AI Technical Summary

Problems solved by technology

The base station antenna units mostly adopt ±45° orthogonal polarization, and the beam width of the unit is the largest in the direction of ±45°, so the use of triangular layout has no obvious effect on improving the isolation of antenna units
Increasing the height of the isolation strips between the antenna elements can also reduce the mutual coupling strength, but if the height is too high, it will affect the beam shape of the antenna and deteriorate the cross-polarization level of the antenna

Abstract

The invention discloses an isolating bar for reducing antenna coupling energy. Decoupling gap units which are periodically arrayed and are capable of inhibiting coupling energy between two adjacent antenna units in an antenna array by means of the shape and size are machined on the isolating bar in the height direction. The invention further provides an antenna and an MIMO antenna. By means of the implement mode, coupling between the antenna units in the antenna working band can be reduced, and the isolation among the antenna units is improved; the isolating bar is easy to machine and low in cost and has remarkable effect.

Description

technical field [0001] The present invention relates to the technical field of mobile communication base stations, and in particular to an antenna, a MIMO antenna and an isolation bar for reducing mutual coupling energy of the antenna. Background technique [0002] The main design tasks for base station antennas are beamforming, multi-frequency operation, size reduction and designing antenna systems with advanced technologies. [0003] The currently developing 3D MIMO technology divides each unified vertical antenna element into multiple different elements, and uses the degree of freedom in the vertical direction to further reduce inter-cell interference and enhance antenna performance. In 3D MIMO base station antennas, beamforming and size reduction become the most important design tasks. Among them, the beamforming design is affected by the geometric layout of the array antenna, the element spacing, the pattern of each radiating element, and the excitation amplitude and p...
