1. A transmitter system for wireless power, comprising:

  • means for generating a wireless field for charging a device that includes a receiving antenna, the receiving antenna resonant at a first frequency;

    means for generating a signal at said first frequency, said signal generating means also configured to provide the signal to the wireless field generating means;

    means for detecting coupling of said wireless field generating means with the receiving antenna when the wireless field generating means is at a first alignment position relative to the receiving antenna; and

    means for adjusting an x-y alignment of the wireless field generating means, from the first alignment position to a second alignment position relative to the receiving antenna, based on detected coupling to improve said coupling.
