Abstract: An antenna includes a first signal cable, a second signal cable, a combiner, a combined transmission line, a plurality of first filters and a plurality of cavities. The first signal cable is configured to transmit a first signal. Output ends of the first signal cable and the second signal cable are connected to an input end of the combined transmission line through the combiner. The plurality of first filters are each electrically connected to the first signal cable and are respectively located in at least two different cavities of the plurality of cavities. The plurality of first filters are configured to filter a second signal thereby generating the first signal.

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: The present disclosure relates to feed structures of antennas, antennas, and communication devices. One example feed structure includes a first cavity with a first signal cable and a second cavity with a second signal cable. The first signal cable includes a first main part and a first elastic bending part located at one end of the first main part. The first main part extends along a first direction. An extension direction of the first elastic bending part intersects with the first direction, and the first elastic bending part can be deformed towards the extension direction of the first main part. A first hole is provided between the first cavity and the second cavity. The first cavity and the second cavity are connected through the first hole.

Abstract: An antenna assembly includes at least one element group, a switching assembly and a phase shifter. Each element group of the at least one element group includes at least one radiating element. The switching assembly is communicatively connected to the at least one element group, and is configured to control turning on or off of the at least one element group. The phase shifter is communicatively connected to the switching assembly, and is configured to perform beamforming on the antenna assembly. Roll angles of the antenna assembly are different in response to the switching assembly turning on different element groups of the at least one element group.
