Abstract

A multi-input multi-output antenna system structure includes a substrate, a metal ground layer arranged on the substrate, a first antenna and a second antenna arranged on the substrate. The first antenna includes a first signal feed-in end and a slot opened on the metal ground layer, the slot divides the metal ground layer into a first metal ground layer and a second metal ground layer that are symmetrical to each other, and the first signal feed-in end is set in the slot, and connected with the first metal ground layer and the second metal ground layer. The second antenna includes a second signal feed end and a signal radiation end. The second signal feed end is arranged in the slot opposite to the first signal feed end and is electrically connected to each other. One end of the signal radiation part is connected to the second signal feed end. The feed-in end is connected, and the other end extends roughly along the opposite direction of the slot. The present invention generates two heterogeneous antenna radiation patterns by exciting the first antenna and the second antenna with current, and solves the technical problem that traditional antennas tend to generate mutual inductance coupling and reduce radiation efficiency.

Description

technical field [0001] The invention relates to an antenna structure, in particular to a multi-input multi-output antenna system structure. Background technique [0002] With the rapid development of the wireless communication industry, wireless communication systems have become ubiquitous in daily life, whether in business or at home, and are widely used in various communications such as transmission of voice and data. [0003] Multiple input and output (multiple-input multiple-output; MIMO) communication system uses multiple transmitting antennas and multiple receiving antennas as the transmission and reception of spatial multitasking data streams. Its data transmission rate is high and the probability of receiving dead angles is reduced. feature that improves the performance of the wireless connection between the transmitter and receiver. [0004] As far as the current general antenna design is concerned, most antenna architectures for MIMO systems are designed by combin...
