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.
Claims9
A phase shifter, comprising a cavity and a built-in printed circuit board (PCB) in the cavity, wherein the phase shifter further comprises:
