| Zusammenfassung: | The embodiment of the invention provides a phase shifter. The phase shifter comprises a cavity, a first fixed transmission line, a second fixed transmission line and a slideable transmission line, wherein the first fixed transmission line, the second fixed transmission line and the slideable transmission line are located in the cavity; a first open slot is formed in the first fixed transmission line, a second open slot is formed in the second fixed transmission line, and the open direction of the first open slot is opposite to that of the second open slot; the two ends of the slideable transmission line are clamped in the first open slot and the second open slot respectively so that the slideable transmission line can be in electric connection with the first fixed transmission line and the second fixed transmission line, and the slideable transmission line slides relative to the first fixed transmission line and the second fixed transmission line. By the adoption of the phase shifter, the slideable transmission line can be effectively coupled with the fixed transmission lines, the structure is simple, and the requirements for a transmission device are low. |
