Abstract
The invention discloses an antenna structure. The antenna structure comprises a vibrator, a short-circuit arm, a grounded metal sheet and a movable arm, wherein one end of the short-circuit arm is connected with the vibrator, and the short-circuit arm is provided with a first chute; one surface of the grounded metal sheet is connected with the other end of the short-circuit arm, and the grounded metal sheet is provided with a second chute; and the movable arm is arranged in the first chute and the second chute and slides in the chutes. The effective length of the antenna vibrator can be adjusted by using the antenna structure, namely regulate a resonant frequency point used by an antenna so as to meet the requirements under different conditions; and antennas of different resonant frequency points does not need reproducing so as to save the cost.
Description
[technical field]
The present invention relates to a kind of antenna structure, particularly a kind of antenna structure of scalable oscillator effective length.
[background technology]
It is fixed to use the WLAN antenna structure to be in the market, after the antenna moulding, the resonant frequency point of antenna is also fixing, if after loading onto board mechanism, be interfered, antenna produces frequency deviation, then can cause the decreased performance of wlan system, often need change antenna in such cases or repair a die again and revise antenna to reach best, this must cause production cost to promote.Existing antenna structure is as follows:
Fig. 1 illustrates the schematic diagram of existing antenna structure.
As shown in Figure 1, existing antenna structure comprises:
An oscillator 1;
A short circuit arm 2, the one end is connected with a surface of above-mentioned oscillator 1, and this short circuit arm 2 is provided with a coaxial line feedback point 21;
A grounded metal sheet 3, surface thereof is connected with the other end of above-mentioned short circuit arm 2, also is provided with a coaxial line earth point 31 on this grounded metal sheet 3.
In present embodiment, the length of short circuit arm 2 is fixed in the existing antenna structure, cause the effective length of oscillator 1 also to be fixed, and then the resonant frequency point of antenna is also fixed, when antenna is interfered, can cause the decreased performance of wlan system when producing frequency deviation, the antenna that also often occurs making simultaneously when research and development of products is failed to reach optimum efficiency in application and is caused producing again the antenna of different resonant frequency points, and then causes the cost waste.
In view of this, be necessary to propose a kind of antenna structure in fact, utilize this antenna structure can adjust the effective length of antenna oscillator, promptly adjust the resonant frequency point that antenna uses, thereby satisfy the needs under the different situations, need not to produce again the antenna of different resonant frequency points, save cost.
[summary of the invention]
Therefore, the invention provides a kind of antenna structure, to realize to change the purpose of the resonant frequency point of antenna according to different needs.
For achieving the above object, the invention provides a kind of antenna structure, it comprises:
An oscillator;
A short circuit arm, the one end is connected with above-mentioned oscillator, and this short circuit arm is provided with one first chute;
A grounded metal sheet, surface thereof is connected with the other end of above-mentioned short circuit arm, and this grounded metal sheet is provided with one second chute;
A transfer arm, it is located in above-mentioned first chute and second chute and slides in said two devices.
Especially, also be provided with a coaxial line feedback point on the above-mentioned short circuit arm.
Especially, also be provided with a coaxial line place on the above-mentioned grounded metal sheet.
Especially, the thickness of above-mentioned transfer arm is equal to or slightly less than the width of above-mentioned first chute and second chute.
In present embodiment, antenna structure of the present invention makes can change the effective length of oscillator as required in this antenna structure by having increased by first chute, second chute and transfer arm structure, and then reaches and change the variation that antenna uses resonant frequency point.
For purpose of the present invention, structural feature and function thereof are had further understanding, conjunction with figs. is described in detail as follows now:
[description of drawings]
Fig. 1 illustrates the schematic diagram of existing antenna structure.
Fig. 2 illustrates the schematic diagram of antenna structure of the present invention.
[embodiment]
With reference to shown in Figure 2, antenna structure of the present invention comprises:
An oscillator 1;
A short circuit arm 2, the one end is connected with above-mentioned oscillator 1, and this short circuit arm is provided with one first chute 21, and also is provided with a coaxial line feedback point 22 on this short circuit arm 2;
A grounded metal sheet 3, surface thereof is connected with the other end of above-mentioned short circuit arm 2, and this grounded metal sheet 3 is provided with
One second chute 31, and also be provided with a coaxial line place 32 on this grounded metal sheet 3;
A transfer arm 4, it is located in above-mentioned first chute 21 and second chute 31 and slides in said two devices, the thickness of this transfer arm 4 is equal to or slightly less than the width of above-mentioned first chute and 21 second chutes 31, so that transfer arm 4 can not become flexible in first chute and 21 second chutes 31.
In present embodiment, increased in the antenna structure of the present invention that a transfer arm 4 and this transfer arm can slide and the effective length that changes oscillator in first chute 21 and second chute 31, the resonant frequency point of antenna is changed, and then satisfy the antenna needs of different situations in use, need not to change other antennas, save a large amount of costs.
