摘要
设计了一种弹载微带准八木天线阵,该阵列与弹体曲面共形,不影响弹体的动力学特性,也不损伤弹体的机械强度。利用HFSS电磁仿真软件对模型进行仿真,同时针对实际安装过程中出现的公差进行了分析,以指导加工实物的安装。该天线的辐射方向图为后向锥形波束,增益为2.8d Bi,整个工作频段内辐射特性稳定,符合性能要求。
A kind of missile- borne Quasi- Yagi antenna array is designed. The array is coformed with curved place of mssile,which will not effect dynamic characteristic of the missile,nor damage mechanical strenght of msiisle. The Model is simulated by using HFSS electromagnetic simulation software; and the tolerance occurred during pratical installion is analzyed so as to guide installation of the fabricated real object. The radiation pattern of the antenna is backward conical beam,with gain of 2. 8d Bi and stable radiation characteristics in operating frequency band,and this tally with requirement for performance of antenna.
