By using the antenna provided by the invention, the appearance of the shell is not needed to be damaged, so that the appearance of the shell is kept attractive, and a high-frequency signal in the shell is directly sent to the scatterer, so that the aim of successfully radiating the signal is achieved.
Description
Technical field
The present invention relates to a kind of antenna, relate in particular to a kind of antenna being arranged on shell.
Background technology
For highlighting the honorable and graceful of mobile device, metal fuselage design has become fashion, utilizes part metals fuselage to become gradually industry common recognition as a part for antenna.At present, each relevant manufacturer adopts the mode of metal conduction to be used as high-frequency signal transmission path conventionally, do entity with antenna and contact, but this type of mode by the design that destroys mobile device shell with attractive in appearance, or increase the difficulty on assembling.The mode of metal conduction mainly contains electrically conducting hole (Plating Through Hole/Plating Via), shell fragment or probe contact (Spring/Pogo-Pin Contact), male and female die face is climbed line and screw connected mode.
Electrically conducting hole is done shell and " is holed to move and " change afterwards plating processing and make hole wall conducting, and then allow antenna be combined with signal source, shortcoming: the making flow process complexity in electrically conducting hole, yield is on the low side, cost increases, and shell wrecks, and has affected the attractive in appearance of shell.
Shell fragment or the probe way of contact, common die face need be carried out to " holes moves " to expose the metal antenna part of shell, by shell fragment or probe contact, antenna is combined with signal source again, shortcoming: the common die face of shell suffers destruction to a certain degree, by the stress structure that makes shell built on the sand, even cause casing deformation.
It is by MID (Molded Interconnection Device that male and female die face is climbed line mode, interconnection moulding) processing procedure designs by common die face antenna geometries (ANT Pattern) to master mold face direction, although can avoid destroying shell, but, in the antenna geometries of shell edge, long-time use can produce wearing and tearing, and then destroys, affects antenna performance, can cause the air-tightness problem of mobile device simultaneously.
It is that inside antenna geometry is passed through to screw connected with outer casing that screw links the way of contact, combines closely each other, and the two is antenna monomer important structure, shortcoming: assembling flow path step becomes complicated, and factory's yield declines, and packaging technology technology need significantly promote.
So, be necessary to design new antenna to solve the problems of the technologies described above.
Summary of the invention
The object of the present invention is to provide a kind of antenna that guarantees casing appearance that has.
For realizing aforementioned object, the present invention adopts following technical scheme: a kind of antenna, be arranged on shell, it comprises and is arranged in the scattering object on outer surface of outer cover and is arranged in the antenna body on inner surface of outer cover, described scattering object is in order to carry out radiation or guiding radiation, described scattering object comprises parasitic element, scattering assembly, guider and reflector, described antenna body aligns in the wall thickness direction of shell mutually with scattering object, between antenna body and scattering object, can carry out electrically conducting in the mode of capacitive couplings.
Antenna of the present invention is owing to can carrying out electrically conducting in the mode of capacitive couplings between antenna body and scattering object, need not destroy the outward appearance of shell, guarantee the attractive in appearance of shell, directly the high-frequency signal in shell has been delivered to scattering object, reached smoothly signal radiation object.
Accompanying drawing explanation
Fig. 1 antenna part of the present invention is arranged in the schematic diagram on outer surface of outer cover.
Fig. 2 antenna another part of the present invention is arranged in the schematic diagram on inner surface of outer cover.
Fig. 3 application has the schematic cross-section of the shell of antenna of the present invention.
Embodiment
Refer to shown in Fig. 1 to Fig. 3, antenna of the present invention comprises and is arranged in the scattering object 21 on plastic shell 1 outer surface 11 and is arranged in the antenna body 22 on shell 1 inner surface 12, antenna body 1 is a part for shell 1 surface metal plating layer 13, scattering object 21 is in order to carry out radiation or guiding radiation, it at least comprises parasitic element, scattering assembly, guider, reflector, antenna body 22 is connected with the signal source in mobile device, and align and make to form capacitive couplings between the two with scattering object 21 in shell 1 wall thickness direction, need not destroy the outward appearance of shell 1, guarantee the attractive in appearance of shell 1, directly the high-frequency signal in shell 1 is delivered to scattering object 21, reach smoothly signal radiation object.The suitable reduction of shell 1 wall thickness can allow as much as possible mutually close each other, to reach preferably coupling effect.
Method for designing and the step of antenna of the present invention are as follows:
The 1st step, finds suitable mobile device, and its shell 1 outer surface 11 contains metal shell or metal outer frame, utilizes its part metals coating 13 to be used as the scattering object 21 of antenna, and scattering object 21 comprises parasitic element, scattering assembly, guider, reflector.
The 2nd step, the antenna body 22 of design exciting radiation mechanism, antenna body 22 is arranged in shell 1 inner surface 11, and selects suitable position, feed side in mobile device inside, and antenna body 22 aligns with scattering object 21, forms capacitive couplings between the two.
Finally, last according to different antenna environment, geometry and the conductor spacing of fine setting antenna body 22, to obtain the antenna of a characteristic frequency and impedance matching, make electromagnetism wave energy be smoothly through scattering object 21 and radiate, and reaches the optimization of antenna performance.
The main purpose of antenna of the present invention is utilizing shell 1 inner surface area, and the geometry of designing antenna main body 22 is directed to electromagnetic wave by capacitive coupling feed-in mode on the scattering object 21 of shell 1 simultaneously and outwards radiate by antenna body 22.
Antenna of the present invention is without shell 1 being destroyed to (boring or holes), do not need Antenna Design in shell 1 edge, avoid easy wearing and tearing, do not need to increase in the situation of assembling flow path step, meet under the metallized demand of shell 1, utilize conductive characteristic, be combined with antenna system dexterously, take into account aerial radiation function and product design requirement.
Antenna of the present invention can be used for the types such as utmost point sub antenna, unipole antenna, inverse-F antenna, PIFA antenna.
Although be example object, the preferred embodiment of the present invention is disclosed, but those of ordinary skill in the art will recognize, in the situation that not departing from by the disclosed scope and spirit of the present invention of appending claims, various improvement, increase and replacement are possible.
