Problems solved by technology

[0006] However, in current mobile terminals, interfaces such as USB tend to be centered. The former solution is easily affected by USB, resulting in poor antenna performance, and it is difficult to achieve both medium and high frequency performance; High, if the antenna environment is poor, such as insufficient clearance, the mid-high frequency performance will be relatively poor

Embodiment 1

[0059] see Figure 4 , the mobile terminal antenna 400 includes a first antenna body 410 and a second antenna body 420 . The first antenna body 410 includes: a base portion 411, a first branch portion 412, a second branch portion 413 and a bent portion 414; the first branch portion 412 and the second branch portion 413 are located on one side of the extension direction of the base portion 411 , the second branch portion 413 is located between the first branch portion 412 and the bent portion 414 , the first branch portion 412 is provided with an antenna site, and the second branch portion 413 is provided with an antenna feed point.

[0060] The bent portion 414 is located on the other side of the base portion 411 in the extension direction, and includes a connection portion 415 connected to the base portion 411 and an extension portion 416 connected to the connection portion 415 and extending toward the one side.

[0061] The second antenna body 420 is disposed parallel to th...

Embodiment 2

[0071] Figure 5 A schematic diagram showing the antenna structure of the mobile terminal according to the second embodiment of the present invention. The structure of the mobile terminal antenna 500 is similar to that of the mobile terminal antenna 400 . The main difference is that the second antenna main body 520 is not located on the second branch portion 513, but on the side thereof. In addition, the connecting portion 515 also includes a hollow gap, which can be used to avoid, for example, a speaker.

[0072] In Embodiment 2, the distance a between the second antenna main body 520 and the second branch part 513 on its left side (in the direction of extension) is 0.5 mm, and the distance a between the extension part 516 and the second branch part 513 is 5mm, the distance d between the second antenna body 520 and the extension 516 is 1.5mm, the length e of the second antenna body 520 is 20mm, the length f of the extension 516 is 17mm, the distance g between the extension ...

Embodiment 3

[0074] Figure 6 A schematic diagram showing the antenna structure of the mobile terminal according to the third embodiment of the present invention. The structure of the mobile terminal antenna 600 is similar to that of the mobile terminal antenna 400 . The main difference is that the second antenna main body 620 is located on the whole of the second branch portion 613 . In addition, the first branch portion 612 and the connection portion 615 also include hollow gaps, the first branch portion 612 can be used to avoid, for example, earphone jacks, microphones, etc., and the gap of the connection portion 615 can be used to avoid, for example, speakers.

[0075] In Embodiment 3, the interval b between the second antenna main body 620 and the top surface of the second branch portion 613 is 0.2 mm, the interval c between the extension portion 616 and the second branch portion 613 is 15 mm, and the second antenna The distance d between the main body 620 and the extension 616 is 2...

Abstract

The invention discloses a mobile terminal antenna and a mobile terminal. The mobile terminal antenna includes: a first antenna body, including: a base, a first branch, a second branch and a bending part; the first branch and the second branch The branches are all located on one side of the extension direction of the base, the second branch is located between the first branch and the bending part, any one of the first branch and the second branch is provided with an antenna site, and the other is The antenna feed point is provided; the bending part is located on the other side of the extension direction of the base, and includes a connection part connected with the base part and an extension part connected with the connection part and extending to one side; the second antenna body has a predetermined The spacer is provided parallel to the extension, and the second antenna body is provided with a contact for grounding or connecting to a tuner. The mobile terminal antenna of the present invention is an antenna with balanced performance for both left and right hands in the whole frequency band.

Description

technical field [0001] The present invention relates to a communication device, in particular to a mobile terminal antenna and a mobile terminal. Background technique [0002] The current communication industry has formed a situation where 2G\3G\4G coexist. The mobile terminal communication signal transmission is transmitted through a certain frequency, and the network standards and frequencies owned by each operator are not the same, which requires the mobile terminal to have Ability to work in multiple frequency bands. The communication frequency band of the mobile terminal includes, for example, low frequency (LB): 704-960 MHZ, medium frequency (MB): 1710-2170 MHZ, and high frequency (HB): 2300-2690 MHZ. The ability to operate in these multiple frequency bands requires an antenna structure capable of handling all of these frequencies. [0003] Moreover, the mobile terminal needs to satisfy users with good call quality when holding the call with their left or right hands...
