【Abstract】 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.更多还原
