Since the antenna feeding position and length are usually restricted by the overall machine design, the antenna impedance is often extreme, and its voltage will be much higher than that of the radio frequency end. When the circuit voltage exceeds the maximum operating voltage of the antenna tuner, the normal operation of the antenna matching will be affected.

[0033] Next, in conjunction with the attached Figures 1 to 15 , the antenna assembly, electronic device, control method, device, and readable storage medium provided by the embodiments of the present application will be described in detail through specific embodiments and their application scenarios.

[0034] In some embodiments of the present application, an antenna assembly is provided. Figure 1 FIG. shows one of the circuit diagrams of the antenna assembly provided in some embodiments of the present application, as Figure 1As shown in the figure, the antenna assembly 100 includes: a radio frequency power amplifier 110; a coupler 120, the coupler 120 includes a first path 121 and a second path 122, the first path 121 is coupled to the second path 122, and a first end of the first path 121 is connected to an output end of the radio frequency power amplifier 110; a switch 130, connected to the second path 122 of the coupler 120, and the switch 130 is used to switch the coupling direction between the first path 121 and the second path 122; a tunable power divider 140, an input end of the tunable power divider 140 is connected to a second end of the first path 121; at least two antennas 150, connected to at least two output ends of the tunable power divider 140; at least two tuners 160, respectively connected to the at least two antennas 150; a controller 170, the controller 170 is connected to the second path 122, the controller 170 is connected to a control end of the switch 130, and the controller 170 is connected to the tunable power divider 140, wherein, in the case where the coupling direction is in reverse coupling, the second path 122 is used to transmit a harmonic power signal to the controller 170, and the controller 170 is used to control the tunable power divider 140 according to the harmonic power signal to adjust the power division ratio corresponding to the at least two antennas 150.

[0035] In the embodiment of the present application, the antenna assembly 100 includes at least two antennas 150, and a tuner 160 is provided for each antenna 150. The radio frequency power amplifier 110 is connected to the at least two antennas 150 through a tunable power divider 140. The tunable power divider 140 can dynamically distribute the transmitted power to the at least two antennas 150, and a coupler 120 capable of collecting harmonic power signals is further provided between the radio frequency power amplifier 110 and the tunable power divider 140. By collecting the harmonic power signals through the coupler 120, the total harmonic power of the at least two antennas 150 can be collected.

[0036] Figure 2 The relationship curve between the capacitance value of the varactor diode and the reverse bias voltage provided in some embodiments of the present application is shown. Figure 3 The relationship curve between the harmonic power of the tuner and the voltage provided in some embodiments of the present application is shown, as Figure 2 and Figure 3As shown, the relationship between the capacitance value of the varactor diode and the reverse bias voltage is that as the voltage increases, the capacitance value shows a non-linear decreasing trend. Due to the non-linear device, when a relatively large voltage is applied to the tuner 160, large harmonics will be generated. That is, as the voltage increases, the harmonic power increases rapidly. If the harmonics of a frequency band happen to fall within the band of another frequency band, harmonic interference will be caused. As the voltage increases, the harmonic power increases exponentially. In the case where the antenna assembly 100 includes multiple antennas 150 and corresponding tuners 160, the harmonic power is dispersed to multiple tuners 160, and the total harmonic is less than the case where the power is concentrated in a single tuner 160, thereby reducing the harmonic components generated by the tuner 160 in the overall antenna assembly 100. Therefore, by reallocating the transmission power of at least two antennas 150 through the adjustable power divider 140, it is possible to reduce the power borne by a single tuner 160 while ensuring the overall transmission power of the antenna assembly 100, thereby alleviating the non-linear effect of a single tuner 160. The overall harmonic components of at least two tuners 160 will be lower than the harmonic components at high transmission power of a single antenna 150.

[0037] Exemplarily, the tuner 160 may be composed of semiconductor devices such as varactor diodes and field effect transistors.

[0038] In the embodiment of the present application, during the operation of the antenna assembly 100, the harmonic power signal is collected through the coupler 120. When it is detected that the harmonic power corresponding to the harmonic power signal exceeds the power threshold, it is determined that the harmonic power is large. At this time, the adjustable power divider 140 is controlled to reallocate the transmission power of at least two antennas 150. While keeping the transmission power of at least two antennas 150 unchanged, the path of the antenna 150 with relatively poor non-linearity among at least two antennas 150 bears less transmission power, thereby reducing the harmonic components generated by the non-linearity of the tuner 160 in the overall antenna assembly 100.

[0039] Specifically, in the scenario where the user actually uses the electronic device, in different scenarios, the grasping position and method of the user on the electronic device are different, which will affect the input impedance of the antenna 150, cause a change in reflection, and may change the voltage borne by the tuner, thereby affecting the harmonic size. Therefore, by setting the coupler 120 in the antenna assembly 100, the harmonic power of the antenna assembly 100 can be monitored, and an adjustable power divider 140 is set in the antenna assembly 100 to dynamically allocate the transmission power of at least two antennas 150 in a timely manner according to the monitoring result of the harmonic power, so as to minimize the harmonics of the antenna assembly 100.

[0040] In the embodiments of the present application, the coupler 120 includes a first path 121 and a second path 122. The first path 121 is connected between the RF power amplifier 110 and the adjustable power divider 140. The second path 122 is connected to the ground terminal and the controller 170 through the switch 130. The switch 130 can be a double-pole double-throw switch. Through the switch 130, the coupling direction between the second path 122 and the first path 121 can be adjusted. When the coupling direction is reverse coupling, the second path 122 can transmit the harmonic power signal to the controller 170, so that the controller 170 can detect the harmonic power generated by at least two antennas 150.

[0041] Specifically, after the controller 170 obtains the harmonic power signal, it can control the adjustable power divider 140 according to the harmonic power signal, convert the harmonic optimization into a general optimization problem, and obtain the optimal solution through a software algorithm.

[0042] Figure 4 FIG. 2 shows the second circuit diagram of the antenna assembly provided in some embodiments of the present application. As Figure 4 shown, the coupler 120 samples the harmonic power signal, transmits the harmonic power signal to the controller 170 through power detection, and the controller 170 outputs a control signal for controlling the adjustable power divider 140 to control the power division ratio of the adjustable power divider 140. Exemplarily, the antenna assembly 100 has a total of N antenna 150 paths, numbered i, with values of 1, 2,..., N, and the power ratio of each antenna 150 path is P i , where P i satisfies the following relationship: That is, the total transmission power is constant, then the generated harmonic power H can be defined. H and P i satisfy the following relationship formula (1):

[0043] H = f(P1, P2,..., P N ); (1)

[0044] where H is the harmonic power, P i is the power division ratio, and f() is the mapping relationship between each group of power division ratios and the harmonic power.

[0045] Due to the limitation of the power division ratio constraint condition , the number of independent variables is N - 1, and the variables are: P1, P2,..., P N-1 , and the expression (2) of P N is as follows:

[0046]

[0047] where P N is the variable in the power ratio, and P i is the power division ratio.

[0048] In the embodiment of the present application, a coupler 120 is provided in the antenna assembly 100. The coupler 120 can detect harmonic power, and a tunable power divider 140 is correspondingly provided. The tunable power divider 140 can adjust the transmission power of each antenna 150. Therefore, while the controller 170 can control the power division ratio of at least two lines through the tunable power divider 140, it can detect the current harmonic power through the coupler 120, and then redistribute the transmission power of at least two antennas 150 through an optimization algorithm. While keeping the transmission power of at least two antennas 150 unchanged, the antenna 150 path with relatively poor linearity among at least two antennas 150 undertakes less transmission power, thereby reducing the harmonic components generated by the nonlinearity of the tuner 160 in the overall antenna assembly 100, and solving the problem of harmonic interference existing in the antenna 150 tuner 160 in the antenna assembly 100.

[0049] Figure 5 One of the circuit diagrams of the switch and the coupler in some embodiments of the present application is shown. Figure 6 Another circuit diagram of the switch and the coupler provided in some embodiments of the present application is shown. As Figure 5 and Figure 6 shown, the switch 130 includes: a first moving contact 131 and a second moving contact 132. The first moving contact 131 is connected to the first end of the second path 122, and the second moving contact 132 is connected to the second end of the second path 122; a first stationary contact 133 and a second stationary contact 134. The first stationary contact 133 is grounded, and the second stationary contact 134 is connected to the controller 170; wherein, when the first moving contact 131 is connected to the first stationary contact 133 and the second moving contact 132 is connected to the second stationary contact 134, the coupling direction is in reverse coupling.

[0050] In the embodiment of the present application, the switch 130 is a double-pole double-throw switch. The switch 130 includes two moving contacts and two stationary contacts. The first moving contact 131 and the second moving contact 132 of the switch 130 are respectively connected to the first end and the second end of the second path 122, and the first stationary contact 133 and the second stationary contact 134 of the switch 130 are respectively connected to the ground terminal and the signal input terminal of the controller 170. The controller 170 can control the first moving contact 131 of the switch 130 to be connected to the first stationary contact 133 or the second stationary contact 134, and control the second moving contact 132 of the switch 130 to be connected to the first stationary contact 133 or the second stationary contact 134.

[0051] As Figure 6 shown, the first path and the second path of the coupler are in reverse coupling.

[0052] Specifically, when the first moving contact 131 is connected to the first stationary contact 133, the second moving contact 132 is connected to the second stationary contact 134. When the first moving contact 131 is connected to the second stationary contact 134, the second moving contact 132 is connected to the first stationary contact 133. Among them, when the first moving contact 131 is connected to the first stationary contact 133 and the second moving contact 132 is connected to the second stationary contact 134, the first path 121 and the second path 122 of the coupler 120 are reversely coupled. Then, the second end of the second path 122 outputs a reversely coupled signal, that is, a harmonic power signal, through the second stationary contact 134 of the switch 130.

[0053] Figure 7 The schematic diagram showing the coupling direction of the coupler 120 provided in some embodiments of the present application is as Figure 7 shown. The arrow A shows the forward coupling direction of the first path 121 and the second path 122 in the coupler 120, and the arrow B shows the reverse coupling direction of the first path 121 and the second path 122 in the coupler 120.

[0054] In the embodiments of the present application, the second path 122 of the coupler 120 is connected to a double-pole double-throw switch, and the controller 170 can control the switch 130 to make the coupling direction of the first path 121 and the second path 122 of the coupler 120 be reverse coupling, so that the harmonic power signal can be sampled through the coupler 120.

[0055] In some embodiments of the present application, when the coupling direction is in forward coupling, the second path 122 is used to transmit the transmitted power signal to the controller 170. Among them, when the first moving contact 131 is connected to the second stationary contact 134 and the second moving contact 132 is connected to the first stationary contact 133, the coupling direction is in forward coupling.

[0056] In the embodiments of the present application, when the coupling direction of the first path 121 and the second path 122 in the coupler 120 is forward coupling, the coupler 120 can collect the transmitted power signals of at least two antennas 150 and transmit the transmitted power signals outward through the second path 122.

[0057] As Figure 5 shown, the first path 121 and the second path 122 of the coupler 120 are forwardly coupled.

[0058] Specifically, the output end of the radio frequency power amplifier 110 is connected to the coupler 120. The forward coupling of the first path 121 and the second path 122 of the coupler 120 is used to detect the transmitted power signal, so as to detect the transmitted powers of at least two antennas 150. The detected transmitted power signal is transmitted to the controller 170, enabling the controller 170 to control the transmitted powers of at least two antennas 150 according to the transmitted power signal. When detecting the harmonic power, the first path 121 and the second path 122 of the coupler 120 are switched to reverse coupling through the double-pole double-throw switch 130 to detect the harmonic power.

[0059] In the embodiment of the present application, the second path 122 of the coupler 120 is connected to the switch 130. The switch 130 can control the coupling direction between the first path 121 and the second path 122 in the coupler 120, so that the coupler 120 can detect the transmitted power signal through the forward coupling of the first path 121 and the second path 122, and can also detect the harmonic power signal through the reverse coupling of the first path 121 and the second path 122.

[0060] As Figure 1 and Figure 4 shown, in some embodiments of the present application, the antenna assembly 100 further includes: a resistor 180. The first end of the resistor 180 is connected to the first stationary contact 133 of the switch 130, and the second end of the resistor 180 is grounded.

[0061] In the embodiment of the present application, the antenna assembly 100 further includes a resistor 180. The resistor 180 is the grounding resistor 180 of the antenna assembly 100. The first stationary contact 133 of the switch 130 is connected to the grounding end through the resistor 180. The second stationary contact 134 of the switch 130 is the signal acquisition port. When the first path 121 and the second path 122 are reversely coupled, the harmonic power signal is output through the second stationary contact 134 of the switch 130. When the first path 121 and the second path 122 are forwardly coupled, the transmitted power signal is output through the second stationary contact 134 of the switch 130, enabling the switch 130 to control the coupler 120 to acquire at least one of the transmitted power signal and the harmonic power signal.

[0062] In some embodiments of the present application, an electronic device is provided. Figure 8 The schematic block diagram of the electronic device provided in some embodiments of the present application is shown. As Figure 8 shown, the electronic device 800 includes: an antenna assembly 100. The antenna assembly 100 is the antenna assembly 100 in any of the above embodiments, and thus has all the beneficial technical effects of the antenna assembly 100 in any of the above embodiments, which will not be elaborated here too much.

[0063] Exemplarily, the electronic device further includes a housing, and the antenna assembly is disposed within the housing.

[0064] In some embodiments of the present application, a control method is provided, which is applied to the electronic device in any of the above embodiments. Figure 9 One of the flowcharts of the control method provided in some embodiments of the present application is shown, as Figure 9 shown, the control method includes:

[0065] Step 902, controlling the switch element to switch the coupling direction between the first path and the second path of the coupler to reverse coupling;

[0066] In this embodiment, the coupler includes a first path and a second path. When the first path and the second path are reversely coupled, the coupler can collect harmonic power signals.

[0067] Specifically, the controller controls the radio frequency front-end device through control instructions. Under normal conditions, the coupler is in a forward coupling state. By switching the switch element, the harmonics reflected by the tuner can be classified and coupled, and sent to the controller for harmonic power detection. After the detection is completed, the first path and the second path of the coupler are controlled by the switch element to be forward coupled, and the forward transmit power detection is restored.

[0068] Step 904, receiving the harmonic power signal output from the second path;

[0069] Step 906, controlling the adjustable power divider according to the harmonic power signal to adjust the power division ratio corresponding to at least two antennas.

[0070] In the embodiments of the present application, during the operation of the antenna assembly, harmonic power signals are collected through the coupler. When it is determined that the harmonic power corresponding to the harmonic power signal exceeds the power threshold, it is determined that the harmonic power is large. At this time, the adjustable power divider is controlled to reallocate the transmit power of at least two antennas, while keeping the transmit power of at least two antennas unchanged, and making the antenna path with relatively poor nonlinearity among at least two antennas bear less transmit power, thereby reducing the harmonic components generated by the nonlinearity of the tuner in the overall antenna assembly.

[0071] Specifically, in the scenario where the user actually uses the electronic device, in different scenarios, the user's grasping position and method of the electronic device are different, which will affect the input impedance of the antenna, cause changes in reflection, and may change the voltage borne by the tuner, thereby affecting the harmonic size. Therefore, by setting a coupler in the antenna assembly, the harmonic power of the antenna assembly can be monitored, and an adjustable power divider is set in the antenna assembly, and the transmit power of at least two antennas is dynamically allocated in a timely manner according to the monitoring result of the harmonic power, so as to minimize the harmonics of the antenna assembly.

[0072] In the embodiments of the present application, the coupler includes a first path and a second path. The first path is connected between the RF power amplifier and the adjustable power divider. The second path is connected to the ground terminal and the controller through a switching element. The switching element can be a double-pole double-throw switch. Through the switching element, the coupling direction between the second path and the first path can be adjusted. When the coupling direction is reverse coupling, the second path can output a harmonic power signal to the controller, enabling the controller to detect the harmonic power generated by at least two antennas.

[0073] Specifically, after the controller obtains the harmonic power signal, it can control the adjustable power divider according to the harmonic power signal, convert the harmonic optimization into a general optimization problem, and achieve the optimal solution through a software algorithm.

[0074] In the embodiments of the present application, a coupler is provided in the antenna assembly. Through the coupler, the harmonic power can be detected, and an adjustable power divider is correspondingly provided. Through the adjustable power divider, the transmission power of each antenna can be adjusted. Therefore, while the controller can control the power division ratio of at least two antennas through the adjustable power divider, it can detect the current harmonic power through the coupler, and thus reallocate the transmission power of at least two antennas through an optimization algorithm. While keeping the transmission power of at least two antennas unchanged, the antenna path with relatively poor nonlinearity among at least two antennas undertakes less transmission power, thereby reducing the harmonic components generated by the tuner nonlinearity in the overall antenna assembly and solving the problem of harmonic interference in the antenna tuner in the antenna assembly.

[0075] Figure 10 The flowchart of the control method of the switching element provided in some embodiments of the present application is shown. As Figure 10 shown, the control method of the switching element includes:

[0076] Step 1002, the controller sets the switching element of the coupler to the reverse coupling state through a control instruction;

[0077] Among them, the control instruction can be a MIPI (Mobile Industry Processor Interface) instruction or a GPIO (General-purpose input / output) instruction.

[0078] Step 1004, the harmonic power signal collected in the reverse coupling state is transmitted to the controller, and the controller obtains the corresponding harmonic power through internal amplification, detection, and sampling;

[0079] Step 1006, the controller sets the switching element of the coupler to the forward coupling state through a control instruction.

[0080] In some embodiments of the present application, the adjustable power divider is controlled according to the harmonic power signal, and the power division ratio corresponding to at least two antennas is adjusted, including: when the first harmonic power value is greater than the power threshold, determining the adjustment gradient of at least two power division ratios, where the first harmonic power value is the power value of the harmonic power signal before adjusting the power division ratio; adjusting at least two power division ratios according to the adjustment gradient and the step coefficient; determining the first power difference between the first harmonic power value and the second harmonic power value, where the second harmonic power value is the power value of the harmonic power signal after adjusting the power division ratio according to the adjustment gradient; and when the first power difference is greater than or equal to the difference threshold, returning to execute the step of determining the adjustment gradient of at least two power division ratios.

[0081] In the embodiments of the present application, the first harmonic power value is the power value of the harmonic signal collected by the coupler before adjusting the power division ratio, that is, the harmonic power value at the current moment. The power threshold is used to determine whether the current harmonic power value is too large. When it is detected that the first harmonic power value is greater than the power threshold, it is determined that the harmonic power is too large at this time, which may affect the operation of at least two antennas. At this time, the harmonic optimization process is started.

[0082] In the embodiments of the present application, the harmonic power is optimized by the gradient descent method. The gradient descent method needs to first determine the adjustment gradient, then adjust at least two power division ratios along the negative gradient, and then determine whether to continue iterative adjustment.

[0083] Specifically, after obtaining the adjustment gradient for adjusting at least two power division ratios, at least two power division ratios are adjusted according to the adjustment gradient and the step coefficient. After the adjustment, the second harmonic power value of the adjusted harmonic power signal is obtained through the coupler, the first harmonic power value is compared with the second harmonic power value to obtain the first power difference, and then the first power difference is numerically compared with the difference threshold. If the first power difference is greater than or equal to the difference threshold, it means that there is still room for optimizing the current power division ratio, and the step of determining the adjustment gradient of the power division ratio is returned to continue iterative optimization of at least two power division ratios according to the newly determined adjustment gradient. If the first power difference is less than the difference threshold, it means that the current power division ratio has reached the optimum, and the complete optimization step is stopped.

[0084] It should be noted that due to the limitation of the adjustable range of hardware devices such as antennas and adjustable power dividers, the power division ratio has an adjustment range. If the power division ratio adjusted by the adjustment gradient exceeds the adjustment range, the boundary value of the adjustment range is taken as the adjusted power division ratio.

[0085] Exemplarily, taking the number of antennas and tuners as 2 as an example, the optimization process of the power division ratio is described as follows:

[0086] If the number of antennas and tuners is 2, then the number of independent variables is only 1. To distinguish the parameters of different iterations, the power split ratio of the t-th iteration is defined as P 1t , and the total harmonic power of the t-th iteration is H t . The initial values are defined as P 10 and H0 respectively. The step coefficient is a, the gradient detection step size is ΔP, and the error of the termination condition is err, that is, the difference threshold is err. For example, the initial power split ratio is set to equal power split, that is, P 10 = 0.5.

[0087] Figure 11 The flowchart of the power split ratio optimization method provided in some embodiments of the present application is shown. As Figure 11 shown, the power split ratio optimization method includes:

[0088] Step 1101, set the initial value of the power split ratio P 10 . Determine the first harmonic power value as H0 through the coupler, and the iteration number t = 1;

[0089] Step 1102, set the power split ratio to P 1(t-1) + ΔP and P 1(t-1) - ΔP, and determine the corresponding harmonic powers as H(P 1(t-1) + ΔP) and H(P 1(t-1) - ΔP) respectively through the coupler, and determine the adjustment gradient as H’ = [H(P 1(t-1) + ΔP) - H(P 1(t-1) - ΔP)] / 2ΔP;

[0090] Among them, ΔP is the gradient detection step size, P 1(t-1) is the power split ratio before adjustment, and H(P 1(t-1) + ΔP) and H(P 1(t-1) - ΔP) are the harmonic powers after adjustment according to + ΔP and - ΔP respectively.

[0091] Step 1103, adjust the power split ratio P 1t = P 1(t-1) - aH’, and collect the current second harmonic power H t ;

[0092] Among them, a is the step coefficient.

[0093] Step 1104, determine whether it satisfies H t-1 - H t < err. If the judgment is yes, end the optimization; if the judgment is no, return to execute step 1102.

[0094] Among them, H t-1 is the harmonic power before adjustment, and H t-1 - Ht ΔP is the power difference, and err is the difference threshold.

[0095] In the embodiments of the present application, when it is detected that the first harmonic power value is greater than the power threshold, the gradient descent method is started to optimize the power division ratio. After determining the adjustment gradient, the adjustable power divider is controlled by the adjustment gradient and the step coefficient to adjust at least two power division ratios, and the second harmonic power after adjustment is detected by the coupler. Then, based on whether the first power difference between the first harmonic power value and the second harmonic power is less than the difference threshold, it is determined whether the optimization process is completed. When the optimization process is not completed, the step of determining the adjustment gradient is continued to be executed to continue the optimization, effectively reducing the harmonic level of the antenna tuner.

[0096] In some embodiments of the present application, after determining the first power difference between the first harmonic power value and the second harmonic power value, the control method further includes: when the first power difference is less than the difference threshold, after a preset time interval, returning to execute the step of receiving the harmonic power signal output by the second path.

[0097] In the embodiments of the present application, when it is detected that the first power difference is less than the difference threshold, it is determined that the optimization of the power division ratio by the adjustable power divider this time has been completed. Since when the user uses the electronic device, there are situations such as different positions of holding the electronic device or the electronic device being close to metal, which cause the harmonic power of the tuner to deteriorate. Therefore, after this optimization is completed, after a preset time interval, the first path and the second path in the coupler are re-controlled to be reversely coupled, and the current harmonic power signal is collected to determine whether it is necessary to start a new round of optimization, realizing real-time monitoring of the harmonic power of at least two antennas. Thus, when the harmonic power is too large, the power division ratios of at least two antennas can be adjusted in time by the adjustable power divider, effectively avoiding the occurrence of excessive harmonic power.

[0098] It should be noted that within the preset time interval, the first path and the second path of the coupler are controlled by the switch to be switched to forward coupling, so that the coupler can collect the forward transmitted power signal when the harmonic power signal is not collected.

[0099] In some embodiments of the present application, determining the adjustment gradient of at least two power division ratios includes: sequentially determining at least two power division ratios as the target power division ratios; adjusting the target power division ratios according to the gradient detection step size, and the other power division ratios except the target power division ratios among the at least two power division ratios change with the adjusted target power division ratios; obtaining at least two third harmonic power values corresponding to the at least two power division ratios, where the at least two third harmonic power values are the power values of the harmonic power signals after adjusting the target power division ratios according to the gradient detection step size; and determining the adjustment gradient according to the at least two third harmonic power values and the first harmonic power value.

[0100] In the embodiments of the present application, when optimizing the power splitting ratios of at least two antennas using the gradient descent algorithm, it is necessary to obtain the adjustment gradient. During the optimization, by setting a small gradient detection step size, the adjustment gradient is obtained by replacing the derivative with a difference. When the number of antennas is greater than two, it is possible to choose to set the gradient detection step sizes for multiple dimensions, and use the difference to replace the partial derivative to determine the adjustment gradient.

[0101] Specifically, during the process of determining the adjustment gradient, it is necessary to poll the power splitting ratios of each antenna, that is, sequentially take each power splitting ratio as the target power splitting ratio. And the target power splitting ratio is adjusted by the preset gradient detection step size. Since the total transmission power of at least two antennas remains unchanged, the other power splitting ratios change with the adjusted target power splitting ratio. During the process of sequentially taking at least two power splitting ratios as the target power splitting ratios and adjusting them according to the gradient detection step size, the harmonic power signals corresponding to each target power splitting ratio are continuously recorded by the coupler, and the corresponding third harmonic power values are determined, that is, the number of third harmonic power values is the same as the number of power splitting ratios. At this time, according to at least two third harmonic power values and the first harmonic power value before adjustment, the adjustment gradient can be calculated.

[0102] Exemplarily, the number of antennas is N, the gradient detection step size is ΔP, and the first harmonic power value is H t , the third harmonic power values are H1, H2 ……, H N . By comparing H t with H1, H2 ……, H N respectively, it is possible to determine the power splitting ratio that has the greatest impact on the harmonic power among at least two power splitting ratios, thereby determining the adjustment gradient.

[0103] In the embodiments of the present application, when the number of antennas and the number of tuners are both at least two, then each power splitting ratio is sequentially taken as the target power splitting ratio and adjusted by the gradient detection step size. According to the at least two third harmonic power values after adjustment and the first harmonic power value before adjustment, the adjustment gradient can be determined, so that the subsequent adjustment of at least two power splitting ratios by this adjustment gradient can effectively reduce the harmonic power of at least two antennas.

[0104] In some embodiments of the present application, determining the adjustment gradient according to at least two third harmonic power values and the first harmonic power value includes: calculating the difference between at least two third harmonic power values and the first harmonic power value respectively to obtain at least two second power differences; calculating the ratio of at least two second power differences to the gradient detection step size respectively to obtain at least two target ratios; determining the adjustment gradient according to at least two target ratios.

[0105] In the embodiments of the present application, at least two third harmonic power values are harmonic powers detected after sequentially adjusting each target power splitting ratio according to a gradient detection step size. By subtracting at least two third series powers from the first harmonic power value respectively, at least two second power differences are obtained. The at least two second power differences can reflect the influence on the harmonic powers of at least two antennas when different power splitting ratios are used as the target power splitting ratio for adjustment. Then, the at least two power differences are calculated with the gradient detection step size, and according to the at least two target ratios obtained from the calculation, the adjustment gradient can be determined.

[0106] Exemplarily, the second power difference is calculated by the following calculation formula (3):

[0107] ΔH N =H t -H N ; (3)

[0108] Wherein, H t is the first harmonic power value, H N is the third harmonic power value, and ΔH N is the second power difference.

[0109] The adjustment gradient is calculated by the following calculation formula (4):

[0110]

[0111] Wherein, ΔH1, ΔH2……, ΔH N are the second power differences, ΔP is the gradient detection step size, and G is the adjustment gradient.

[0112] In the embodiments of the present application, by sequentially polling each power splitting ratio as the target power splitting ratio and obtaining the corresponding at least two second power differences, the adjustment gradient for subsequent adjustment of the power splitting ratio can be determined according to the at least two power differences, further improving the accuracy of subsequent adjustment of at least two power splitting ratios.

Figure 12 The second flowchart of the control method provided in some embodiments of the present application is shown. As Figure 12 shown, the control method includes:

[0114] Step 1201, set the reverse coupling of the coupler through the switch and obtain the first harmonic power value at the current moment;

[0115] Step 1202, determine whether the first harmonic power value is greater than the power threshold. If the determination result is no, execute step 1203; if the determination result is yes, execute step 1204;

[0116] Step 1203: Delay for a preset duration and return to execute Step 1201;

[0117] Step 1204: Fine-tune at least two power splitting ratios by a gradient detection step size and detect the adjustment gradient;

[0118] Step 1205: Adjust at least two power splitting ratios according to the adjustment gradient;

[0119] Step 1206: The coupler detects the second resonant power after adjustment;

[0120] Step 1207: Determine whether the first power difference is less than the difference threshold. If the determination is no, return to execute Step 1204; if the determination is yes, execute Step 1203.

[0121] Wherein, the first power difference is the difference between the second resonant power and the first resonant power.

[0122] In some embodiments of the present application, a control device is provided, which is applied to the electronic device in any of the above embodiments. Figure 13 The schematic block diagram of the control device provided in some embodiments of the present application is shown. As Figure 13 shown, the control device 1300 includes:

[0123] A control module 1302, configured to control the switch to switch the coupling direction of the first path and the second path of the coupler to reverse coupling;

[0125] An adjustment module 1306, configured to control the adjustable power splitter according to the harmonic power signal and adjust the power splitting ratios corresponding to at least two antennas.

[0126] In the embodiments of the present application, a coupler is provided in the antenna assembly, and the coupler can detect the harmonic power. An adjustable power splitter is correspondingly provided, and the adjustable power splitter can adjust the transmission power of each antenna. Therefore, when the controller can control the power splitting ratios of at least two antennas through the adjustable power splitter, it can detect the current harmonic power through the coupler, so as to reallocate the transmission powers of at least two antennas through an optimization algorithm. While keeping the transmission powers of at least two antennas unchanged, the antenna path with relatively poor nonlinearity among at least two antennas undertakes less transmission power, thereby reducing the harmonic components generated by the tuner nonlinearity in the overall antenna assembly and solving the problem of harmonic interference existing in the antenna tuner in the antenna assembly.

After determining the adjustment gradient, the adjustable power divider is controlled by the adjustment gradient and the step coefficient to adjust at least two power division ratios, and the second harmonic power after adjustment is detected by a coupler. Then, based on whether the first power difference between the first harmonic power value and the second harmonic power is less than the difference threshold, it is determined whether the optimization process is completed. When the optimization process is not completed, the step of determining the adjustment gradient is continued to be executed for further optimization, effectively reducing the harmonic level of the antenna tuner.

[0133] In some embodiments of the present application, the execution module is further configured to, when the first power difference is less than the difference threshold, return to execute the step of receiving the harmonic power signal output by the second path after a preset time interval.

[0134] In an embodiment of the present application, when it is detected that the first power difference is less than the difference threshold, it is determined that the optimization of the power division ratio by the adjustable power divider this time has been completed. Since when a user uses an electronic device, there are situations such as different positions of holding the electronic device or the electronic device being close to a metal, resulting in deterioration of the harmonic power of the tuner. Therefore, after this optimization is completed, after a preset time interval, the first path and the second path in the coupler are re-controlled to be reversely coupled to collect the current harmonic power signal, and it is determined whether to start a new round of optimization, realizing real-time monitoring of the harmonic power of at least two antennas, so that when the harmonic power is too large, the power division ratios of at least two antennas can be adjusted in time through the adjustable power divider, effectively avoiding the occurrence of excessive harmonic power.

[0138] An acquisition module, configured to acquire at least two third harmonic power values corresponding to at least two power splitting ratios, where the at least two third harmonic power values are the power values of the harmonic power signals after adjusting the target power splitting ratio according to the gradient detection step size;

[0139] A determination module, configured to determine an adjustment gradient according to the at least two third harmonic power values and the first harmonic power value.

[0140] In the embodiments of the present application, when the number of antennas and the number of tuners are both at least two, each power splitting ratio is sequentially used as the target power splitting ratio, adjusted by the gradient detection step size, and the adjustment gradient can be determined according to the at least two third harmonic power values after adjustment and the first harmonic power value before adjustment, so that the subsequent adjustment of at least two power splitting ratios by the adjustment gradient can effectively reduce the harmonic power of at least two antennas.

[0141] In some embodiments of the present application, the control device 1300 further includes:

[0154] Those skilled in the art can understand that the electronic device 1500 may further include a power source (such as a battery) for supplying power to each component. The power source can be logically connected to the processor 1510 through a power management system, so as to implement functions such as management of charging, discharging, and power consumption management through the power management system. Figure 15 The structure of the electronic device shown in the figure does not limit the electronic device. The electronic device may include more or fewer components than shown in the figure, or combine some components, or have different component arrangements, which will not be elaborated here.

[0155] Among them, the processor 1510 is used to control the switching element to switch the coupling direction of the first path and the second path of the coupler to reverse coupling;

[0156] The processor 1510 is used to receive the harmonic power signal output by the second path;

[0157] The processor 1510 is used to control the adjustable power divider according to the harmonic power signal and adjust the power division ratio corresponding to at least two antennas.

[0158] In the embodiments of the present application, a coupler is provided in the antenna assembly, and the harmonic power can be detected through the coupler, and an adjustable power divider is correspondingly provided. The transmission power of each antenna can be adjusted through the adjustable power divider. Therefore, while the controller can control the power division ratio of at least two antennas through the adjustable power divider, it can detect the current harmonic power through the coupler, so as to reallocate the transmission power of at least two antennas through an optimization algorithm. While keeping the transmission power of at least two antennas unchanged, the antenna path with relatively poor nonlinearity among at least two antennas undertakes less transmission power, thereby reducing the harmonic components generated by the nonlinearity of the antenna tuner in the antenna assembly as a whole, and solving the problem of harmonic interference in the antenna tuner in the antenna assembly.

[0159] Further, the processor 1510 is used to determine the adjustment gradient of at least two power division ratios when the first harmonic power value is greater than the power threshold, where the first harmonic power value is the power value of the harmonic power signal before adjusting the power division ratio;

[0162] A processor 1510 for, when the first power difference is greater than or equal to a difference threshold, returning to execute the step of determining the adjustment gradient of at least two power splitting ratios.

[0163] In an embodiment of the present application, when it is detected that the first harmonic power value is greater than a power threshold, the gradient descent method is started to optimize the power splitting ratio. After determining the adjustment gradient, the adjustable power divider is controlled by the adjustment gradient and the step coefficient to adjust at least two power splitting ratios, and the adjusted second harmonic power is detected by a coupler. Then, based on whether the first power difference between the first harmonic power value and the second harmonic power is less than the difference threshold, it is determined whether the optimization process is completed. When the optimization process is not completed, the step of determining the adjustment gradient is returned to continue the optimization, effectively reducing the harmonic level of the antenna tuner.

[0164] Further, a processor 1510 for, when the first power difference is less than the difference threshold, returning to execute the step of receiving the harmonic power signal output by the second path at intervals of a preset duration.

[0165] In an embodiment of the present application, when it is detected that the first power difference is less than the difference threshold, it is determined that the optimization of the power splitting ratio by the adjustable power divider this time has been completed. Since when a user uses an electronic device, there are situations such as different positions of holding the electronic device or the electronic device being close to a metal, resulting in the deterioration of the harmonic power of the tuner. Therefore, after this optimization is completed, at intervals of a preset duration, the first path and the second path in the coupler are re-controlled to be reversely coupled, the current harmonic power signal is collected, and it is determined whether to start a new round of optimization, realizing real-time monitoring of the harmonic power of at least two antennas, so that when the harmonic power is too large, the power splitting ratios of at least two antennas can be adjusted in time through the adjustable power divider, effectively avoiding the occurrence of the situation where the harmonic power is too large.

[0169] The processor 1510 is configured to determine an adjustment gradient according to the at least two third harmonic power values and the first harmonic power value.

[0170] In an embodiment of the present application, when the number of antennas and the number of tuners are both at least two, each power splitting ratio is sequentially used as a target power splitting ratio and adjusted by a gradient detection step size. According to the at least two third harmonic power values after adjustment and the first harmonic power value before adjustment, the adjustment gradient can be determined, so that the subsequent adjustment of at least two power splitting ratios by the adjustment gradient can effectively reduce the harmonic power of at least two antennas.

[0171] Further, the processor 1510 is configured to calculate differences between the at least two third harmonic power values and the first harmonic power value respectively to obtain at least two second power differences;
