This paper analyzes the RF-DC conversion efficiencies of the concurrent dual-band rectifier with controlling the spur signals generated by mixing the input signals. The proposed concurrent 2.45/5.8GHz dual-band rectifier drastically improves its conversion efficiency with a spur signal control technique. The proposed rectifier employs two key designs. A microstrip spurline notch filter in the output section realizes high conversion efficiencies at the dual bands. The quarter-wave length open stub of the 8.25 GHz connected at diode cathode effectively terminates the spur signal. The proposed configuration provides the high conversion efficiency even when two-tone signals input the rectifier.
