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 and is configured to change a relative dielectric constant near the first conductor section in order to increase an electrical length of 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.

Description

technical field [0001] Embodiments of the present invention relate to the field of antennas, and in particular to a phase shifting device and an antenna system for its application. Background technique [0002] The phase shifter is the core component of the electrical adjustment base station antenna system, and it plays a major role in the electrical adjustment of the antenna system's pattern. The phase shifter realizes the electrical adjustment of the antenna system pattern by changing the phase of the signal reaching the antenna system unit, and achieves the purpose of remote control and adjustment of the network coverage area under different circumstances. In the process of realizing the present invention, the inventor found that the size of the existing phase shifter is large, which does not conform to the current trend of miniaturization of antenna systems; in addition, the inventor also found that the power distribution characteristics of the existing phase shifter can...
