In response to the detecting, the method includes: determining whether the receiver has been placed on the pad. In accordance with determining that the receiver has been placed on the pad, the method includes: selectively transmitting, by respective antenna elements included in a plurality of antenna zones of the pad, respective test power transmission signals with a first set of transmission characteristics until a determination is made that a particular power-delivery parameter associated with transmission of a respective test power transmission signal by at least one particular antenna zone satisfies power-delivery criteria. Upon determining that the particular power-delivery parameter satisfies the power-delivery criteria, the method also includes: transmitting additional power transmission signals to the receiver using the at least one particular antenna zone."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Methods of selectively activating antenna zones of a near-field charging pad to maximize wireless power delivered to a receiver","description":"An example method includes detecting, via a wireless communication component of a near-field charging pad (pad), that a receiver is within a threshold distance of the pad.
