摘要：

In the electromechanical coupling analysis of reflector antennas, structural deformation is obtained by structure analysis software, deformation was introduced in the formula of antenna's far field patterns by phase difference. Based on structure mesh, far field patterns of antenna is calculated through the mesh transformation matrix and the beam breadth of half power is used to estimate the calculation range and the discrete precision of far field patterns. A verification experiment has been designed for verifying the new method via a 3.7 m Cassegrain antenna in Ku band. Results of experiment indicate that: the method in this paper is valid. Compared with integrated software method, the electromagnetic analysis precision improved computing time reduced.
