摘　　要：利用CST电磁仿真软件,建立了智能等离子体天线的仿真计算模型,研究了等离子体的电子密度和碰撞频率对智能等离子体天线辐射性能的影响,在此基础上,分析得到了智能等离子体天线的等离子体参数需求。对于智能等离子体天线,为了提高其最大辐射增益,应尽可能提高柱状等离子体的电子密度,同时降低其碰撞频率,并且在电子密度和碰撞频率提高相同倍数的情况下,电子密度的影响大于碰撞频率的影响。Using the CST electromagnetic simulation software, a simulation model of an intelligent plasma antenna was founded. Then effects of the electron density and collision frequency on performances of the intelligent plasma antenna were studied. Based on the results, requirements of plasma parameters for the intelligent plasma antenna were investigated. As for an intelligent plasma antenna, its maximum gain increases with higher electron density or lower collision frequency. Moreover, the electron density is more important to the maximum gain than the collision frequency when they augment with the same times.
