Abstract
Disclosed in the utility model is a coupling feed-in type mobile terminal antenna apparatus comprising a metal intermediate frame and a metal plate. An antenna support is arranged between the metal intermediate frame and the metal plate and an antenna connector is arranged on the metal plate. A first antenna branch and a second antenna branch are arranged at the antenna support; the first antenna branch is connected with a radio frequency feed-in signal of a main board by the antenna connector and is used as a feed-in branch; and the second antenna branch is connected with the metal intermediate frame and is coupled with the first antenna branch, so that an antenna resonant path is formed at the metal intermediate frame. With the antenna apparatus, the seamless design is realized. Reduction of the antenna performance can be avoided no matter whether the user holds the apparatus by hands or not; and problems that the structure strength of the seam and the seam is not beautiful can be solved.
Description
Technical field
The utility model relates to a kind of antenna assembly of mobile terminal, relates in particular to a kind of coupling feed-in type mobile terminal antenna device.
Background technology
On hand-held mobile terminal, adopt metal shell to replace plastic casing, not only can promote its metal-like, strengthen outward appearance expressive force, also can strengthen to a great extent structural strength.But metal-back is known from experience to Antenna Design and is brought very large difficulty, traditional PIFA, IFA, loop, the antenna forms such as Monopole are difficult to effectively realize thereon.By have gap on metal center, structure LOOP antenna is current general solution, yet gap not only affects outward appearance, affects the structural strength of complete machine simultaneously, and when people holds gap, can cause antenna performance sharply to decline.
Summary of the invention
The purpose of this utility model is to provide a kind of coupling feed-in type mobile terminal antenna device, this antenna assembly is by the mode of coupling feed-in metal center, make metal center become a part for antenna, on metal center, form antenna resonance route, realize a kind of seamless metal center antenna, to solve above-mentioned problems of the prior art.
The utility model solves technical problem by the following technical programs:
A kind of coupling feed-in type mobile terminal antenna device, comprise metal center and metallic plate, between described metal center and metallic plate, be provided with antenna holder, described metallic plate is provided with antenna connector, described antenna holder is provided with the first antenna branch and the second antenna branch, described the first antenna branch connects the radio frequency FD feed on mainboard by described antenna connector, as feed-in branch, described the second antenna branch is connected with metal center, and be coupled with the first antenna branch, on metal center, form antenna resonance path.
Preferably, described metal center and metallic plate are two separated structures.
Preferably, described metal center and metallic plate are integral structures.
Preferably, effective radiation frequency range of this antenna assembly is 700M-1000M and 1700M-2600M.
The coupling feed-in type mobile terminal antenna device that the utility model provides, be provided with two antenna branch, the first antenna branch is as feed-in branch, the energy of self-feed line is fed into antenna assembly in the future, due to the first antenna branch and the coupling of the second antenna branch, energy can transfer to the second antenna branch from the first antenna branch, again because the second antenna branch is connected with metal center, on metal center, form antenna resonance path, energy flows into metal center, to required direction, radiate, realized seamless antenna assembly, can not cause because of holding antenna performance to decline, simultaneously, the structural strength of mobile phone is improved, also strengthened aesthetic property.
Accompanying drawing explanation
Fig. 1 is the mobile phone metal shell construction of the utility model embodiment;
Fig. 2 is the coupling feed-in type antenna device for mobile phone of the utility model embodiment.
Embodiment
Preferred embodiment the utility model is described in further detail to contrast accompanying drawing combination below.
Embodiment
A kind of mobile phone metal shell construction that Figure 1 shows that the antenna assembly that uses the present embodiment, comprises metal center 10, surrounds mobile phone side, also comprise as antenna system the metallic plate 11 held, on described metallic plate 11, place LCD, battery, PCB mainboard etc.Between metal center 10 and metallic plate 11, form a headroom district 12, in order to place antenna holder.
Fig. 2 shows a kind of antenna assembly specific embodiment of the present utility model, described antenna holder comprises the first antenna branch 22 and the second antenna branch 23, wherein the first antenna branch 22 connects radio frequency FD feed by an antenna connector (not shown) being positioned on PCB mainboard 21, the second antenna branch 23 is connected to metal center 10, in the utility model, the first antenna branch 22 and the second antenna branch 23 couplings.When mobile phone need to transmit, need the energy of radiation to send into the first antenna branch 22 by feeder line, the first antenna branch 22 will need the energy (for example high-frequency current) of radiation to transfer to the second antenna branch 23, because the second antenna branch 23 is connected to metal center 10, on metal center 10, form antenna resonance path, energy can be radiated to required direction with electromagnetic form by antenna resonance path, completes transmitting.This antenna assembly is reversible, and when wireless device receives, electromagnetic wave is by this antenna resonance path, form with high-frequency current enters the second antenna branch 23, then transfers to the first antenna branch 22, passes through antenna connector, enter PCB mainboard, process, complete reception.
Need explanation, effective radiation frequency range of this antenna assembly can cover 700M-1000M and 1700M-2600M.
In antenna assembly Zhong， headroom of the present utility model district 12, not only can place antenna holder, can also place loud speaker, microphone, USB, earphone etc., be conducive to complete machine stacking.
Antenna assembly of the present utility model, adopt the mode of coupling feed-in metal center, overcome the problem that gap causes antenna performance to decline of holding existing in existing seamed center antenna scheme, and solved and affect structural strength problem and the inaesthetic problem of profile because of gap.
Above content is in conjunction with concrete preferred implementation further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of ordinary skill in the field; without departing from the concept of the premise utility; can also make some being equal to substitutes or obvious modification, and performance or purposes identical, all should be considered as belonging to protection range of the present utility model.
