Enhancing Electric Vehicle Battery Longevity Through Radio Frequency Energy Harvesting

This research work focuses on presenting a radio frequency (RF) energy harvesting structure, which aims to power the load through the absorption of electromagnetic radiation in the 2.4 GHz Wi-Fi frequency band and N78 3.5 GHz 5G band. A superpatch microstrip antenna is specifically designed to operate at a frequencies of 2.4 and 3.5 GHz, while possessing a 50 Ohm impedance. Utilizing 3D Electromagnetic simulation tools, the antenna structure is created and tested. An RF to DC converter is implemented using a seven-stage voltage doubler. The rectifier circuit is simulated using Multisim software. The outcomes demonstrate that the RF energy harvesting system produces the required voltage to power the load.
