Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Refer to Fig. 1, the present invention's better embodiment provides a kind of radio communication device 100, and it can be mobile phone or personal digital assistant (Personal Digital Assistant, PDA) etc.
In the present embodiment, this radio communication device 100 comprises carrier 10, antenna 20, housing 30 and regulating part 40.
This carrier 10 can be the circuit board of radio communication device 100, and a load point 12 and an earth point 14 are set on it, and this load point 12 is used to antenna 20 feed-in electric currents, and this earth point 14 is used to antenna 20 that ground connection is provided.
This antenna 20 is arranged on carrier 10, and it can be configured to arbitrary shape, to receive and dispatch the wireless signal with any one frequency, transmitting/receiving wireless fidelity (wireless fidelity for example, WIFI) signal, or transmitting-receiving global positioning system (Global Position System, GPS) signal.
In the present embodiment, this antenna 20 comprises a feeding portion 22, a grounding parts 24, a junction 25 and a Department of Radiation 26.This feeding portion 22 is a straight metal lamellar body, and the load point 12 on itself and carrier 10 is electrically connected, to obtain electric current.This grounding parts 24 be one " L " type metal lamellar body, the earth point 14 on itself and carrier 10 is electrically connected, so that antenna 20 ground connection.
This connecting portion 25 is vertically connected between carrier 10 and Department of Radiation 26, so that Department of Radiation 26 is suspended at carrier 10 tops.This connecting portion 25 is electrically connected with feeding portion 22 and grounding parts 24 simultaneously, so that the electric current of feeding portion 22 is passed to Department of Radiation 26 through connecting portion 25, and is back to grounding parts 24 through connecting portion 25.In the present embodiment, this connecting portion 25 1 is metal rectangular structure.
This Department of Radiation 26 is straight metal lamellar body, and it comprises the first linkage section 267, the second linkage section 268 and the 3rd linkage section 269.One end of this first linkage section 267 is connected in one end of connecting portion 25 relative feeding portions 22, and extends to cross this grounding parts 24 towards the direction parallel with grounding parts 24.This second linkage section 268 is vertically connected between the first linkage section 267 and the 3rd linkage section 269.The 3rd linkage section 269 and interval parallel with the first linkage section 267 arranges, and extends towards the direction near connecting portion 25.In the present embodiment, the length of this first linkage section 267 is longer than the length of the 3rd linkage section 269.
This housing 30 is established carrier 10 and antenna 20 for cover, and this housing 30 comprises an inner surface 32 and the outer surface 34 being oppositely arranged, and also offers an installing hole 36 that runs through inner surface 32 and outer surface 34 on this housing 30.When this housing 30 is located at antenna 20 top, the Department of Radiation 26 of this antenna 20 is roughly fitted with the inner surface 32 of housing 30.
This regulating part 40 is made by insulating material, and its dielectric coefficient is higher than air.This regulating part 40 is slidably arranged on housing 30.This regulating part 40 comprises occlusion part 42 and the pushing part 44 being wholely set.This occlusion part 42 is arranged at the inner surface 32 of housing 30, and and this inner surface 32 between form an interval, the size at this interval can be so that the Department of Radiation of antenna 20 26 be partly or entirely in the inner accommodating.So, this occlusion part 42 can partly or entirely block this Department of Radiation 26.This pushing part 44 is arranged on occlusion part 42, and slidably through installing hole 36.When External Force Acting is on this pushing part 44, can promotes the relative housing 30 of this regulating part 40 and slide, the area being blocked to change Department of Radiation 26.
In the present embodiment, the initial position of these regulating part 40 relative housings 30 can make occlusion part 42 roughly block 1/3 area of Department of Radiation 26.Now, this antenna 20 can headend frequency the wireless signal (gps signal) that is 1575MHz.
Below in conjunction with Fig. 2 and Fig. 3, further illustrate the operation principle of this radio communication device 100: when antenna 20 operational environment around changes, for example antenna 20 is arranged to another space of this radio communication device 100, while maybe this antenna 20 being applied to similar radio communication device, the resonance frequency of this antenna 20 will produce certain skew, as deflection high frequency.Now, promote this pushing part 44, make regulating part 40 towards sliding near the direction of connecting portion 25, and then increase Department of Radiation 26 area that portion 42 blocks that is blocked.Because the dielectric coefficient of this regulating part 40 is higher than air, easily the characteristic of antenna 20 is exerted an influence, along with Department of Radiation 26 area that portion 42 blocks that is blocked increases, the resonance frequency of antenna 20 is suitably reduced, to meet the designing requirement of certain wireless signal of transmitting-receiving.
In like manner, when the resonance frequency of antenna 20 is partial to low frequency, promote this pushing part 44, regulating part 40 is slided towards the direction away from connecting portion 25, and then reduce Department of Radiation 26 area that portion 42 blocks that is blocked, the object that makes the resonance frequency of antenna 20 suitably increase to reach.
The initial position that is appreciated that these regulating part 40 relative housings 30 is not limited to 1/3 area that occlusion part 42 roughly blocks Department of Radiation 26, also can be occlusion part 42 and does not block Department of Radiation 26 completely.
