Embodiment Construction

[0031] The details of the invention will be described in more detail below in conjunction with the accompanying drawings.

[0032] see figure 1 , a miniaturized medium phase shifter group, including a bottom plate 7, a cover plate 6, a dielectric block 1, a transmission line 5, a medium phase shifting fixed column 2, a tie rod 3, a tie rod support block 17, and a connection port 18. Among them, see figure 2 , the bottom plate 7 is a rectangular block. A groove is formed on the top of the base plate 7 . A partition is arranged in the groove of the bottom plate 7, and the groove of the bottom plate 7 is divided into more than two bottom plate cavities by the partition. A dielectric block 1 is provided in each bottom plate cavity.

[0033] see figure 1 , the opening of the bottom plate 7 is equipped with a cover plate 6 .

[0034] see figure 1 , 3 tie rod support blocks 17 are arranged on the top of the cover plate 6 . The tie rod support block 17 is arranged along the l...

Abstract

The invention provides a miniaturized dielectric phase shifter group and a feeding network of an antenna array. The miniaturized dielectric phase shifter group includes a bottom plate, a cover plate, a dielectric block, a transmission line, a dielectric phase-shifting fixed column, a pull rod, a pull rod support block, and a wiring port; The phase shifter group is equipped with 8 power splitters, 8 power splitter rings and 16 antennas; beneficial technical effects: the invention is suitable for low cross-modulation in the 1.8~2.7G frequency band, continuous phase, good linearity, shifting The phase range is large, and the structure of the invention is simple and easy to process.

Description

technical field [0001] The invention belongs to the technical field of radio frequency communication, and in particular relates to a miniaturized dielectric phase shifter group and a feeding network of an antenna array. Background technique [0002] In densely populated urban areas, in order to achieve good coverage, electronically adjustable smart antennas are needed. As a key component of electronically adjustable antennas, the phase shifter is used to adjust the phase of the antenna elements in the array antenna to achieve the main beam. Scanning within a certain range means achieving different downtilt angles, thereby covering cells of different areas and reducing interference to adjacent cells. At present, the 3G network has covered a large area. In December 2013, the Ministry of Industry and Information Technology issued a 4G license. Domestic operators are planning to fully cover the 4G network. At present, most 4G antennas are prefabricated downtilt base station ante...
