摘要：
The frequency dependence of plasma-column antenna input impedance has been measured by a vector network analyzer with different applied exciting power. The experimental results show obvious resonance behavior of the impedance. The effect of plasma parameters on the input impedance was established by means of an equivalent circuit model and the characteristics of input current. This method is useful for the research of plasma antenna dynamic reconfiguration and the realization of fast impedance matching.
