Embodiments of the present invention provide a phase shifter, antenna, and base station. The phase shifter in the present invention comprises: a feed unit, a tapping element, a conductor section, and a ground element. The feed unit is electrically connected to the tapping element. A port of the conductor section is an origin, and the tapping element is electrically connected to the ground element when being shifted by a predetermined angle, thereby reflecting a transmission signal to an input port of the feed unit, and determining, according to the signal at the input port, whether a cable is correctly connected. Embodiments of the present invention can ensure that a correct signal is transmitted by an antenna. |
