Radio frequency (RF) energy transfer and harvesting techniques have recently become alternative methods to power the next generation wireless networks. The RF energy harvesting system was designed to convert the RF energy available in the atmosphere into useful electrical energy which can be used to charge a battery of capacity 50 uAh. This battery requires a voltage in the range of 4- 4.2V to get itself charged. In this paper we have designed and simulated a Radio Frequency (RF) energy harvesting circuit which utilized available RF energy with the voltage boosting circuit. Simulation results represents that by using matching network of high-Q, output voltage of harvesting circuit increases and it becomes more sensitive with respect to input signal frequency and value of elements used.
