It should be noted that in the present embodiment, the radiofrequency signal of generation is that electronic equipment is currently able to complete normally
The radiofrequency signal of network communication.
In step s 102, the radiofrequency signal that detection antenna does not give off.
In a wireless communication system, the high-frequency current energy generated by radio circuit is transmitted to transmitting day by feeder line
High-frequency current energy is converted polarized electromagnetic wave energy by line, antenna, and the direction emitted is being needed to launch, simple next
It says, the electromagnetic wave launched is exactly radiofrequency signal.
It is understood that antenna is during emitting radiofrequency signal, since electromagnetic wave is in antenna system different piece
Impedance can be encountered, therefore antenna can not completely go out emission of radio frequency signals, some radiofrequency signal cannot give off
It goes, this portion radio frequency signal can reflect, and then be detected by the vector power detection module in circuit.
In one embodiment, during electronic equipment carries out network communication, signal can be conveyed by antenna, when defeated
Sending the frequency to the signal of antenna is not resonance frequency required for current network communicates, and just will appear impedance.
In step s 103, the power and frequency information of the radiofrequency signal not given off are obtained；
It is understood that the radiofrequency signal not given off is analyzed by the vector power detection module in circuit,
The frequency and power of non-radiation signal, and the strength vector network of non-radiation signal are obtained, meanwhile, vector power analysis module
The radiofrequency signal currently exported can also be analyzed, obtain the letter such as strength vector network, power and frequency of radiofrequency signal

To improve the intensity of radiofrequency signal, the quality of terminal network communication is improved.
Referring to Fig. 2, Fig. 2 is the second procedure schematic diagram of adjustable signal frequency approach provided by the embodiments of the present application, it should
Method is applied to electronic equipment, specifically includes the following steps:
In step s 201, radiofrequency signal required for network communication is generated, and radiofrequency signal is gone out by aerial radiation.
When region of the electronic equipment locating for it is switched on, by search for networks, the communications band of current region is obtained, so
Afterwards according to the communications band, the radiofrequency signal that electronic equipment carries out proper network communication is generated, and passes through antenna penetrating generation
Frequency signal radiation is gone out.
For example, the mobile phone to have shut down after powering, can be according to phonecard or ESIM card built-in in mobile phone in the area A
(Embedded-SIM, embedded SIM card) searches carrier service network corresponding to the card, if phonecard is
The phonecard of " China Mobile " then searches " China Mobile " in the area A and carries out communications band provided by Network communication service, so
Mobile phone generates radiofrequency signal according to the frequency range afterwards, is launched by antenna and carries out normal network communication.
In step S202, the radiofrequency signal that antenna does not give off is detected.
During electronic equipment carries out network communication, signal can be conveyed by antenna, when the letter for being delivered to antenna
Number frequency be not current network communicate required for resonance frequency, just will appear impedance.At this point, antenna is in transmitting radiofrequency signal
When, just having portion radio frequency signal cannot launch.
For example, mobile phone is 850MHz in the communications band that a-quadrant uses, user holds mobile phone and needs B area, in the area B
The network communication frequency range in domain, operator used in mobile phone is 900MHz, at this point, antenna is not in best radiation regimes, spoke
The signal strength of injection is inadequate, needs to detect the radiofrequency signal not radiateing at this time, in a subsequent step, to mobile phone day
The resonance frequency of line is adjusted, and antenna is made to be in best radiation regimes.
It is understood that there are many modes that detection antenna for mobile phone does not radiate, for example, passing through the vector power in mobile phone
Detection chip, or detected by the control platform in mobile phone, with no restriction to the application at this.
In step S203, the information such as power and the frequency of the radiofrequency signal not given off are analyzed.This step and step
The embodiment recorded in S103 is identical, is not repeated explanation herein.
In step S204, judge whether the RF signal strength not given off is greater than default RF signal strength.
Since the communications band of different regions and different operators is different, by different operators in different regions
Communications band be acquired, then simulate these communications bands in the lab, keep the electronic equipments such as mobile phone, smartwatch logical
It crosses these communications bands and carries out network communication, mobile phone is when corresponding communications band carries out network communication, by the spoke of antenna for mobile phone
The state of penetrating is adjusted to a preset state, and the aerial radiation under preset state can guarantee that the normal table of mobile communication uses, or
Person's preset state may be the optimum state of aerial radiation.The radiofrequency signal that antenna for mobile phone is launched at this time understands some not
It radiate, under preset aerial radiation state, the RF signal strength not given off is detected, by this RF signal strength
It is set as presetting non-radiated radio frequency (RF) signal strength, certainly, such set-up mode Just One Of Those Things can also be set by other means

In one embodiment, mobile phone is after the information for testing and analyzing out non-radiated radio frequency (RF) signal, then by baseband chip or
Person's control platform calculates the intensity for the radiofrequency signal not radiated, by the intensity of the calculated radiofrequency signal not radiated with
RF signal strength is preset under the communications band to compare.If the RF signal strength not radiated is not more than preset radio frequency
Signal strength thens follow the steps S208, is adjusted without the resonance frequency to antenna；If the RF signal strength not radiated is big
In preset RF signal strength, S205 is thened follow the steps, is further judged.
In step S205, judge whether the resonance frequency of antenna is equal to radiation signal frequency.
After the intensity for judging non-radiation signal is greater than preset intensity, mobile phone is worked as by baseband chip or controller
Communication frequency used in preceding communications band is obtained, in addition, the resonance frequency to antenna obtains, the mode of acquisition can
According to formula:
Wherein F is the resonance frequency of antenna, and L is inductance, and C is adjustable condenser, and x is different antenna resonant frequency mark
Number.By obtaining the specific value of adjustable condenser in circuit, the resonance frequency of antenna is calculated.
After getting the resonance frequency of antenna, the resonance frequency of antenna and communication frequency are compared, judge antenna
Resonance frequency whether be equal to communication frequency, if the two is equal, then follow the steps S208, without the resonance frequency to antenna into
Row adjustment.If the two is unequal, S206 is thened follow the steps.
In step S206, capacitor is adjusted according to the information analyzed makes the resonance frequency of antenna change.
When judging the resonance frequency and unequal radiation signal frequency of antenna in step S205, at this time by controller or
Person's baseband chip is adjusted the capacitance in circuit, according to formula:
Wherein F is the resonance frequency of antenna, and L is inductance, and C is adjustable condenser, and x is different antenna resonant frequency mark
Number.The resonance frequency of antenna for mobile phone is adjusted, until the antenna resonant frequency of adjustment is equal with communication frequency, or at this time
Antenna resonant frequency very little is differed with communication frequency, at this time the resonance frequency of antenna be optimum resonant frequency, it is current in mobile phone
Under locating communications band, relative to original antenna resonant frequency, signal strength that antenna resonant frequency at this time gives off
Most strong, when mobile phone carries out network communication, communication quality is best.
In step S207, launch best radiofrequency signal adjusted.
By above-mentioned steps treated radiofrequency signal, antenna can be made to reach optimum frequency, at this time the resonance frequency of antenna
Rate is equal to communication frequency, and the signal that handset antenna radiation goes out is strong relative to unadjusted radiofrequency signal, the network communication matter of mobile phone
Amount is also promoted.
In conclusion can generate required radiofrequency signal when communication when terminal carries out network communication, then pass through day
Line is launched, but has the radiofrequency signal that part is not radiate and reflect, and passes through the detection to non-radiation signal point
Analysis, obtains the information such as its power and frequency, calculates the intensity for not giving off signal, by its with preset RF signal strength into
Row comparison obtains present communications frequency range if the RF signal strength not given off is greater than preset RF signal strength
Communication frequency, whether the antenna resonant frequency for calculating terminal is equal to communication frequency, can in circuit by adjusting if differed
The numerical value for adjusting capacitor makes the radiation frequency of antenna be equal to communication frequency, antenna is made to be in optimal radiation regimes, promotes radio frequency
The intensity of signal improves quality when terminal carries out network communication.

It includes:
In step S301, adjustable condenser is in original state.
It is understood that the frequency that mobile phone can adjust radiofrequency signal makes hand when the communication network of mobile phone changes
Machine can be normally carried out network communication, and when not adjusting the frequency of radiofrequency signal, adjustable condenser at this time is in original state.
For example, the communication network frequency range of mobile phone needs from A frequency range to change B frequency range into, antenna for mobile phone resonance frequency in A frequency range at this time
Rate is F1, and the resonance frequency of B frequency range antenna for mobile phone is F2, in switching communication frequency band not yet, in the corresponding circuit of F1 can
Adjusting capacitance values are initial value, and adjustable condenser at this time is in original state.
In step s 302, switch communication frequency, adjustable condenser value increases.
When entering different communications bands, mobile phone needs to switch communication frequency, at this time first increases adjustable condenser value,
To make the resonance frequency of antenna change.
In step S303, the reduction when radiofrequency signal not given off reflects.
When radio frequency number is by aerial radiation, having portion radio frequency signal cannot be radiate, thus reflect, if
The communication frequency that antenna resonant frequency deviates switching is remoter, and the signal radiateing is fewer, i.e., reflected signal is bigger, leads to
Believe frequency it can be appreciated that antenna radiation signal frequency.
If the reflected signal strength of the radiofrequency signal not given off at this time is being reduced, can continue to adjust capacitor
Value.
In step s 304, continue to increase tunable capacitor capacitance, until reflected signal cannot be reduced.
Continue to increase tunable capacitor capacitance, reflected signal will continue to reduce, and illustrate that the signal radiateing is strong
Degree is higher, reflected less, until illustrating the resonance frequency of antenna herein when reflected signal does not continue to reduce
It has been under communications band most preferably, antenna is in best radiation regimes.
In step S305, the increase when radiofrequency signal not given off reflects.
If increasing the capacitance of tunable capacitor when switching another communications band, the radiofrequency signal not given off at this time
Increase when reflecting then illustrates to need to do capacitance reduction processing.
In step S306, reduce tunable capacitor capacitance, until reflected signal cannot be reduced.
Reduce tunable capacitor capacitance, reflected signal will continue to reduce, illustrate the signal strength radiateing compared with
Height, it is reflected less, until illustrating that the resonance frequency of antenna communicates herein when reflected signal does not continue to reduce
It has been under frequency range most preferably, antenna is in best radiation regimes.
In conclusion having different communication frequencys, i.e. the radiation signal frequency of antenna when mobile phone switches different frequency range
Rate needs to make adjustment to the capacitance of tunable capacitor at this time, makes antenna reflected signal reduction when emitting radiofrequency signal
To that cannot be further continued for reducing, then antenna resonant frequency at this time is optimal, the radiation regimes of antenna in present communications frequency range
It is best.
