摘　　要：针对普通微带天线频带窄,易导致无线电引信与其失配的问题,设计了一种弹箭引信用S波段宽频微带天线。该天线采用上下双层圆形介质基片,层间隔有金属层,背部探针馈电的结构,通过调整金属层厚度微调天线频带宽度。仿真与测试结果表明,天线体积小于Ф26mm×4mm,频带宽度大于150MHz,方向图前倾等优点,适合弹箭无线电引信应用。Due to the bandwidth of micro-strip antenna is narrow,which easily leads to mismatch problem with radio fuze.An broadband micro-strip antenna used in missile bomb was designed.It adopted the structure of double circular dielectric patch,up and down layer internal had a metal layer with back feed probe,by adj usting the thickness of metal layer tuning antenna bandwidth.The testing results showed that the antenna size was less thanФ26 mm×4 mm,the bandwidth was greater than 150 MHz,the direction pattern was forward-hemi-spherical.
