Low-power microwave rectifier based on high-Q-value inductor

The invention discloses a low-power microwave rectifier based on a high-Q-value inductor, and belongs to the technical field of microwave wireless energy transmission. The microwave rectifier comprises a 50-ohm matching microstrip line, a blocking capacitor, a T-shaped microstrip matching network, a rectifier diode, a high-Q-value inductor, a tuning microstrip line, a band-stop microstrip filter and a direct-current load. A high-Q-value inductor is introduced to the anode of the rectifier diode, the dynamic resistance loss of the diode in a sub-threshold region is obviously reduced, the rectification efficiency of the rectifier under low power is improved, and a single-diode parallel rectification structure is adopted, so that the rectifier has lower conduction voltage drop during forward conduction, and the power loss is reduced; in addition, a band elimination filter based on a multi-branch microstrip line is also introduced, so that second harmonic and third harmonic generated by a rectifier diode are effe
