1800 MHz and 2.45 GHz Antennas for RF Energy Harvesting Applications

The proposed antenna in this work is intended to function at GSM 900 and GSM1800 IOT applications. The last few years have seen a surge in interest in obtaining energy from environmental sources, particularly electromagnetic waves. The ability to receive microwave radiation and convert it to DC power using radio frequency rectennas(receiving antenna + rectifying circuit)has lately come to light. Our goal is to simultaneously increase bandwidth, efficiency, and gain. The proposed antenna in this work is intended to function at 1800MHz and 2.45GHz. The simulated antenna's return loss S11 reaches a bandwidth that is 75MHz@1800 MHz and 88MHz@2.45 GHz band.
