摘　　要：从保证天线的强度、刚度以及反射面精度等几个方面,介绍了某碳纤维复合材料天线的结构设计,并用有限元分析软件ANSYS10.0对该雷达天线进行了模态分析,得到了该天线的固有频率,确保满足系统对该天线抗振性能的要求。The structure design of a carbon fiber composite material antenna is presented from aspect of ensuring strength and rigidity of the antenna as well as accuracy of the reflector. The finite element analysis software ANSYS 10. 0 is used to do modal analysis of this radar antenna. The inherent frequency of this antenna is obtained, which can ensure satisfying requirements of the system for the antenna antishock performance.
