Specific embodiment
Referring to Fig. 1, the better embodiment of the present invention provides a kind of wireless 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, shell 30 and regulating part 40.
The carrier 10 can be the circuit board of wireless communication device 100, and a load point 12 and a grounding point 14 are arranged 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 set on carrier 10, 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, an interconnecting piece 25 and an irradiation unit
26.The feeding portion 22 is a straight metal sheet, is electrically connected with the load point 12 on carrier 10, to obtain electric current.It should
Grounding parts 24 are the metal sheet of " L " type, are electrically connected with the grounding point 14 on carrier 10, so as to the ground connection of antenna 20.
The interconnecting piece 25 is vertically connected between carrier 10 and irradiation unit 26, so that irradiation unit 26 is suspended on carrier 10
Side.The interconnecting piece 25 is electrically connected with feeding portion 22 and grounding parts 24 simultaneously, so that the electric current of feeding portion 22 is passed through interconnecting piece 25
It is handed to irradiation unit 26, and is back to grounding parts 24 through interconnecting piece 25.In the present embodiment, which is made of metal
Rectangular parallelepiped structure.
The irradiation unit 26 is straight metal sheet comprising the first linkage section 267, the second linkage section 268 and third connect
Connect section 269.One end of first linkage section 267 is connected to the one end of interconnecting piece 25 with respect to feeding portion 22, and court and grounding parts 24
Parallel direction extends to cross the grounding parts 24.Second linkage section 268 is vertically connected at the first linkage section 267 and third connects
It connects between section 269.The third linkage section 269 it is parallel with the first linkage section 267 and interval setting, and towards close to interconnecting piece 25 side
To extension.In the present embodiment, the length of first linkage section 267 is longer than the length of third linkage section 269.
For the shell 30 for being provide with carrier 10 and antenna 20, which includes outside the inner surface 32 and one being oppositely arranged
Surface 34 also opens up a mounting hole 36 through inner surface 32 and outer surface 34 on the shell 30.When the shell 30 is located at day
When 20 top of line, the irradiation unit 26 of the antenna 20 is substantially bonded with the inner surface 32 of shell 30.
The regulating part 40 is made of insulating material, and dielectric coefficient is higher than air.The regulating part 40 is slidably arranged on
On shell 30.The regulating part 40 includes the occlusion part 42 being wholely set and pushing part 44.The occlusion part 42 is set to shell 30
Inner surface 32, and an interval is formed between the inner surface 32, the size at the interval can make irradiation unit 26 of antenna 20
Divide or all accommodates in the inner.In this way, the occlusion part 42 can partly or entirely block the irradiation unit 26.The pushing part 44 is set to
On occlusion part 42, and it can be slid through mounting hole 36.When external force is when on the pushing part 44,40 phase of regulating part can be pushed
Shell 30 is slided, to change the area that irradiation unit 26 is blocked.
In the present embodiment, which may make occlusion part 42 substantially to block radiation with respect to the initial position of shell 30
1/3 area in portion 26.At this point, the antenna 20 can headend frequency be 1575MHz wireless signal (GPS signal).
Below with reference to Fig. 2 and Fig. 3, the working principle of the wireless communication device 100 is further illustrated: around antenna 20
When working environment changes, such as antenna 20 is set to another space of the wireless communication device 100, or the antenna 20 is applied
When similar wireless communication device, the resonant frequency of the antenna 20 will generate certain offset, such as be biased to high frequency.At this point, pushing away
Move the pushing part 44, make regulating part 40 towards close to interconnecting piece 25 direction slide, and then increase irradiation unit 26 be blocked portion 42 screening
The area of gear.Since the dielectric coefficient of the regulating part 40 is higher than air, it is easy to have an impact the characteristic of antenna 20, with radiation
The area that portion 42 blocks that is blocked of portion 26 increases, so that the resonant frequency of antenna 20 suitably reduces, to meet transmitting-receiving, certain is wireless
The design requirement of signal.
Similarly, when the resonant frequency of antenna 20 is biased to low frequency, the pushing part 44 is pushed, makes regulating part 40 towards far from connection
The direction in portion 25 is slided, and then is reduced irradiation unit 26 and be blocked the area that portion 42 blocks, to reach the resonant frequency for making antenna 20
Appropriate increased purpose.
It is appreciated that the regulating part 40, which is not limited to occlusion part 42 with respect to the initial position of shell 30, substantially blocks irradiation unit
26 1/3 area can not also block irradiation unit 26 for occlusion part 42 completely.
Wireless communication device 100 of the invention is being arranged regulating part 40 made of insulating materials in shell 30, so that adjusting
It saves part 40 to slide with respect to shell 30, is conditioned the area that part 40 blocks to change antenna 20, and then adjust the resonance frequency of antenna 20
Rate improves antenna 20 because of different installation environment bring frequency deviations.The resonance frequency of the fine-tuning antenna 20 of wireless communication device 100
Rate enhances the versatility of antenna 20.
