摘要：
This paper presents a scheme for designing a kind of wireless charging system aimed to provide power transmission for personal mobile devices such as cell phone. This scheme consists of three parts: wireless power transmission design, wireless signal transmission design and charging manage design. A circular array consisting of some antenna elements is employed in the scheme as transmit access of power and signal. In the supposed indoor condition, the transfer efficiency can up to 66%. The charging manage. adopt a. close-loop optimal charging, charging time can be reduced by 30%, and the battery' s life can be lengthened by 20%.
