摘要：

This work targets microwave power transfer to a flying drone. The rf transmitter is assumed to use a magnetron unit array. Each magnetron transmitter is attached to large aperture antennas. Beam steering is provided by phased-array systems or mechanical gimbals on each antenna. The beams generated by the phase-controlled magnetrons and radiated from the transmitters are combined in free space. This report discusses the 5.8 GHz phase-locked magnetron characteristics. 60 % dc-rf conversion efficiency and 1 kW output are confirmed in a demonstration if self-excited oscillation. The phase-locked magnetron demonstration also confirms phase shifting of the output signal by controlling the phase of the injection signal.
