| 对使用等离子体代替金属用来构成最基本的天线振子的可行性进行了分析，得出了在一定条件下等离子体天线可以取代金属天线的结论，参照传统金属天线辐射场的求解方法，代入等离子体特征参数对等离子体柱天线的电场辐射方向图进行了模拟，并分析了等离子体参数变化时对应辐射方向图的变化规律.模拟结果表明：等离子体天线辐射方向图会随着等离子体密度、碰撞频率等参数的变化而改变.等离子体天线因此具有辐射方向可控的特点. |

| This paper analyzed the feasibility of replacing metal by plasma column in making the fundamental antenna vibrator in and come to the conclusion that Plasma antenna can replace metallic antenna on certain conditions.Then according to approach to radiation pattern of metal,the radiation patterns of plasma antenna is calculated.Furthermore,the variation law of radiation patterns for plasma parameters being changed is analyzed.The result shows that the radiation pattern of plasma can be varied by varing the plasma parameters including plasma electric density and collision frequency.The plasma can be used as antenna vibrator with the advantages of reconfigurability. |
