摘　　要：分形由于其独特的结构及性能早已在天线的设计中有所应用,但较少地应用于天线雷达散射截面减缩。本文首次将分形思想应用到开槽微带天线中。设计了一副分形开槽微带天线,与常规微带天线相比,在辐射性能降低不多的同时较好地实现了整个频带RCS减缩。Fractal structure has been used for antenna design for the unique structure and performance, however it is seldom used in antenna radar cross section reduction. In this paper, fractal slot is used to reduce RCS of microstrip antenna for the first time. A fractal slot microstrip patch antenna is designed, comparing with the conventional microstrip antenna, RCS is greatly reduced with less loss in radiation performance within the operation frequency band.
