Zusammenfassung:	Embodiments of the present invention provide a phase shifter and an antenna, and relate to the field of communications technologies. The phase shifter includes a cavity, and a fixed component, a sliding component, a control rod configured to control sliding of the sliding component, and a dielectric portion in the cavity. A first strip group is disposed in the fixed component, where the first strip group includes two strips. The sliding component is located above the fixed component, and a second strip group is disposed in the sliding component. The second strip group includes two strips, and the two strips of the second strip group are electrically coupled to the two strips of the first strip group respectively. Each strip of the first strip group and/or the second strip group includes a first strip portion and a second strip portion, and a width of the first strip portion is greater than a width of the second strip portion. The dielectric portion is disposed around the second strip portion, and a difference between an impedance formed by the dielectric portion and the second strip portion and an impedance of the first strip portion is within a first range. This can reduce a size of the phase shifter.
