Technical field
Radio-frequency antenna technical field is the utility model is related to, is pasted more particularly to a kind of new dualbeam directed radiation MIMO
Chip antenna and mobile terminal.
Background technology
Following MIMO (Mitiple-Input Mitiple-Output) antenna system will realize the more preferable superelevation of security
It is necessary to have advantages below for fast data transfer：Spatial resolution significantly improves, depth excavated space dimension resource；Narrower ripple
Beam, higher gain, smaller transmission power loss, stronger system rejection to disturbance ability.
At present, the multi-beam of mimo antenna each means that different mimo antenna units or mimo antenna submodule have difference
The directional beam in direction, by the beam forming network or phase-shifter or switch of radio frequency rear end, beam scanning is carried out, to expand
Effective overlay area of mimo antenna, but these methods are worthless for mobile terminal, because more using having
The antenna of individual high-gain wave beam as 5G mobile terminal mimo antennas element antenna, it is necessary to overcome beam forming network to be brought
The problem of.But beam forming network is overcome, it is necessary in element antenna while cover the area of space of multiple different directions,
Keep equal sky, when, frequency reusability and system capacity on the premise of, reasonably reduce the unit number of mimo antenna, reduce and be
The difficulty of system beam alignment, the design difficulty of 5G mobile terminal mimo antennas is reduced, in addition, also to reduce 5G mobile terminals MIMO
Due to the mutual coupling that space wave/near field is triggered between antenna element, decoupling difficulty is reduced.
On the other hand in a wireless communication system, antenna and bandpass filter are two Primary Components, their performances it is excellent
It is bad directly determine whole system can ability to communicate quality.Nowadays, the development of mobile terminal diversity and individuality formation, especially
In the development of convenient aspect of performance, promoting antenna and wave filter more tends to small-sized and Integrated design for it.By antenna and filtering
Device Integrated design not only saves match circuit part in traditional design, reduces system dimension, and have simultaneously into filter antenna
The high out-of-side rejection ability of antenna radiation characteristics and pass filter, the performance of wireless communication system is improved on the whole.
But in the prior art, the Integrated design of antenna and wave filter causes extra, it is necessary to introduce extra filter circuit
Insertion Loss, gain and the radiation efficiency of antenna can decrease.
As can be seen here, how to realize that synthesis improvement of the mimo antenna in terms of multi-beam and filtering is those skilled in the art
Urgent problem to be solved.
