2G, 3G, 4G communication service are provided, and this three generations's communication system is by long-term co-existence.But existing antenna system often only
The signal covering of certain operator's standard can be realized, it is impossible to realize that full frequency band full system type pictorial signal is covered, and site resource is gradually dilute
Lack so that the wideband antenna system demand that can provide service simultaneously for multisystem is constantly increased.Especially for mobile vehicle
Application scenarios for, not only require nothing more than the covering that antenna possesses full frequency band, full system type pictorial, also require that antenna has certain aesthetic property
With preferable disguise, and existing ripe antenna for base station is often even using crossed dipoles, electromagnetic dipole, differential feed
The extremely technical scheme such as son, these technical schemes require that oscillator has a quarter-wave spacing between bottom plate, therefore for
Low frequency standard such as CDMA（824~882MHz）, the section physical size of antenna is excessive, it is difficult to which the installation suitable for mobile vehicle is needed
Ask.In addition, interfering with each other between how overcoming each standard signal of each frequency range, is the problem of wideband antenna system has to be solved.
Utility model content
Goal of the invention：To solve above-mentioned technical problem, the utility model, which provides one kind, can cover existing shifting
7 standard low section full system type pictorial antenna systems of dynamic communication, antenna section size is low and can realize between each standard signal of each frequency range
Good isolation, be particularly suitable for use in the application scenarios of mobile base station.
Technical scheme：In order to solve the above technical problems, the utility model provides following technical scheme：A kind of low section is complete
Standard antenna system, including antenna plate, multiplefrequency mixer and active circuit, the antenna plate are provided with least two groups end-on-fire antenna,
There is more than 30dB isolation between the end-on-fire antenna；The antenna plate is connected by radio-frequency cable with multiplefrequency mixer, institute
Multiplefrequency mixer is stated to be connected with active circuit.
Preferably, the end-on-fire antenna is single broadband end-on-fire antenna.
Preferably, the antenna plate includes two width low frequency end-on-fire antenna and two panel height frequency end-on-fire antenna, described low
Frequency end-on-fire antenna works in 80~960MHz, and the high frequency end-fire Antenna Operation is in 1700~2700MHz.
Preferably, two width low frequency end-on-fire antenna are located at both sides, and two panel height frequency end-on-fire antenna are located at low frequency end-fire day
In the middle of line.
Preferably, the multiplefrequency mixer uses the multiplefrequency mixer of filter with low insertion loss high isolation.
Beneficial effect：Compared with prior art, the utility model has advantages below：1st, the low section in the utility model
Antenna system uses single broadband end-on-fire antenna scheme, and antenna can cover all 7 kinds of standards of mobile communication simultaneously；2nd, this reality
With low profile antenna system of the property in new, antenna section is highly less than 0.15 free space wavelength（Lower side frequency）, and conventional aerial
Scheme ratio, section height reduction half or so；3rd, the low profile antenna system in the utility model is due to optimizing antenna arrangement simultaneously
Using filter with low insertion loss high isolation multiplefrequency mixer so that good isolation is realized between each each standard signal of frequency range, it is to avoid mutual interference.
Brief description of the drawings
Fig. 1 is the theory structure schematic diagram of low section full system type pictorial antenna system described in the utility model.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated.
As shown in figure 1, low section full system type pictorial antenna system of the present utility model mainly include antenna plate, multiplefrequency mixer and
Active circuit, wherein antenna element are processed using copper-clad plate printing technology, and are fixed on plastic floor, two groups of low frequencies day
Line is respectively placed in the both sides of plastic bottom board, and high frequency antenna is placed in the centre of plastic bottom board, passes through space isolation and/or polarization isolation
To ensure there are enough isolations between common-frequency aerial.
Compared with conventional broadside antenna array, the utility model antenna uses broadband end-on-fire antenna, broadband end-on-fire antenna
Impedance matching property is influenceed low by section height, and section height only influences the elevation angle of antenna beam, before system requirements is met
Antenna installation height can be forced down as far as possible by putting.Therefore, end-on-fire antenna can realize good impedance matching in broadband
And directed radiation, it is possible to achieve the covering of full system type pictorial, battle array need not be organized because antenna gain is higher, in addition, end-on-fire antenna need not connect
Floor, therefore can effectively reduce antenna section height.The output signal of antenna sends into filter with low insertion loss high isolation by radio-frequency cable
Spend after multiplefrequency mixer filtering, send into the active circuit of rear end（Active equipment）, multiplefrequency mixer can be realized each to each frequency range
The distribution of standard signal, port isolation reaches 95dB；Whole antenna system transmitting-receiving reciprocity, is noted earlier when working in emission mode
Inverse process.
Multiplefrequency mixer of the present utility model uses metallic cavity scheme, can not only ensure larger power capacity, also
The isolation of superelevation can be realized.The utility model multiplefrequency mixer sets 4 radio frequencies to make an excuse in antenna side, respectively 2 low
Frequency interface and two high frequency interfaces.Two low frequency bands correspond to 890~960MHz and 824~882MHz respectively；It is two high again and again
Section all corresponds to 1700~2700MHz, and is connected respectively with two groups of antennas in antenna plate by radio-frequency cable.On multiplefrequency mixer
Two low frequency interfaces with antenna two low frequency interfaces correspondence be connected.The other side of multiplefrequency mixer has 7 radio frequencies to connect
Mouthful, six kinds of communication standards of GSM, CDMA, DCS, WCDMA, TDS-CDMA, TD-LTE are corresponded to respectively, and wherein DCS is divided into two frequency ranges
Each one radio frequency interface of correspondence.This 7 radio frequency interfaces are then connected with the base station radio-frequency leading portion of follow-up different communication standard.
It is whole in order to ensure that multiplefrequency mixer has enough suppression in the frequency range of a certain standard to other standard frequency band signals
Individual multiplefrequency mixer is made up of 3 cavitys, and two LF communication standards GSM and CDMA constitute a cavity, high-frequency communication standard
In DCS1, TD-LTE and TDS-CDMA constitute a cavity, DCS2 and WCDMA constitute a cavity, and all cavitys are all used
Digit Control Machine Tool is processed to ensure machining accuracy.While in order to ensure that multiplefrequency mixer brings relatively low insertion loss, all cavitys
It is internal all to use silver plating process.
It should be understood that these embodiments are merely to illustrate the utility model rather than limit scope of the present utility model, readding
Read after the utility model, modification of the those skilled in the art to the various equivalent form of values of the present utility model falls within the application
Appended claims limited range.
