Description
Technical field
The utility model is related to a kind of mobile base station antenna technology, the base station day being multiplexed more particularly, to a kind of radiating element
Linear system is united.
Background technology
With the development of mobile communication technology, as the antenna for base station of wireless access system, substitute also with communication system
And improve, the performance of antenna system directly affects the overall performance of whole wireless network, at present, and many net operations have become operation
The theme of business's network Development, many nets gradually shown coexist scene and higher requirement are also proposed to antenna for base station, mobile logical
Letter occurred 2G 3G 4G coexistence of systems situation, for compatible a variety of communication standards, multifrequency dual polarized antenna is advised greatly
Mould is used.And with the problems such as the sharply increasing of base station number, the diminution of cellular cell radius, difficult new site addressing increasingly
Show, this requires antenna for base station to accelerate the evolution to multifrequency, miniaturization.
How arranged in an array multifrequency antenna of the prior art is, when number of arrays increase, directly spatially increases array
Arrangement, so directly results in antenna size and weight is multiplied.Antenna size and weight increase, install to tower on antenna and bring
It is greatly difficult, considerably increase the cost of operator；Simultaneously because antenna size increase, front face area directly increases, seriously
Reduce reliability of the antenna on tower.
Therefore supporting the miniature antenna of multisystem work just turns into the main development direction of antenna for base station.
Utility model content
The purpose of this utility model is the defect for overcoming prior art, it is proposed that a kind of size is small, lightweight, and cost is low
Miniaturization base station antenna system.
To achieve the above object, the utility model proposes following technical scheme：A kind of base station antenna system, including first day
Linear array and the second aerial array, the first antenna array include a plurality of first radiating elements, second aerial array
Including a plurality of second radiating elements, the first antenna array and the second aerial array are used to receive and send out in same frequency band
Signal is penetrated, at least one multiplex radiation unit is shared between the first antenna array and second aerial array.
Preferably, the first antenna array and the second aerial array are linear array.
Preferably, the antenna system also includes duplexer, and the duplexer is connected with the multiplex radiation unit, described
The first signal and the secondary signal separation of the second aerial array output that duplexer exports the first antenna array.
Preferably, the antenna system also includes third antenna array, the third antenna array and the first antenna
Array and/or the second aerial array share at least one multiplex radiation unit.
The utility model base station antenna system is applied to multi-frequency array antenna, when number of arrays increase, is not simply to exist
Spatially directly increase one or more arrays, but radiating element is shared with existing array, do not lose antenna performance
In the case of, keep antenna package size and weight to minimize, reduce tower is installed on antenna difficulty and cost, reduce meeting for antenna
Wind area, lifts reliability.

Embodiment
Below in conjunction with accompanying drawing of the present utility model, the technical scheme progress to the utility model embodiment is clear, complete
Description.
As shown in figure 1, the utility model antenna system 1 includes the aerial array 12 of first antenna array 11 and second, first
The aerial array 12 of aerial array 11 and second shares the multiplex radiation unit 10 of center section, and the multiplex radiation unit 10 is distinguished
Using the feeding network of high-isolation, multiplex radiation unit is set to be divided into two, the two-way branched away is directly mutually isolated, and is equivalent to
The radiating element of two groups of independence.Thus, the radiation gain of two arrays had both been can guarantee that, can make not interfereing with each other between two row again.Together
When antenna be directly superimposed with two arrays in length direction, size is directly reduced（Radiating element spacing * sharing unit numbers）, to day
The effect that linear dimension reduces is clearly.
Specifically, the first antenna array 11 includes a plurality of first radiating elements 111, second aerial array
12 include a plurality of first radiating elements 121, and the linearly arrangement of aerial array 12 of first antenna array 11 and second is formed
One linear array, is originally preferable to carry out being illustrated a kind of linear array, optionally or broken line array arrangement,
The aerial array 12 of first antenna array 11 and second is used to receive and transmission signal in same frequency band, the multiplex radiation
Unit 10 is arranged on the centre position of linear array, and the quantity of the multiplex radiation unit can be single or multiple.
As shown in Fig. 2 each multiplex radiation unit 10 is connected with a duplexer 20 respectively, the duplexer 20 is by signal
Separation, forms the two way feed signal 30,40 being mutually isolated, two paths of signals inputs the feeder network of two-way aerial array respectively,
Multiplex radiation unit is used so that antenna size diminishes, but does not influence the radiation gain of two arrays.
Above-described embodiment is the utility model preferred embodiment, as embodiment two, and the utility model also includes the 3rd day
Linear array, the third antenna array shares at least one multiplex radiation list with the first antenna array and the second aerial array
Member, now, third antenna array can be arranged on the linear array of the first antenna array and the formation of the second aerial array
Sidepiece.
In the present embodiment, the third antenna array can also be shared at least with first antenna array or the second aerial array
One multiplex radiation unit, now, diverse location of the multiplex radiation cell distribution in three column arrays.
The most direct effect of the utility model is exactly the effectively size and weight for reducing multifrequency antenna of energy, while can also
Ensure the isolation between different arrays, do not influence the radiance of antenna completely.The reduction of the size and weight of antenna, can be
Tower is installed and brought great convenience on antenna；Simultaneously for the performance requirement reduction of mounting bracket on mast, it can also save into
This.
Technology contents and technical characteristic of the present utility model are had revealed that as above, but those skilled in the art still may be used
A variety of replacements and modification without departing substantially from the utility model spirit can be made based on teaching of the present utility model and announcement, therefore, this
Utility model protection scope should be not limited to the content disclosed in embodiment, and should include various without departing substantially from replacement of the present utility model
And modification, and covered by present patent application claim.
