摘要
叙述了等离子体柱的产生,并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。参考传统金属天线辐射场的求解方法,在简化的条件下求得了等离子体柱天线行波传输和驻波对称振子结构等离子体天线驻波传输的电场辐射方向图,结合方向图,分析了等离子体参数变化时对应辐射方向图的变化规律,证实了等离子体柱天线方向图的可控性,同时,也说明了利用等离子体柱天线进行信号传输有一定的应用价值。
The development of plasma column is described in this paper. The feasibility of replacing metal by plasma column in making the fundamental antenna vibrator is analyzed. According to approach to radiation pattern of metal, the radiation patterns of traveling wave in a plasma antenna and standing wave transmitting in a plasma dipole antenna in simple condition are calculated. Based on the radiation patterns, the variation law of radiation pat- terns for plasma parameters being changed is analyzed, the controllability of plasma column antenna′s radiation patterns is confirmed, and the result shows that utilizing plasma column antenna for transmitting signals is of certainvalue in application.
