Specific embodiment
Each preferred embodiment of the invention is described below with reference to accompanying drawings.It provides referring to the drawings
Description, to help the understanding to example embodiment of the invention as defined by appended claims and their equivalents.It includes side
The various details of assistant's solution, but they can only be counted as illustratively.Therefore, it would be recognized by those skilled in the art that
Embodiment described herein can be made various changes and modifications, without departing from scope and spirit of the present invention.Moreover, in order to
Keep specification more clear succinct, by omission pair it is well known that the detailed description of function and construction.
Firstly, the summary that antenna tuning method according to an embodiment of the present invention will be described referring to Fig.1.The antenna tuning side
Method is applied to an electronic equipment.For example, the electronic equipment can be mobile phone, tablet computer etc..The electronic equipment includes day
Line unit and antenna tuning unit.As shown in Figure 1, described method includes following steps.
Firstly, determining the working frequency range of the electronic equipment in step S101.
Next, processing proceeds to step S102.In step S102, according to the working frequency range, determine that the electronics is set
The multiple candidate matches values for the antenna tuning unit for including in standby.It is pointed out here that in open cycle system frequency range with
The correspondence table of matching value is similar, in antenna tuning method according to an embodiment of the present invention, also pre-sets such correspondence
Table.The difference is that there are multiple candidate matches values and a working frequency range phase in corresponding table according to an embodiment of the present invention
It is corresponding.
The quantity of the candidate matches value can be determined according to control precision and processing speed.Specifically, such as fruiting period
It hopes control precision higher, then needs to be arranged more candidate matches value.If it is desire to processing speed is very fast, then need to be arranged less
Candidate matches value.As it can be seen that control precision and processing speed are two conflicting consideration factors.Therefore, candidate matches value
Selection be for control precision and processing speed compromise.For example, the quantity of candidate matches value can be 2~5.
Then, in step S103, it is based on pre-defined rule, selects optimum matching point in the multiple candidate matches value.This
In optimum matching point be to consider currently practical wireless environment (for example, influence, base station or AP of the head hand to antenna are in
Influence etc. when electronic equipment different direction) on the basis of and select.
Finally, the antenna tuning unit is arranged with the optimum matching point in step S104.
As it can be seen that in antenna tuning method according to an embodiment of the present invention, it is pre- for the current working frequency range of electronic equipment
If multiple candidate matches values, then optimal value is selected to be configured in this multiple candidate matches value.In this way, having taken into account open loop
With the function of closed loop, it may be assumed that taken into account in open cycle system and pass through in matching and closed-loop system by the plain mode tabled look-up
Complicated calculations mode based on practical operation situation is matched, that is to say, that based on real among preset candidate matches value
Border operating condition selects optimal value, to improve control essence in the case where effectively reducing cost and effectively improving reflection speed
Degree.
Next, the specific embodiment that step S103 will be described referring to Fig. 2.As shown in Fig. 2, as an example, base
In pre-defined rule, select to specifically comprise the following steps the step of optimum matching point in the multiple candidate matches value.
Firstly, in step S201, the antenna tuning unit is set using each of the multiple candidate matches value
And obtain the signal parameter of the electronic equipment at this time.For example, described in a setting in the multiple candidate matches value
After antenna tuning unit, sample record is carried out by the signal received to the electronic equipment described under this setting, and such as
This signal parameter of sample record obtained as the electronic equipment at this time.For example, the signal parameter can be the electricity
The signal strength that sub- equipment receives.But the present invention is not limited to this.It will be understood to those skilled in the art that any
Other signal parameters that can characterize the performance for wireless communications of the electronic equipment can be suitably applied to the present invention.
Then, in step S202, compare the multiple signal parameters for corresponding respectively to the multiple candidate matches value, and select
Optimum signal parameter out.For example, signal is strong if the signal parameter is the signal strength that the electronic equipment receives
The maximum signal parameter of angle value is optimum signal parameter.
Finally, in step S203, using the corresponding candidate matches value of the optimum signal parameter as the antenna tuning list
The optimum matching point of member.
Certainly, embodiment shown in Fig. 2 is merely illustrative, and the present invention is not limited to this.Those skilled in the art
Member select optimum matching point in the multiple candidate matches value it is appreciated that any other pre-defined rule can also be based on,
If any other pre-defined rule it can be considered that antenna element actual operating state.
In addition, electronic equipment receives it is to be herein pointed out premise of the invention is the assumption that in a short period of time
Signal be constant, it may be assumed that the working frequency range of electronic equipment is constant, and wireless environment locating for electronic equipment is also not
Become.By the working frequency range of electronic equipment is constant and electronic equipment locating for wireless environment constant period be defined as S.Example
Such as, S can be 1~5 second.Based on this it is assumed that executing the step for determining the working frequency range of the electronic equipment as interval using period S
Suddenly.Also, with each that the shorter period (for example, being defined as V) is the multiple candidate matches value of interval use
The antenna tuning unit is arranged.For example, V can be 10 milliseconds.Under normal conditions, period V is arranged far smaller than
Period S, farthest to shorten the period of determining optimum matching point.
In addition, it is also assumed that one greater than period S period SR during, wireless environment locating for electronic equipment is constant,
Or it is almost unchanged.Referring back to Fig. 1, the processing from step S101 to step S104 can regard the basic of a matching value setting as
Processing sequence.Primary such basic handling sequence is re-executed every period SR needs, so as to next best match
Optimum matching point before value replacement.
Alternatively, it is highly preferred that still monitoring the variation of working frequency range during period SR.As long as during period SR
Working frequency range does not change, the optimum matching point selected before just continuing to use.For example, can be during period SR, with the time
Section S is that interval executes the processing for determining whether the working frequency range of the electronic equipment changes.If it is determined that the electronics is set
Standby working frequency range not yet changes, then further determines whether to have already been through period SR.If not yet passing through the time
Section SR, then without extra process.If having already been through period SR, illustrate that wireless environment locating for electronic equipment has very much
It may change, it is therefore desirable to optimum matching point be selected based on current working frequency range again.That is, repeating the above
Based on the processing of current working frequency range selection optimum matching point, before then being replaced using the optimum matching point of newest determination
Optimum matching point.If it is determined that the working frequency range of the electronic equipment has occurred and that change, then according to the work frequency of the change
Section is repeated the above determination candidate matches value, selection optimum matching point and is arranged with the optimum matching point of newest determination
The processing of tuning.
It is pointed out here that setting period SR > S is even arranged in tolerable range
SR > > S is to preferably take into account processing speed.Certainly, if SR is arranged longer, controlling precision will be got over
It is low, but processing speed can be faster.If SR is arranged shorter, controlling precision will be higher, but processing speed can be slower.
The theoretical minimum value of SR can be set to be equal to S.In this case, antenna tuning method according to the present invention is very similar to
Closed loop antenna tuning methods.Although precision is high, reflection speed is slow.Therefore, with the candidate matches value quantity above
Setting it is similar, the setting of SR here also for control precision and processing speed compromise.
For example, period SR can be 10 minutes.Within ten minutes, if the network settings such as working frequency range and channel not
Become, is maintained for the optimum matching point selected.That is, within 10 minutes periods, no matter nothing locating for electronic equipment
Whether thread environment changes, and all thinks that its is constant.In this case, compared with closed loop antenna tuning methods, due to not having at any time
In response to wireless environment slight change and adjust matching value, therefore control accuracy decline.But due to not needing continually to adjust
Whole matching value, therefore reflect speed faster.Also, since the selection of initial matching value considers actual environment factor,
Solves the influence of environmental factor bring to a certain extent on the basis of guaranteeing speed.
Hereinbefore, antenna tuning method according to an embodiment of the present invention is described in detail referring to Figures 1 and 2.Next,
Electronic equipment according to an embodiment of the present invention will be described referring to Fig. 3.
Fig. 3 is to show the functional block diagram of the configuration of electronic equipment according to an embodiment of the present invention.As shown in figure 3, institute
Stating electronic equipment 300 includes: transmitting unit 301, antenna element 302, antenna tuning unit 303, working frequency range determination unit
304, candidate matches value determination unit 305, selecting unit 306 and control unit 307.
Transmitting unit 301 emits signal with specific frequency.The signal that antenna element 302 emits the transmitting unit 301
It is radiated the external world.Antenna element 302 is exactly radiation and reception nothing as indispensable a part, basic function is wirelessly communicated
Line electric wave.When transmitting, antenna element 302 is electromagnetic wave high frequency current transitions；When reception, antenna element 302 turns electromagnetic wave
It is changed to high-frequency current.
Antenna tuning unit 303 is set between the transmitting unit 301 and the antenna element 302.Such as above institute
It states, the matching between transmitting unit and antenna element is a critically important problem.Match well, efficiency of transmission is high.Match it is bad,
Transmission efficiency is low.The output impedance of transmitting unit and the equivalent impedance of antenna element are usually unmatched, higher to guarantee to have
Efficiency of transmission, be generally all connected to one between transmitting unit and antenna element and match resonant tank, i.e. antenna tuning unit
303.Transmitting unit 301 is matched with antenna element 302 by the adjustment of the parameter to antenna tuning unit 303.In short, day
Line tuned cell 303, will be described for carrying out impedance matching between the transmitting unit 301 and the antenna element 302
Antenna element 302 be tuned to designated frequency band.
Working frequency range determination unit 304 is used to determine the working frequency range of the transmitting unit 301.
The working frequency range that candidate matches value determination unit 305 is determined according to the working frequency range determination unit 304 determines
Multiple candidate matches values of the antenna tuning unit 303.In electronic equipment according to the present invention, work frequency is pre-set
Section with the corresponding table of candidate matches value.For example, the corresponding table is stored in advance in a memory (not shown in Fig. 3).It is candidate
Matching value determination unit 305 is corresponding come the working frequency range for determining with currently determining by inquiring the pre-stored correspondence table
Multiple candidate matches values.
As mentioned above it is possible, can determine the quantity of the candidate matches value according to control precision and processing speed.Tool
For body, if it is desired to control that precision is higher, then need to be arranged more candidate matches value.If it is desire to processing speed is very fast,
Then need to be arranged less candidate matches value.As it can be seen that control precision and processing speed are two conflicting consideration factors.Cause
This, the selection of candidate matches value is the compromise for controlling precision and processing speed.For example, the quantity of candidate matches value can be
2~5.
Selecting unit 306 is based on pre-defined rule, selects optimum matching point in the multiple candidate matches value.Here most
Good matching value is to consider currently practical wireless environment (for example, influence, base station or AP of the head hand to antenna are set in electronics
Influence etc. when standby different direction) on the basis of and select.
The antenna tuning list is arranged with the optimum matching point that the selecting unit 306 is selected in control unit 307
Member 303.
As it can be seen that in electronic equipment according to an embodiment of the present invention, it is default for the current working frequency range of electronic equipment
Then multiple candidate matches values select optimal value to be configured in this multiple candidate matches value.In this way, having taken into account open loop and having closed
The function of ring, it may be assumed that taken into account in open cycle system and pass through in matching and closed-loop system by the simple corresponded manner tabled look-up
Complicated calculations mode based on practical operation situation is matched, that is to say, that based on real among preset candidate matches value
Border operating condition selects optimal value, to improve control essence in the case where effectively reducing cost and effectively improving reflection speed
Degree.
Specifically, the antenna is arranged using each of the multiple candidate matches value in described control unit 307
Tuned cell 303 and the signal parameter for obtaining the electronic equipment at this time.For example, in described control unit 307 with the multiple
After one in the candidate matches value setting antenna tuning unit 303, by a sampling unit (in Fig. 3 not shown) to
The signal that the electronic equipment receives under this setting carries out sample record, and using the sample record so obtained as institute at this time
State the signal parameter of electronic equipment.For example, the signal parameter can be the signal strength that the electronic equipment receives.But
It is that the present invention is not limited to this.It will be understood to those skilled in the art that any other can characterize the electronic equipment
The signal parameter of performance for wireless communications can be suitably applied to the present invention.
The selecting unit 306 compares the multiple signal parameters for corresponding respectively to the multiple candidate matches value, and selects
Optimum signal parameter out.For example, if the signal parameter is the signal strength that the electronic equipment receives, selection letter
Number maximum signal parameter of intensity value is as optimum signal parameter.
Finally, described control unit 307 is using the corresponding candidate matches value of the optimum signal parameter as the antenna tune
The optimum matching point of humorous unit 303.
In addition, as mentioned above it is possible, premise of the invention is the assumption that in a short period of time, the received letter of electronic equipment
It number is constant, it may be assumed that the working frequency range of electronic equipment is constant, and wireless environment locating for electronic equipment is also constant
's.By the working frequency range of electronic equipment is constant and electronic equipment locating for wireless environment constant period be defined as S.For example, S
It can be 1~5 second.Based on this it is assumed that working frequency range determination unit 304, which is executed using period S as interval, determines that the electronics is set
The step of standby working frequency range.Also, control unit 307 is that interval uses with the shorter period (for example, being defined as V)
The antenna tuning unit is arranged in each of the multiple candidate matches value.For example, V can be 10 milliseconds.Usual situation
Under, far smaller than period S is arranged to obtain in period V, farthest to shorten the period of determining optimum matching point.
In addition, as mentioned above it is possible, it is also assumed that one greater than period S period SR during, locating for electronic equipment
Wireless environment is constant or almost unchanged.It is single to determine that working frequency range, candidate matches value determine from working frequency range determination unit 304
Member 305 determines that candidate matches value, selecting unit 306 select optimum matching point to set to final control unit 307 with optimum matching point
The processing for setting antenna tuning can regard the basic handling sequence of matching value setting as.It needs to re-execute one every period SR
Secondary such basic handling sequence, so as to the optimum matching point before the replacement of next optimum matching point.
Alternatively, it is highly preferred that working frequency range determination unit 304 still monitors the variation of working frequency range during period SR.
As long as working frequency range does not change during period SR, the optimum matching point of selection before control unit 307 is continued to use.Example
Such as, during period SR, working frequency range determination unit 304 executes the work for determining the electronic equipment using period S as interval
Make the processing whether frequency range changes.If working frequency range determination unit 304 determines the working frequency range of the electronic equipment still
It does not change, then needs further to determine whether to have already been through period SR via a timer (being not shown in Fig. 3).
If timer, which determines, not yet passes through period SR, without extra process.If timer determination has already been through the time
Section SR, then illustrate that wireless environment locating for electronic equipment has probably changed, therefore electronic equipment needs to be based on again to work as
Preceding working frequency range selects optimum matching point.It is selected that is, repeating the above selecting unit 306 based on current working frequency range
The processing of optimum matching point is selected, best before then control unit 307 is replaced using the optimum matching point of newest determination
With value.If working frequency range determination unit 304 determines that the working frequency range of the electronic equipment has occurred and that change, change according to this
The working frequency range of change repeats the above candidate matches value determination unit 305 and determines candidate matches value, selecting unit 306
Select optimum matching point and control unit 307 with the processing of the optimum matching point setting tuning of newest determination.
Here, as mentioned above it is possible, it is in order to more that even SR > > S, which is arranged, in tolerable range in setting period SR > S
Take into account processing speed well.Certainly, if SR is arranged longer, controlling precision will be lower, but processing speed can be faster.
If SR is arranged shorter, controlling precision will be higher, but processing speed can be slower.The theoretical minimum value of SR can be set
It obtains and is equal to S.In this case, antenna tuning method according to the present invention is very similar to closed loop antenna tuning methods.Although
Precision is high, but reflects that speed is slow.Therefore, similar with the setting of candidate matches value quantity above, SR is set here
Set the compromise also for control precision and processing speed.
For example, period SR can be 10 minutes.Within ten minutes, if the network settings such as working frequency range and channel not
Become, is maintained for the optimum matching point selected.That is, within 10 minutes periods, no matter nothing locating for electronic equipment
Whether thread environment changes, and all thinks that its is constant.In this case, compared with closed loop antenna tuning methods, due to not having at any time
In response to wireless environment slight change and adjust matching value, therefore control accuracy decline.But due to not needing continually to adjust
Whole matching value, therefore reflect speed faster.Also, since the selection of initial matching value considers actual environment factor,
Solves the influence of environmental factor bring to a certain extent on the basis of guaranteeing speed.
