|With the continuous improvement of capability, the trend of miniaturization and light weight of satellite, the data transmission antenna should not only have the ability of multi-frequency band, high gain and high reliability, but also have the ability to resist the vibration or impulse of satellite launching and orbit change. Based on the design, production assembly and mechanical properties of the data transmission antenna, the structure is determined of the antenna’s main reflector, the RMS error, concentricity, height tolerance are calculated of the antenna. And the type and layout of the back-ribs are optimized by cut-and-trial. Finally, the rationality and reliability of the antenna structure are verified by simulation and vibration tests.
