A compact and efficient graphene FET based RF energy harvester for green communication
This paper presents a graphene field effect transistor (FET) based rectenna with substrate-
integrated waveguide (SIW) broadband approach for RF energy harvesting application. The
proposed structure of integrated rectenna consists of a graphene FET rectifier and an SIW
antenna operating in the (S 11<− 10 dB) range of 29–46 GHz. The peak gain of the SIW
antenna observed is 8.12 dBi. In addition, a new matched circuit consisting of microstrip line
and butterfly stub (without using any lumped elements) is designed. The matched circuit …
