Abstract
The utility model relates to an antenna structure of a metal casing radiotelephone. The antenna structure is arranged in the radiotelephone provided with a plastic bottom casing and a metal front cover, and a printed circuit board provided with a ground is arranged between the bottom casing and the front cover. A grounding pin, the ground of the printed circuit board and the metal front cover are electrically connected to change the flow direction of electric current of the antenna structure and to change the electromagnetic field distribution of the radiotelephone, so that the radiation efficiency of the antenna structure can be increased.
Description
Technical field
The utility model designs about a kind of mobile phone structure, refers to a kind of antenna structure of metal shell mobile phone especially.
Background technology
In some mobile phones design, can be with metal shell coating circuit plate and antenna structure, to reach some special function, advantage such as for example shell is not fragile.But in this kind metal shell mobile phone, because the cause that metal shell covers, regular meeting makes that the efficient of antenna structure is not good.
Before TaiWan, China patent of invention notification number is counted I254554 " metallic mobile phone shell structure " patent, in the case, disclose a kind of metallic mobile phone shell structure, contained a loam cake and a lower cover.The loam cake both sides have a chute respectively, and the lower cover both sides have the slide block with respect to chute respectively, and when sliding in chute when slide block embedding chute, loam cake engages with lower cover, and holds a mobile phone main body between loam cake and lower cover.Lower cover further contains an antenna cover groove and a battery cover groove.When an antenna cover and a battery cover are equipped in antenna cover groove and battery cover groove, further fixed cover and lower cover respectively.Obviously the antenna structure in this case is not connected with the metallic mobile phone housing.
Again, in United States Patent (USP) 7,327,324, be about one pole groove shape antenna (Monopole slot antenna), Fig. 5 A in this preceding case has disclosed a metal shell mobile phone and has had a groove shape antenna (metalradiotelephone casings having a slot antenna).But similarly, this antenna structure also originally is connected with the metallic mobile phone housing.
In traditional metal shell mobile phone, the flat metal radiant body of its antenna structure polyphyly, by nonmetal coating, plastic cement for example, simultaneously, extended feed-in pin and grounding leg in the antenna structure are connected on the feed-in contact and ground contact of circuit board, then ground contact then with circuit board on ground (Ground) connect conductivity and be connected.But such antenna structure design is a major reason that causes efficient not good, remains to be improved.
Summary of the invention
The utility model purpose is, a kind of antenna structure of metal shell mobile phone is provided, because the shortcoming of prior art is improved, provides a kind of antenna structure design of metal shell mobile phone, to improve antenna efficiency.
The antenna structure of a kind of metal shell mobile phone of the utility model, this antenna structure are arranged in the mobile phone, and this mobile phone has a plastic cement drain pan and a metal material protecgulum, and are provided with a printed circuit board (PCB) with a ground between this drain pan and protecgulum; It is characterized in that: the protecgulum conduction of the grounding leg of this antenna structure, the ground of this printed circuit board (PCB) and this metal material connects.
Wherein, a metallic screw is locked on this printed circuit board (PCB) outside the protecgulum of this metal material.
The utility model beneficial effect: by said structure, changed the current direction of this antenna structure, thereby the electromagnetic field that has changed this mobile phone distributes, and has improved the radiation efficiency of this antenna structure.
Below, will structure of the present utility model and effect be described in detail according to the embodiment shown in the drawing.
Description of drawings
Fig. 1 represents the exploded view according to a kind of embodiment of the present utility model,
Another angular views of antenna structure in Figure 1A representative graph 1,
Fig. 2 represents the part cutaway view according to a kind of embodiment of the present utility model.
Embodiment
See also Fig. 1, antenna structure for a kind of metal shell mobile phone of the utility model, this antenna structure 1 is set in the mobile phone 2, and this mobile phone 2 has the drain pan 21 of a plastic cement and the protecgulum 22 of a metal material, and this drain pan 21 and 22 of protecgulums are provided with a printed circuit board (PCB) 23 with a ground.
Be set on the substrate 12 and constitute and antenna structure 1 is a flat metal radiant body 11.Referring to Figure 1A, metal radiant body 11 has a feed-in pin 111 and a grounding leg 112 to extend to the bottom surface of substrate 12.After combination, feed-in pin 111 and grounding leg 112 respectively can with feed-in contact 231 and ground contact 232 being connected on the printed circuit board (PCB) 23 with conductivity.And the protecgulum 22 of the ground of the grounding leg 112 of antenna structure 1, printed circuit board (PCB) 23 and this metal material is for example locked outside the protecgulum 22 of this metal material on this printed circuit board (PCB) 23 with the screw 3 of a metal with the connection of conductivity, can be referring to shown in Figure 2.By changing the current direction of antenna structure 1, the electromagnetic field that changes this mobile phone 2 distributes, to improve the radiation efficiency of antenna structure 1.
Following form is the test result that is not connected metal shell at antenna connection metal shell of the present utility model and antenna:
Through experiment test, the antenna structure of metal shell mobile phone provided by the utility model as can be known, be not connected to metal shell compared to known metal shell antenna for mobile phone grounding leg, the efficient of its antenna (Efficiency) can comparatively increase, and makes the reception of mobile phone significantly improve.
Claims (2)
1. the antenna structure of a metal shell mobile phone, this antenna structure is arranged in the mobile phone, and this mobile phone has a plastic cement drain pan and a metal material protecgulum, and is provided with a printed circuit board (PCB) with a ground between this drain pan and protecgulum; It is characterized in that: the protecgulum conduction of the grounding leg of this antenna structure, the ground of this printed circuit board (PCB) and this metal material connects.
2. according to the antenna structure of the described metal shell mobile phone of claim 1, it is characterized in that a metallic screw is locked on this printed circuit board (PCB) outside the protecgulum of this metal material.
