At the wavelength, two hot spots will be formed around the feed section 131 and the ground section 33, and the antenna design of the double hot spot will make the specific absorption rate measured by the high frequency line 13 lower than 1.6 mW/g. Furthermore, when the distance 馈 between the feeding end 134 and the grounding end 135 is between the half wavelength and the quarter wavelength of the high frequency band, the feeding section 131 and the grounding section 133 in the high frequency line 13 can be alternatively formed. The bent shape is such that the specific absorption rate measured by the high frequency line 13 幵> is double hot spot 'the frequency line 3' is less than 1.6 mW/g. 9/15 M420861 In addition, the antenna structure 1 can also be formed with a low frequency line 14 so that the antenna structure can be applied to the low frequency band and the high frequency band. Furthermore, the SAR values of the antenna structure 1 measured in the low frequency band and the high frequency band are both less than 1.6 mW/g. The above is only an embodiment of the present invention, and is not intended to limit the scope of the patent.
