摘　　要：文中基于微带天线的开槽技术和短路针加载技术,设计了低雷达散射截面(RCS)的微带天线.将分形技术应用于微带天线RCS缩减中,设计了单辐射边分形低RCS微带天线.研究结果表明:微带贴片天线在1~12GHz的频带内实现天线RCS缩减,最大缩减幅度为20dB.基于分形技术的微带天线实现了天线带内、带外RCS同时缩减.A low radar cross section （RCS） microstrip antenna was designed based on the slotting method and short circuit loading technology. Besides, another low RCS microstrip antenna with single fractal is designed with the use of fractal technology. The results show that the proposed antenna RCS is reduced in the frequency range ftom 1 to 12 GHz with the maximum reduction of 20 dB,and that the in- band and out-of-band RCS can be obtained simultaneously by this single fractal microstrip antenna.
