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.

Phase shifter and antenna

The present disclosure provides a phased array antenna, including a waveguide radiation unit, a phase shifter unit and a waveguide power dividing unit, a radiation patch and a first waveguide feed structure in the waveguide radiation unit are the same in number, and a first transmission port of each first waveguide feed structure is arranged corresponding to the radiation patch; the waveguide power dividing unit includes second waveguide feed structures, and a first transmission port of each second waveguide feed structure corresponds to a second feed region of at least one phase shifter; each of the first waveguide feed structure and the second waveguide feed structures includes a ridge waveguide structure; the ridge waveguide structure is provided with at least one sidewall; defining a waveguide cavity of the ridge waveguide structure; at least one ridge protruding toward the waveguide cavity is arranged on the at least one sidewall.
