The present invention relates to a mobile terminal technology, and in particular to a communication device of a mobile terminal and a mobile terminal.
MIMO (Multiple Input Multiple Output) system is a core technology used in 802.11n. 802.11n is a whole new wireless LAN technology following 802.11b\a\g by IEEE (Institute of Electrical and Electronic Engineers), reaching speeds of up to 600 Mbps.
It is more prevalent that modules are used in products. Moreover, there are already approaches that integrate a main antenna in a module. However, in fact, many products need to be compatible with a lot of bands, so performance requirements of the antenna are higher. In order to enhance signals, it not only needs the main antenna but also needs a sub-antenna. Ordinary 4G (Generation) antenna employs a single-board design. The main antenna and the sub-antenna are coupled to a mainboard through coaxial cables. Due to a restricted space, the two antennas interfere with each other because they are too close to each other, the performance being below standard.

The embodiment provides a communication device of a mobile terminal and a mobile terminal. As shown in
Since the main antenna 300 and the MIMO antenna 400 are separately disposed, their interference during sending and receiving information can be reduced, and the overlapping disposal of the main antenna 300 and the MIMO antenna 400 can be avoided, and the thickness of the mobile terminal can be reduced. The MIMO antenna 410 is coupled to the communication module 200 via the coaxial cable 410, so the MIMO antenna 400 can be freely adjusted and disposed anywhere within the mobile terminal, and the internal space of the mobile terminal can get a most optimal utilization. The linkage between the coaxial cable 410 and the communication module 200 employs the removable MIMO board 420 to connect to the spring contact plate 430. Accordingly, free swapping of the communication module 200 is realized. Users can increase or decrease Internet access capability at any time as desired, and can adapt the swap between a 3G (Generation) communication module and a 4G (Generation) communication module. The MIMO antenna 400 is a 4G antenna, which can also meet 3G spectrum requirements.
Said MIMO antenna 400 is a MIMO antenna, i.e. MIMO (Multiple Input Multiple Output) antenna. MIMO technology can exponentially increase a capacity of a communication system and spectrum utilization without increasing bandwidth.
