Design of Rectifier at ISM Band for RF Energy Harvesting of Low Powers

This paper presents the analysis of a single band rectifier operating at 2.45 GHz. Harvesting energy in the lower powers is a common challenge. This work is targeted to improve the efficiency in lower powers of -10dBm to 0dBm. A voltage multiplier is considered as a rectifier here. The simulated rectifier gives an output voltage of 0.379 volts with a power conversion efficiency of 28%. For 0 dBm input power, the output voltage is 1.45 volts and efficiency is 42%. L-matching circuit using single stub matching technique is used as matching network.
