Letter, frequency range is mainly 825-960MHz, 1710-1850MHz, 1920-2500MHz, and antenna for base station is extensive in China
Using.
Antenna for base station covers communication zone using phased-array type, and this requires its antennas to have broadband, can carry out phase
The characteristics of control battle array scans.
But such phased array needs multiple antenna for base station to carry out certain layout in reality, it is not only of high cost and account for
It is big with spatial area.
Utility model content
In view of the deficienciess of the prior art, and a kind of occupied space face small the purpose of this utility model is to provide size
Product ultra-wideband dual-linear polarization cross-shaped oscillator antenna small, at low cost.
To achieve the above object, the utility model provides following technical solution：A kind of ultra-wideband dual-linear polarization cross shakes
Sub-antenna, it is characterized in that：Including four be connected in crosswise oscillator body, feed tab, coaxial balun, be placed on outside coaxial balun
Support column and mounting base, the coaxial balun are made of core wire and outer conductor, and support column is placed on mounting base and consolidates respectively
Due to the bottom of four oscillator bodies, described outer conductor one end is placed on mounting base and is fixed on the bottom of the oscillator body of two of which
Portion, described core wire one end is placed on mounting base and the other end is connected across oscillator body with feed tab one end, and the feed tab is another
One end is connected with support column.
The utility model is further arranged to：The oscillator body length is 5 ~ 100mm, the height of coaxial balun is 10 ~
200mm, a diameter of 5 ~ 50mm of support column；Feed tab width is 5 ~ 50mm, and length is 5 ~ 50mm；The mounting base a diameter of 50
~200mm。
By using above-mentioned technical proposal, the antenna is using the dual-linear polarization antenna of the entire communications band of covering as battle array
Member, two kinds of linear polarized antennas are coplanar, ground structure design altogether, can generate the broad beam characteristic of the orthogonal dual-linear polarization of directional diagram
Antenna can be used for the antenna for base station array element of mobile communication system.It is of a smaller size, and only needs an independent peace
Holding position.Novel ultra-wideband dual-linear polarization cross-shaped oscillator antenna uses coplanar structure, compact-sized, has saved space.Have simultaneously
There is very wide frequency band, the antenna of the multiple frequency ranges in former base station can be substituted, therefore reduce antenna for base station quantity, decreases simultaneously
Cost payout.
Description of the drawings

501 other end of piece is connected with support column 201.
The utility model is further arranged to：101 length of oscillator body is 5 ~ 100mm, the height of coaxial balun is 10 ~
200mm, 201 a diameter of 5 ~ 50mm of support column；501 width of feed tab is 5 ~ 50mm, and length is 5 ~ 50mm；The mounting base
301 a diameter of 50 ~ 200mm.
Outer conductor 401 and support column 201, as short-circuit minor matters, are directly fixed on installation for fixing oscillator body 101
Bottom plate 301.
Feed tab 501 is bent using the sheet metal of stepped form.
Mounting base 301 is used for the installation of antenna, while as the reflecting plate of antenna.
Single linear polarized antenna include the opposite coaxial balun of the feed tab 501, one of two oscillator bodies 101, one and
One support column 201 supports one of oscillator body 101 as support element while a coaxial balun is as feed assembly,
Support column 201 supports another oscillator；Two linear polarized antennas are in orthogonal form, two pairs of antenna co-planar designs, and mounted on same
On one bottom plate, two kinds of linear polarized antennas are coplanar, ground structure designs altogether, can generate the wide wave of the orthogonal dual-linear polarization of directional diagram
Beam antenna, it is compact-sized in this way, space is saved, while there is very wide frequency band, the multiple frequency ranges in former base station can be substituted
Antenna, therefore reduce antenna for base station quantity.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, the skill of this field
Art personnel carry out common variations and alternatives within the scope of technical solutions of the utility model should be included in the guarantor of the utility model
It protects in range.
