Antenna and Phase Shifter

Abstract

The invention discloses an antenna and a phase shifter, comprising a first circuit layer, the first circuit layer is provided with an input branch and a first output branch, and the first output branch and the input branch are insulated; the second The circuit layer, the second circuit layer can move relative to the first circuit layer; and, when the second circuit layer moves to the first position relative to the first circuit layer, the first output branch is disconnected from the input branch; when the second circuit layer moves to the first position relative to the first circuit layer; When the second circuit layer moves to the second position relative to the first circuit layer, the first output branch is connected to the input branch; and a dielectric board, the dielectric board can move relative to the first circuit layer and can drive the second circuit layer Switch between the first position and the second position. The antenna adopts the aforementioned phase shifter to not only realize the adjustment of the electrical downtilt angle, but also realize the adjustment of the value of the beam width.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to an antenna and a phase shifter. Background technique [0002] With the development of mobile communications, it is an inevitable choice for operators to increase sites in order to meet coverage and capacity requirements. At present, after the large-scale construction of base stations, the in-depth coverage and blind-filling work in residential areas, commercial streets and other areas has become the focus of major operators. Adding traditional macro stations in these areas is costly and long-term. At the same time, the antenna size is large and site selection is difficult. Therefore, in traditional technologies, micro-site antennas or low-gain directional antennas are usually used for coverage or blind filling. [0003] However, in practical applications, some coverage scenarios need to adjust the value of the beam width to cover areas of different ranges. However, the va...

Problems solved by technology

However, the value of the vertical beam width of the micro-station antenna or other low-gain antenna is fixed, and the corresponding coverage area is also relatively fixed, so it cannot meet the requirements of practical applications.
