摘　　要：在传统八木天线理论基础上,设计了一款等离子体八木天线,通过CST软件仿真得到其S11参数、辐射方向图,并根据软件仿真优化参数加工制作出等离子体八木天线原理样机,用高性能矢量网络分析仪对原理样机的S11参数进行了测量。结果表明,当等离子体密度较高时,等离子体八木天线具有很好的定向性以及较高的增益,具有与金属天线可比拟的性能。A plasma Yagi antenna was designed based on the traditional theoretical analysis of Yagi antenna, 311 pa- rameter is patterns were simulated by CST software. According to the simulation, we manufacture plasma Yagi antenna prin- ciple prototype and Sn parameter is measured by a vector network analyzer ,which is consistent with the simulation results . The results show that the plasma Yagi antenna has good directivity and high gain as the plasma density is high enough. The performance can be compared with the metal antenna.
