Specific embodiment
Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to
When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment
Described in embodiment do not represent all implementations consistent with this disclosure.On the contrary, they be only with it is such as appended
The example of the consistent device and method of some aspects be described in detail in claims, the disclosure.
Fig. 1 is a kind of flow chart of the control method of mobile terminal antenna shown according to an exemplary embodiment, such as Fig. 1
Shown, the control method of the mobile terminal antenna is used for mobile terminal, method includes the following steps:
In a step 101, the antenna return loss according to the antenna module of mobile terminal under current tranmitting frequency obtains
First reflection coefficient of the antenna module under current tranmitting frequency, the antenna return loss are the reflection power of the antenna module
With the ratio of input power.
Illustratively, mobile terminal takes the mobile phone as an example, and handset emissions signal is input to antenna, and singal source resistance is generally 50 Europe
Nurse, since antenna is generally non-50 ohmic state, so impedance mismatching to a certain degree is had, radio signal transmission middle impedance mismatch
The ratio of the certain power reflection characteristic of Shi Huiyou, reflection power and input power is the antenna return loss, the antenna echo
Loss can take dB value, as antenna reflection coefficient S11 parameter, therefore can be by detecting the input power of antenna and reflecting function
Rate value determines antenna S11 parameter value.Wherein, it should be noted that S11 parameter is in the S parameter i.e. scattering parameter of antenna
One, S11 parameter usually indicates (input) reflection coefficient of antenna, for indicating input return loss characteristic.The parameter indicates
The emission effciency of antenna, S11 parameter value is bigger, indicates that the reflected energy of antenna itself is bigger, the efficiency of such antenna is just
It is poorer.
In a step 102, according to first reflection coefficient, determine that the current state of the mobile terminal, the state include: use
Family use state or contribution ratios test mode.
Illustratively, S11 parameter definition of the mobile phone under free space (Free Space, FS) state is the original S11 of antenna,
When have holding or other have a significant effect state to antenna, the S11 parameter of antenna can change, and respective antenna performance can also drop
Low, ambient conditions are bigger on antenna influence, and S11 Parameters variation is bigger, and antenna performance reduces more.Since mobile phone is in free space
Very big with the S11 parameter difference under user's use state, which may include that holding state and head are held
(Beside Head Hand, BHH) state, it includes that head left hand holds state which, which holds (Beside Head Hand, BHH) state,
(Beside Head Hand Left, BHHL) and the head right hand hold state (Beside Head Hand Right, BHHR).
It is obtained according to emulation experiment, mobile phone is very big in free space and the S11 parameter difference under holding state respectively.?

Between be provided with manikin, anthropoid tissue fluid is placed in the people's body Model, there is automatic prober in the inside, which can be
The various electromagnetic datas of mobile monitoring in manikin, obtain SAR value finally by computer, as test result.Due into
When wardrobe portion SAR is tested primary antenna in mobile phone lower part far from head, S11 parameter is influenced it is unobvious, when carrying out body SAR test
Shi Yaoqiu mobile phone is apart from body at least 5mm or more, so influencing on S11 parameter also unobvious.Therefore, it is surveyed when mobile phone is in SAR
When examination state, antenna for mobile phone S11 parameter can pass through current S11 closer to the S11 parameter under free space state
Parameter is come to determine the mobile terminal currently be user's use state or SAR test mode.
In step 103, when determining the mobile terminal is the contribution ratios test mode, the hair of the mobile terminal is reduced
Penetrate power.
At step 104, when determining the mobile terminal is user's use state, the transmitting function of the mobile terminal is improved
Rate.
Illustratively, for SAR index, international market Europe CE accepted standard is 2.0W/Kg, the mark that U.S. FCC is used
Standard is 1.6W/Kg, and international operator there are certain requirements TRP at hand again, therefore when the determining mobile terminal is SAR survey
When examination state, the transmission power of mobile terminal is reduced, so that SAR index can satisfy the requirement of testing standard, when determining the shifting
Dynamic terminal is user's use state, and the transmission power of mobile terminal can be improved at this time, to meet the needs of TRP, reduce to
The experience at family influences.
Above technical scheme, by obtaining first reflection system of the antenna module of the mobile terminal under current tranmitting frequency
Number；According to first reflection coefficient, the current state of the mobile terminal is determined；When determine the mobile terminal for the contribution ratios survey
When examination state, the transmission power of the mobile terminal is reduced；When determining the mobile terminal is user's use state, the shifting is improved
The transmission power of dynamic terminal.The disclosure can satisfy the requirement of SAR test request and the correct chiral energy of user.

Illustratively, in laboratory, emulation experiment is first passed through in advance, and (b and Fig. 2 c referring to fig. 2, wherein Fig. 2 b is in laboratory
The analogue simulation head right hand holds status diagram, and Fig. 2 c is that analogue simulation head left hand holds status diagram in laboratory；) obtain the hand
Machine tranmitting frequency is at 0 to 3GHz, which holds state BHHL in free space FS state, head left hand respectively and the head right hand is held
S11 under state BHHRFS、S11BHHL、S11BHHRCurve, (d referring to fig. 2, Fig. 2 d be in laboratory mobile phone respectively in free space
With the simulation result curve graph of S11 parameter under head holding state；) according to the current frequency of the mobile phone and above-mentioned curve, it determines
Under current tranmitting frequency, corresponding S11FSThe parameter value of curve is the second reflection coefficient parameter value；Corresponding S11BHHLOr
Person S11BHHRThe parameter value of curve is the third reflection coefficient parameter value.The third reflection coefficient parameter value can be S11BHHLWith
S11BHHRIn larger or one lesser (or can also be averaged).It is alternatively possible to will be real before mobile phone factory
The above-mentioned emulation data that free space FS state, head are held under state BHH within the scope of the indoor certain frequency being obtained ahead of time are tested to deposit
Enter in the mobile phone；The policy data can also be obtained in real time after mobile phone factory, and stored.
