Rectenna circuit topologies for contactless energy transfer
Vlad Marian1, Christian Vollaire1, Jacques VERDIER2, Bruno Allard1

This paper describes several rectifying antenna (rectenna) circuit topologies designed for microwave contactless energy transfer, depending on the desired application and input power range. Circuits for low, medium and high power density are presented. Applications include wireless supply of sensors or other low power devices over distances of several meters. High sensitivity designs offer the possibility of harvesting ambient microwave energy. The circuits presented are tuned for a central frequency of 2.45 GHz.
