Problems solved by technology

However, the size of the antenna required by this method is large, and it is difficult to realize the integration and miniaturization of the MIMO antenna system.
[0007] The above-mentioned existing technologies either cannot realize a compact MIMO system, or have a relatively complex decoupling structure, or have great application limitations, or have a large antenna size

Abstract

The invention discloses a compact MIMO antenna system based on a connecting line. The system comprises a grounding plate, a first antenna, a second antenna, and a connecting line arranged outside thefirst antenna and the second antenna. The tail end of the outer side of the first antenna and the tail end of the outer side of the second antenna are connected with the grounding plate, one tail endof the connecting wire is connected with the non-tail end of the first antenna, and the other tail end of the connecting wire is connected with the non-tail end of the second antenna. The compact MIMOantenna system based on the connecting line has the advantages of being compact in antenna structure, small in antenna unit size, short in unit distance and the like, high integration, high compactness and high isolation are achieved, and the compact MIMO antenna system is compatible with MIMO antenna systems of various antenna types. The method can be applied to various wireless communication equipment, and is especially suitable for application of large-scale arrays in terminal equipment.

Description

technical field [0001] The invention relates to the technical field of communication antennas, and specifically proposes a connection line-based compact MIMO antenna system decoupling technology, which can be used for various wireless communication devices. Background technique [0002] Antennas have become an essential device in various wireless devices to transmit and receive electromagnetic wave signals. MIMO (Multiple-Input Multiple-Output) technology uses multiple antenna devices to transmit and receive at the same time, which can greatly increase the wireless transmission rate without increasing the transmission power or operating spectrum. It is the core technology of the fourth-generation mobile communication and fifth-generation communication systems one. In order to ensure excellent MIMO characteristics, it is necessary to achieve high isolation or low coupling between antennas to reduce the correlation between antennas. However, due to the limited space of moder...
