  • Publication number: 20240079910
    Abstract: An example near-field charging system includes a housing that includes a charging surface and at least one other surface, a radiating antenna, and a non-radiating element positioned above the radiating antenna within the housing such that the non-radiating element is closer to the charging surface than the radiating antenna. The radiating antenna produces a first electromagnetic-field distribution that is received by a receiver, the first electromagnetic-field provides usable power when the receiver is placed at any position on a first portion of the charging surface. The non-radiating element changes a distribution characteristic of the first electromagnetic-field distribution to produce a second electromagnetic-field distribution, the second electromagnetic-field distribution providing usable power to the receiver when the receiver is placed at any position across a second portion of the charging surface of the housing, and the second portion is at least 10% percent greater than the first portion.

  • Publication number: 20230291094
    Abstract: An example method performed by a wireless-power-transmitting device including an antenna array is provided. The method includes, based on a location of the wireless-power-receiving device, selecting a first value for a first transmission characteristic that is used for transmission of electromagnetic waves by a first antenna group, and a second value, distinct from the first value, for the first transmission characteristic that is used for transmission of electromagnetic waves by a second antenna group. The method also includes transmitting to the location of the wireless-power-receiving device, by the first antenna group, first electromagnetic waves with the first value for the first transmission characteristic, and transmitting to a focal point that is further from the wireless-power-transmitting device than the location of the wireless-power-receiving device, by the second antenna group, second electromagnetic waves with the second value for the first transmission characteristic.

  • Patent number: 11699847
    Abstract: An example method performed by a wireless-power-transmitting device that includes an antenna array is provided. The method includes radiating electromagnetic waves that form a maximum power level at a first distance away from the antenna array. Moreover, a power level of the radiated electromagnetic waves decreases, relative to the maximum power level, by at least a predefined amount at a predefined radial distance away from the maximum power level. In some embodiments, the method also includes detecting a location of a wireless-power-receiving device, whereby the location of the wireless-power-receiving device is further from the antenna array than a location of the maximum power level.

  • Publication number: 20220255360
    Abstract: An example transmitter comprises a housing with a top surface that allows for placement of a ring device to be wirelessly charged by the transmitter, the ring device is a device that is capable of receiving a power from the transmitter. An antenna, placed inside of the housing and disposed below the top surface, configured to transmit radio frequency (“RF”) waves to the ring device, where a radiator of the antenna has a circular shape that is positioned coplanar with the inner surface of the housing and the radiator has a certain thickness that is defined by an inner radiator diameter and an outer radiator diameter; and the inner radiator diameter of the radiator is substantially equal to the first inner ring diameter of the smallest ring device, and the outer radiator diameter of the radiator is substantially equal to the first outer ring diameter of the largest ring device.
