Abstract
A multi-layer phase shift driving device for an electrically regulated antenna includes multiple control boards that are spaced apart from each other, each of which is arranged with respective phase shift driving mechanisms for driving brushes of the electrically regulated antenna, and arranged with a plurality of holes through which rods pass, wherein each control board is provided with at least one of said rods fixed thereto to serve as fixing rods of the control board and serve as guiding rods of the other control boards of the multiple control boards, such that the multiple control boards can be driven independently of each other.
