摘　　要：针对传统单极子天线在X波段体积大,不利于常规炮弹引信小型化的问题,提出了小型化X波段介质加载单极子天线。该天线的辐射单元采用空心棒状结构,通过锥形过渡结构与同轴馈线连接,辐射单元内嵌在介质套筒中与抛物面底板通过台状结构咬合固定。测试表明:天线尺寸相对于传统单极子天线减小30%,带宽增大50%。该天线有利于引信的小型化,可以应用于多种无线电探测引信中。For solving the problem that traditional X-band monopole antenna has large volume,which is not suitable for conventional shell fuze miniaturization,we proposed miniaturized X band dielectric loaded monopole antenna. The radiation unit of the antenna used hollow rod like structure,and through the coaxial feeder connection,radiation unit was embedded in the bottom plate of the medium sleeve with a parabolic shape through shaped structure to bite fixed. The test shows that the antenna size relative to the conventional monopole antenna is reduced by 30%,increasing 50% bandwidth,for fuze miniaturization can applied to a variety of radio detection fuze.
