摘　　要：利用全波分析方法对有耗矩形微带贴片的辐射特性进行了研究 ,建立了同时考虑介质和贴片损耗的电场积分方程 ,并推导了此时雷达截面与辐射效率的关系式 .结果表明通过改变表面电阻能够有效地降低微带贴片天线的雷达截面 .The scattering properties of a lossy rectangular microstrip patch are examined by full wave analysis. The electric field integral equation(EFIE) is developed including dielectric and patch losses. A general scattering formula is derived for the radar cross section (RCS) and the radiation efficiency of the body. The results show that a surface resistance can reduce the RCS of the microstrip patch efficiently.
