A novel dual-frequency rectifier based on a 180° hybrid junction for RF energy harvesting

Abstract : This paper reports the design and experimental characterization of a dual-band rectifier, based on a 3 dB 180° hybrid junction, and dedicated for electromagnetic energy harvesting. The proposed circuit achieves comparable performances at 1.8 and 2.45 GHz. DC output voltages higher than 900 mV and efficiencies more than 49 % were measured over a resistive load of 8.8 kΩ and for an RF input power of -10 dBm (100 μW). The rectifier is powered by an RF signal including the two frequencies of interest.
