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： The present invention relates to the field of communications technologies, and discloses a combined phase shifter and a multi-band antenna network system. The combined phase shifter includes at least two laminated phase shifters, and different phase shifters have different frequency bands. Each phase shifter includes a signal layer and components that are slidable relative to the signal layer and that are configured to change a phase of an output port of the signal layer. A filter circuit is provided at the output port of the signal layer. Output ports of filter circuits corresponding to the at least two phase shifters are connected by using a conductor, and perform output by using a common output port. In the technical solutions of the present invention, output ports of two phase shifters having different frequencies are integrated by using a conductor to perform output. In comparison with the prior art, a quantity of cables used in a multi-band antenna network system is reduced. This facilitates a layout, thereby making it convenient to dispose the multi-band antenna network system. In addition, this facilitates a layout of an entire machine, reduces a weight of the entire machine, and reduces costs. In addition, the combined phase shifter provided in this embodiment of the present invention may also increase antenna gain, and optimize pattern parameters.

摘要： This application provides an antenna and a communication device, and relates to the field of communication technologies, to resolve a technical problem that a large quantity of antenna cables and solder joints are used, which is not conducive to reducing an antenna weight and improving antenna performance. The antenna provided in this application includes a reflective plate, a mounting bracket, a feed network, and a radiating element. The reflective plate has a reflective surface. The mounting bracket is disposed on one side of the reflective surface, and the mounting bracket and the reflective surface form a cavity facing toward an exposure in a first direction. The feed network is disposed in the cavity. The feed network has a feed point, and a projection of the feed point is located in the exposure. The radiating element is disposed on the side of the reflective surface. A projection of the radiating element on the mounting bracket is located in the exposure, and the radiating element is coupled to the feed point. In the antenna provided in this application, the feed network and the radiating element are disposed on a same side of the reflective surface. Therefore, the feed network may feed the radiating element in a coupling manner, so that material usage and an overall weight of the antenna can be reduced. This is conducive to improving communication quality of the antenna.
