The utility model is suitable for the technical field of antenna communication, and provides an antenna phase shifter device, which comprises a PCB (printed circuit board) provided with a feeder line; the coupling piece is used for being coupled with a feeder line on the PCB, and phase shifting is carried out by changing the coupling length; the pressure applying assembly is used for transmitting pressure to the coupling piece to drive the coupling piece to be coupled with the PCB; wherein the coupling sheet is of a sheet-shaped elastic structure; the pressure applying assembly comprises an overpressure limiting column used for limiting the pressure transmitted to the coupling piece by the pressure applying assembly. The overpressure limiting column is arranged in the pressure applying assembly, when the pressure of the pressure applying assembly is too large, the overpressure limiting column makes contact with the coupling piece for supporting, the pressure applying assembly is prevented from further applyin
