Implementation of Rectifier Circuits using Different Diodes for Wireless Power Transfer

several rectifiers using different diodes are presented in this work. The rectifiers are designed and tested for high power input RF conditions. The tested circuits are designed for 2.45 GHz of operating frequency, and implemented with radial stubs to obtain optimum matching conditions. The class- F design methodology is used here in order to suppress higher order harmonics. The results confirm that the rectifiers are efficiently converting the RF power in to usable dc power for a range of RF power values. Note that there are very few studies in the literature comparing currently available off the shelf diodes for RF rectification applications, making this paper a valuable design tool for efficient far field wireless power transfer systems.
