Cross vibrator plasma antenna

A cross vibrator plasma antenna comprises an antenna vibrator array component, a plasma excitation component and a phase shift component. The antenna vibrator array component comprises four antenna vibrators, every two adjacent antenna vibrators are perpendicular, and every two opposite antenna vibrators form a half-wave symmetrical vibrator group. The plasma excitation component is connected withthe antenna vibrators in the antenna vibrator array component and used for generating high-density plasmas and keeping operation of the antenna vibrators. The phase shift component is connected withthe antenna vibrator array component and used for realizing quick shifting of the cross vibrator plasma antenna between online polarization and circular polarization. Shifting among horizontal polarization, vertical polarization, left-hand circular polarization and right-hand circular polarization is realized, various polarization signal processing capabilities are improved, an antenna adjustablerange is expanded, and exte
