摘要
采用了FDTD算法,结合MATLAB软件对不同等离子体参数(密度、碰撞频率)及不同工作信号频段下的等离子体柱天线S参数和归一化电场辐射方向图进行了仿真计算;并分析了等离子体参数变化时所对应的天线电参数变化规律。研究结果表明:等离子体天线的各种电参数会随着等离子体参数及信号频率的变化而改变,进而达到控制等离子体天线辐射特性的目的。
The S parameters and normalization radiation patterns of plasma antenna were calculated in differentplasma parameters （including plasma electric density and collision frequency） and work frequency with finite- difference time-domain （FDTD） method and MATLAB software. Then analyzing the variation law of plasma anten-na electric parameter with plasma parameters being changed. The study result shows that the electrical parameters of plasma antenna can be varied by varing the plasma parameters and work frequency, Then the radiation character-istic of plasma antenna is controlled.
