Specific embodiment
With reference to the accompanying drawings and examples the present invention is described in further detail.
As depicted in figs. 1 and 2, in order to make it easy to understand, being defined to each view first, in wherein Fig. 1, sign B is for just
Face, in Fig. 2, sign A is the back side, and sign C is right flank, and sign D is downside, and sign E is left surface, and sign F is upper side,
When mobile terminal has antenna, FCC and CE certifications are all made that compulsive requirement to the radiation index S AR value of antenna pair human body.
Authentication specifications require SAR value of the test bag containing left and right, upper and lower side and the back side, and front be give tacit consent to do not test (more than 7
Very little or comprising more than 7 cun of flat board front is acquiescence accident).For left and right, upper and lower side and the back side, depending on antenna
Which face position determining finally to need to test, but generally the back side is essential to test.For FCC certifications,
The back side needs to should be in measuring distance and test under the distance of 0mm (directly contact model) (0mm body SAR).For CE certifications
For, the back side needs to should be in measuring distance and test under the distance of 5mm (directly contact model) (5mm body SAR).Typically right
For the antenna of communication, there is dividing for low frequency (699-960MHz) and high frequency (1710-2690MHz), we are in substantial amounts of work
Find in journey practice, the SAR value of low frequency will generally be less than the SAR value of high frequency, and in high frequency, with the increase of frequency, SAR value
Also there is increase trend.This directional diagram with antenna at different frequencies is relevant, and in low frequency, the directivity of antenna is poor, almost
Omnidirectional radiation, and in high frequency, high directivity, the energy of antenna are concentrated in a direction and radiate, and thus result in local SAR
It is worth higher phenomenon.
