Description
Technical field
The present invention relates to a kind of antenna structures being integrated in metal shell.
Background technology
Due to the development of wireless communication technique, electronic product requires increasingly to pay attention to for the quality of reception of signal, such as
Global positioning system（GPS）Navigation feature or mobile communication ability etc..Meanwhile electronic industry is for electronic product requirement
Under the characteristics such as gently, thin, short, small, in addition the chip characteristics of high integration are to achieve the purpose that miniaturization.
Currently, electronic product on the market can have with metal shell coating circuit plate and antenna structure, the metal shell
Intensity is high, be hardly damaged, has the advantages that metal-like, but uses above-mentioned metal shell, due to the original of metal shell shielding
Cause can cause the efficiency of antenna structure bad.Therefore, in order to solve the problems, such as that the characteristic of metal shell and antenna is incompatible, lead to
Chang Bixu to avoid the interference problem of the two characteristically, therefore leads to the cost of product using complicated, high-cost assemble method
Rise.On the other hand, with the microminiaturization of electronic product so that the insufficient space that can be used to allocate leads to above-mentioned metal shell
The interference problem of assembling, arrangement with antenna is serious.
Invention content
In view of this, it is necessary to provide a kind of antenna structure being integrated in metal shell, so that antenna has preferably spy
Property, and then antenna is made to meet the electronic product of microminiaturization.
The present invention provides a kind of antenna structure being integrated in metal shell, including the metal shell of an electronic device, one sets
It the circuit board that is placed in the metal shell and one there is definite shape and is set to the electricity by what strip metal bending was formed
Aerial radiation circuit on base board, the metal shell include multiple sides, and one of multiple side opens up a slit,
One end of the aerial radiation circuit be arranged the slit side contact, and close to the slit one end, not with the aerial radiation
The side ground of wiring circuit contact and the close slit other end.
Using foregoing invention, it is integrated in the antenna structure of metal shell, opens up a slit in the side of metal shell, the side
The one end in face and aerial radiation electrical contact, other end ground connection, to make the slit of the shell one as aerial radiation circuit
Part, to solve the problems, such as that traditional antenna must avoid the shell of metal material, and then make antenna have preferable characteristic while
Meet product microminiaturization requirement.

Following specific implementation mode will be further illustrated the present invention in conjunction with above-mentioned attached drawing.
Specific implementation mode
Below in conjunction with attached drawing, the present invention is described in further detail.
It is the office of the antenna structure for being integrated in metal shell in first embodiment of the invention please refer to Fig. 1 and 2
Portion's schematic diagram.There is the antenna structure for being integrated in metal shell the shell 10, one of an electronic device to be set in the shell 10
Circuit board 11 and one be set to the circuit board 11 on aerial radiation circuit 12.
Wherein, which includes multiple sides 100, and one of side 100 opens up the slit of the perforation side 100
101.The shell 10 is the metal shell made by a metal material, which passes through material processing shape
At complete metal surface.In the present embodiment, the slit 101 is L-shaped, and the longer sides in L-shaped are along the length of the side 100
The edge on side, shorter edge are opened up towards the long side direction perpendicular to the side 100.Wherein, which it is outer can be opened in this
On any one side 100 of shell 10.
The aerial radiation circuit 12 is arranged in circuit board 11, and is formed with certain by the metal bending of a strip
The conductive path of shape.The aerial radiation circuit 12 and the side 100 that the slit 101 is arranged are in electrical contact, and the setting is narrow
The side 100 of seam 101 is grounded, can to make the slit 101 of the shell 10 can be used as a part for the aerial radiation circuit 12
Solve the problems, such as that traditional antenna must avoid the shell 10 of metal material.Correspondingly, change the width and antenna spoke of slit 101
The parameter on ray road can increase the efficiency of antenna.In the present embodiment, an end of the aerial radiation circuit 12 is set with this
The side 100 for setting slit 101 is in electrical contact.In another embodiment, it is located among circuit in the aerial radiation circuit 12
