Abstract

The present invention provides a power divider combiner, feed network and electric adjustable antenna, including: a power divider circuit and a combiner circuit; the power divider circuit includes a power divider circuit main body and multiple power divider circuit branches, and the power divider circuit main body includes At both ends, each branch of the power dividing circuit is respectively connected to the first end of the main body of the power dividing circuit; The two combined circuit branches correspond to different frequency bands; each combined circuit branch is composed of multiple microstrip lines with different widths. The power divider combiner, feed network and electric adjustment antenna provided by the present invention, when the signal is transmitted through the divider of the combiner circuit, impedance matching is performed with each microstrip line in the divider of the combiner circuit, and the power divider combiner The impedance of the device is kept within the deviation range of the standard impedance, so that the phenomenon of impedance mismatch can be avoided, the fluctuation of the standing wave ratio in the branch of the combining 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...
