Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.

Embodiment

Please refer to Fig. 1, better embodiment of the present invention provides a kind of radio communication device 100, and it can be mobile phone, personal digital assistant 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 these antenna 20 feed-in electric currents, and this earth point 14 provides ground connection for this antenna 20.

This antenna 20 is arranged on this carrier 10, and it can be configured to arbitrary shape, to receive and dispatch the wireless signal with any one frequency.In the present embodiment, this antenna 20 comprises a feeding portion 21, a grounding parts 22, a junction 23 and a Department of Radiation 24.This feeding portion 21 is a straight metal lamellar body, and the load point 12 on itself and carrier 10 is electrically connected, with feed-in electric current.This grounding parts 22 is that one " L " type gold housing belongs to lamellar body, and its one end is connected with feeding portion 21, and the earth point 14 on the other end and carrier 10 is electrically connected, so that flow into the electric current of this antenna 20, forms loop.

This connecting portion 23 is vertically connected between carrier 10 and Department of Radiation 24, thereby makes this Department of Radiation 24 be suspended at the top of carrier 10.This connecting portion 23 is connected with this feeding portion 21 and grounding parts 22, so that be passed to Department of Radiation 24 by the electric current of feeding portion 21 feed-ins through connecting portion 23, then is back to grounding parts 22 via connecting portion 23.In the present embodiment, this connecting portion 23 is a metal rectangular structure.

This Department of Radiation 24 is straight metal lamellar body, and its one end is connected in one end of the relatively described carrier 10 of connecting portion 23, and the other end extends towards the direction parallel with this grounding parts 22.

Refer to Fig. 2 and Fig. 3, this housing 30 is established this carrier 10 and antenna 20 for cover.This housing 30 comprises the first surface 31 that is oppositely arranged and second 32.On this housing 30, also have one and run through first surface 31 and second 's 32 mounting groove 34.When this housing 30 covers at antenna 20 top, the Department of Radiation 24 of this antenna 20 is roughly fitted with the first surface 31 of housing 30.

This regulating part 40 is made by electric conducting material, and as metal, it is mounted slidably on housing 30.Particularly, this regulating part 40 comprises extension 41 and the pushing part 42 being wholely set.This extension 41 is a straight metalwork.When regulating part 40 is arranged on housing 30, between this extension 41 and this first surface 31, form an interval (not shown), the Department of Radiation 24 of this antenna 20 of big or small tolerable at this interval is in the inner accommodating.So, extension 41 can contact with Department of Radiation 24, and partially overlaps, and a part of usining as this antenna 20, with the common transmitting/receiving wireless signal of Department of Radiation 24.In the present embodiment, when regulating part 40 is arranged on housing 30, this extension 41 be arranged in parallel up and down with Department of Radiation 24.This pushing part 42 is arranged at one end of this extension 41, and is slidably mounted in the mounting groove 34 of this housing 30.When External Force Acting is on this pushing part 42, this pushing part 42 can be in the interior slip of mounting groove 34, thereby drives this extension 41 motions, to change the position of these extension 41 relative Departments of Radiation 24.In the present embodiment, the initial position of these regulating part 40 relative housings 30 makes the wireless signal that these antenna 20 headend frequencies are 2400MHZ ~ 2500MHZ.For example, this initial position is the approximate mid-section position that this pushing part 42 is positioned at this mounting groove 34.

During assembling, first antenna 20 is fixedly arranged on carrier 10, and feeding portion 21 and the load point 12 on carrier 10 are electrically connected, the earth point 14 on grounding parts and carrier 10 is electrically connected.Then regulating part 40 is installed on housing 30, make pushing part 42 through the mounting groove 34 of described housing 30 and slide to be arranged in described mounting groove 34, extension 41 keeps certain intervals with the first surface 31 of described housing 30, to accommodate the Department of Radiation 24 of described antenna 20.Now, the Department of Radiation 24 of antenna 20 is connected in the extension 41 of described regulating part 40.

Below in conjunction with Fig. 2 and Fig. 4, further illustrate the operation principle of this radio communication device 100: when the installation environment change of antenna 20, for example this antenna 20 is placed under a certain specific communication environment or while being installed on other radio communication devices, will there is certain deviation in the resonance frequency of this antenna 20, for example, be partial to low frequency or deflection high frequency.Wherein, when the resonance frequency of this antenna 20 is partial to low frequency, now can promote this pushing part 42, extension 41 be slided, to change the position of these extension 41 relative Departments of Radiation 24 towards the direction near this connecting portion 23.Along with extension 41 is slided near the direction of connecting portion 23, the current path of this antenna 20 shortens thereupon, and its resonance frequency suitably increases, to meet the requirement of the wireless signal of transmitting-receiving characteristic frequency.Particularly, when extension 41 is positioned at initial position, the initial current path of antenna 20 is the length sum that feeding portion 21, connecting portion 23, Department of Radiation 24 and extension 41 exceed the part of Department of Radiation 24; When regulating part 40 slides into a side of close connecting portion 23 along mounting groove 34, the part that this extension 41 exceeds Department of Radiation 24 shortens, and therefore regulates the length of the current path of regulating part 40 aft antennas 20 to be less than the current path length while not regulating regulating part 40.

In like manner, when the resonance frequency deflection high frequency of antenna 20, promote this pushing part 42, extension 41 is slided towards the direction away from connecting portion 23, and then it is elongated to make extension 41 exceed the extension of antenna 20 Departments of Radiation 24.Because current path is elongated, now the resonance frequency of antenna 20 will suitably reduce, to reach the suitable object improving of resonance frequency that makes antenna 20.

Be appreciated that, the initial position of these regulating part 40 relative mounting grooves is not limited to the medium position that pushing part 42 is positioned at mounting groove 34, also can be the arbitrary position on mounting groove 34, only need to guarantee can make antenna 20 reach the wireless signal of transmitting-receiving characteristic frequency after adjusting regulating part 40.

Radio communication device 100 of the present invention is by arranging the regulating part 40 that metal material is made at housing 30, the relative housing 30 of regulating part 40 is slided, to change the position of regulating part 40 extension 41 relative antenna 20 Departments of Radiation 24, thereby change current path length, reaches the object of adjusting antenna 20 resonance frequencys.The resonance frequency of fine-tuning its inside antenna 20 of this radio communication device 100, makes the installation site of antenna 20 not be limited to specific installation region or specific radio communication device, has strengthened versatility and the adaptability of antenna 20.In addition,, by the resonance frequency of regulating part 40 fine setting antennas 20 is set, without adjusting frequency by increasing the mode of circuit unit, saved cost and guaranteed the good radiance of antenna.
