摘　　要：设计了一种等离子半波天线构成的智能天线阵列。通过仿真分析,当选择合适的等离子特征频率和碰撞频率时,等离子天线阵列和金属构成的天线阵列具有相似的辐射特性。但是当等离子体停止激发时,等离子天线阵列有着比金属天线阵列低的RCS值,从而具有隐身的性能。A smart antenna array composed of plasma half-wave dipole is studied. When we choose the appropriate plasma eigen frequency and collision frequency, the plasma antenna array and antenna array composed of metal will have similar radiation characteristics through the simulation analysis. However, when we stop to stimulate the plasma, the RCS of plasma antenna array is lower than the metal antenna array. So plasma antenna array has stealth performance.
