Abstract: Techniques and apparatus are described for use in far-field wireless power transmitter. A far-field wireless power transmitter uses beamforming to localize a power signal transmitted from an array of antenna. A multi-tone signal is used for the power signal, where the signal transmitted from each of the antenna is formed of a plurality of tones having a frequency center and separated by a uniform frequency difference, and relative delays and/or relative amplitude differences are introduced into the signals from the different antennas of the array so that a beam is formed in a region where a far-field wireless power receiver's antenna is located. By use of two such transmitters placed to either side of the receiver, a hot-spot for the multi-tone power signal can be formed in the region of the receiver's antenna, with lower field values away from the region.
