Abstract

An embodiment of the invention provides a path combiner comprising a medium substrate and at least two wave filters arranged on the medium substrate; each wave filter comprises an input end, an outputend, a main transmission line and a parallel connection stub line; each of input ends of all wave filters is used as an input end for the path combiner, output ends of all the wave filters are connected to form an output end of the path combiner, the main transmission line is electrically connected with the input ends of the wave filter and the output end of the wave filter, one end of the parallel connection stub line is electrically connected with the main transmission line while the other end is open, the main transmission line of each wave filter and the parallel connection stub line matched with the same in use are distributed on different circuit layers, path combiner miniaturization is realized, and requirements for integration of the path combiner with other communication parts can be met. The embodiment of the invention also provides a phase shifter assembly and an antenna; when the path combiner is applied to the parts, the parts can be greatly downsized.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a combiner, a corresponding phase shifter component and an antenna. Background technique [0002] With the development of mobile communications, multi-frequency antennas play an increasingly important role in network coverage. In order to facilitate the layout or reduce the size of multi-frequency antennas, it has become a trend to integrate combiners and phase shifters. [0003] The combiner is generally used at the transmitting end. Its function is to combine two or more radio frequency signals from different transmitters into one and send it to the radio frequency device for antenna transmission, and at the same time avoid the mutual influence between the signals of each port. The performance of the combiner may affect the operation quality of the entire system, and the size of the combiner will affect the integration of components. Therefore, the miniaturization...
