Title:
PHASE SHIFTER
Document Type and Number:
WIPO Patent Application WO/2016/037549
Kind Code:
A1
Abstract:
A phase shifter comprises a cavity (100), a first fixed transmission line (301), a second fixed transmission line (302) and a slideable transmission line (201), wherein the first fixed transmission line (301), the second fixed transmission line (302) and the slideable transmission line (201) are located in the cavity (100). A first open slot (3011) is formed in the first fixed transmission line (301), a second open slot (3021) is formed in the second fixed transmission line (302), and openings of the first open slot (3011) and the second open slot (3021) face toward each other. The two ends of the slideable transmission line (201) are clamped in the first open slot (3011) and the second open slot (3021) respectively, so that the slideable transmission line (201) can be electrically connected to the first fixed transmission line (301) and the second fixed transmission line (302), and the slideable transmission line (201) slides relative to the first fixed transmission line (301) and the second fixed transmission line (302). By the adoption of the phase shifter, the slideable transmission line can be effectively coupled to the fixed transmission lines, the structure is simple, and the requirements for a transmission device are low.
