| 摘 要： | 本文提出了一种工作在超高频(Ultra High Frequency, UHF)的理想等离子体螺旋天线。通过数值仿真，研究了等离子体天线辐射特性与等离子材料参数之间的关系。仿真结果显示，当满足等离子体频率大于约10倍工作频率和碰撞频率小于等离子体频率的条件时，等离子体天线具有与金属天线相似的辐射特性。此外，两者的相似程度与等离子体频率成正比，与碰撞频率成反比。

| Abstract: | An ideal helix plasma antenna operating in the Ultra High Frequency (UHF) band is studied in the paper. By using numerical method, the relationship between the radiation characteristic of the plasma antenna and the plasma parameters is revealed. The simulation results indicate that, when the plasma frequency is higher than ten times operating frequency and the collision frequency is lower than plasma frequency, the antenna has the same characteristic with the metal one. Moreover, the similarity level of characteristic is direct proportional to plasma frequency and inverse proportional to collision frequency. |
