摘　　要：针对引信微小型化的需求,集成设计了毫米波频段基于基片集成波导的缝隙阵列天线和T型功分器的天馈系统架构。利用基片集成波导的柔韧性,将功分器弯曲共形贴敷在圆筒侧壁,两个输出端口分别对圆周间隔180°的两个SIW缝隙阵列天线馈电。仿真结果表明,基于SIW的缝隙阵列天线系统实现了空心漏斗形状方向图,且系统结构布局占用空间体积小、质量轻,适用于引信天馈单元的微小型化。Considering the requirement for fuze miniaturization, a kind of integrated and miniature slot array antenna and T-junction power divider which is based on substrate integrated waveguide were designed. Based on flexibility of SIW, T-junction power divider is kept close to cylinder side and two outputs ports used to respectively feed in back to back SIW slot array antenna. Simulation results show that the SIW slot array antenna achieves funneled radiation pattern, and the configuration is small in size and light in mass, which is fit for desig- ning miniature fuze antenna and feed system.
