy around each of the at least one receiver. The transmitter uses an algorithm to direct, focus, and control the waveform in three dimensions. The receiver can convert the transmission signals (e.g., RF signals) into electricity for powering an electronic device. Accordingly, the embodiments for wireless power transmission can allow powering and charging a plurality of electrical devices without wires.

摘要： An antenna arrangement for transmitting energy is described. The antenna arrangement includes a planar array of two or more rectangular loop antennas, adapted to transmit energy at low frequencies via non-radiative resonant coupling and at high frequencies via radiative coupling. The low frequencies correspond to a wavelength with half of the wavelength being larger than the longest rectangular loop antenna dimension and the high frequencies correspond to a wavelength with half of the wavelength being approximately equal the longest rectangular loop antenna dimension. The antenna arrangement also includes a feeding network connected to the planar array, which includes a phase shifting means for providing a phase difference between signals at the high frequencies to be transmitted by different rectangular loop antennas of the planar array, whereby the amount of phase difference is related to the distance of the rectangular loop antennas to a focal point in the near-field of the planar array. The antenna arrangement also includes means adapted for distributing the signals applied to the feeding network.

摘要： The present invention provides wireless charging techniques and devices for charging electronic device(s) within a closed space defined by a substantially hollow housing containing an antenna arrangement and configured to define an inner cavity for propagation of electromagnetic radiation from the antenna arrangement. The housing has an inner surface, encompassing the inner cavity, which geometry and material composition selected to define a general propagation path for the predetermined electromagnetic radiation from the antenna arrangement towards a charging zone. The inner cavity of the housing operates as a waveguide for directionally guiding the electromagnetic radiation to the charging zone and providing substantially maximal intensity of the electromagnetic radiation within the charging zone.

摘要： A wireless power supply device is capable of supplying constant power without fluctuation in transmission efficiency even when small-sized antennas in which the power fluctuates due to the transmission distance are used. The wireless power supply device includes a first power receiving antenna having a power receiving surface facing a power transmission surface of a first transmission antenna and a second power receiving antenna having a power receiving surface facing a power transmission surface of a second power transmission antenna, both are integrally formed and connected to a power supply target. A direction in which the power receiving surface of the first power receiving antenna faces the power transmission surface of the first power transmission antenna is parallel to a direction in which the power receiving surface of the second power receiving antenna faces the power transmission surface of the second power transmission antenna.

摘要： A system on a package (SOP) can include a galvanic isolator. The galvanic isolator can include an input stage configured to transmit an input RF signal in response to receiving an input modulated signal. The galvanic isolator can also include a resonant coupler electrically isolated from the input stage by a dielectric. The resonant coupler can be configured to filter the input RF signal and transmit an output RF signal in response to the input RF signal. The galvanic isolator can further include an output stage electrically isolated from the resonant coupler by the dielectric. The output stage can be configured to provide an output modulated signal in response to receiving the output RF signal.
