Abstract

The invention discloses a mobile terminal with MIMO (Multi-input Multi-output) antennae. The mobile terminal comprises a medium base plate, a first circuit part and a second circuit part, wherein the first circuit part and the second circuit par are respectively arranged on the front face and the back face of the media base plate. The mobile terminal further comprises five antennae arranged on the front face of the media base plate, wherein the five antennae are distributed at the periphery of the first circuit part, and the five antennae are respectively connected with the first circuit part or the second circuit part by transmission lines; the directions of polarization of each two adjacent antennae are respectively orthogonal to each other; a first shielding cover is arranged on the first circuit part, a second shielding cover is arranged on the second circuit part, and the first shielding cover and the second shielding cover are grounded; and an air gap is reserved between each two adjacent antennae on the medium base plate respectively. By carrying out the technical scheme in the invention, under the condition that the volume of the mobile terminal is limited, the isolation between antennae is improved, thus the correlativity coefficient and the coupling coefficient of the MIMO antennae are greatly reduced, and the radiation characteristic of an MIMO antenna array is enhanced.

Description

technical field [0001] The present invention relates to the field of wireless communication, in particular to a mobile terminal with MIMO antenna. Background technique [0002] With the rapid development of wireless communication technology, mobile users have higher and higher requirements for the capacity and quality of wireless communication. Due to the problems of multipath fading, spectrum congestion, and noise interference in the current wireless channel, the improvement of data rate is greatly affected. . In order to further increase the capacity of the system, people have proposed antenna diversity technology, and the further development of diversity technology has produced MIMO technology immediately. Multiple-Input Multiple-Output (MIMO) technology in mobile communication refers to the technology that uses multiple transmitting antennas and multiple receiving antennas for wireless transmission. The wireless communication system using this technology is called MIMO....
