| Abstract(in English) | This paper proposes and demonstrates a concurrent 2.45GHz/5.8GHz rectifier. The proposed concurrent dual-band rectifier drastically improves its RF-DC conversion efficiency with a harmonic signal control technique. The proposed rectifier employs two key designs. A microstrip spurline notch filter in the output section realizes high RF-DC conversion efficiencies at the dual bands. The quarter-wave length open stub of the 8.25 GHz connected at diode cathode effectively terminates the harmonic signal generated by mixing the input signals. The proposed configuration provides the high RF-DC conversion efficiency even when two-tone signals input the rectifier. The fabricated the dual-band rectifier achieves the RF-DC conversion efficiencies of 64.8 %, 62.2 %, and 67.9 % at 2.45 GHz, 5.8 GHz, and their two-tone input signals, respectively. |
