Abstract

The invention relates to a dual-polarized array antenna and a decoupling structure. The decoupling structure comprises a first resonance body and a second resonance body, wherein the first resonance body and the second resonance body are orthogonally arranged, the resonance frequency of the first resonance body is in a first preset frequency band, the resonance frequency of the second resonance body is in a second preset frequency band, and in the first preset frequency band and the second preset frequency band, one belongs to a low frequency band, and the other belongs to a high frequency band. During use, the decoupling structure can be arranged between two adjacent radiation units, the resonance frequency of the first resonance body is in the first preset frequency band, the resonance frequency of the second resonance body is in the second preset frequency band, and in the first preset frequency band and the second preset frequency band, one belongs to a low frequency band, and theother belongs to a high frequency band, so that spatial waves of the low frequency band and the high frequency band can be suppressed respectively, and the isolation degree can be improved.

Description

technical field [0001] The invention relates to the technical field of mobile communication, in particular to a dual-polarization array antenna and a decoupling structure. Background technique [0002] With the development of mobile communication technology, dual-polarized array antennas have been widely used in mobile communication networks due to their excellent performance. At the same time, in the case of tight antenna resources, choosing different working frequency bands reasonably can not only effectively use communication resources, but also save operation and maintenance costs. Therefore, in order to meet the market demand, the working frequency band of the traditional dual-polarized array antenna is usually very wide (1710MHz-2690MHz), which leads to poor isolation of the traditional dual-polarized array antenna. Contents of the invention [0003] Based on this, it is necessary to provide a dual-polarized array antenna and a decoupling structure for the problem o...
