The power capacity of a 36-element high power helical array antenna fed from double-layered radial waveguide is investigated. Two breakdown conditions are discussed, which are breakdown under vacuum condition and breakdown on the medium surface. Based on those breakdown threshold values, the power capacity of the antenna is analyzed theoretically and qualitatively and simulated. The simulation results are presented and the reasons for capacity debasement are analyzed. Methods for improving the power capacity are discussed. The results show that the power capacity of the improved antenna can reach 1 GW.
