In this study, we experimentally investigated the discharge characteristics of argon and helium dielectric barrier discharges with coplanar electrodes at intermediate pressure to reduce the radar cross section for plasma-based stealth applications. The discharge patterns of argon and helium were investigated according to the pressure, driving frequency, and gas ratio with a fixed input voltage, and the discharge voltages and currents were measured. The power dissipated by the device in one cycle was calculated using the measured values. From the discharge pattern and measured values, we confirmed that a bright glow discharge occurred at a few Torr of argon and tens of Torr of helium, and the discharge was brighter and more uniform in the driving frequency range 5–6 kHz. When a mixture of the two gases was used at tens of Torr, the brightness of the discharge pattern and the number of current pulses increased with the proportion of helium, while the intensity of the current pulses decreased. We confirmed that an efficient and stable discharge can be generated at frequencies 5–6 kHz using several Torr of argon or tens of Torr of helium.
