Disclosed is a parallel type six-freedom-degree redundant driving antenna structural system. The parallel type six-freedom-degree redundant driving antenna structural system comprises an antenna reflective surface and an antenna pedestal, wherein the antenna reflective surface is linked on the antenna pedestal; the antenna pedestal comprises a fixed platform and a movable platform which are arranged in parallel; the fixed platform is a convex circular table with gradually decreased caliber; three groups of guiding rail units are uniformly distributed on the fixed platform; each guiding rail unit group consists of two guiding rails; each guiding rail is equipped with a driving sliding block; a telescopic unit is hinged on each driving sliding block in a one-to-one correspondence manner; all the telescopic units are hinged to the movable platform; each movement point can perform coordination action by following four movement units, so that special forms and positions can be effectively reduced; the convex circular table shape of the fixed platform is matched with the driving sliding blocks to realize overturn of the antenna; the multiple driving sliding blocks are matched with the telescopic units to perform a coordination operation, so that not only all-around tracking of the antenna, but also negative angle pitching of the antenna can be realized; and consequently, the stability, flexibility and rigidity of the mechanism are highly reinforced.
