The present invention that the following detailed description will be further explained with reference to the above drawings.

Specific embodiment

Please refer to Fig. 1, better embodiment of the invention provides a kind of wireless communication device 100, can for mobile phone, Personal digital assistant 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 the 20 feed-in electric current of antenna, which is that the antenna 20 provides ground connection.

The antenna 20 is set on the carrier 10, can be configured to arbitrary shape, has any one frequency to receive and dispatch Wireless signal.In the present embodiment, which includes a feeding portion 21, a grounding parts 22, an interconnecting piece 23 and an irradiation unit 24.The feeding portion 21 is a straight metal sheet, is electrically connected with the load point 12 on carrier 10, with feed-in electric current.It should Grounding parts 22 are " L " type golden shell body category sheet body, and one end is connect with feeding portion 21, the grounding point 14 on the other end and carrier 10 It is electrically connected, so as to flow into the electric current forming circuit of the antenna 20.

The interconnecting piece 23 is vertically connected between carrier 10 and irradiation unit 24, so that the irradiation unit 24 is suspended at carrier 10 top.The interconnecting piece 23 is connect with the feeding portion 21 and grounding parts 22, so that by the electric current of 21 feed-in of feeding portion through even Socket part 23 is transferred to irradiation unit 24, then is back to grounding parts 22 via interconnecting piece 23.In the present embodiment, which is one Rectangular parallelepiped structure made of metal.

The irradiation unit 24 is straight metal sheet, and one end is connected to one end of the relatively described carrier 10 of interconnecting piece 23, The other end extends towards the direction parallel with the grounding parts 22.

Please refer to figs. 2 and 3, and the shell 30 is for being provide with the carrier 10 and antenna 20.The shell 30 includes being oppositely arranged The first face 31 and the second face 32.A mounting groove 34 through the first face 31 and the second face 32 is also provided on the shell 30.When this When shell 30 covers at 20 top of antenna, the irradiation unit 24 of the antenna 20 is substantially bonded with the first face 31 of shell 30.

The regulating part 40 is made of an electrically conducting material, and such as metal, is slidably disposed on shell 30.Specifically, the tune Section part 40 includes the extension 41 being wholely set and pushing part 42.The extension 41 is a straight metalwork.When regulating part 40 An interval (not shown) is formed when being set on shell 30, between the extension 41 and first face 31, the size at the interval can The irradiation unit 24 of the antenna 20 is allowed to accommodate in the inner.In this way, extension 41 can be contacted with irradiation unit 24, and partially overlap, with As a part of the antenna 20, with the common transmitting/receiving wireless signal of irradiation unit 24.In the present embodiment, when regulating part 40 is set to When on shell 30, which is arranged in parallel with about 24 irradiation unit.The pushing part 42 is set to one end of the extension 41, And it is slidably mounted in the mounting groove 34 of the shell 30.When external force is when on the pushing part 42, which can It is slided in mounting groove 34, to drive the extension 41 to move, to change the position in the 41 relative radiation portion 24 of extension.? In the present embodiment, the regulating part 40 with respect to shell 30 initial position make the 20 headend frequency of antenna be 2400MHZ ~ The wireless signal of 2500MHZ.For example, the initial position is the approximate mid-section position that the pushing part 42 is located at the mounting groove 34.

When assembly, first antenna 20 is fixedly arranged on carrier 10, and keeps the load point 12 on feeding portion 21 and carrier 10 electrical Grounding point 14 on connection, grounding parts and carrier 10 is electrically connected.Then regulating part 40 is installed on shell 30, makes pushing part 42 pass through the mounting groove 34 of the shell 30 and are slideably positioned in the mounting groove 34, and the of extension 41 and the shell 30 31 certain intervals are kept on one side, to accommodate the irradiation unit 24 of the antenna 20.At this point, the irradiation unit 24 of antenna 20 be connected to it is described The extension 41 of regulating part 40.

Below with reference to Fig. 2 and Fig. 4, the working principle of the wireless communication device 100 is further illustrated: when the installation of antenna 20 Environment changes, such as when being placed under a certain specific communication environment by the antenna 20 or be installed on other wireless communication devices, should Certain deviation will occur for the resonant frequency of antenna 20, such as is biased to low frequency or is biased to high frequency.Wherein, when the resonance of the antenna 20 When frequency is biased to low frequency, the pushing part 42 can be pushed at this time, slide extension 41 towards the direction close to the interconnecting piece 23, to change Become the position in the 41 relative radiation portion 24 of extension.As extension 41 is slided close to the direction of interconnecting piece 23, the antenna 20 Current path shortens therewith, and resonant frequency suitably increases, to meet the requirement of the wireless signal of transmitting-receiving specific frequency.Specifically Ground, when extension 41 is located at initial position, the initial current path of antenna 20 is feeding portion 21, interconnecting piece 23, irradiation unit 24 And extension 41 exceeds the sum of the length of part of irradiation unit 24;When regulating part 40 slides into along mounting groove 34 close to interconnecting piece When 23 side, which shortens beyond the part of irradiation unit 24, therefore adjusts the electric current road of 40 aft antenna 20 of regulating part The length of diameter is less than current path length when not adjusting regulating part 40.

Similarly, when the resonant frequency of antenna 20 is biased to high frequency, the pushing part 42 is pushed, 41 company of being directed away from of extension is made The direction of socket part 23 is slided, so that extension of the extension 41 beyond 20 irradiation unit 24 of antenna is elongated.Due to electric current road Diameter is elongated, and the resonant frequency of antenna 20 will be reduced suitably at this time, to reach the mesh for properly increasing the resonant frequency of antenna 20 's.

It is appreciated that the regulating part 40, which is not limited to pushing part 42 with respect to the initial position of mounting groove, is located at mounting groove 34 Medium position can also be any position on mounting groove 34, need to only guarantee antenna 20 can be made to reach transmitting-receiving after adjusting regulating part 40 The wireless signal of specific frequency.

Wireless communication device 100 of the invention is being arranged regulating part 40 made of metal material in shell 30, so that adjusting It saves part 40 to slide with respect to shell 30, to change the position of 40 extension of regulating part, 41 relative antenna, 20 irradiation unit 24, to change Current path length achievees the purpose that adjust 20 resonant frequency of antenna.Its fine-tuning internal antenna 20 of the wireless communication device 100 Resonant frequency increase so that the installation site of antenna 20 is not only restricted to specific installation region or specific wireless communication device The strong versatility and adaptability of antenna 20.In addition, the resonant frequency of antenna 20 is finely tuned by setting regulating part 40, without passing through Increase the mode of circuit unit adjusting frequency, having saved cost and ensure that the good radiance of antenna.
