摘要: 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.

摘要: 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.

摘要: 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.
