摘　　要：分析了影响微带天线 RCS的公式 ,利用公式对微带天线的 RCS减缩进行分析 ,计算了 RCS减缩效果和在此情况下天线的辐射性能。结果表明 ,微带天线 RCS与来波增益 ,天线本身增益和天线辐射效率有关。谐振点 RCS的减缩通常伴随着天线增益和辐射效率的下降。The formula of microstrip antenna′s RCS is studied, which is used to analyse RCS reduction, then calculate the effect on RCS reduction and the antenna′s performance in such cases. The results show that RCS is related to the plane wave′s gain, antenna′s gain and radiation efficiency. RCS at antenna′s operating frequency usually reduces with the drop of antenna′s gain and radiation efficiency.
