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.

This paper presents a broadband hybrid slot-dielectric resonator antenna for radiofrequency (RF) energy-harvesting application. The antenna geometry consists of a simple pentagon-shaped dielectric resonator antenna (PDRA) excited by a microstrip feed underlying rectangular slot with narrow notch. It is investigated that the bandwidth of the proposed PDRA is improved significantly owing to electromagnetic coupling between feeding slot and the dielectric resonator. The measured results demonstrate that the proposed PDRA achieves an impedance bandwidth of 110.8%, covering the frequency range from 0.86 to 3 GHz in addition of stable radiation pattern with peak gain of 6.8 dBi and more than 90% radiation efficiency throughout the band, showing its suitability for RF energy harvesting application. For this to be feasible, the developed antenna is matched with the rectifier at two public telecommunication bands of GSM-900 and GSM-1800 using a compact dual-band hybrid matching network. The measured result demonstrates that the proposed dual-band rectenna system provides the peak efficiency of 63 and 59% for a load impedance of 4.7 kΩ at 0.9 and 1.8 GHz, respectively.

A dual frequency Dielectric Resonator antenna for wireless communication applications in the S and C bands with an operating frequency of 2.65GHz and 4.62GHz is presented. The patch is a dielectric material with a high dielectric constant value of 20. A 50Ω strip line is considered as feed and is coupled to the dielectric radiator via the rectangular slot etched in ground plane. The slot etched in ground plane is made so as to facilitate the power form the feed line to the radiator. The overall dimension of the antenna is 100mm×35mm×0.8mm. A dual frequency antenna has been proposed which will be operational at the frequencies of 2.65GHz and 4.62GHz with a gain of 4.42dB and 7.78dB respectively. Low cost FR4 material is been used as the laminate base for the antenna which will act as the dielectric material.

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 .
