Utility model content
For this reason, the day of resonance is adjusted by varying antenna body length the purpose of this utility model is to provide a kind of
Line, to ensure that low-frequency range is more efficient.
The purpose of this utility model is achieved through the following technical solutions.
A kind of adjustable antenna of resonance, including the antenna body being arranged on mainboard clearance zone, described antenna body one end
The mainboard is connected to by a distributing point, a feedback place respectively；The other end of the antenna body be provided with first switch and
Second switch.
Preferably, the first connecting line and the second connecting line of mainboard clearance zone are provided perpendicular on the antenna body,
The antenna body is connected by first connecting line with the distributing point, passes through second connecting line and the feedback place
Connection.
Preferably, the 3rd connecting line and the 4th connecting line of mainboard clearance zone are provided perpendicular on the antenna body,
Connected between 3rd connecting line and the 4th connecting line by the first switch.
Preferably, the 5th connecting line and the 6th connecting line of mainboard clearance zone are provided perpendicular on the antenna body,
Connected between 5th connecting line and the 6th connecting line by the second switch.
The adjustable antenna of resonance provided by the utility model, using the switch being arranged on antenna body, passes through switch
Shut-off, realizes the change of antenna body length, so as to fulfill the adjusting of antenna resonance, and then makes the adjustability of antenna stronger, low
Frequency range is more efficient.Compared with prior art, the utility model is simple in structure, and antenna resonance, which is adjusted, to be more prone to, and it is linear
Can be more preferable.

Embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, is further elaborated the utility model.It should be appreciated that specific embodiment described herein is only explaining
The utility model, is not used to limit the utility model.
Refering to Figure 1, Fig. 1 is the front schematic view of the new antenna of this practicality.The utility model provides a kind of change
Antenna body length adjusts the antenna of resonance, it is correspondingly arranged on the mainboard 1 of handheld device (such as mobile phone).
Wherein mainboard 1 includes line areas and clearance zone, and line areas is the corresponding electronic circuit area for connecting other electronic devices
Domain, clearance zone is logicalnot circuit region, and the antenna body 101 of antenna is then arranged in the clearance zone of mainboard 1.
A distributing point 201 and a feedback place 202 are correspondingly arranged on line areas, and one end of antenna body 101 is then
The line areas of mainboard 1 is connected to by distributing point 201 and feedback place 202 respectively.
First switch 1001 and second switch 1002 are correspondingly arranged on the other end of antenna body 101.Opened by first
Close the shut-off of 1001 and second switch 1002, it is possible to achieve the adjusting of 101 entire length of antenna body.
It should be noted that what is selected in the present embodiment is length adjustment of two switch realizations to antenna body 101,
In other embodiment, the switch (such as 3 and more than) of varying number can be selected, required for can equally reaching the present embodiment
The purpose reached, should not be construed as the limitation to the utility model.
As shown in Fig. 2, Fig. 2 is the partial schematic diagram of the utility model antenna.From figure 2 it can be seen that antenna body 101
Parallel to whole mainboard 1, its one end is provided perpendicular to the first connecting line and the second connecting line of 1 clearance zone of mainboard, the other end
It is provided perpendicular to the 3rd connecting line, the 4th connecting line, the 5th connecting line and the 6th connecting line of 1 clearance zone of mainboard.
Antenna body 101 is connected by the first connecting line with distributing point 201, is connected by the second connecting line and feedback place 202
Connect.And first switch 1001 is provided between the 3rd connecting line and the 4th connecting line, between the 5th connecting line and the 6th connecting line
It is provided with second switch 1002.
By disconnecting first switch 1001 or second switch 1002, the length of antenna body 101 can all be reduced, and it is right
Answer the antenna body 101 of different length, the frequency of its respective antenna resonance also corresponds to different.
As shown in figure 3, Fig. 3 is the return loss schematic diagram of the utility model antenna.Antenna passes through feed in the present embodiment
Feed, be grounded by presenting at place 202, the both ends of switch are connected with antenna respectively at point 201.Pass through opening for two switches of control
Close to adjust the frequency of resonance
When first switch 1001 is opened and when second switch 1002 is whether opened or closed, return loss is in S1
State 1.
When first switch 1001 is closed and when second switch 1002 is opened, return loss is the state 1_1 in S1.
When first switch 1001 and second switch 1002 close at the same time, return loss is the state 1_2 in S1.
In conclusion first, the essence of the utility model is to adjust resonant frequency by varying the length of antenna body,
For tradition is by way of the chip such as antenna tuning switch or variable capacitance, it adjusts the mode of resonant frequency for it
Simpler convenience.Secondly for the utility model, due to changing antenna body by switch-mode regulation folding, its correspondence
Length, can be by increasing the length of antenna body therefore when low frequency part is adjusted, can be more than traditional scheme performance
It is good.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
