Fast Transmit-Phase Optimization and Tracking to Moving Target in Distributed-Antenna Wireless Energy Transfer
A fast transmit-phase optimization scheme is described for a moving target in wireless energy transfer (WET) with distributed antennas. A transmit-phase inversion technique is sequentially applied to subset antennas used for dedicated energy beamforming (DEB). The received signal phase of each subset transmit antenna is estimated at a receiver and then fed back to a WET transmit-phase control unit. Our simulation results demonstrated that our proposed DEB-WET scheme with frame length of 50 ms was able to track the channel phase variations induced a maximum speed of 2.0 m/s and maintained high wireless power transfer efficiency.
