Design of an Efficient Rectifier Circuit for RF Energy Harvesting System

An efficient rectifier system along with an impedance matching network is proposed in this article. Impedance matching network is designed using two microstrip lines. Rectifier system for better RF to DC conversion is designed using a bridge rectifier. The proposed rectifier system provides a maximum efficiency of 50%. The impedance matching network improves the overall system performances significantly. The circuit simulator ADS 2015 is used for this system design. Performances of the proposed system are analysed using simulation results only. This proposed rectifier system along with the impedance matching network can be useful for the design of an efficient RF energy harvesting system.
