The size of 501 bearing of trend, first paragraph 500 and second segment 501 can using etc. lateral dimension structure.
After said structure, connect pin 50 first paragraph 500 can for radiation patch 30 and feeding network 51 it
Between connection transition is provided, in case electric current autoradiolysis paster 30 circulation area occur during being transferred to feeding network 51 violent
The situation of change, so that the transmission of electric current is more stablized, the isolation of antenna is lifted with this.
Further, groove 300 is opened up at the outer rim of radiation patch 30, the groove 300 is recessed to the middle part of radiation patch 30
Fall into, first paragraph 500 is connected in this groove 300.Specifically, groove 300 can use deep-slotted chip breaker, and the groove 300 can be the
One section of 500 offer installation space so that the development length of first paragraph 500 can suitably increase.This structure by first paragraph 500 with
The ledge structure that second segment 501 is formed, and groove 300 collective effect, further provide cushioning effect to the distribution of electric current,
Then the bandwidth and isolation of antenna are improved.
In a kind of embodiment, the cell wall of above-mentioned groove 300 includes the first plane, the second plane and the 3rd plane, and this first
Plane, the second plane and the 3rd plane are sequentially connected to form U-shaped structure, and connection pin 50 is connected in the second plane.Herein
Between first plane and the second plane, acute angle can be formed between the 3rd plane and the second plane, specific angle can be flexible
Selection.After groove 300 is using said structure, the distribution of electric current on the one hand can be made more regular, antenna is optimized with this
Performance；On the other hand the structure of groove 300 can be simplified, is easy to process the groove 300.

The distribution of electric current.
It is to be appreciated that set location of the first paragraph 500 in groove 300 can be partial to the side of groove 300, but this
Plant position still can produce influence to the distribution arrangement of electric current, cause the distribution situation of electric current not ideal enough.Therefore, in order that electric
The distribution of stream is more uniform and stable, and the distance between plane of first paragraph 500 and first is equal between the plane of first paragraph 501 and the 3rd
Distance.That is, first paragraph 500 is connected to the middle position of groove 300, and object defined above is reached with this.
When carrying out structure design, foregoing ledge structure can be type conical bench structure, but type conical bench structure processing
Technique is relatively complicated, causes to connect the bad control of machining accuracy of pin 50.Therefore, the ledge structure can be optimized for directly
Angle-style ledge structure, so as to simplify the processing technology of connection pin 50.
When evaluating the performance of antenna, the section height of antenna is an important index, and the section height is referred to
Size on antenna on the direction of itself extended surface.Wherein, the height dimension of radiation patch 30 and feeding network 51 will
The section height of antenna can be influenceed.In view of this, surface relative with second medium plate 20 in radiation patch 30 can be defined as
Fourth plane, the 5th plane is defined as by surface relative with second medium plate 20 on feeding network 51, and the fourth plane is prolonged
The extended surface for stretching face and the 5th plane is coplanar.Usually, the extended surface of the extended surface of fourth plane and the 5th plane is with
The surface of second medium plate 20 is parallel, therefore both extended surfaces are coplanar, you can to ensure this two extended surfaces and second medium
The distance between the surface of plate 20 is of substantially equal, and the section height of whole antenna is reduced with this.
Preferably, the direction of second medium plate 20, center and the parasitism of radiation patch 30 are pointed to along first medium plate 10
The distance between center of paster 40 is between 3mm~7mm, this numerical value can be fitted in the case where the performance of antenna is ensured
When the height of control antenna.Furthermore it is also possible to pass through to optimize the whole height of the height control antenna of support column 60, for example will branch
The height of dagger 60 elects 5mm or so as.
When the performance of antenna is evaluated, the degree of coupling between radiation patch 30 and parasitic patch 40 is also one important
Index, and the shape of radiation patch 30 and parasitic patch 40 can then influence this degree of coupling.In order to improve radiation patch 30 and post
The degree of coupling between raw paster 40, can be set to octagon paster by radiation patch 30, and parasitic patch 40 is provided in round
Paster.Now, the shape of radiation patch 30 is approximate with the shape matching of parasitic patch 40, then reaches object defined above.Separately, by spoke
Penetrate paster 30 and be set to octagon paster, be also convenient for realizing ± 45 ° of polarization of antenna.And parasitic patch 40 is provided in round patch
