Integration of Localization and Wireless Power Transfer Using Microwave
2021This paper proposes a system to realize simultaneous power supply and localization for indoor Internet of Things (IoT) devices. The power supply to IoT devices is realized via microwave power transfer using numerous distributed access points (APs). The proposed system realizes efficient power transmission by controlling the phase of microwaves from ...

Power transfer characteristics of a microwave reverberation chamber
IEEE Transactions on Electromagnetic Compatibility, 1996Power transfer through a microwave reverberation chamber is studied theoretically and experimentally. Two configurations are employed as follows. In the first, the chamber contains a transmitting antenna and a receiving antenna; in the second, it contains a transmitting antenna and a receiving D-dot sensor. For each configuration a theoretical model is

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 ...

Wireless Power Transfer Using Microwaves
2017In this paper, a model has been presented which transfers electric power without wires by using microwaves. A breadboard model of receiving antenna called rectenna is developed for preliminary experiments including wireless power transmission. The paper presents one to one MPT system in which electric power is transferred at radio frequencies ranging ...

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 ...

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.
