Recently, the various methods for RF energy harvesting and reutilizing has become the challenging matter around the world to minimize the wastage of RF energy in the form of electromagnetic waves within the atmosphere. An associate approach of collecting a particular range of frequencies & conversion into dc current- Rectenna is proposed here. Star shaped Dielectric Resonator Antenna is implemented as antenna for receiving RF energy at 2.44 GHz resonant frequency. It is observed that Star shaped DRA exhibits a radiated power of 0.8825 W with respect to 1W incident power and maximum gain of 5.9672 dBi. The RF power received by Antenna is given to a Rectifier circuit via proper impedance matching circuit. The rectified pulsating DC power is given to capacitor filter to suppress harmonics .
