A Highly Efficient Energy Harvesting Circuit Using Luneburg Lens
This paper presents the design and analysis of a highly efficient energy harvesting circuit using a modified Greinacher rectifier and Luneburg lens at 2.4 GHz. The circuit is optimized for low power levels ranging from -30 dBm to -5 dBm. For 10 kΩ load, the rectifier provides an output voltage of 310 mV with a Power Conversion Efficiency (PCE) of 30.36 % for -15 dBm input power. RF power combining topology is used to combine power from multiple antennas. The use of Luneburg lens leads to an increase in received power because of its directional characteristics.
