Abstract

Recent studies display that wi-fi charging is feasible the use of RF (radio frequency) sign and transmits the strength thru the air to rate the digital devices. Wireless charging is the first-rate and opportunity manner to the traditional charging system.

From last few years we absorbed the inductive wireless charging but now is the time to go one step towards Wireless charging using RF (radio frequency) signal that is discussed in this chapter. The analysis seeks to use the RF received by its antenna to recharge mobile devices. The frequency of the RF signal is selected on the basis of Environment where exactly our application is going to be implemented (Eg. Wifi environment, GSM environment etc) and the selection of the antenna is based on the power density and directionality. The multistage boosting circuit is used to harvest 3.7V DC output from RF signals which is the required voltage to charge mobile and others micro devices. In this chapter we will be discussing fundamentals of RF transmission along with the detail review on different researches conducted.
