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: This application relates to a phase shifter and a remote electrical tilt antenna including the foregoing phase shifter. The metal strip includes a cavity, a metal strip, a sliding dielectric, and a fastener, where the fastener fastens the metal strip in the cavity, so that a transmission portion of the metal strip is suspended in the cavity, requiring no metal strip to be disposed on a substrate, thereby reducing the signal energy loss of the substrate, decreasing the heat generated due to the signal energy loss, and lowering the requirements of the phase shifter on heat dissipation and temperature resistance of an internal mechanical part.

Abstract: An adapter device, a feeder device, and an antenna are provided. The adapter device includes a coaxial cable, an air dielectric microstrip, a ground plane, and a non-flat metal part. An outer conductor of the coaxial cable is electrically connected to the non-flat metal part, the non-flat metal part and the ground plane form non-flat capacitive coupling, and an inner conductor of the coaxial cable is electrically connected to the air dielectric microstrip. The outer conductor of the coaxial cable is grounded.
