Technical field
This utility model relates to a kind of antenna, especially a kind of all-around top absorbing antenna.
Background technology
Indoor ceiling aerial is widely used in indoor mobile network and covers, the circularity of its antenna pattern, voltage standing wave ratio
Affected the biggest by assembly precision with third order intermodulation index.One passband of like product third order intermodulation at present is the lowest, reach-
Take in 107dBm (@33dBm) industry is all with RG141 or SFT type semi-rigid cable, and cost is the highest.
Utility model content
In order to solve the deficiency that prior art exists, this utility model provides a kind of low cost, indoor easy to process
All-around top absorbing antenna.
A kind of indoor all-around top absorbing antenna in this utility model, including radiating doublet, reflecting plate, coaxial cable, support
Post and insulation spacer；Radiating doublet is cup-shaped, and top is cylindrical, and bottom is taper；Coaxial cable includes that the cable of outer layer is exhausted
Edge layer and wire, wire is welded on radiating doublet bottom by scolding tin after the circular hole at reflecting plate center；Reflecting plate and radiation
Being provided with insulation spacer between oscillator, insulation spacer is avoided bottom radiating doublet, wire contacts with reflecting plate, support column top and spoke
Penetrate oscillator top be connected, bottom be connected with reflecting plate, reflecting plate is that conductive material is made；Insulation spacer center is provided with through hole, the end
Portion is that plane, top are provided with and the V-type opening coordinated bottom radiating doublet.Support column, by radiating doublet ground connection, forms signal and returns
Road；By V-type opening, radiating doublet is positioned, accurate positioning, it is to avoid the antenna performance that rigging error causes is inconsistent.Logical
Crossing this design to improve, make distributing point process consistency improve, the intermodulation index request of-107dBm@2*33dBm is in batch production
Time need not by using expensive SFT type or RG141 semi-rigid coaxial cable, and only need to use lower-cost RG-58,
RG-58U, SYV-50-3 or SYWV-50-3 Common radio frequency coaxial cable and common kirsite copper N-K joint can also reach intermodulation
Technological requirement.
As preferably, insulation spacer is that PTFE makes.PTFE full name is Polytetrafluoroethylene, polytetrafluoro
Ethylene, meets antenna dielectric properties requirement, and signal transmission effect is good.

Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail, but this should be interpreted as of the present utility model
The scope of above-mentioned theme is only limitted to above-described embodiment.
As Figure 1-3, a kind of indoor all-around top absorbing antenna, including radiating doublet 1, reflecting plate 2, coaxial cable, support
Post 6 and insulation spacer 5；Radiating doublet 1 is cup-shaped, and top is cylindrical, and bottom is taper；Coaxial cable includes the cable of outer layer
Insulating barrier 3 and wire 4, wire 4 is welded on radiating doublet 1 bottom by scolding tin 7 after the circular hole at reflecting plate 2 center；Reflection
Being provided with insulation spacer 5 between plate 2 and radiating doublet 1, insulation spacer 5 is avoided bottom radiating doublet 1, wire 4 connects with reflecting plate 2
Touching, support column 6 top is connected with radiating doublet 1 top, bottom is connected with reflecting plate 2, and reflecting plate 2 is made for conductive material；Absolutely
Edge pad 5 center is provided with through hole, bottom is plane, top is provided with and the V-type opening coordinated bottom radiating doublet 1.Support column 6 will
Radiating doublet 1 ground connection, forms signal circuit；By V-type opening, radiating doublet 1 is positioned, accurate positioning, it is to avoid assembling is by mistake
The antenna performance that difference causes is inconsistent.Improved by this design, make distributing point process consistency improve ,-107dBm@2*33dBm
Intermodulation index request need not when batch production by using expensive SFT type or RG141 semi-rigid coaxial cable, and
Only need to use lower-cost RG-58, RG-58U, SYV-50-3 or SYWV-50-3 Common radio frequency coaxial cable and common zinc to close
Gold copper N-K joint can also reach intermodulation technological requirement.
As preferably, insulation spacer 5 is made for PC.Low cost, it is simple to processing.
As preferably, the cross section angle of described V-type opening is 120 ~ 150.Fixing reliable, easy to process.
As preferably, described support column 6 is 3.Good fixing effect, easy to process.
