The basic situation of the 65 m antenna structure is introduced. The basic matrix equation and the load and boundary conditions for the 65 m antenna are given. The finite element analysis model is established according to the antenna structure and the antenna model Static and dynamic analyzes were performed to obtain the antenna accuracy and resonance frequency at a typical elevation angle. At the same time, the strength of the antenna model was analyzed, and the safety factor was obtained under different elevation angles and different working conditions. The results show that the antenna structure can meet the design requirements without any damage under the given conditions, which provides the basis for the structural design of the project.
