Abstract: The present disclosure relates to phase shifters, antennas, and base stations. One example phase shifter includes a cavity, a built-in printed circuit board (PCB), and a stress relief portion. The stress relief portion is connected to the PCB, and the stress relief portion is configured to reduce a stress generated due to different coefficients of thermal expansion (CTE) of the cavity and the PCB.

Abstract: The present disclosure relates to dual-band antennas and antenna arrays. One example dual-band antenna includes a first radiating element and a second radiating element that are disposed on a reflection plate. An operating frequency band of the first radiating element is a first frequency band, and an operating frequency band of the second radiating element is a second frequency band. A minimum frequency of the first frequency band is greater than a maximum frequency of the second frequency band. The first radiating element includes a first feeding apparatus and a first radiator unit, the first feeding apparatus includes a coupling structure coupled to the first radiator unit, and the first feeding apparatus is used for coupled feeding for the first radiator unit by using the coupling structure.
