In recent, microwave power transfer (MPT) for IoT devices has been studied. The distributed MPT can supply power efficiently by cooperate multiple transmit antenna arranged distributed in a relatively wide area. In this paper, we propose a method for distributed beam control by closed-loop with a backscatter signal from the receiver. The effectiveness of the proposed method will be demonstrated by lay-trace simulation and experiment.
