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: This application provides an electronic component, capable of simplifying a structure of an electronic component. The electronic component includes a printed circuit board (PCB) and a cavity. An inner wall of the cavity is provided with at least one groove for fixing the PCB. A first groove in the at least one groove includes a first side wall and a second side wall. The first side wall and the second side wall form an opening of the first groove. A length of the first side wall in a first direction is greater than that of the second side wall. The first direction is parallel to a direction of the opening. The first side wall is provided with at least one first raised part. The first raised part protrudes from the first side wall to the second side wall along a second direction. The second direction is perpendicular to the first direction.

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.
