摘要 根据潘宁气体放电的物理特性,定性分析了等离子体天线中氦氩潘宁气体放电的特性,实验测量了充满氦氩潘宁气体的等离子体天线与充满纯氦或纯氩等离子体天线的等离子体长度、等离子体密度,得出等离子体天线中充入氦氩潘宁气体时,在同等条件下能使等离子体天线的有效长度更长,等离子体密度更高。等离子体密度对天线的辐射效率和隐身性能影响很大,因此研究氦氩潘宁效应存在时表面波等离子体柱的等离子体长度与所加射频功率的关系和等离子体密度沿天线的分布对于提高天线的辐射效率和隐身性能至关重要。 Based on the physical characteristics of Penning gas discharge,the characteristics of He-Ar Penning gas discharge in plasma antennas were analyzed qualitatively.Plasma length and plasma density were measured in plasma antenna filled with both He-Ar Penning gas and pure He or Ar.The results showed that the plasma antenna filled with He-Ar Penning gas can make the effective length of the antenna longer and the plasma density higher under otherwise equal conditions.The radiation efficiency of the antenna and its invisibility are significantly affected by plasma density.So,it is crucial to the improvements of antenna＇s radiation efficiency and invisibility：to investigate the relation between the length of surface wave plasma column and input RF power when the Penning effect is found at that time and the plasma density distribution along the antenna.
