Distributed Microwave Wireless Power Transfer with Backscatter Feedback
2021 IEEE Wireless Power Transfer Conference (WPTC), 2021In 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.

Enhancement of received power in far-field microwave wireless power transfer
2020 IEEE Wireless Power Transfer Conference (WPTC), 2020A parabolic dish reflector (PDR) is designed and fabricated to convert the plane wave to spherical wave at the focus. The performance of PDR made from aluminum and Polydimethylsiloxane (PDMS) coated with aluminum is carried out. It is observed that the performance of the PDR made from PDMS is same as that made from aluminum, thus the proposed PDR made ...

Wireless power beam device using microwave power transfer
2014 IEEE Wireless Power Transfer Conference, 2014The authors proposed a novel WPT system using ceramic dielectric resonators. Unloaded Q of ceramic resonator is several tens of thousands depending on the material. Thus, we can expect much longer transmission distance by using ceramic resonator. It was confirmed that the power transfer of this system was conducted by a combination both of coupling in ...
