Fig. 2 is the structural representation of the local antenna of embodiment according to the present invention and the minor matters being set on circuit board
Figure.
Specific embodiment
Hereinafter, with reference to the accompanying drawings to detailed description of the present invention embodiment.However, it is possible to come in many different forms real
The present invention is applied, and the present invention should not be construed as limited to the specific embodiment illustrated here.On the contrary, providing these implementations
Example is in order to explain the principle of the present invention and its practical application, so that others skilled in the art are it will be appreciated that of the invention
Various embodiments and the various modifications for being suitable for specific intended application.Identical label can be used in the whole instruction and attached drawing
Indicate identical element.
Fig. 1 is the front view of the antenna structure of embodiment according to the present invention.Fig. 2 is embodiment according to the present invention part
The structural schematic diagram of antenna and the minor matters being set on circuit board.It should be noted that antenna structure of the invention can be used for
In the mobile terminals such as smart phone, tablet computer.
Referring to Figures 1 and 2, the antenna structure of embodiment according to the present invention includes: antenna holder 10 and is set to day
Antenna 20 on line bracket 10.Antenna 20 includes spaced first antenna main body 21, the second antenna body 22, by first day
First antenna grounding leg 23 that one end of line main body 21 extends to form, second extended to form by one end of the second antenna body 22
Antenna ground foot 24 and antenna feed foot 25.Wherein, the first antenna main body 21 primarily serves coupling, and described second day
Feed effect mainly occurs for line main body 22.
In the present embodiment, first antenna grounding leg 23 and the second antenna ground foot 24, antenna feed foot 25 are separately positioned,
Second antenna ground foot 24 and the antenna feed connection setting of foot 25；But the present invention is not restricted to this.In addition, antenna feeds foot 25
Between first antenna grounding leg 23 and the second antenna ground foot 24, but the present invention is not restricted to this.
In the present embodiment, first antenna main body 21 and the side where the second antenna body 22 on given antenna bracket 10
For first side 101, that is, the front of the antenna holder 10；Then the first antenna grounding leg 23, the second antenna ground
Foot 24 and antenna feed foot 25 are set on the back side of first antenna main body 21 and the second antenna body 22.Here, by independent
Second antenna ground foot 24 is drawn minor matters 241 and is extended on circuit board 11.
It should be noted that in the present embodiment, first antenna main body 21, the second antenna body 22 and circuit board is extended to
On minor matters 241 between have certain antenna headroom height.When first antenna main body 21, the free height of the second antenna body 22
Degree reduce when, first antenna main body 21, the second antenna body 22 and minor matters spacing close to, formed coupling effect.
Since draw minor matters 241 is that the second antenna connecting with the second antenna body 22 feeds foot 24, the second antenna master
Body 22 primarily serves feed effect.Therefore, it can be formed at minor matters when first antenna main body 21, the work of the second antenna body 22
Resonance.
In Fig. 2, first antenna grounding leg 23 is set to the left side of the antenna feed foot 25, the second antenna ground foot 24
It is set to the right side of the antenna feed foot 25.
Preferably, in this embodiment, the minor matters 241 around circuit board 11 edge cabling, including the first minor matters main body and
Second minor matters main body.Wherein, the first minor matters main body is drawn from the lower section of the second feedback ground shell foot 24, around the first antenna grounding leg
23, the top cabling of the second antenna ground foot 24, antenna feed foot 25.This cabling is beneficial in that minor matters 241 can
Effectively far from other components on circuit board, avoid having an impact between antenna and component.Further, the second antenna master
Body is two continuous bending structures.
Specifically, the surface layer that the minor matters 241 are contacted with circuit board 11 is dielectric layer 12, is equally avoided that antenna and circuit
Other components on plate influence each other.
The present invention is not restricted the position of the minor matters, size, under different antenna environments, the position of minor matters, ruler
It is very little resonance frequency all to be had an impact, and to a certain extent, minor matters are shorter, and resonance frequency is higher.Therefore, in practical application
In, minor matters need according to circumstances specific debugging.
In conclusion and adjusting minor matters according to an embodiment of the invention, draw minor matters by the specific ground connection shell foot of antenna
Positions and dimensions make to form resonance at minor matters when Antenna Operation, can play optimization antenna high frequency bandwidth and improve antenna effect
The effect of rate.In addition to this, antenna structure volume of the invention miniaturization, structure is simple, easily modulates, processing cost is low, can
It is widely used on mobile terminal.
Although the present invention has shown and described referring to specific embodiment, it should be appreciated by those skilled in the art that:
In the case where not departing from the spirit and scope of the present invention being defined by the claims and their equivalents, can carry out herein form and
Various change in details.
