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