Abstract

The invention discloses a high-isolation double-unit MIMO (multiple input multiple output) antenna array which is characterized in that: two independent resonant modes are produced through two C-like radiating units and two inverted-L-shaped radiating units printed on the front and back surfaces of a dielectric substrate, and used for controlling the double frequency characteristics of an antenna; and on the premise of realizing double-frequency coverage, a decoupling structure is formed on an additional floor unit printed on the front surface of the dielectric substrate and an isolation groove formed on a floor, so that the isolation between antenna units in a multi-frequency range is improved, and the bandwidth performance of dual-frequency operation is ensured.

Description

technical field [0001] The invention relates to a MIMO antenna, in particular to a high-isolation dual-element MIMO array antenna. Background technique [0002] The advent of the information age declares that the timely delivery of information, fast interaction, and effective transmission have become an indispensable part of our daily life and work. With the continuous development of various wireless communication services and broadband data services, more stringent requirements are placed on the high speed and effectiveness of data transmission. Various communication services are interleaved and parallel, and the occupation and competition of wireless resources make the current scarce spectrum resources more and more tense. How to use these limited communication resources more efficiently has become one of the urgent problems to be solved in wireless communication. Studies have shown that using MIMO (Multiple Input and Multiple Output), that is, multiple input and multiple...
