Abstract
This letter presents an efficient tri-band rectifier using a multistub matching network. Theoretical analysis of the tri-band impedance matching network consisting of the multistub is carried out, which shows that good input impedance matching can be achieved. For demonstration, a tri-band rectifier working at 0.915, 2.45, and 5.8 GHz is fabricated with dimensions of 44 × 35 mm. The measured results show that with a 1000 Ω load, the maximum efficiencies of the rectifier reach 76.7%, 74.4%, and 68.7% at 0.915, 2.45, and 5.8 GHz, respectively. This proposed efficient and compact rectifier has the potential application as an energy converter for battery-less electrical devices.
