Abstract
The utility model discloses a mobile phone antenna structure, comprising an antenna part and a metal ground terminal. The antenna part comprises an antenna provided with a feed-in terminal and an earth terminal. The metal ground terminal is electrically connected with the earth terminal of the antenna. Wherein, the metal ground terminal comprises a flake base whose edge bends and extends upwards to form an extension part, thereby expanding the area of the metal ground terminal, effectively dispersing the electric field distribution in the ground terminal and reaching the aim of decreasing the antenna SAR measured value.
Description
Affiliated technical field
The utility model relates to a kind of antenna structure of mobile phole, relates in particular to a kind of antenna structure of mobile phole of the SAR of reduction value.
Background technology
Flourish along with current mobile communication technology, the design of mobile phone day by day requires compact and attractive in appearance, therefore, the antenna structure of mobile phone is developed by the helical antenna that exposed to mobile phone in the past and a kind of concealed antenna that is hidden in mobile phone inside, but the thing followed is the increase of SAR (SpecificAbsorption Rate) value of antenna integral body, thereby human body is damaged, run in the opposite direction with the trend that requires the low SAR value of mobile phone now day by day.
In the conventional art, can utilize the change of mobile phone thickness and outward appearance to reduce the SAR value of antenna, but under the frivolous day by day trend of mobile phone, antenna and mobile phone are all very thin, simple dependence changes cell phone appearance and is difficult to satisfy requirement to the antenna SAR value.
As shown in Figure 2, a kind of antenna structure of mobile phole 1 ' of prior art comprises that an antenna part 10 ' that is positioned at mobile phone (not shown) front end reaches the metal ground end 20 ' that is connected and is positioned at antenna part 10 ' below with antenna part 10 '.Described metal ground end 20 ' matching with mobile phone shell (not shown) shape and rectangular laminar.Antenna part 10 ' comprises a PCB (Printed Circuit Board) plate 11 ' and is printed in the antenna 12 ' of this pcb board 11 ' upper surface.Antenna 12 ' is provided with feed side 13 ' and earth terminal 14 ', and earth terminal 14 ' is connected conducting with metal ground end 20 ' downwards by pcb board 11 '.
In the above-mentioned existing antenna structure of mobile phole 1 ', be subjected to the restriction of phone housing because of the area of described rectangular laminar metal ground end 20 ', make that the Electric Field Distribution in this metal ground end 20 ' is comparatively concentrated, thereby cause the SAR value of prior art antenna structure of mobile phole 1 ' excessive.
The utility model content
The purpose of this utility model is to provide a kind of a kind of antenna structure of mobile phole that provides, and can effectively reduce the SAR value of antenna.
For achieving the above object, a kind of antenna structure of mobile phole provided by the utility model comprises antenna part and metal ground end.Antenna part comprises antenna, and antenna is provided with feed side and earth terminal.Metal ground end electrically connects with the earth terminal of described antenna.Wherein, described metal ground end comprises that one is laminar base portion, base portion matching with mobile phone shell shape, and this base portion periphery upwards bending extend to form extension.
As the improvement of the utility model antenna structure of mobile phole, described antenna part comprises that further one is printed with the pcb board of described antenna, and the earth terminal of described antenna electrically connects by pcb board and described metal ground end.
As the improvement of the utility model antenna structure of mobile phole, described antenna part is arranged at the mobile phone front end, and metal ground end is positioned at the antenna part bottom side, and the earth terminal of described antenna electrically connects with described metal ground end downwards by pcb board.
As the improvement of the utility model antenna structure of mobile phole, described base portion matching with mobile phone shell shape and rectangular laminar.
As the improvement of the utility model antenna structure of mobile phole, described base portion in a side and back end edge respectively upwards bending extend to form and be approximately perpendicular to base portion and as first kink of extension.
As the improvement of the utility model antenna structure of mobile phole, described first kink bends inwards in upper edge place and extends to form second kink as extension along being roughly parallel to the base portion direction.
As mentioned above, the utility model antenna structure of mobile phole is by metal ground end periphery upwards the bending structural design of extending and the area of expanded metal ground end, the effective Electric Field Distribution in the dispersed metal ground end, the purpose of realization reduction antenna SAR value.

Embodiment
By describing technology contents of the present utility model, structural feature in detail, being realized purpose and effect, below exemplify embodiment and cooperate the graphic detailed explanation of giving.
See also Fig. 1, the utility model antenna structure of mobile phole 1 comprises an antenna part 10 and the metal ground end 20 that electrically connects with antenna part 10.In the present embodiment, antenna part 10 is arranged at mobile phone (not shown) front end, and metal ground end 20 stretches out backward from antenna part 10 bottoms.But antenna part 10 and metal ground end 20 are not limited to only be located at above-mentioned position.
From the above, the utility model antenna structure of mobile phole 1 is by the bending design of above-mentioned base portion 21 peripheries according to the phone housing shape, make that 20 area is held on expanded metal ground under the situation that does not change cell phone appearance and size, effectively the Electric Field Distribution in 20 is held on dispersed metal ground, realizes reducing the purpose of antenna SAR value.
In sum, the utility model antenna structure of mobile phole is by the explanation of the foregoing description and correlative type, concrete, full and accurate exposure correlation technique, those skilled in the art can be implemented according to this.And the embodiment of the above just is used for illustrating the utility model, rather than is used for limiting of the present utility model, and interest field of the present utility model should be defined by claim of the present utility model.Still all should belong to interest field of the present utility model as for the change of described component number or the replacement of equivalence element etc. herein.
