Embodiment
The present invention is described in further detail below by specific embodiment and with reference to attached drawing.
As shown in Figure 1, the present invention provides a kind of antenna of mobile terminal, which is used to receive and launch electromagnetic wave,
To realize the information exchange between mobile terminal and base station.
Specifically, the antenna includes becket 1 and circuit board 2.Wherein, becket 1 is loop configuration, it is arranged to edge
The outer edge extension of mobile terminal, also, becket 1 is arranged at least one radiator of antenna.
Circuit board 2 includes floor layer 22 and distributing point, and becket 1 is connected with distributing point and floor layer 22, on circuit board 2
Avoid holes 21 are offered, the thickness direction of avoid holes 21 along circuit board 2 runs through floor layer, and avoid holes 21 can be used for housing audio
Component etc., to improve the compactedness of structure.But simultaneously as the limitation of mobile terminal inner space, avoid holes 21 are usually located at
In the primary radiation area of antenna, this can influence the electromagnetic circuit of antenna, can especially be produced in high band (2300MHz~2690MHz)
Interference signal, causes antenna performance to decline.
For this reason, the present invention proposes, increase by a conductive sheet 3, the part of the conductive sheet 3 as antenna, makes it at least cover
A part of avoid holes 21, also, set the both ends of conductive sheet 3 to be connected respectively with floor layer 22.
After setting in a manner described, since the conductive sheet 3 for being connected across 21 both sides of avoid holes is connected with floor layer 22 respectively, because
This, opening up the floor layer 22 that avoid holes 21 are cut out can be compensated by conductive sheet 3, it is understood that be that conductive sheet 3 fills
When partially flaggy 22 cut out, when antenna is launched and receives electromagnetic wave, which can play floor layer 22
Effect, so as to improve the electromagnetic circuit of antenna, to eliminate the interference signal in working frequency range, thus lift antenna performance.
In the embodiment shown in fig. 1, conductive sheet 3 is welded and fixed with floor layer 22, and welding manner can ensure conductive sheet 3
With being reliably connected for floor layer 22, and then ensure reliable in electrical contact between the two.
In addition, the present invention is not construed as limiting the concrete shape of conductive sheet 3, in the embodiment shown in fig. 1, conductive sheet 3 with
22 coupling part of floor layer is slab construction, and middle to be swelled to the side away from floor layer 22, slab construction is easy to and floor layer
22 are bonded and weld, and ridge structure ensures that acoustic component can be housed in avoid holes 21 to step down to acoustic component.
On the other hand, when setting conductive sheet 3, the size of conductive sheet 3 in the Y direction can be increased as far as possible, so can be more
Mend size of the avoid holes 21 in this direction so that the performance of the antenna is optimized.
Please continue to refer to Fig. 1, the first gap 11 and the second gap 12 are offered on becket 1, becket 1 is via the first seam
11 and second gap 12 of gap is divided into three parts, including Part I 13 and Part II 14, Part I 13
Between the first gap 11 and the second gap 12, also, Part I 13 is arranged to the first radiator of antenna, the first radiation
Body is connected with distributing point and floor layer 22, and the first radiator can be connected by feeding shell foot with distributing point, similarly, the first spoke
Beam can also be connected by presenting ground shell foot with floor layer.
It is equal that Part II 14 includes the first earth point D1 and the second earth point D2, the first earth point D1 and the second earth point D2
It is connected with floor layer 22, also, part of the Part II 14 between the first earth point D1 and the second earth point D2 is set
Into the second radiator, the second radiator is not directly connected to distributing point, but with other radiator couple feeds.
Description more than, becket 1 are divided into some, and two parts therein are respectively arranged to antenna
Two radiators, each radiator can be used for receiving and launching the electromagnetic wave of different operating frequency range, so that the work of antenna
Frequency range is widened, and further lifts antenna performance.
According to one embodiment, the working frequency range of the first radiator could be provided as 824MHz~960MHz, the second radiation
The working frequency range of body could be provided as 1710MHz~2171MHz, it follows that the antenna at least covers low frequency band and intermediate frequency
Frequency range.
Further, as shown in Figures 2 and 3, which further includes metallic support 4, and metallic support 4 is arranged to the of antenna
Three radiators.Specifically, metallic support 4 is supported by circuit board 2, to be fixed in mobile terminal, metallic support 4 is via feed
Shell foot 5 is connected with the feed of Part I 13, and via feedback ground shell foot 6 and 13 grounding connection of Part I.
Wherein, metallic support 4 can use flexible PCB, can also use and be process by laser direct structuring technique
Stent.
According to one embodiment, the working frequency range of the 3rd radiator is 2300MHz~2690MHz, and the 3rd radiator is set
Put and allow antenna to cover high-frequency band, also, by the way that conductive sheet 3 to be connected across to the both sides of avoid holes 21, and and floor layer
22 connect this scheme so that the interference signal in high-frequency band is eliminated, its signal transmission quality is improved.
In order to improve antenna performance, circuit board 2 is provided with clearance zone, and clearance zone can ensure that radiator receives and transmitting
Electromagnetic wave can be transmitted smoothly, the metallic support 4 for being supported in circuit board 2, and clearance zone can be that the radiation of metallic support 4 carries
For empty regions, at this point it is possible to set the orthographic projection of metallic support 4 on the circuit board 2 at least to partly overlap with clearance zone.
More preferably, the orthographic projection of metallic support 4 on the circuit board 2 can also be set all overlapping with clearance zone, thus, can
Further to expand empty regions, so as to improve the ability that the 3rd radiator receives and launches electromagnetic wave, antenna performance is improved.
It is known that the second radiator is not direct is connected with distributing point in foregoing, but by the way of couple feed, the present invention
In, it is contemplated that the second radiator compared with the distance between metallic support 4 the distance between first radiator and metallic support 4 compared with
It is small, therefore, the second radiator and 4 couple feed of metallic support are set.Mobile terminal can be reduced by the way of couple feed
Interior connection circuit, simplifies internal structure.
Certainly, in some other embodiment, according to the difference of relative position between radiator, the second radiator can be with
With the first radiator couple feed, this is not limited by the present invention.
In addition, other positions of circuit board 2 can also be provided with clearance zone, such as close to the one of the second radiator
Side, it is possible thereby to improve the ability that the second radiator receives and launches electromagnetic wave, improves antenna performance.
Present invention also offers a kind of mobile terminal, which includes antenna, and antenna is in any of the above-described embodiment
Antenna.
Mobile terminal can make mobile phone, ipda and POS machine etc., and this is not limited by the present invention.
The foregoing is only a preferred embodiment of the present invention, is not intended to limit the invention, for the skill of this area
For art personnel, the invention may be variously modified and varied.Within the spirit and principles of the invention, that is made any repaiies
Change, equivalent substitution, improvement etc., should all be included in the protection scope of the present invention.
