Abstract: A phase shifter, an antenna, and a base station are provided. The phase shifter in the present invention includes a feed unit, a tapping element, a conductor section, and a ground element, and the feed unit is electrically connected to the tapping element. The tapping element is electrically connected to the ground element when being shifted by a preset angle by using a port of the conductor section as a start position, so that a transmit signal is reflected to an input port of the feed unit, and whether a cable is correctly connected is determined according to the signal of the input port, thereby signal transmission accuracy of an antenna is ensured.

Abstract: Embodiments of the present invention disclose a phase shifting apparatus, including a first conductor section, a first tapping element, a feeder unit, and a dielectric element, where: the feeder unit is electrically connected to the first tapping element; the first tapping element is electrically connected to the first conductor section; the first tapping element is capable of moving along the first conductor section to change a phase of a signal that flows through the feeder unit, the first tapping element, and the first conductor section; and the dielectric element is disposed at a position near the first conductor section. With the phase shifting apparatus in the embodiments of the present invention, the dielectric element is disposed in order to increase an electrical length of a conductor, which correspondingly reduces a physical length of the conductor, so that the size of the phase shifting apparatus is reduced.
