This article presents a novel multi‐band rectifier utilizing modified hybrid structure for radio frequency (RF) energy harvesting. The proposed multi‐band rectifier consists of a modified hybrid junction and three rectifying branches. The rectifying branches are placed inside the modified hybrid to reduce the layout size. The proposed multi‐band rectifier is designed for GSM‐1800, UMTS‐2100, and Wi‐Fi bands. Measured peak efficiency of the proposed rectifier reaches 61.7% at 9 dBm input power level. The results show a good overall performance on operation bands, efficiency, output voltage, and layout size. The proposed rectifier can be used for various RF energy harvesting applications, especially in the multi‐source condition.
