Problems solved by technology

[0005] At present, the size of 4G data terminals is getting smaller and smaller, and it is difficult for existing antennas to achieve low correlation coefficient and high isolation between multiple antennas, so data terminals still mostly use a single antenna configuration, which is neither effective Realizing the characteristics of MIMO technology can not make better use of the receiving performance of 4G high-efficiency mobile data terminals

Abstract

The invention relates to a multi-input and multi-output antenna device for a 4G (fourth generation) data terminal. The multi-input and multi-output antenna device comprises a circuit substrate on which a plurality of antenna units are arranged. The multi-input and multi-output antenna device is characterized in that the antenna units are arranged into grooves in the edges of the circuit substrate, wherein each antenna unit is connected with a corresponding feed point through a flexible transmission line; a rotation shaft is arranged on the circuit substrate; the antenna units are movably connected with the rotation shaft and can make a rotating motion; and the distance of each antenna unit away from the feed point can be changed in a telescopic manner as required. According to the invention, the plurality of antenna units are arranged without being limited by the finite volume of the data terminal, and the antennas are rotational and telescopic, so that a low correlation coefficient and a high isolation degree can be realized among the antennas. Therefore, the receiving performance of the 4G high-performance mobile data terminal is exerted better. The multi-input and multi-output antenna device for the 4G data terminal has a simple structure and can be installed and maintained conveniently.

Description

[0001] 1. Technical field [0002] The invention relates to the technical field of communication antennas, in particular to a multiple-input multiple-output antenna device for a 4G data terminal. [0003] 2. Background technology [0004] With the rapid development of communication technology, 4G mobile communication technology adapted to mobile data, mobile computing and mobile multimedia information transmission has begun to rise. 4G technology has higher requirements for the capacity and quality of wireless communication. In order to further improve the capacity of the system, the 4G LTE (Long Term Evolution, Long Term Evolution) technology adopts the Multiple-Input Multiple-Output (MIMO) technology in mobile communication. MIMO technology refers to the technology of using multiple transmitting antennas and multiple receiving antennas for wireless transmission, requiring each antenna to have good performance and the interference between adjacent antennas is small.
