ABSTRACT: In this paper, we utilized villared rectifier technique to harvest wireless energy to
overcome previously used RF-WEH rectenna. Our design focuses mainly on a
multiple-stage Villard voltage multiplier model to rectify the output voltage
of the rectenna and transferred it to a dc load. As a starting point,
optimization and parameter analysis offer a novel and small antenna for the
2.45 GHz ISM band that precisely matched. Moreover, the fabricated prototype
has measured and simulated results have confirmed the antenna’s accuracy in the
reflection coefficient. Second, a highly efficient antenna may effectively
harvest the electrical energy by combining with the two-stage voltage
multiplier circuit presented at the ISM band. Furthermore, the proposed
rectenna has the optimum performance compared to state of art rectennas in
terms of efficiency, power range, and impedance bandwidth showing pronounced
achievement and increasing the DC output power significantly. The prototype is
fabricated and experimentally tested to confirm the concept. Measurement
results show that the proposed rectenna can be used for RF energy harvesting
applications.
