| Abstract: | A 3D model of antenna pedestal is obtained in the software of UG to address actual engineering needs. Then after setting boundary condition and the range of frequency, the stress and modal analysis of the model is made in NX Nastran. The results show that the optimized structure increases its inherent resonant frequency and that all mechanical characteristics of the antenna pedestal satisfy the design requirement. |

| Keywords: | modal analysis antenna pedestal FEM inherent resonant frequency |
