基于等离子体无源振子定向天线阵的理论及仿真分析

内容简介：在电子密度很高的条件下,基于非磁化冷等离子体介质对电磁波反射率较高的原理,设计了一款以多根柱状等离子体介质作为无源振子、一根全向天线作为辐射源的定向天线阵.通过仿真分析,得到定向天线阵的3D方向图,发现定向天线阵具有很好的波束约束性,能实现天线波束的定向传播.

Abstract：Based on the principle that non?magnetized cold plasma has the strong reflection effect on electromagnetic waves,a new directional antenna array was designed. The directional antenna array was represented by a plurality of plasma cylinders and an omni?directional antenna. The 3D pattern of the directional antenna array obtained from simulation analysis shows that the directional antenna array has many advantages such as transmittering directional beam,quick switching direction,rapid reconstruction,radar stealth and so on.
