Claim 14:
15. A base station, comprising:
an antenna, comprising a phase shifter, the phase shifter comprising:
a cavity;
a metal strip line disposed in the cavity; and
a tuning accessory, comprising a physical connector and a component connected to the physical connector, wherein the physical connector is configured to fasten the component to the cavity, the component is disposed in the cavity, the component is partially or completely opposite to the metal strip line, a projection of a part of the component that is opposite to the metal strip line is located on the metal strip line, and the component is configured to be movable to tune input impedance of the phase shifter;

wherein:
the component comprises a metal sheet, and the metal sheet is spaced from the metal strip line; or
the component comprises a dielectric slab, and the dielectric slab at least partially covers the metal strip line or is spaced from the metal strip line;

wherein a hole extends in a sidewall of the cavity, a first end of the physical connector is connected to the component, and a second end of the physical connector is opposite to the first end and is located in the hole; and
wherein the second end of the physical connector is configured to move in a length direction of the hole, to drive the component to move relative to the metal strip line, and the physical connector is configured to fasten the component to the cavity after the second end of the physical connector is moved in the length direction of the hole.
