Abstract: This application provides a phase shifter and a remote electrical tilt antenna. The phase shifter includes a metal stripline, a first dielectric plate and a second dielectric plate. The metal stripline is clamped between the first dielectric plate and the second dielectric plate. At least one limiting protrusion protrudes along a length direction on a surface of the first dielectric plate and/or the second dielectric plate facing the metal stripline. The at least one limiting protrusion is configured to limit displacement of the first dielectric plate and the second dielectric plate relative to the metal stripline when the first dielectric plate and the second dielectric plate slide. The phase shifter provided in this application enables the first dielectric plate and/or the second dielectric plate to slide exactly along the length direction of the metal stripline without deviation, thereby realizing accurate control of a phase change by the phase shifter.

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.
