Abstract
A novel method for transferring electrical power wirelessly in order to charge various low power consumption appliances is presented. In practice, a variable power and wideband Agilent N5182A transmitter and an RF electronic receiver were configured in such manner to examine and to demonstrate the constructed WPT system. The RF-circuit part of the receiver consisted of the antenna system, RF-signal processing and converter, DC-operational amplifier and the electronic load. The distance separation between the transmitter and the receiver was varied to measure the transmission performance. Several critical factors influence the performance of WPT design such as the strength of transmitter power, moving objects surrounding the receiver, the absorbed obstacle existed, and the pointing angle of the energy illumination were also investigated.
