Abstract: A housing (1), an energy processing apparatus, and a base station antenna are provided. The housing (1) includes at least one accommodation cavity (15), the accommodation cavity (15) is for disposing a circuit board (2), side walls of the accommodation cavity (15) are provided with a plurality of through holes (11), and a total area of through holes (11) on any side wall of the accommodation cavity (15) is not less than ½ of an area of the side wall; and mounting holes are provided on the side wall of the accommodation cavity (15), and the mounting holes are used to allow the input port (3) and the output port (4) to pass through.

Abstract: This application provides a phase shifter. The phase shifter includes a phase shift assembly including a substrate, a rotating arm, a drive arm, and a drive assembly. An output line is disposed on the substrate, and the output line includes an arc-shaped segment. The rotating arm is rotatably connected to the substrate through a rotating shaft, a coupling line is disposed on the rotating arm, and the coupling line is electrically connected to the arc-shaped segment. One end of the drive arm is fastened to the rotating arm, and the other end extends to a side that is of the rotating shaft and that faces away from the output line, and is in transmission connection to the drive assembly. The drive assembly drives the drive arm to move, and the drive arm drives the rotating arm to rotate relative to the substrate.

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 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 disclosure relates to a component of a radio frequency functional device. The component can be a suspended strip line or any structure including the suspended strip line, which includes 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. The signal processing line has one end conducted to a signal source and another end electrically connected to the plurality of power branch lines separately. A 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.
