Description
Technical field
The utility model relates to a kind of antenna, particularly relates to a kind of antenna with metal frame.
Background technology
At present, metal frame on the market/the application of frame antenna on smart terminal product emerges in an endless stream, also prove that the interest of consumer to metallic terminations product is dense, product is on outward appearance, performance and structural strength etc. require, it is all well and good selection, but find be substantially all with metal frame crack gap form occur, that is metal frame/frame to be disconnected to realize the Net long wave radiation of antenna, but pinpoint the problems after disconnecting: General Requirements symmetry disconnects in appearance, in structure, the requirement of intensity reduces, and implements and causes the complexity of technique also to increase.
Please refer to shown in Fig. 1, existing structure multifrequency antenna, it utilizes the breaking part of metal frame 10 to form two gaps 11,12, as certain part of antenna resonance, can produce one, the demand of two or above frequency band resonance, all the other resonance portion need to realize by FPC or by the mode of other mode build paths on support, final whole antenna comes together to realize the function of multifrequency antenna, has following shortcoming:
1. design can not once confirm, the position in above-mentioned gap 11,12 can not be determined at the beginning of design, and need to combine design below, slowly break-in could determine final dimensional requirement;
2. product appearance needs to make a concession, likely affect attractive in appearance and symmetrical;
3., because metal frame 10 is disconnected, reduce structural strength;
4. processes injection moulding, the mode such as to be insert molded realize, and cost is high.
Although the mode that above-mentioned disconnection metal frame 10 forms gap 11,12 is commonly used by mainstream models such as apple Iphone mobile phones, Cost Problems is still difficult to spread to low and middle-end type.
Utility model content
The purpose of this utility model there are provided a kind of have improve mobile product antenna attractive in appearance.
For realizing aforementioned object, the utility model adopts following technical scheme: a kind of antenna, it comprises the framework in order to mobile product, the metal frame of shell or metal edge frame, be positioned at plastic cement block and the coaxial line of metal frame, described plastic cement block forms radiation metal circuit, described coaxial line and radiation metal circuit weld together, described metal frame is partial to high frequency radiation, described radiation metal circuit is partial to low frequency radiation, described metal frame is uninterrupted metal frame, described metal frame comprises front end edge, back end edge and connect the relative dual-side of front end edge and back end edge, described radiation metal circuit and front end edge contact.
As further improvement of the utility model, described plastic cement block is protruding upward in metal frame, and radiation metal circuit is at least partially higher than metal frame.
As further improvement of the utility model, described antenna also comprises electric capacity coaxial line and radiation metal circuit are cascaded.
As further improvement of the utility model, described side is higher than front and back ends limit, and side has protruding upward in the arcuate projections on front and back ends limit.
As further improvement of the utility model, described radiation metal circuit adopts the mode of FPC to realize.
The metal frame of the utility model antenna is uninterrupted metal frame, described metal frame comprises front end edge, back end edge and connects the relative dual-side of front end edge and back end edge, described radiation metal circuit and front end edge contact, metal frame structural strength is high, add the attractive in appearance of product simultaneously, antenna structure is simple, is easily integrated in mobile product, is applicable to the appearance requirement of mobile product.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of antenna in prior art.
Fig. 2 is the schematic perspective view of the utility model antenna.
Fig. 3 is the floor map of the utility model antenna.
Embodiment
Refer to shown in Fig. 2 to Fig. 3, the utility model antenna 20 is in order to be located in mobile product, and it comprises a uninterrupted metal frame 21, plastic cement block 22, coaxial line 23 and an electric capacity 24.
Metal frame 21 is formed in one, and can be used as the framework of mobile product, shell, metal edge frame etc.Metal frame 21 comprises front end edge 211, back end edge 212 and connects the relative dual-side 213 of front end edge 211 and back end edge 212, dual-side 213 higher than front and back ends limit 211,212, dual-side 213 has protruding upward in the arcuate projections 214 on front and back ends limit 211,212 respectively, reduces the metal interference of metal frame 21 pairs of radiation metal circuits 221.
Plastic cement block 22 is positioned at metal frame 21, and be affixed by front end edge 211 inner surface, plastic cement block 22 is formed with radiation metal circuit 221, radiation metal circuit 221 and front end edge 211 contact, radiation metal circuit 221 is partial to the high frequency radiation of antenna 20, and metal frame 21 is partial to the low frequency radiation of antenna 20.
Plastic cement block 22 is protruding upward in metal frame 21, makes the radiation metal circuit 221 of a part higher than metal frame 21, reduces blocking of metal frame 21 pairs of radiation metal circuits 221, improve the radiation efficiency of radiation metal circuit 221, improve the usefulness of antenna 10.In other embodiments, radiation metal circuit 221 adopts FPC(Flexible Printed Circuit board, flexible flat) mode realize.
Coaxial line 23 has conductor 231 and ground connection braid 232, and conductor 231 is together with electric capacity 24, and electric capacity 24 welds with radiation metal circuit 221, together with being connected on by conductor 231, solves the problem that antenna 20 low frequency length is inadequate with radiation metal circuit 221.Ground connection braid 232 links together with metal frame 21 or mobile product motherboard.Certainly, conductor 231 also can directly and radiation metal circuit 221 weld together.
The utility model antenna 10 adopts uninterrupted metal frame 21, and metal frame 21 structural strength is high, adds the attractive in appearance of product simultaneously, and antenna 20 structure is simple, is easily integrated in mobile product, is applicable to the appearance requirement of mobile product.
Although be example object, disclose preferred implementation of the present utility model, but those of ordinary skill in the art will recognize, when not departing from scope and spirit of the present utility model disclosed in appending claims, various improvement, increase and replacement are possible.
