In this research, we have develop a printed microstrip antenna which can be used for RF energy harvesting applications. For the simulation and validation purpose a 3D electromagnetic simulator HFSS tool has been used. The targeting frequency band of operations are GSM/3G/4G with VSWR(voltage standing wave ratio)<=2. Following the antenna design, a differential RF energy harvesting circuit, which comprises a matching circuit, rectifier (RF-DC conversion) and charging circuit has designed with good peak efficiency for the given load.
