Abstract
A radio-frequency power transmitter. The radio-frequency power transmitter includes an array of patch antennas, an array of phase modulators, each phase modulator having an input port and associated with one or more of the patch antennas, a local oscillator that provides an oscillatory signal to the input port of each of the phase modulators, an array of amplifiers, each amplifier receiving an input from one of the phase modulators, and a microprocessor configured to interface with the array of phase modulators and control a holistic radiative power transmission vector pattern generated by the radio-frequency power transmitter.
