当前国内学者对等离子体天线的研究主要集中于柱状天线和反射面天线, 而在国外已有学者以等离子体阵列结构设计了功能多样的智能天线系统. 为了较系统地了解这一新的设计思路, 基于等离子体散射理论对中心单元激励的圆形定向天线阵进行了理论和实验研究. 设计了一个16元等离子体无源振子的圆形天线阵, 实现了天线电磁波单波束和多波束的定向辐射. 通过理论计算和分析, 阐述了天线电磁波单波束和多波束辐射的原理. 通过建立实验系统, 测试了圆形天线阵的定向辐射特性. 实验结果和理论值接近, 说明该等离子体圆形天线阵可以实现天线电磁波的定向辐射和多波束辐射. 另外, 该天线阵还具有快速切换辐射方向、参数快速重构、雷达隐身性良好的优点.Domestic scholars are often concerned with the characteristics of the plasma cylindrical antenna and the plasma reflector antenna. However, foreign scholars have begun to study the plasma array antenna and used it to design smart antenna. In order to understand this new design idea, based on the plasma electromagnetic scattering theory, a theoretical and experimental study on the directive circular antenna array with a center element driving is presented. A sixteen-element plasma passive oscillator circular array, the mechanism of whose single-beam and multi-beam is transmitting, is established. And an experimental system is established to test the radiation result of circular antenna array. The measured results of radiation patterns are in good agreement with the computational values, verifying that electromagnetic waves can be directional and multi-beam transmitted in this circular antenna array. The advantages of this antenna array are fast switching of the radiation parameters, rapid reconstruction, radar stealth and so on.
