Abstract

The invention discloses a miniaturized dual-band eight-unit MIMO terminal antenna suitable for 5G. The antenna comprises a dielectric substrate, two dielectric side plates and circuits printed on thesurfaces of the three dielectric plates. Feeders of eight antenna units are printed at the upper surface of the dielectric substrate of the antenna, and a metal floor is printed at the lower surface of the dielectric substrate of the antenna; four antenna units and three sets of decoupling structures distributed among the antenna units at intervals are printed at the inner side walls of the two dielectric side plates, each antenna unit is formed by a T-type feed branch and two grounding radiation patches, each grounding radiation patch is formed by a rectangular patch and a bent short-circuitwire, each decoupling structure is a short-circuit metal patch having three bent thin seams, and the antenna units pass through the floor through the feeding points located at the end portions of thefeeders to perform feed of a coaxial inner core. Through optimization design of the antenna units and the decoupling structures, the positions of the antenna units and the decoupling structures are reasonably arranged so that the antenna has the advantages of miniaturization, double frequency bands and high isolation among the antenna units and is suitable for a 5G terminal.

Description

technical field [0001] The invention relates to antenna design technology in the field of wireless communication, in particular to the design of a miniaturized dual-band eight-unit MIMO terminal antenna suitable for 5G. Background technique [0002] MIMO (Multiple-Input Multiple-Output) technology is a technology that can make full use of space resources, realize multiple transmission and multiple reception through multiple antennas, and double the frequency without increasing spectrum resources and antenna transmission power. System channel capacity for wireless technologies. Since the MIMO technology has the advantages of multiplying the throughput, transmission distance and spectrum utilization rate of the communication system, the MIMO technology plays a very important role in the field of wireless communication. [0003] At present, handheld terminals are developing towards miniaturization and wearable, which makes the insufficient space for antenna design more tense. ...
