The capacity of system, 4G LTE（Long Term Evolution, Long Term Evolution）The multi input that technology is employed in mobile communication is more
Output (Multiple-Input Multiple-Output, MIMO）Technology.MIMO technology refer to using many transmitting antennas and
The technology are wirelessly transferred by many reception antennas, it is desirable to which every antenna has good performance, the interference between adjacent antenna
Property is little.
At present, 4G data terminals volume is less and less, and existing antenna is difficult to realize the low correlation system between many antennas
Number and high-isolation, so data terminal or many configuration modes using single antenna, so effectively can neither realize
MIMO technology feature, can not preferably play the receptivity of 4G efficient movement of data terminals.
3rd, content of the invention
It is an object of the invention to provide a kind of can preferably play 4G efficient movement of data ends under limited volume
The receptivity at end, the 4G data terminal multi-input/output antenna devices with low correlation coefficient and high-isolation.
The technical solution for realizing the object of the invention is：A kind of 4G data terminals multi-input/output antenna device, bag
Circuit substrate is included, multiple antenna elements are set on circuit substrate, it is characterised in that the antenna element is arranged on circuit substrate side
In emargination groove, feed point connection of each antenna element by flexible transmission line corresponding thereto；It is additionally provided with circuit substrate
Rotary shaft, the antenna element are flexibly connected with rotary shaft and rotatable, and the distance for leaving feed point can telescopic variation as needed.
Polymer ceramic material of the antenna element using dielectric constant between 20 ~ 120 makes, in identical frequency
In the range of antenna size can reduce.
The antenna element can pass through rotation, telescopic variation, antenna is recovered in data terminal interior groove when idle.
The antenna element can pass through rotation, adjust polarised direction, coordinate telescopic variation, improve isolation between antennae.
Compared with prior art, its remarkable advantage is the present invention：1st, antenna is made using polymer ceramic material, reduces day
Linear dimension, can overcome the restriction of data terminal limited bulk, arrange multiple antennas；2nd, rotatable, stretchable dwi hastasana is adopted
Formula, it is easy to accomplish low correlation coefficient and high-isolation between antenna；3rd, simple structure, convenient for installation and maintenance, low cost, to environment
Pollution-free.
