Abstract
The invention provides an antenna structure integrated in a metal shell. The antenna structure comprises a metal shell of an electronic device, a circuit substrate arranged in the metal shell, and an antenna radiation circuit, wherein the antenna radiation circuit with a certain shape is formed by bending of a long bar-shaped metal and is arranged at the circuit substrate. The metal shell includes a plurality of side surfaces; and a slit is arranged at one of the multiple side surfaces. One end of the antenna radiation circuit is contacted with the side surface provided with the slit and approaches one end of the slit; and the side surface that is not contacted with the antenna radiation circuit and approaches the other end of the slit is grounded. With the antenna structure, because the slit is arranged at one side of the metal shell, and one end of the side is contacted with the antenna radiation circuit and the other end is grounded, the slit of the shell is used as one part of the antenna radiation circuit, so that a problem that the existing antenna has to avoid to use a shell made of the metal material can be solved; and thus the antenna has the good characteristics and the product miniaturization requirement is also met.
Description
Technical field
The present invention relates to a kind of antenna structure that is integrated in metal shell.
Background technology
Due to the development of wireless communication technique, electronic product requires more and more to pay attention to for the quality of reception of signal, for example global positioning system (GPS) navigation feature or mobile communication ability etc.Meanwhile, electronic industry requires, under the characteristic such as light, thin, short, little, to add that the chip characteristics of highly integration is to reach the object of miniaturization for electronic product.
At present, electronic product on the market can be with metal shell coating circuit plate and antenna structure, and this metal shell has advantages of that intensity is high, not fragile, have metal-like, but uses above-mentioned metal shell, due to metal shell shielding, can cause the efficiency of antenna structure not good.Therefore, in order to solve the incompatible problem of characteristic of metal shell and antenna, conventionally must use complicated, expensive assemble method, to avoid both interference problems in characteristic, therefore cause the cost of product to rise.On the other hand, along with the microminiaturization of electronic product, make in order to the insufficient space of allotment, to cause the assembling of above-mentioned metal shell and antenna, the interference problem of arrangement is serious.
Summary of the invention
In view of this, be necessary to provide a kind of antenna structure that is integrated in metal shell, so that antenna has preferably characteristic, and then make antenna meet the electronic product of microminiaturization.
The invention provides a kind of antenna structure that is integrated in metal shell, the metal shell, one that comprises an electronic installation is arranged at circuit substrate and in this metal shell forms by strip metal bending have definite shape and be arranged at the aerial radiation circuit on this circuit substrate, this metal shell comprises a plurality of sides, one of them of the plurality of side offered a slit, one end of this aerial radiation circuit and the contacts side surfaces that this slit is set, and near one end of this slit, contact with this aerial radiation circuit and this side ground connection of close this slit other end.
Use foregoing invention, be integrated in the antenna structure of metal shell, in the side of metal shell, offer a slit, one end of this side contacts with aerial radiation circuit, other end ground connection, thereby make the slit of this shell as a part for aerial radiation circuit, to solve traditional antenna, must avoid the problem of the shell of metal material, and then meet the requirement of product microminiaturization when making antenna there is better characteristic.

Following embodiment further illustrates the present invention in connection with above-mentioned accompanying drawing.
Embodiment
Below in conjunction with accompanying drawing, the present invention is described in further detail.
Please refer to Fig. 1 and 2, it is the partial schematic diagram of the antenna structure that is integrated in metal shell in first embodiment of the invention.This antenna structure that is integrated in metal shell has the circuit substrate 11 and that the shell 10, of an electronic installation is arranged in this shell 10 and is located at the aerial radiation circuit 12 on this circuit substrate 11.
Wherein, this shell 10 comprises a plurality of sides 100, and the slit 101 of this side 100 of a perforation is offered in one of them side 100.This shell 10 is the made metal shell of a metal material, and this side 100 of offering slit 101 forms complete metal surface through material processed.In the present embodiment, this slit 101 is L-shaped, and the longer sides in L shaped offers along the edge on the long limit of this side 100, compared with minor face towards offering perpendicular to the long side direction of this side 100.Wherein, this slit 101 can be opened on these shell 10 any one sides 100.
This aerial radiation circuit 12 is arranged on circuit substrate 11, and forms the effigurate conductive path of tool by the metal bending of a strip.This aerial radiation circuit 12 is in electrical contact with the side 100 that this slit 101 is set, and this arranges side 100 ground connection of slit 101, thereby the slit 101 that makes this shell 10 can be used as a part for this aerial radiation circuit 12, it can solve the problem that traditional antenna must be avoided the shell 10 of metal material.Correspondingly, change the efficiency that the width of slit 101 and the parameter of aerial radiation circuit can increase antenna.In the present embodiment, an end of this aerial radiation circuit 12 and this side 100 that slit 101 is set are in electrical contact.In another embodiment, the position and this side 100 that slit 101 is set that in this aerial radiation circuit 12, are positioned in the middle of circuit are in electrical contact.
Refer to Fig. 3-5, for the present invention is integrated in the structural representation of other execution modes of the antenna structure of metal shell, the shape of this aerial radiation circuit 12 and distribution can be arbitrary shape and distribution as in Figure 3-5, thereby by changing shape and the distribution of this aerial radiation circuit 12, correspondingly change the frequency range, efficiency of antenna etc.
The present invention is integrated in the antenna structure of metal shell, in the side of metal shell, offer a slit, one end of this side contacts with aerial radiation circuit, other end ground connection, thereby make the slit of this shell as a part for aerial radiation circuit, to solve traditional antenna, must avoid the problem of the shell of metal material, and then meet the requirement of product microminiaturization when making antenna there is better characteristic.
Be understandable that, for the person of ordinary skill of the art, can make other various corresponding changes and distortion by technical conceive according to the present invention, and all these change and distortion all should belong to the protection range of the claims in the present invention.
