Abstract: With the wireless communication advances in the recent years, the level of RF energy present in the environment rises day by day. Only fractional part of RF energy presented is used, on contra, the remaining RF energy is the wastage in the form of waves that become challenging issue to harvest. Here, one of the RF harvesting systems known as Rectenna is implemented. Star shaped Dielectric Resonator Antenna (DRA) is used as receiver to collect RF energy at ISM frequency band (2.45 GHz) from atmosphere. The received RF energy is fed to Full wave rectifier circuit. The parametric study shows the 24.733 dBm power is harvested for 30 dBm input power is fed. The maximum 81.67 % RF to DC conversion efficiency is achieved.
