摘　　要：以某机载高频天线阵面结构设计为例,介绍了高频机载天线阵面的结构特点及其高精度结构设计的相关关键技术。对天线阵面的设计要求、天线系统组成和设备集成方式进行了介绍。重点对可插拔的一体化线源模块以及天线框架的高精度结构设计、热设计和天线阵面设备的密封设计进行了详细叙述。最后通过力学仿真分析,验证得出该天线阵面结构设计合理,刚强度满足设计要求。A high frequency airborne antenna is expatiated as an example to introduce the features and key technology of high precision antenna structural design. Antenna system composition and equipment integration method is introduced. The detachable integrated column module,Structural thermal design of the antenna framework,and hermetical design of the antenna＇s equipment are described in detail especially. The rationality of the structural design has been proved by the FEA,and the stiffness and strength can meet the design requirements.
