An Investigation of a Matching Circuits for Radio Frequency Energy Harvesting Applications

This paper presents HSMS 286C diode is used as a voltage doubler (VD) circuit, different types of matching circuit has been investigated for a VD rectifier circuit with a load resistance of 3 KΩ. Matching networks for efficient RF to dc voltage conversion. For lumped, transmission line, Rogers 4350 and FR4 substrates have investigated, efficiency of the rectifier matching circuits are 80.5%, 81.2%, 62% and 32.7% respectively. For transmission line matching networks, the maximum conversion efficiency has been attained, and the overall output voltage is greater than 5 volts at an input of 20 dBm with a 3 KΩ load resistance.
