Abstract
A phase shifter includes a signal line and a reference electrode respectively disposed on sides of different ones or both disposed on a same side of a same one of a first base plate and a second base plate proximal to a dielectric layer, and includes a straight unit and a bent unit along an extending direction of the signal line. The signal line includes a first signal sub-line corresponding to the straight unit and a second signal sub-line corresponding to the bent unit, and the reference electrode includes a first reference sub-electrode corresponding to the straight unit and a second reference sub-electrode corresponding to the bent unit. The second signal sub-line and the second reference sub-electrode which correspond to the bent unit are configured to make an impedance of the bent unit match to an impedance of the straight unit and/or an impedance of another adjacent bent unit.
