The invention provides a vacuum thermal test method for an ultra-large-diameter antenna along with a whole satellite, and the method comprises the steps: arranging a satellite and the antenna in a vacuum tank, arranging the folded antenna at the two sides of the satellite, respectively arranging heating assemblies at the periphery of the satellite and the heat dissipation surface of the antenna, and simulating an external heat flow, and adjusting the folding angle of the antenna according to the thermal radiation level of the satellite and antenna surface, and carrying out vacuum thermal test on the satellite and antenna after adjustment. According to the vacuum thermal test method for the ultra-large-diameter antenna along with the whole satellite, the situation that the vacuum thermal test is carried out in batches due to the antenna size can be avoided, the test time and personnel allocation can be greatly shortened by placing the antenna and the whole satellite in one tank, and the purposes of shortening
