As a kind of embodiment, the global design length of antenna module is less than or equal to 16mm, and width is less than or waited
In 8mm.Due to current mobile terminal be intended to miniaturization and portability development, antenna it is less and less using space,
Under the conditions of this, the small size design of antenna is necessary.
Wherein, the width in the gap of the 3rd resonant element 143 could be arranged to 0.5mm to 1mm.In theory, slot antenna
Gap width it is wider, its bandwidth is wider, and in the present embodiment, because the global design by antenna module is limited, the 3rd is humorous
The gap width of unit 143 of shaking can be arranged between 0.5mm to 1mm, for example, 0.5mm, 0.7mm or 1mm etc..
Likewise, the gap width between the first resonant element 141 and the second resonant element 162 is 0.5mm to 1mm, example
Such as, gap width is arranged to 0.5mm, 0.7mm or 1mm etc..It is understood that by setting different gap widths, can
To adjust the second frequency band resonance of the second resonant element 162, so as to meet the overall frequency coverage demand of antenna module.
In the present embodiment, by setting the size of the antenna 16 of first antenna 14 and second, and it is humorous by changing the 3rd
Shake unit 143 gap width and the first resonant element 141 and the second resonant element 162 between gap width adjust height
The bandwidth in frequency domain, antenna module is set also to meet the wireless performance in high frequency in the case where saving space-consuming, so as to real
Present low frequency 2.4 is to 2.4835GHz and high frequency 5.150 to 5.850GHz all standing.Fig. 2 and Fig. 3 are referred to, wherein, Fig. 2 is
A kind of structural representation of the embodiment of mobile terminal one of the present invention, Fig. 3 are the partial structurtes signals of the mobile terminal in Fig. 2
Figure.Mobile terminal 20 in the present embodiment includes antenna module 10, wherein, antenna module 10 is any one above-mentioned antenna sets
Part.
Wherein, mobile terminal 20 can be mobile phone, notebook and tablet personal computer etc..
As a kind of embodiment, mobile terminal 20 also includes printed circuit board (PCB) 24 and floor 26；Wherein, first antenna
