【Abstract】 Thermal naalysis is a key technique in designing the antenna in a satellite. We use the finite-element method to calculate the large unfold antenna structure’s temperature distribution and thermal distortion, and study the influence of the basic structure’s parameters on the distortion of the antenna. The result of calculation will be beneficial to antenna design and the control of the antenna’s temperature.更多还原
