Abstract :
In this paper, design procedure and characteristics of an RF energy harvesting circuit based on single-stage voltage multiplier rectifier have been discussed and analyzed. This circuit is capable to recycle RF energy at 2.45 GHz, and by connecting to a 2.45 GHz antenna, it is possible to form a complete rectenna device. The values of output dc voltage and power according to the received RF power have been measured and the best value of load resistance to harvest maximum output dc power has been selected by simulation.
