Abstract

The invention provides a multi-polarized radiation oscillator and an antenna. The multi-polarized radiation oscillator comprises a radiation unit, a first group of polarization feed units and a secondgroup of polarization feed units. The radiation unit comprises a first group of polarization radiation units and a second group of polarization radiation units, which are mutually connected. Each group of polarization radiation units comprise two mutually-orthogonal polarization directions. Polarization electric field vector directions of two adjacent polarizations of the first group of polarization feed units and the second group of polarization feed units form a 45-degree included angle. The first group of polarization feed units are electric dipole units; and the second group of polarization radiation units are magnetic dipole units. The first group of polarization feed units feed the first group of polarization radiation units; and the second group of polarization feed units feed thesecond group of polarization radiation units. Since four polarizations share one radiation unit, and four linear polarizations are realized without combination of multiple oscillators, so that the multi-polarized radiation oscillator can enable antenna structure to be more compact, and size of the antenna is reduced.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a multi-polarization radiation oscillator and an antenna. Background technique [0002] With the increase of mobile communication network standards, base station antennas are required to support multiple communication systems. In order to save site and antenna resources, reduce the difficulty of property coordination, and reduce investment costs, multi-frequency antennas that can support multi-system communications have gradually become an operational The first choice for commercial construction network. At present, the main antennas used in mobile communication networks are ±45° polarization combination, horizontal polarization and vertical polarization combination. Dual-polarization or multi-polarization antennas can be used to improve channel capacity by using polarization diversity reception technology to prevent signal decline. [0003] Conventional base station comm...
