Abstract

A 3D-MID technology array antenna includes a feed line dielectric substrate, A surface of one side of that dielectric substrate of the feed line is provided with a metal ground, At that other side ofthe dielectric substrate of the feed line, a plurality of isolation regions distribute in an array are formed around the dielectric substrate by the isolation strips, An antenna unit is arranged in the isolation area, the isolation strips of two adjacent antenna elements are composed of magneto-negative metamaterial elements, A magnetonegative metamaterial element consist of two square helical resonators in cascaded connection, A magnetic negative metamaterial unit consisting of two square helical resonators in cascaded connection is placed between two adjacent antenna units to act as an isolation strip, and the isolation degree is improved at the same time of decoupling. The invention achieves the purpose of decoupling by loading a magnetic negative metamaterial unit between the antenna units from the perspective of restraining mutual coupling.

Description

technical field [0001] The invention relates to the technical field of mobile communication base stations, in particular to a 3D-MID technology array antenna. Background technique [0002] With the improvement of the integration of electronic equipment, the volume of communication equipment is getting smaller and smaller. At this time, the electronic components are too large for the entire equipment, which requires reducing their size. However, reducing the size without significantly compromising the functionality and efficiency of electronic components is a daunting task. In this context, it is very important to realize the same type of 3D-MID (Three-dimensional Molded Interconnect Device) processing technology as the carrier through the innovation of laser three-dimensional precision processing technology. [0003] In a MIMO antenna system, the interaction between antenna elements is unavoidable, which often has a certain impact on the performance of the entire antenna sy...
