The occupied space of the connecting plate 14 in the length direction of the antenna is small, and the structural design layout is convenient. Meanwhile, when the connecting plate 14 is connected with all the medium connecting pieces 13, all the phase shifter medium plates 121 can be connected with the connecting plate 14 at the same time only by applying a small pushing force to the connecting plate 14, and the installation steps are extremely simple and efficient.
