The basic status of 65 m antenna structure is introduced,and the basic matrix equations of FEA with load and boundary conditions of 65 m antenna are provided. According to the structural form, the FEA model is built. With the statics analysis and dynamics analysis to the antenna model, the resonance frequencies and accuracy of antenna structure at typical elevation angles are obtained. Mean while, with the strength analysis to antenna model, the strength safety coefficients of antenna structure at different elevation angles and operating conditions are obtained. The results show that the antenna structure can meet the design requirements at given conditions, and no breakages can occur. And the conclusion provides warrant for structure design of the project.
