Abstract
A multiband rectifier was designed according to multiple resonator networks by simultaneously matching the rectifier at different frequencies (1.3, 1.7, 2.4, and 3.6 GHz). The rectifier can simultaneously harvest energy from RF sources at the L-band (1-2 GHz), GSM1800, Wi-Fi bands, and long-term evolution. Through sequential application of the resonator networks during the rectifier-matching process, the resonance characteristic of the resonator facilitates the nearly independent design of each matching frequency. A fabricated prototype showed a 1-V output voltage when the input power was set at-11 dBm for each of the four RF bands with a 3-k Ω load.
