Description

Circular polarization aerial

Technical field

The utility model relates to a kind of circular polarization aerial, refers in particular to a kind of by the circular polarization aerial that attaches the plane copper foil conductor on an insulating concrete cylinder with a special angle.

Background technology

Circular polarization aerial at satellite communication, adopts the circular polarization aerial optimum because the circular polarization signal that it produced can be compatible with horizontal polarization signal or vertical signal; The frequency range that so is used for the antenna of Circular Polarisation signal is rather narrow, and antenna must be adjusted to required frequency individually, so it is restricted on using.

Along with the universalness that Wi-Fi city cloth is built, because the above-mentioned characteristic of circular polarization aerial, many electronic installations relevant with the networking line will all need be equiped with circular polarization aerial, so Related product certainly will get more and more.

The frequency range popularization and application of this kind circular polarization aerial at present is in the gps satellite positioning antenna, and present Circular Polarisation is used in the antenna of 2.4GHz frequency range, still is rare.This design but belong to the location and use in the vehicles of the vehicles in high-speed mobile during for example automobile, train etc. travel at a high speed, when the desire utilization is got online without being tethered to a cable, can not be subject to speed, and it is bad and can't enjoy the life of getting online without being tethered to a cable at any time to make it accept signal.

The utility model content

The utility model has the existing defective of technology at above-mentioned habit, and main purpose provides a kind of circular polarization aerial that is designed to the radiation frequency of various frequency ranges and receives signal with reception well.

For realizing above-mentioned purpose, the utility model is taked following technical scheme:

A kind of circular polarization aerial, comprise the cylinder that an insulating material is made, be pasted with many plane copper foil conductors along the cylinder periphery, these many plane copper foil conductors attach until this cylinder lower surface with helical form along this cylinder outer peripheral face with the direction attaching back that is perpendicular to one another from this cylinder upper surface center, and wherein each plane copper foil conductor direction that the upper surface attaching is extended at the bottom of cylinder just becomes 180 degree with it in cylinder lower surface attaching direction.

Adjacent two conductors that winding is pasted to the plane copper foil conductor of insulating concrete cylinder lower surface are and then do not connect between two conductors that the state of connecting and two continuous conductors link to each other with another and leave a gap.

This plane copper foil conductor be two and in cylinder bottom with the attaching that extends outwardly of right-angle crossing mode each other.

This plane copper foil conductor be four and link to each other each other with its initiating terminal from the center at the cylinder upper surface and the 90 degree modes that are mutually along the four direction attaching that extends outwardly.

The diameter of this insulating concrete cylinder is that 0.35-0.45 is than 1 to aspect ratio.This antenna frequency range is up to the frequency range of 6GHz.

Particular words it, when desiring to be designed to the 2.4GHz frequency range, the especially preferable diameter of this cylinder is 25mm and highly for 75mm, and the width of this plane Copper Foil is below the 3mm.

The insulating material of made cylinder can use various plastics materials, decides on required purposes, but is generally polyvinyl chloride or Merlon or PETG.

The utility model has technology to compare with habit, and its advantage is can be designed to the radiation frequency of various frequency ranges and receive signal well with reception, and it can emotionally still be able to good signal under the condition in high-speed row and receive various frequency ranges and especially receive the 2.4GHz frequency range.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is further specified.

Present embodiment is to be that example is illustrated with frequency range 2.4GHz, but this frequency range novel optimum frequency band that only is this does not mean the utility model and only is this frequency range.

At first see also Fig. 1 to Fig. 3, Fig. 1 looks perspective view on the utility model circular polarization aerial; Fig. 2 looks perspective view for the end of the utility model circular polarization aerial; Fig. 3 is the end TV structure schematic diagram of the utility model circular polarization aerial.

As shown in Figure 1, the utility model circular polarization aerial 1 is made of an insulating concrete cylinder 2 and the plane copper foil conductor 3 that is wound on these insulating cylinder body 2 outer peripheral faces 23, wherein this plane copper foil conductor 3 is made of the first Copper Foil conductor 31 and the second Copper Foil conductor 32, surperficial 21 centers attach with four orientation outwardly with the direction that is perpendicular to one another on this cylinder 2, attach along cylinder outer surface 23 subsequently, its winding angle is wound under the cylinder 2 at surperficial 22 o'clock for making, each plane copper foil conductor 3 the bearing of trend of upper surface 21 just be 180 degree at lower surface 22 bearing of trends; Configuration according to this is when one of first Copper Foil conductor 31 end 31 ' is that when it is wound to cylinder 2 lower surfaces 22, it will become the orientation, the southeast at Fig. 2 as the northwest position of Fig. 1 the time at cylinder 2 upper surfaces 21.

In addition, as shown in Figure 3, be pasted to lower surface 22 plane copper foil conductors and be the conductor that is adjacent one another are and be connected shape but this conductor adjacent one another are and do not link to each other and leave a gap 4 again with between conductor that another is connected to each other.Symbol "+" shown in Fig. 3 means the central point of this insulating concrete cylinder 2.

Though extend attaching in the center with mutual square crossing configuration in the cylinder upper surface with two plane copper foil conductors in the above-described embodiments, but in the utility model, also can utilize four plane copper foil conductors, being starting point from cylinder lower surface central point respectively, be connected to each other with starting point but extend the attaching that extends outwardly of direction that angle is 90 degree each other, each bar plane copper foil conductor is after being wound to the cylinder upper surface along the insulating concrete cylinder outer peripheral face simultaneously, and its orientation just transfers 180 degree to.

In the foregoing description, be the circular polarization aerial of 2.4GHz for receiving frequency range especially, the width of this plane copper foil conductor is preferably below the 3mm, the diameter of insulating concrete cylinder to aspect ratio be 0.35-0.45 than 1, better its diameter is 25mm and the high 75mm of being.

The above, it only is the preferred embodiment of the utility model circular polarization aerial, be not that technical scope of the present utility model is imposed any restrictions, so every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment did.
