Abstract Traveling hexagon patterns have been observed in dielectric barrier discharge in an air-argon mixture. The phase diagram of hexagon pattern appearance as functions of applied voltage and air concentration is given. The spatial frequency of hexagon pattern increases with increasing applied voltage and air concentration. The current waveforms of hexagon pattern also vary with the air concentration. The drift velocity of traveling hexagon pattern changes from 4 mm/s to 18 mm/s.
