US 2026/0269484 A1 · PHASE SHIFTER, ANTENNA, AND BASE STATION

Abstract

Embodiments of this application provide a phase shifter, an antenna, and a base station. The phase shifter includes a cavity and a stripline. The cavity includes a side plate and a plurality of partition plates. The plurality of partition plates are spaced apart on the side plate, and the plurality of partition plates and the side plate define at least one accommodating space. The stripline may include a feeding portion and an output portion, the feeding portion may be disposed in one or more accommodating spaces, a dielectric portion is disposed between the feeding portion and a partition plate corresponding to an accommodating space in which the feeding portion is located, the output portion is connected to the feeding portion and extends outside the accommodating space, and the output portion is configured to be connected to a radiating element of an antenna.
