Abstract:In order to improve the performance of Radio Frequency Identification(RFID) microwave rectifiers with microwave Schottky diodes, a compact microwave rectifier at 915 MHz was designed based on microstrip transmission lines in this study. The measured results show that the rectification efficiency is above 60% over the range of input microwave power from 13 dBm to 22 dBm. In the future, the performance of the rectifier can be further improved with better circuit designs, and it can be applied to microwave wireless power transmission systems and RFID rectennas.
