This paper reports an efficient rectifier operating at 2.45 GHz for wireless energy harvesting applications with low input power levels. Single diode shunt-mounted topology is adopted for operation with low input power level.
The efficiency is measured as 27.7% at -20 dBm of input power, 39.2% at -15 dBm, and 51.2% at -10 dBm. The maximum efficiency of 61.7% is measured at -0.4 dBm input power.
