A dual-band relativistic backward-wave oscillator(RBWO) with dual annular electron beams generating C-band and X-band microwaves is investigated by particle-in-cell (PIC) simulation. Two separated beam-wave interaction regions are supplied to obtain independent generation processes of the dual-band microwaves. With the diode voltage of 650 kV, the inner beam current of 5.4 kA and the outer beam current of 6.4 kA guided by a magnetic field of about 2.2 T, the dual-band microwaves are generated with dominant frequencies of 4.625 GHz and 8.450 GHz. The powers of the dual-band microwaves are 920 MW and 600 MW with efficiencies of 21.8% and 17.1%, respectively. The influence of the guiding magnetic field, diode voltage and key structure parameters on the powers and frequencies of the dual-band
