Abstract

The invention provides a power division and combination device, a feed network and an electrically tunable antenna. The power dividing combiner comprises a power division circuit and a combination circuit, wherein the power division circuit comprises a power division circuit main body and a plurality of power division circuit branches, the power division circuit main body comprises two ends, and each power division circuit branch is connected with the first end of the power division circuit main body; the combination circuit comprises two combination circuit branches, and each combination circuit branch is connected with the second end of the power division circuit main body; the two combination circuit branches are respectively corresponding to different frequency bands; and each combination circuit branch is formed by connecting a plurality of microstrip lines with different widths. According to the power division and combination device, the feed network and the electrically tunable antenna provided by the invention, when the signal is transmitted through the branch circuits of the combination circuit, impedance matching is performed on the signal and each microstrip line in the branch circuit of the combination circuit, and the impedance of the power division and combination device is kept within the deviation range of standard impedance, so that the phenomenon of impedance mismatching can be avoided, the fluctuation of the standing-wave ratio in the branch circuits of the combination circuit can be reduced, and the stability of signal transmission can be improved.

Description

technical field [0001] The invention relates to the technical field of wireless communication, in particular to a power divider combiner, a feed network and an electric adjustable antenna. Background technique [0002] With the development of wireless communication technology, the sky space resources of base station iron towers are becoming increasingly tight, which promotes the development of antennas in the direction of miniaturization, integration, and multi-function (multi-band, multi-polarization, and multi-purpose). The power divider combiner is an important part in the antenna subsystem of the base station. Designing high-performance and miniaturized power dividers and combiners has become the focus of antenna technology research. [0003] In the existing high-performance and miniaturized power divider combiner, during the signal transmission process, with the change of the frequency point in the frequency band, the standing wave ratio of the power divider combiner f...
