Abstract: The application discloses an apparatus and a multi-band antenna network system. The apparatus includes at least two phase shifters. The phase shifters have different frequency bands. Each phase shifter includes a signal line layer and components that are configured to change a phase of an output port of the signal line layer. The components are slidable relative to the signal layer. A filter circuit is provided at an output port of the signal layer. Output ports of filter circuits corresponding to the at least two phase shifters are connected by a conductor, and perform output using a common output port.

Abstract: This disclosure provides an antenna. The antenna disclosure includes a reflective plate having a reflective surface, a mounting bracket, a feed network, and a radiating element. 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. By the provided antenna disclosure material usage and an overall weight of the antenna can be reduced. This is conducive to improving communication quality of the antenna.

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.

Abstract: The application discloses a combined phase shifter and a multi-band antenna network system. The combined phase shifter includes at least two phase shifters. The phase shifters have different frequency bands. Each phase shifter includes a signal line layer and components that are configured to change a phase of an output port of the signal line layer. The components are slidable relative to the signal layer. A filter circuit is provided at an output port of the signal layer. Output ports of filter circuits corresponding to the at least two phase shifters are connected by a conductor, and perform output using a common output port.
