Abstract
Modal analysis of an antenna support structure is earned out with the ANSYS program. Four-nodal quadrangular shell elements and the Block Lanczos method are used to analyze natural frequencies and corresponding modes of the structure. Furthermore, the effects of structural dimension parameters on the modes are investigated as shown in curves of structural natural frequencies with dimension parameters. The results show that structural dimension parameters greatly affect the modes of an antenna support structure.
