DESIGN OF RF TO DC CIRCUIT FOR ENERGY HARVESTING

Abstract: This article describes an RF-to-DC energy harvesting circuit designed using a microstrip patch antenna, impedance matching network, and voltage doubler rectifier. The design was implemented in Keysight ADS software. The microstrip patch antenna operates at 915MHz, and the impedance-matching network ensures efficient power transfer. The voltage doubler rectifier achieves an output voltage of 2.305 V and a current of 0.006 mA and an input of 17 dBm and a Radiation intensity of 60%. This research demonstrates a promising method for collecting radio frequency and establishes the foundation for future research into low-power applications
