摘要： 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.

摘要： This application relates to a suspended strip line, including a cavity and a strip line located in the cavity. The strip line includes a signal processing line, a plurality of power branch lines, and a connector. One end of the signal processing line is conducted to a signal source, and another end is electrically connected to the plurality of power branch lines separately. The plurality of power branch lines include a first power branch line. The first power branch line includes a first segment and a second segment that are disconnected from each other. One end of the first segment is electrically connected to the signal processing line. The second segment is located at one end of the first segment away from the signal processing line. The connector is located between the first segment and the second segment, to implement signal transmission between the first segment and the second segment. In this application, the suspended strip line is assembled by disconnecting the power branch lines and splicing the power branch lines through the connector. This reduces a length-width ratio of the strip line, thereby facilitating the fabrication and maintaining consistency of the strip line. Transportation and mounting costs of the strip line are also reduced. This application further relates to a phase shifter and a base station.

摘要： 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.
