Abstract:

Thermal-structural deformation caused by clear-day solar radiation will effect the electrical parameters of ground reflector antennas. For this problem, temperature field analysis model is proposed firstly. The temperature and the structure deformation of antenna could be obtained with ANSYS software. Secondly, a temperature experiment ha...More
