Abstract

The present invention provides a dielectric phase shifter and a base station antenna. The dielectric phase shifter includes: a cavity, a PCB substrate, a geared rod, a gear medium and a feeding network, the PCB substrate, the geared rod, the gear Both the medium and the feeding network are installed in the cavity; the plurality of phase-shifting medium sheets included in the gear medium are respectively connected symmetrically along the upper and lower surfaces of the PCB substrate, and the upper and lower surfaces of the PCB substrate are respectively provided with the The toothed pull rod is driven by the toothed pull rod to rotate the plurality of phase-shifting medium sheets, and the phase-shifting is realized in combination with the setting of the feeding network. The dielectric phase shifter and the base station antenna provided by the present invention can effectively reduce the area of ​​the phase-shifting dielectric sheet and the volume of the metal cavity through the highly integrated setting of the phase-shifting dielectric sheet, and reduce the stroke of the sliding rod, thereby realizing miniaturization and cost reduction. Purpose.

Description

technical field [0001] The present invention relates to the field of antenna technology, and in particular, to a medium phase shifter and a base station antenna. Background technique [0002] In the rapid development of mobile communication technology, large-scale array antennas have begun to be widely used, but the traditional mechanical downtilt fixed-tilt array antennas can no longer meet the current needs of base station antenna construction in complex scenarios. Compared with the conventional mechanical downtilt antenna, the antenna with an electronically adjustable downtilt angle can adapt to a wider range of environments and is more convenient. Therefore, the phase shifter, the key component of the ESC antenna, has become the key technology of the large-scale array antenna. Its structure size, space utilization, processing and installation difficulty all directly affect the size and index of the whole machine. [0003] In order to realize the downward tilt of the ESC...
