Problems solved by technology

[0004] In order for a MIMO antenna system to have good performance, the antenna elements must be uncorrelated (low coupling), however, the space that can be reserved for antennas in mobile devices is very limited, making it impossible for the spatial distance between antennas to be greater than or equal to a wavelength

Abstract

The method is suitable for the technical field of 5G antenna interference prevention. The invention discloses a discrete 5G antenna isolation system, which comprises a step decoupling structure arranged between antennas, wherein the step decoupling structure comprises at least one upper micro-strip etched on the upper surface of a dielectric plate between the two antennas and at least one lower micro-strip etched on the lower surface of the dielectric plate between the two antennas, the upper micro-strip is electrically connected with the adjacent lower micro-strip through a metal via hole, and the upper micro-strip and the lower micro-strip which are connected through the same metal via hole are distributed in a staggered manner. The upper micro-strips and the lower micro-strips between the adjacent metal via holes are distributed in an up-and-down staggered manner, so that the current flowing path can be longer at the resonant frequency, the equivalent inductance is larger, the propagation path of a coupling field (or coupling current) between antennas can be blocked, and the decoupling effect between antenna arrays is realized. Simulation results show that good resonance stability can be ensured in different polarization modes, and the electrical size is reduced to 1 / 4 compared with the traditional electrical size.

Description

technical field [0001] The present invention relates to the technical field of 5G antenna isolation, in particular to a high isolation discrete 5G antenna isolation system suitable for data communication of miniaturized terminal equipment.
