Abstract:
A phase shifter includes a cavity (100) and a first fixed transmission line (301), a second fixed transmission line (302), and a slidable transmission line (201) that are located in the cavity (100). The first fixed transmission line (301) is provided with a first open slot (3011), the second fixed transmission line (302) is provided with a second open slot (3021), and opening directions of the first open slot (3011) and the second open slot (3021) are opposite to each other. Two ends of the slidable transmission line (201) are respectively clamped in the first open slot (3011) and the second open slot (3021), so that the slidable transmission line (201) is electrically connected to the first fixed transmission line (301) and the second fixed transmission line (302). The slidable transmission line (201) slides relative to the first fixed transmission line (301) and the second fixed transmission line (302).
