Radio Frequency (RF) energy harvesting is emerging as a potentially reliable method to replace the costly and, difficult to maintain, source of low-power wireless sensors networks. In this paper, a dual-band RF-to-DC rectifier, that operates at LoRaWAN and GSM-900 cellular communication frequency bands, is presented. The system is composed of an impedance matching circuit, an RF-to-DC rectifier, that converts the ambient RF energy into DC voltage able to feed low power devices, and an output load. The proposed system resonates at two different frequencies of 866 MHz and 937 MHz. Numerical results demonstrate that the overall system exhibits an efficiency of 80% with 4.32 V of output voltage at 0 dBm of input power.
