A Dual-Band Rectifier Using Half-Wave Transmission Line Matching for 5G and Wi-Fi Bands RFEH/MPT Applications

A dual-band rectifier is presented for RF energy harvesting (RFEH) and microwave power transfer (MPT) applications. Starting with a single-band rectifier, the second band is added by utilizing a half-wavelength transmission line (HWTL) in the matching network (MN). A series diode topology using HSMS-2860 Schottky diode is used for power conversion. The rectifier simultaneously harvests the RF energy with power conversion efficiency (PCE) of 54.9% and 42.3% and output voltage of 1.4 and 1.242 V at 0-dBm input power for 3.5-GHz 5G band and 5.8-GHz Wi-Fi band, respectively.
