Folded Dipole Antenna with Class-F Load Function for Rectenna of Microwave Power Transfer

抄録

A folded dipole antenna with a class-F load, acting as a receiving antenna for microwave wireless power transfer, is proposed. Conventionally, a class-F load circuit and matching circuit are connected to a rectifier circuit. A capacitor is used to adjust the impedance for harmonic waves. The proposed antenna involves both the class-F load and matching circuit functions to decrease loss in the circuit and reduce space usage. The antenna design was optimized and demonstrated to verify the class-F function.
