Embodiment
Referring to Fig. 1, the better embodiment of the present invention provides a kind of radio communication device 100, it can be mobile phone
Or personal digital assistant (Personal Digital Assistant, PDA) etc..
In the present embodiment, which includes carrier 10, antenna 20, housing 30 and regulating part 40.
The carrier 10 can be the circuit board of radio communication device 100, set a load point 12 and an earth point 14 thereon, should
Load point 12 is used to be 20 feed-in electric current of antenna, which is used to provide ground connection for antenna 20.
The antenna 20 is arranged on carrier 10, it can be configured to arbitrary shape, to receive and dispatch the nothing with any one frequency
Line signal, such as transmitting/receiving wireless fidelity（Wireless fidelity, WIFI）Signal, or transmitting-receiving global positioning system（Global
Position System, GPS）Signal.
In the present embodiment, which includes a feeding portion 22, a grounding parts 24, a supporting part 25, one first radiation
26 and 1 second irradiation unit 27 of portion.The feeding portion 22 is a straight metal sheet, it is electrical with the load point 12 on carrier 10
Connection, to obtain electric current.The grounding parts 24 are the metal sheet of " L " type, its one end and the electricity of earth point 14 on carrier 10
Property connection, so that antenna 20 is grounded, the other end is connected with feeding portion 22.
The supporting part 25 is vertically connected between 10 and first irradiation unit 26 of carrier, so that the first irradiation unit 26 is suspended at load
The top of body 10.The supporting part 25 is electrically connected with feeding portion 22 and grounding parts 24 at the same time, is passed through so as to the electric current of 22 feed-in of feeding portion
Supporting part 25 is transferred to the first irradiation unit 26, and is back to grounding parts 24 through supporting part 25.In the present embodiment, the supporting part 25
One is rectangular parallelepiped structure made of metal.
First irradiation unit, 26 and second irradiation unit 27 is straight metal sheet, the two is coplanar and is arranged at intervals, together
Shi Jun is attached on housing 30.Wherein, one end of first irradiation unit 26 is connected to the one end of supporting part 25 with respect to feeding portion 22,
And extend towards the direction parallel with grounding parts 24 to cross the grounding parts 24.One end of second irradiation unit 27 and the first irradiation unit
One end of 26 opposite supporting parts 25 is substantially aligned, and the centre position of the other end and the first irradiation unit 26 is substantially aligned.
The housing 30 is used to be provide with carrier 10 and antenna 20, which is included outside the inner surface 32 and one that is oppositely arranged
Surface 34, also open up on the housing 30 one through inner surface 32 and outer surface 34 mounting hole 36.When the housing 30 is located at day
During 20 top of line, the first irradiation unit 26 and the second irradiation unit 27 of the antenna 20 are attached at the inner surface 32 of housing 30.
The regulating part 40 is made of an electrically conducting material, such as metal.The regulating part 40 is slidably arranged on housing 30.The tune
Section part 40 includes connecting portion 42 and the pushing part 44 being wholely set.The connecting portion 42 is arranged at the inner surface 32 of housing 30, and with
An interval is formed between the inner surface 32, the size at the interval causes the first irradiation unit 26 and the second irradiation unit of antenna 20 just
27 pass through.Meanwhile the length of the connecting portion 42 is slightly longer than the spacing between the first irradiation unit 26 and the second irradiation unit 27 so that even
Socket part 42 can be across the side for the inner surface 32 for being arranged at 27 opposite housing 30 of the first irradiation unit 26 and the second irradiation unit, with connection
Between the first irradiation unit 26 and the second irradiation unit 27.The pushing part 44 is arranged on connecting portion 42, and can be slid through installation
Hole 36.When external force is acted on the pushing part 44, the regulating part 40 can be promoted to be slided with respect to housing 30, to change connecting portion 42
With respect to the position of the first irradiation unit 26 and the second irradiation unit 27.
In the present embodiment, which may be such that connecting portion 42 is connected to the first spoke with respect to the initial position of housing 30
Penetrate 26 and second irradiation unit 27 of portion one end opposite with supporting part 25.At this time, the antenna 20 can headend frequency be 1575MHz
Wireless signal（Gps signal）.
With reference to Fig. 2 and Fig. 3, the operation principle of the radio communication device 100 is further illustrated：Around antenna 20
When working environment changes, such as antenna 20 is arranged to another space of the radio communication device 100, or the antenna 20 is applied
When similar radio communication device, the resonant frequency of the antenna 20 will produce certain offset, such as be inclined to low frequency.At this time, push away
The pushing part 44 is moved, regulating part 40 is slided towards close to the direction of supporting part 25, so that 42 and first irradiation unit of connecting portion
26 and second the link position of irradiation unit 27 change.As connecting portion 42 is close to the slip of the direction of supporting part 25, the antenna
20 current path is reduced therewith, its resonant frequency suitably increases, to meet to receive and dispatch the design requirement of certain wireless signal.Example
Such as, in initial position, the initial current path of antenna 20 is feeding portion 22, supporting part 25, the first irradiation unit 26, connecting portion 42
And second irradiation unit 27 the sum of length, when regulating part 40 is another towards the second irradiation unit 27 is slid into close to the direction of supporting part 25
During end, the first current path of the antenna 20 is the sum of length of feeding portion 22,25 and first irradiation unit 26 of supporting part, and second is electric
Flow path is feeding portion 22, supporting part 25, the first irradiation unit 26 are connected to part between supporting part 25 and connecting portion 42, connection
42 and second irradiation unit 27 of portion.Obviously, the first current path of the antenna 20 and the length of the second current path are respectively less than initial
The length of current path.
Thereafter, if the resonant frequency of antenna 20 is inclined to high frequency, the pushing part 44 is promoted, makes regulating part 40 towards away from support
The direction in portion 25 is slided, to increase current path, and then the purpose for making the resonant frequency of antenna 20 suitably reduce.
It is appreciated that the regulating part 40 is not limited to connecting portion 42 with respect to the initial position of housing 30 is connected to the first radiation
26 and second irradiation unit 27 of portion one end opposite with supporting part 25, or connecting portion 42 are substantially connected to the second irradiation unit 27 1
Half position.
The radio communication device 100 of the present invention in housing 30 by setting regulating part 40 made of conductive material so that adjusts
Section part 40 is slided with respect to housing 30, to change the current path of antenna 20, and then is adjusted the resonant frequency of antenna 20, is improved antenna
20 frequency deviations brought by different installation environments.The resonant frequency of the fine-tuning antenna 20 of the radio communication device 100, enhances day
The versatility of line 20.
