Phase shifter

The utility model discloses a phase shifter, include: a feed layer, face and dorsal part are laid to the utensil circuit, the form circuit is laid the face and is equipped with band wire formula feed network, and this band wire formula feed network include: moving the looks unit, all being formed with two fixed transmission line segment and power distribution units of disconnection portion between the end and having the trimmers of band wire formula conductor including two, it includes and moves the looks unit and be towards relative working face that the working face is located to band wire formula conductor, and can fail length through the telex between the two fixed transmission line segments of displacement adjustment of band wire formula conductor and move the looks function in order to reach, the trace is located the circuit and is laid a last interval position department, and the trace is used and is driven the trimmer displacement, the corresponding position department of at least dorsal part on feed layer is located to the metal level, by this, structure form, the circuit welding parts that can simplify phase shifter feed network can reduce by a wide margin, move looks unit and power distribution unit and can integrate the shaping in same band wire formula feed network structure.
