Three-Stage Voltage Doubling Model of RF Microstrip Patches Antenna of 900 MHZ for Charging

The harvesting circuit using the 900 MHz microstrip patches antenna and therefore the Schottky diode rectifier. The aim of this circuit is to rework the radio frequency signals within the GSM frequency band to DC (DC) voltage. This research also provides a suggestion for the design of the 900 MHz microstrip patch antenna utilized in the circuit. The rectifier design is predicated on the doubler circuit of Villard voltage developed at 900 MHz. Three-stage voltage doubling is modeled and simulated in this project. The proposed antenna harvests the RF power and transforms it into DC voltage ranging up to 7.5 V which will be utilized in low-power DC applications.
