Specific embodiment
Below by specific embodiment combination attached drawing, invention is further described in detail.
Existing mobile terminal structure is as shown in Figure 1, include nonmetallic frame 1, display panel 2 and Anneta module, antennaModule is placed in the empty regions between nonmetallic frame 1 and display panel 2, and the inner surface of nonmetallic frame 1 is connected with buckle4, and the size of Anneta module is 80mm*9.5mm*2mm, if the mobile terminal is fabricated to high screen accounting, narrow frame,It needs to compress empty regions, and limited space is easy the performance of limitation Anneta module, it is therefore, existing mobile wholeThe structure of the Anneta module at end designs, it is not easy to realize high screen accounting, the purpose of narrow frame.
Embodiment one:
For the problem that existing Anneta module size is big, it is not easy to realize mobile terminal Gao Ping, narrow frame, this example provides one kindNarrow frame mobile terminal, structure chart is as shown in Fig. 2, include that nonmetallic frame 1, display panel 2 and extension item 3, extension item 3 are embeddingEnter inside nonmetallic frame 1, and a part of extension item 3 or entirety are extended to first antenna module, nonmetallic frame 1Inner surface is connected with buckle 4, is empty regions between nonmetallic frame 1 and display panel 2, since this example is by extending item 3Realize the function of antenna, and extending item 3 is inside the nonmetallic frame 1 of insertion, to save the space of empty regions, also favorablyIn the realization of antenna performance, it can further realize and extend on the top of display panel 2 to empty regions, to realize mobile terminalHeight screen accounting, narrow frame.
Further, first antenna module is equipped with feed detail 5, and the free end of feed detail 5 extends in empty regions, leads toSimple feed detail 5 is crossed directly to connect with extension item 3.
When a part for extending item 3 is extended to first antenna module, the realization shape of extension 3 rest part of item is not limitedFormula, then LDS, FPC or PCB construction can be extended to by extending 3 another part of item, and extension item 3 is metal strip.
In other embodiments, extension item 3 can stick in nonmetallic 1 surface of frame, and e.g., extension item 3 sticks in non-goldBelong to outer surface or the inner surface of frame 1.
Embodiment two:
Based on embodiment one, the antenna assumption diagram of the mobile terminal of this example is as shown in figure 3, this example increases in empty regionsSecond Anneta module, it is preferred that the size of the second Anneta module is 80mm*7mm*2mm, and the size of existing Anneta module is bigSmall is 80mm*9.5mm*2mm, and compared with existing Anneta module, the Y-direction size of second Anneta module of this example is from 9.5mmIt is reduced to 7mm, to achieve the purpose that save empty regions space, by the way that a part for extending item 3 to be extended to first dayWire module, and by coupleeing the performance that the second Anneta module reaches existing Anneta module for first antenna module, then, thenThe top of display panel 2 is extended to the empty regions of saving, high the screen accounting, narrow frame purpose of mobile terminal may be implemented.
Shown in the return loss plot of the Anneta module of this example such as Fig. 4 (a), the return loss plot of existing Anneta module such as Fig. 4(b) shown in, from the point of view of the two comparison, the two is on close level, that is, even if the Y-direction size of the second Anneta module is reduced to from 9.5mm7mm still can satisfy the bandwidth requirement of LTE/3G/GPS (700~960MHz, 1710~2700MHz).
Efficiency comparative's figure of the efficiency of the Anneta module of this example and existing Anneta module as shown in figure 5, from the point of view of the two comparison,The two is on close level, that is, even if the Y-direction size of the second Anneta module is reduced to 7mm from 9.5mm and still can satisfy LTE/The bandwidth requirement of 3G/GPS (700~960MHz, 1710~2700MHz).
Embodiment three:
Based on embodiment two, the mobile terminal of this example further includes connection detail 6, and first antenna module passes through connection detail 6It is connect with the second Anneta module, the number of connection detail 6 is at least one, in second Anneta module and embodiment two of this exampleSecond antenna module structure, size are identical.
Extension item 3 is embedded in the structure chart inside nonmetallic frame 1 as shown in fig. 6, extension item 3 sticks in nonmetallic frameThe structure chart of 1 outer surface is as shown in Figure 7.
The application extends item 3 by being embedded in nonmetallic frame 1, or pastes extension item 3 on nonmetallic 1 surface of frame,And Anneta module is extended by extending item 3, to reduce the Y-direction size of Anneta module accordingly, to reduce antennaModule is taken up space in empty regions, in turn, the top of display panel can be extended to the empty regions of saving, to realizeHigh the screen accounting, the purpose of narrow frame of mobile terminal.
Use above specific case is illustrated the present invention, is merely used to help understand the present invention, not to limitThe system present invention.For those skilled in the art, according to the thought of the present invention, can also make several simpleIt deduces, deform or replaces.
