Abstract Solid-surface reflector is widely used in satellite aperture antenna because of its high surface accuracy. Aiming at the problem that the overall reliability of the petal rotation solid-surface deployed antenna is affected by the large number of rotating pairs, the equivalent transformation principle and the corresponding design method of the solid-surface deployed antenna rotating along two orthogonal axes and a single axis were investigated, and the effectiveness of deployed antenna rotating along a single axis was verified by an example. The results showed that the number of rotating pairs of petal rotating deployed antenna was reduced to improve the overall stability and deployable reliability of the antenna, which is of great reference value for the design and analysis of solid-surface deployed antennas.
