摘　　要：文中首次将Koch分形与H形开槽相结合应用于微带贴片天线RCS减缩中。设计了一副分形开槽微带天线,与工作在同一频率的矩形微带天线进行了比较,天线增益损失只有0.8dBi,而天线的谐振峰值却得到了有效控制,天线RCS在带内减缩1.8dBsm,在带外实现2dBsm～14dBsm的RCS减缩。设计天线具有较好的辐射特性和散射特性。This paper is the first to reduce Radar Cross Section （RCS） of the microstrip antenna by using Koch fractal and H-Shaped cutting slots. A fractal slot microstrip antenna is designed. Compared with the rectangular microstrip antenna working at the same frequency, its gain loss is only 0. 8 dBi. The resonant frequency peaks are efficiently controlled and the RCS reduction in band is 1.8 dBsm with 2 - 14 dBsm out of band. The designed antenna has good radiation and scattering performance.
