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.
