IACSIT International Journal of Engineering and Technology, Vol. 4, No. 1, February 2012 Design a Prototype of Wireless Power Transmission System Using RF/Microwave and Performance Analysis of Implementation Md M. Biswas, Member, IACSIT, Umama Zobayer, Md J. Hossain, Md Ashiquzzaman, and Md Saleh directive array configuration would have the potential of Abstract—A prototype of wireless power transmission (WPT) concentrated and directed microwave beam that can provide system has been designed in small scale which can be used to higher efficiency for longer distances. drive portable electronic devices. For power transmitting The objective of this work is to design a power purpose RF/microwave has been used. A detail discussion on transmission system through wireless medium in small scale transmitting and receiving antenna of WPT system has been presented. The step by step design method has been used in so that the power received from the receiver can be utilized to designing the entire system. Then, a simple practical approach drive portable electronic devices which require very low has been demonstrated. The detail performance on the practical power to operate. Practical difficulties to implement a implementation of wireless power transmission system has been prototype have also been analyzed. analyzed. The 4GHz designed system provides 2W receiving This research paper is organized as follows. A brief power w
