Abstract
A charging pad for transmitting wireless power waves for charging an electronic device is disclosed. The charging pad includes transmitting antenna elements that are configured to be selectively activated to transmit wireless power waves to the electronic device for wireless charging. The charging pad includes a charging surface including a guiding contour that aligns a position of the electronic device on the charging surface such that a transmitting antenna element is within a predetermined distance of the electronic device and has a predetermined coupling efficiency. The charging pad further includes a transmitter controller integrated circuit (IC). The transmitter controller IC is configured to detect the position of the electronic device on the charging surface and selectively activate at least one transmitting antenna element based on a determination that the at least one transmitting antenna element is within the predetermined distance of the electronic device and has the predetermined coupling efficiency.
