摘　　要：传统引信装置是独立的部件,其天线设计无需考虑周围结构对其性能的影响。未来的导引头系统期望引信天线和雷达天线能够一体化紧凑型共面设计,这会使导引头雷达的阵列天线对引信天线存在必然的干扰,导致其性能恶化、方向图畸变等。针对这些问题,本文提出了一种与阵列天线紧凑型共面的引信天线,该引信天线综合采用了加载感性枝节的带状线馈电结构、H型缝隙、倒F结构、寄生反射贴片、波束展宽金属栅栏、介质内嵌空腔等结构,同时获得小型化、宽带和相对对称的宽波束特性。实测结果充分验证了设计的合理性和工艺的可行性,该方法对于其它共口面天线及阵列设计具有重要的借鉴意义。The traditional fuze device is an independent component.The surrounding influence on its antenna does not need to be considered.However,the future seeker system is developing towards miniaturization.In order to solve the problem,a compact coplanar fuze antenna with the radar array antenna is proposed.The joint action of stripline feed structure loaded with inductive branches,H-shaped slot,Inverted-F,parasitic reflection patch,beam broadening metal fence,dielectric embedded cavity and other structures,miniaturization,broadband and relatively symmetrical widebeam characteristics are simultaneously obtained.The measured results fully verify the rationality of the design and the feasibility of the process,and the method has strong reference significance for other common-port antenna designs.
