The phase shifter comprises a substrate, two identical copper circular pipes, a U-shaped circular bar, medium fixing blocks and a medium sliding block. The two copper circular pipes are fixedly arranged inside the medium fixing blocks in parallel. The medium fixing blocks are fixedly arranged inside the substrate. The inner circle diameters of the annular cross sections of the copper circular pipes are larger than the diameter of the circular cross section of the U-shaped circular bar. The two copper circular pipes are respectively inserted into two openings of the U-shaped circular bar and are coupled with the U-shaped circular bar. The middle part of the U-shaped circular bar is embedded into the medium sliding block which is slidably installed in the medium fixing blocks. When the medium sliding block slides in the medium fixing blocks, the U-shaped circular bar is driven to move in the copper circular pipes. According to the phase shifter, the length of the U-shaped circular bar in the fixing medium blocks can vary continuously so that linear variation in phase occurs in a transmission line. Therefore, the phase shifter has a great cross modulation characteristic, a larger phase shifting amount, and a smaller amplitude variation and phase shifting amount linear variation. The phase shifter has advantages of being simple in structure, smaller in size and small in width.
