Abstract

The embodiment of the present invention discloses a communication terminal, which includes a multiple-input multiple-output antenna system, and the multiple-input multiple-output antenna system includes a first antenna module, a second antenna module, and a first grounding structure; the first antenna module includes a first The radiator and the second radiator, a first gap is opened between the first radiator and the second radiator; the second antenna module includes a third radiator and a fourth radiator, the second radiator and the third radiator connected, the first radiator is used to form a first MIMO antenna, the second radiator is used to form a GPS antenna, the third radiator is used to form a first low-frequency communication antenna, and the fourth radiator is used to form a second MIMO antenna; One end of a ground structure is connected to at least one of the second radiator and the third radiator, and the other end is connected to the ground plane of the communication terminal, for increasing the isolation between the first antenna module and the second antenna module. The communication terminal can effectively improve the isolation between antenna modules.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular to a communication terminal including a multiple-input multiple-output antenna system. Background technique [0002] With the development of mobile communication technology, the demand for Multi-input Multi-output (MIMO) antenna technology on terminals is getting higher and higher, and the number and frequency bands of MIMO antennas are also increasing. *2 antenna system has gradually developed into a 4*4 antenna system, which brings severe challenges to the antenna design of metal body terminals. Metal industrial design (Industrial Design, ID) terminals (such as mobile phones) generally require high structural compactness and metal proportion. After adding MIMO antennas, on the one hand, the space of the original communication antenna is compressed, and on the other hand, MIMO The frequency band of the antenna is often the same as the frequency band of the original c...
