The invention provides an unfolding mechanism of a multi-folding array unfolding antenna and a satellite, and relates to the field of spaceflight satellites, and an antenna unit comprises a plurality of first unit intermediate plates, a plurality of second unit intermediate plates, a plurality of unit upper plates and a plurality of unit lower plates. The first unit middle plates are sequentially arranged in the longitudinal direction, and the second unit middle plates are sequentially arranged in the longitudinal direction. The unit upper plates are sequentially arranged in the longitudinal direction, and the adjacent unit upper plates are connected through longitudinal hinge assemblies. The unit lower plates are sequentially arranged in the longitudinal direction, and the adjacent unit lower plates are connected through longitudinal hinge assemblies. A cross-plate driving assembly is arranged between the adjacent first unit middle plate and the adjacent second unit middle plate; the primary unfolding driving assembly is matched with the linkage part for driving longitudinal unfolding; and the at least two secondary unfolding driving assemblies are used for driving the unit upper plate and the unit lower plate to be transversely overturned and unfolded. According to the invention, after the array antenna is opened, a large aperture effect can be obtained.
