[0021] The technical solutions in the embodiments of the present application will be clearly and completely described in the description of the present application with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

Those skilled in the art can understand the specific meaning of the above terms in the present application according to the specific circumstances. In the present application, the term "A and / or B" includes any one of "A", "B", "A and B". In general, the term "A / B" refers to "A" or "B". In the description of the embodiments of the present application, the terms "first", "second" and the like do not refer to specific, but are used to distinguish the same name objects, and the same name objects referred to by the terms "first", "second" and the like can be the same object under the explicit description of the specification.

[0023] Please refer to Figure 1This is a partial structural schematic diagram of the electronic device 100 in some embodiments of this application. For example... Figure 1 As shown, the electronic device 100 includes at least one antenna 1, at least one detector 2, at least one matching unit 3, and a controller 4. The at least one antenna 1 is used to support the transmission and reception of electromagnetic wave signals in a corresponding frequency band. The at least one detector 2 is configured corresponding to the at least one antenna 1 and is used to detect the operating parameters of the at least one antenna 1. The controller 4 is connected to the at least one detector 2 and the at least one matching unit 3, and is used to receive the operating parameters detected by the at least one detector 2, and, based on the operating parameters detected by the at least one detector, determine that a target conductive object is approaching the electronic device, control the adjustment of the matching parameter value of the at least one matching unit 3 to the matching parameter value corresponding to the scenario where the target conductive object is approaching.

[0024] Therefore, in this application, by detecting the operating parameters of at least one antenna 1 by at least one detector 2, and then determining that a target conductive object is approaching the electronic device 100 based on the operating parameters detected by at least one detector 2, it is possible to effectively and accurately detect / determine that a target conductive object is approaching the electronic device 100. When it is determined that a target conductive object is approaching the electronic device 100, the matching parameter value of at least one matching unit 3 is adjusted to the matching parameter value corresponding to the scenario in which the target conductive object is approaching. This enables the matching unit 3 to achieve better matching in the scenario in which the target conductive object is approaching, thereby improving the antenna performance in the scenario in which the target conductive object is approaching.

[0025] In some embodiments, the controller 4 is used to compare the operating parameters detected by at least one detector 2 with the preset operating parameters corresponding to the target conductive object, and when the operating parameters detected by at least one detector 2 match the corresponding preset operating parameters, it is determined that a target conductive object is approaching the electronic device 100.

[0026] That is, in some embodiments, the electronic device 100 has a preset operating parameter corresponding to the target conductive object for at least one antenna 1, and the controller 4 compares the operating parameter detected by at least one detector 2 with the corresponding preset operating parameter. When the operating parameter detected by at least one detector 2 matches the corresponding preset operating parameter, it is determined that a target conductive object is approaching the electronic device 100.

[0027] The preset working parameter corresponding to the at least one antenna can be obtained by testing the working parameter of the at least one antenna 1 in a scenario where the target conductive object approaches, specifically, the preset working parameter corresponding to each antenna 1 and the target conductive object can be obtained by testing the working parameter of each antenna 1 in a scenario where the target conductive object approaches. For example, a plurality of working parameters of each antenna 1 can be obtained by multiple tests in a scenario where the target conductive object approaches, and the preset working parameter of each antenna 1 can be obtained by averaging the plurality of working parameters of each antenna 1.

[0028] In some embodiments, the preset working parameter corresponding to the target conductive object can also be referred to as the preset working parameter in a scenario where the target conductive object approaches, that is, the preset working parameter corresponding to the scenario where the target conductive object approaches.

[0029] In this application, the matching of the working parameter and the preset working parameter can mean that the working parameter is the same as the preset working parameter or the difference between the working parameter and the preset working parameter is within a preset range, for example, the ratio of the difference between the working parameter and the preset working parameter to the working parameter or the preset working parameter is less than a preset ratio, for example, less than 1 / 5, 1 / 6, 1 / 10, etc.

[0030] In some embodiments, when there is more than one antenna 1, the preset working parameters corresponding to the target conductive object of different antennas 1 can be the same or different. As mentioned above, the preset working parameter corresponding to each antenna 1 and the target conductive object can be obtained by testing the working parameter of each antenna 1 in a scenario where the target conductive object approaches, and because different antennas 1 are located at different positions of the electronic device 100, have the same or different working frequency bands, etc., the corresponding preset working parameters can be the same or different.

[0031] Therefore, when the working parameter detected by the at least one detector 2 matches the corresponding preset working parameter, it indicates that the target conductive object approaches the corresponding antenna 1, and further indicates that the target conductive object approaches the electronic device 100, so that the application determines whether the target conductive object approaches the electronic device 100 by matching the working parameter detected by the at least one detector 2 and the corresponding preset working parameter, which can effectively and accurately determine whether the current is in a scenario where the target conductive object approaches.

[0032] In some embodiments, the number of the at least one antenna 1, the at least one detector 2 and the at least one matching unit 3 is at least two, and the controller 4 is configured to receive the working parameters detected by the at least two detectors 2, compare the working parameters detected by the at least two detectors 2 with the preset working parameters corresponding to the target conductive object, and determine that the target conductive object is close to the electronic device 100 when the working parameters detected by the at least two detectors 2 all match the corresponding preset working parameters.

[0033] In some embodiments, the number of the at least one antenna 1, the at least one detector 2 and the at least one matching unit 3 is at least two, and the controller 4 is configured to receive the working parameters detected by the at least two detectors 2, compare the working parameters detected by the at least two detectors 2 with the preset working parameters corresponding to the target conductive object, and determine that the target conductive object is close to the electronic device 100 when the working parameters detected by the at least two detectors 2 all match the corresponding preset working parameters.

[0034] In some embodiments, the number of the at least one antenna 1, the at least one detector 2 and the at least one matching unit 3 is at least two, and the controller 4 is configured to receive the working parameters detected by the at least two detectors 2, compare the working parameters detected by the at least two detectors 2 with the preset working parameters corresponding to the target conductive object, and determine that the target conductive object is close to the electronic device 100 when the working parameters detected by the at least two detectors 2 all match the corresponding preset working parameters.

[0035] In some embodiments, the number of the at least one antenna 1, the at least one detector 2 and the at least one matching unit 3 is at least two, and the controller 4 is configured to receive the working parameters detected by the at least two detectors 2, compare the working parameters detected by the at least two detectors 2 with the preset working parameters corresponding to the target conductive object, and determine that the target conductive object is close to the electronic device 100 when the working parameters detected by the at least two detectors 2 all match the corresponding preset working parameters.

[0036] In some embodiments, as aforementioned, when there is more than one antenna 1, the preset working parameters corresponding to the target conductive object of different antennas 1 can be the same or different, wherein the controller 4 compares the working parameters detected by each detector 2 with the corresponding preset working parameters, which can be compared with the preset working parameters of the corresponding antenna 1 corresponding to the target conductive object.

[0037] In some embodiments, the controller 4 is configured to periodically acquire the working parameters detected by the at least one detector 2 for a preset number of times, and compare the working parameters detected by the at least one detector 2 acquired each time with the corresponding preset working parameters, and determine that there is a target conductive object close to the electronic device 100 when the ratio of the matching number of times that the working parameters detected by the at least one detector 2 match the corresponding preset working parameters to the preset number of times exceeds a preset ratio.

[0038] That is, in some embodiments, the controller 4 can also periodically acquire the working parameters detected by the at least one detector 2 for multiple times, and compare the working parameters detected by the at least one detector 2 acquired each time with the corresponding preset working parameters, and determine that there is a target conductive object close to the electronic device 100 when the ratio of the matching number of times that the working parameters detected by the at least one detector 2 match the corresponding preset working parameters to the preset number of times exceeds a preset ratio, so as to ensure the accuracy of detection as much as possible and have a certain fault tolerance.

[0039] In some embodiments, the preset ratio can be 70%, 80%, etc., that is, when the working parameters detected are compared with the corresponding preset working parameters for ten times, and the working parameters detected match the corresponding preset working parameters for seven or eight times or more, it is determined that there is a target conductive object close to the electronic device 100.

[0040] In some embodiments, the controller 4 is configured to periodically acquire the working parameters detected by the at least one detector 2 for a preset number of times, which means that the controller 4 periodically acquires the working parameters detected by the at least one detector 2, and acquires the working parameters for a preset number of times in each period. For example, the controller 4 acquires the working parameters detected by the at least one detector 2 periodically with a period of 1 second, and acquires the working parameters detected by the at least one detector 2 for 60 times in the 1 second. Obviously, the period can be any other suitable time length, for example, it can also be 2S, and the preset number of times can also be any other suitable number of times, for example, 30 times, 50 times, 80 times, etc.

[0041] When the number of the at least one antenna 1, the at least one detector 2 and the at least one matching unit 3 are all at least two, i.e., more than one, the controller 4 periodically acquires the working parameters detected by the at least two detectors 2 for a preset number of times, compares the working parameters detected by the at least two detectors 2 acquired each time with the corresponding preset working parameters, and determines that the target conductive object is close to the electronic device 100 when the ratio of the matching number of times that the working parameters detected by the at least two detectors 2 match the corresponding preset working parameters to the preset number of times exceeds a preset ratio.

[0042] Please refer to Figure 2 for a further structural schematic diagram of the electronic device 100 in some embodiments of the present application.

[0043] As Figure 2 shown, in some embodiments, the electronic device further includes a prompting unit 5, and the controller 4 is further configured to acquire the signal quality parameter value of the at least one antenna 1 after adjusting the matching parameter value of the at least one matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object is close, and control the prompting unit 5 to generate a prompting information when the signal quality is lower than a preset signal quality parameter value, the content of the prompting information including at least one of prompting to move away the target conductive object and prompting to adjust the placement posture of the electronic device.

[0044] That is, in some embodiments, after adjusting the matching parameter value of the at least one matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object is close, if the signal quality of the signal quality parameter value of the at least one antenna 1 is still lower than the preset signal quality parameter value, it indicates that adjusting the matching parameter value of the at least one matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object is close cannot solve the problem of poor communication quality, therefore, the controller 4 can control the prompting unit 5 to generate a prompting information, the content of the prompting information including at least one of prompting to move away the target conductive object and prompting to adjust the placement posture of the electronic device, so as to prompt the user to move away the target conductive object or adjust the placement posture of the electronic device so that the beam direction of the at least one antenna 1 can correspond to the optimal beam direction, thereby improving the communication performance.

[0045] The signal quality parameter value can be a parameter value such as an RSRP (Reference Signal Receiving Power) value that reflects the current signal quality. When the RSRP value or other signal quality parameter value is low, it indicates that the current signal is weak and the communication quality is poor. The preset signal quality parameter value can be a critical value reflecting the current weak signal, which can be obtained in advance by testing. When the signal quality parameter value is the RSRP value, the preset signal quality parameter value can also be a preset RSRP value.

[0046] In some embodiments, the controller 4 can obtain the signal quality parameter value from a radio frequency transceiver (not shown in the figure) of the electronic device 100, or can obtain the signal quality parameter value through the power coupler 21.

[0047] In some embodiments, when the detector 2 detects the working parameter of the corresponding antenna 1, the controller 4 can control the adjustment of the matching parameter value of the at least one matching unit 3 to the matching parameter value corresponding to the scenario where the target conductive object is close, by detecting the working parameter of the corresponding antenna 1 in the communication state through the corresponding detector 2, or can control the adjustment of the matching parameter value of the matching unit 3 connected to the antenna 1 currently in the communication state to the matching parameter value corresponding to the scenario where the target conductive object is close, and the controller 4 can obtain the signal quality parameter value of the at least one antenna 1, which can also be the signal quality parameter value of the antenna 1 currently in the communication state.

[0048] In some embodiments, the prompting unit 5 includes at least one of a display screen and a sound output unit, and the prompting information includes at least one of display information and sound information.

[0049] That is, in some embodiments, the prompting unit 5 can include a display screen, such as a touch display screen, or a sound output unit, such as a loudspeaker, or can include both a display screen and a sound output unit. The prompting information accordingly includes display information displayed by the display screen, or sound information output by the sound output unit, or both display information displayed by the display screen and sound information output by the sound output unit. Thus, the user can obtain the prompting information through visual and auditory means, and effective prompting can be achieved.

[0050] In some embodiments, the display information can include any form of display information, such as text, patterns, a combination of text and patterns, or video information.

[0051] In some embodiments, the working parameter of the antenna 1 is a working parameter in the communication process of the antenna 1 receiving and / or transmitting electromagnetic wave signals.

[0052] That is, in some embodiments, as described above, when the detector 2 detects the working parameter of the corresponding antenna 1, the controller 4 can control the adjustment of the matching parameter value of the at least one matching unit 3 to the matching parameter value corresponding to the scenario where the target conductive object is close, by detecting the working parameter of the corresponding antenna 1 in the communication state through the corresponding detector 2, or can control the adjustment of the matching parameter value of the matching unit 3 connected to the antenna 1 currently in the communication state to the matching parameter value corresponding to the scenario where the target conductive object is close, and the controller 4 can obtain the signal quality parameter value of the at least one antenna 1, which can also be the signal quality parameter value of the antenna 1 currently in the communication state.

[0053] Thus, in some embodiments, the working parameter of the antenna 1 is a working parameter in a normal communication process of the antenna 1 for receiving and / or transmitting electromagnetic wave signals, and thus the working parameter of the antenna 1 can be obtained when the antenna 1 is in the normal communication process, so as not to affect the normal working of the antenna 1. Compared with some solutions in which the antenna 1 is switched to a floating state as a proximity sensing induction plate to form a coupling capacitance with a conductive object when the conductive object approaches, the present application does not need to disconnect the antenna 1 from the ground to be in the floating state, so as not to affect the normal working of the antenna 1, and the target conductive object can be effectively detected when the antenna 1 is in the normal communication process.

[0054] In some embodiments, the controller 4 determines at least one final working parameter corresponding to each working parameter detected by each detector 2, and adjusts the matching parameter value of the corresponding matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object approaches the electronic device 100 when the controller 4 determines that the target conductive object approaches the electronic device 100 according to the at least one final working parameter.

[0055] That is, in some embodiments, the controller 4 receives the working parameter detected by each detector 2, determines the final working parameter corresponding to each working parameter detected by each detector 2, and then determines whether the target conductive object approaches the electronic device 100 according to the final working parameter, and adjusts the matching parameter value of the corresponding matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object approaches the electronic device 100 when the controller 4 determines that the target conductive object approaches the electronic device 100 according to the at least one final working parameter.

[0056] In some embodiments, the working parameter detected by each detector 2 includes the incident power and the reflected power of the corresponding antenna 1, the controller 4 obtains the input return loss according to the incident power and the reflected power detected by each detector 2, and adjusts the matching parameter value of the corresponding matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object approaches the electronic device 100 when the controller 4 determines that the target conductive object approaches the electronic device 100 according to the at least one input return loss.

[0057] That is, in some embodiments, the working parameter detected by each detector 2 includes the incident power and the reflected power of the corresponding antenna 1, the controller 4 obtains the final working parameter of the input return loss according to the incident power and the reflected power detected by each detector 2, and then determines whether the target conductive object approaches the electronic device 100 according to the final working parameter of the input return loss.

[0058] The input return loss, also known as reflection coefficient or S11 parameter, represents the impedance matching state of the antenna: when the conductive object approaches, the conductive object tissue absorbs radio frequency energy, causing the antenna load impedance to mismatch, and the input return loss significantly increases, i.e., the input return loss will be large. In addition, the conductive object tissue has a high dielectric constant, which will change the distribution of the electromagnetic field around the antenna when it approaches, causing the antenna impedance to change abruptly, i.e., the input return loss will change greatly. For example, when the conductive object approaches, it will cause impedance mismatch, resulting in deterioration of the input return loss S11 (e.g., from -15 dB to -5 dB), and when the conductive object moves away, the impedance recovers, i.e., the impedance matching is restored, and at this time the input return loss S11 will also be restored to be good (e.g., from -5 dB to -15 dB).

[0059] Therefore, in some embodiments, the controller 4 obtains the input return loss as the final working parameter according to the incident power and the reflected power detected by each detector 2, and then determines whether there is a target conductive object approaching the corresponding antenna 1 according to the input return loss as the final working parameter, so as to determine whether there is a target conductive object approaching the electronic device 100, which can effectively detect whether there is a target conductive object approaching the electronic device 100.

[0060] In some embodiments, the controller 4 obtains the input return loss as the final working parameter according to the incident power and the reflected power detected by each detector 2, which can be obtained by dividing the reflected power detected by each detector 2 by the corresponding incident power. That is, in some embodiments, the input return loss of each antenna can be the ratio between the reflected power and the incident power detected by the corresponding detector 2.

[0061] In some embodiments, the preset working parameter can be a preset input return loss, and after the controller 4 obtains the input return loss as the final working parameter according to the incident power and the reflected power detected by each detector 2, the controller 4 compares the input return loss with the corresponding preset input return loss, and determines that there is a target conductive object approaching the electronic device 100 when the input return loss matches the corresponding preset input return loss.

[0062] Please refer to Figure 3 for another further structural schematic diagram of the electronic device 100 in some embodiments of the present application.

[0063] wherein, Figure 3 a further structure of the electronic device 100 is shown.

[0064] In some embodiments, each detector 2 includes a power coupler 21 arranged in the signal channel T1 of the corresponding antenna 1, and the power coupler 21 is used to detect and obtain the incident power and the reflected power of the corresponding antenna 1.

[0065] That is, in some embodiments, each detector 2 can specifically include a power coupler 21, which is arranged in the signal channel T1 of the corresponding antenna 1, so that the incident power and the reflected power of the corresponding antenna 1 can be detected through the power coupler 21.

[0066] In some embodiments, the power coupler 21 can be a directional coupler.

[0067] Please refer to Figure 4 , the specific schematic diagram of the power coupler in some embodiments of the present application.

[0068] As Figure 4 shown, the power coupler 21 can be a four-port radio frequency device, including an input port 21a, a through port 21b, a first coupling end 21c and a second coupling end 21d.

[0069] Among them, the input port 21a and the through port 21b are in communication, and the input port 21a and the through port 21b are arranged in the signal channel T1 of the corresponding antenna 1, that is, the communication channel between the input port 21a and the through port 21b can be part of the signal channel T1 of the corresponding antenna 1.

[0070] In some embodiments, as Figures 1-4 shown, the electronic device 100 further includes a feed source 6, which is electrically connected with the antenna 1 and used to provide a feed signal for the antenna 1. In some embodiments, the signal channel T1 can be a transmission channel, that is, the channel through which the feed source 6 provides the feed signal for the antenna 1. Among them, the input port 21a is closer to the feed source 6 than the through port 21b, and the feed signal provided by the antenna 1 can be transmitted to the input port 21a, and then transmitted to the through port 21b through the communication channel between the input port 21a and the through port 21b, and then transmitted to the antenna 1 through the through port 21b, so as to excite the antenna 1 to support the transmission and reception of electromagnetic wave signals of the corresponding frequency band.

[0071] Among them, the incident power can be the power of the feed signal, that is, the power of the feed signal transmitted from the input port 21a to the through port 21b. The reflected power can be the power of the signal reflected from the through port 21b back to the input port 21a.

[0072] The first coupling end 21c is used to couple the incident power and output the incident power, and the second coupling end 21d is used to couple the reflected power and output the reflected power. Among them, as Figure 4As shown, the controller 4 can include at least one pair of detection terminals 41, 42, each pair of detection terminals 41, 42 being connected to the first coupling terminal 21c and the second coupling terminal 21d of the corresponding power coupler 21 respectively, and receiving the incident power output by the first coupling terminal 21c and the reflected power output by the second coupling terminal 21d. Wherein, the controller 4 divides the reflected power by the incident power received by each pair of detection terminals 41, 42, and obtains the corresponding input return loss.

[0073] Therefore, in the present application, the input return loss of each antenna 1 can be obtained, and then whether the target conductive object approaches the corresponding antenna 1 is determined according to the input return loss, which is the final working parameter, and whether the target conductive object approaches the electronic device 100 is determined, so that whether the target conductive object approaches the electronic device 100 can be effectively detected.

[0074] Wherein, Figure 4 The specific structure of the power coupler 21 is mainly shown in the figure, and other structures are omitted.

[0075] In some embodiments, the controller 4 can also directly determine whether the target conductive object approaches the corresponding antenna 1 according to the working parameter detected by the at least one detector 2.

[0076] That is, in some embodiments, the controller 4 can directly compare the working parameter detected by a certain detector 2 with the preset working parameter, and when it is determined that the two match, it is determined that the antenna 1 corresponding to the detector 2 has the target conductive object close to it, and then it is determined that the target conductive object approaches the electronic device 100.

[0077] That is, in some embodiments, the working parameter detected by the detector 2 can also be directly used to reflect whether the conductive object approaches the corresponding antenna 1. For example, the working parameter detected by the detector 2 can include the reflected power, and the controller 4 can also directly determine whether the target conductive object approaches the corresponding antenna 1 according to the reflected power detected by the at least one detector 2, and then determine that the target conductive object approaches the electronic device 100. For example, the preset working parameter can also be a preset reflected power, and the controller compares the reflected power detected by the at least one detector 2 with the corresponding preset reflected power, and when it is determined that the reflected power detected by the at least one detector 2 matches the corresponding preset reflected power, it is determined that the target conductive object approaches the electronic device 100.

[0078] In some embodiments, when the at least one antenna 1 and the at least one matching unit 3 include at least two, the matching parameter values corresponding to the scenario that the target conductive object approaches the different matching units 3 can be the same or different.

[0079] In some embodiments, the matching unit 3 can also be configured to have a plurality of matching branches 31, each of which can be enabled or disabled, and the matching unit 3 has different matching parameter values when different matching branches 31 are enabled. The controller 4 can control the preset matching branch to be enabled, so as to adjust the matching parameter value of the matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object is close to the matching unit 3.

[0080] Please refer to Figure 5 , which is a schematic diagram of the structure of the matching unit 3 in some embodiments of the present application.

[0081] As Figure 5 shown, in some embodiments, the matching unit 3 includes a plurality of matching branches 31, each of which can be enabled or disabled. When different matching branches 31 are enabled, the matching unit 3 has different matching parameter values. The controller 4 can control the preset matching branch to be enabled, so as to adjust the matching parameter value of the matching unit 3 to the matching parameter value corresponding to the scenario in which the target conductive object is close to the matching unit 3.

[0082] That is, in some embodiments, different matching branches 31 in the plurality of matching branches 31 have different matching parameter values. Therefore, when different matching branches 31 are enabled, the matching unit 3 as a whole has different matching parameter values, and one of the preset matching branches 31 in the matching unit 3 corresponds to the scenario in which the target conductive object is close to the matching unit 3. Therefore, the matching parameter value of the matching unit 3 can be adjusted to the matching parameter value corresponding to the scenario in which the target conductive object is close to the matching unit 3 by controlling the preset matching branch 31 to be enabled.

[0083] Further, the preset matching branch 31 can be pre-configured. When the preset matching branch 31 is enabled, the matching parameter value of the matching unit 3 can be adjusted to the matching parameter value corresponding to the scenario in which the target conductive object is close to the matching unit 3.

[0084] In some embodiments, when the preset matching branch 31 is enabled, the other matching branches 31 are disabled.

[0085] In some embodiments, when a certain matching branch 31 is in the enabled state, it means that the matching branch 31 can play a role in impedance matching and other matching tuning. When a certain matching branch 31 is in the disabled state, it means that the matching branch 31 does not work, i.e., it cannot play a role in matching tuning.

[0086] In some embodiments, the plurality of matching branches 31 can be connected in parallel between the feed source 6 and the corresponding antenna 1, and / or can also be connected in parallel between the antenna 1 and the ground GND.

[0087] In some embodiments, as Figure 5 shown, the plurality of matching branches 31 includes a plurality of matching branches 31 connected in parallel between the corresponding antenna 1 and the ground, for example, as Figure 5The two matching branches 31 are shown, one of which is a preset matching branch 31.

[0088] wherein, Figure 5 In some embodiments, the matching unit 3 is shown to include a plurality of matching branches 31, each of which is connected in parallel between the corresponding antenna 1 and the ground GND.

[0089] In some embodiments, the matching unit 3 is shown to include a plurality of matching branches 31, each of which is connected in parallel between the corresponding antenna 1 and the ground GND. Figure 5 The matching unit 3 is shown to further include a switch module 32 connected between the plurality of matching branches 31 and the antenna 1, or connected between the plurality of matching branches 31 and the ground GND, and the plurality of matching branches 31 are connected in parallel between the switch module 32 and the ground GND, or connected in parallel between the antenna 1 and the switch module 32. The switch module 32 is configured to, under the control of the controller 4, turn on the electrical connection between the corresponding matching branch 31 and the antenna 1 and the ground GND, so that the corresponding matching branch 31 is in an enabled state. When the switch module 32 turns on the electrical connection between the preset matching branch 31 and the antenna 1 and the ground GND under the control of the controller 4, so that the preset matching branch 31 is in an enabled state, the matching parameter value of the matching unit is the matching parameter value corresponding to the scenario close to the target conductive object.

[0090] In some embodiments, the controller 4 is connected to the switch module 32 of the matching unit 3, and controls the corresponding switch module 32 as needed, so that the switch module 32 can turn on the electrical connection between the corresponding matching branch 31 and the antenna 1 and the ground GND under the control of the controller 4, so that the corresponding matching branch 31 is in an enabled state, so that the matching parameter value of the matching branch 31 meets the impedance matching requirement of the receiving frequency band.

[0091] wherein, Figure 5 In some embodiments, the matching unit 3 is shown to include a plurality of matching branches 31, each of which is connected in parallel between the corresponding antenna 1 and the ground GND.

[0092] In some embodiments, the matching unit 3 is shown to include a plurality of matching branches 31, each of which is connected in parallel between the corresponding antenna 1 and the ground GND. Figure 5 Each matching branch 31 includes a matching element M1, and the matching element M1 includes a capacitor and / or an inductor. The matching parameter value of each matching branch 31 can be the matching parameter value presented by at least one matching element M1.

[0093] wherein, in some embodiments, as shown in Figure 5As shown, the plurality of matching branches 31 is two, and the switch module 32 includes a single-pole double-throw switch SW1, and the single-pole double-throw switch SW1 is used to selectively establish that the matching element M1 in one of the matching branches 31 is electrically connected between the antenna 1 and the ground. Among them, the single-pole double-throw switch SW1 can include a fixed end and a throw end, when the switch module 32 is connected between the plurality of matching branches 31 and the antenna 1, the fixed end is fixedly connected with the antenna 1, and the throw end can be selectively connected with one end of the matching element M1 in one of the matching branches 31, and the other end of the matching element M1 is grounded. When the single-pole double-throw switch SW1 establishes the connection between the antenna 1 and one end of the matching element M1 in one of the matching branches 31, the matching element M1 in one of the matching branches 31 is electrically connected between the antenna 1 and the ground. Among them, when the switch module 32 is connected between the plurality of matching branches 31 and the ground GND, and the plurality of matching branches 31 are connected in parallel between the antenna 1 and the switch module 32, one end of the matching element M1 in the plurality of matching branches 31 is connected with the antenna 1, and the fixed end of the single-pole double-throw switch included in the switch module 32 can be connected with the ground GND, and the throw end can be selectively connected with the other end of the matching element M1 in one of the matching branches 31.

[0094] In some embodiments, the switch module 32 can also include a plurality of matching switches, and the plurality of matching switches correspond one-to-one to the plurality of matching branches 31, and each matching switch is connected in series with the matching element M1 of the corresponding matching branch 31. In some embodiments, the matching branch in the enabled state can be switched according to the switching of the on and off states of the matching switch.

[0095] Among them, as shown in Figure 5 The matching unit 3 also includes a first inductor L1, a first capacitor C1, and a second inductor L2, the first inductor L1 and the first capacitor C1 are connected in series between the antenna 1 and the at least two matching branches 31, one end of the second inductor L2 is connected with the end of the first capacitor C1 away from the first inductor L1, and the other end is grounded.

[0096] That is, in some embodiments, the matching unit 3 also includes a first inductor L1, a first capacitor C1, and a second inductor L2, and when the preset matching branch 31 is enabled, the first inductor L1, the first capacitor C1, and the second inductor L2 cooperate to make the matching parameter value of the matching unit 3 ultimately correspond to the matching parameter value of the scenario close to the target conductive object. By adding the first inductor L1, the first capacitor C1, and the second inductor L2, the accuracy of adjustment can be improved.

[0097] Among them, as in the foregoing, Figure 5 embodiments, as shown in Figure 5 The two matching branches 31 respectively include a capacitor C2 and an inductor L3.

[0098] In other embodiments, any of the matching branches 31 can also include a series structure or a parallel structure of inductance and capacitance, or further include a plurality of series-connected capacitances and / or inductances, or include a plurality of parallel-connected capacitances and / or inductances, or further include a structure of parallel connection of a capacitance and an inductance and then series connection of the capacitance, and the like.

[0099] In some embodiments, the controller 4 can also be configured to determine, according to the working parameter detected by the at least one detector 2, that there is no target conductive object approaching the electronic device 100, and control the matching parameter value of the at least one matching unit 3 to be adjusted to a matching parameter value corresponding to a scenario in which the target conductive object is not approaching.

[0100] That is, in some embodiments, when there is no target conductive object approaching the electronic device 100, the controller 4 can also adjust the matching parameter value of the at least one matching unit 3 to a matching parameter value corresponding to a scenario in which the target conductive object is not approaching, so as to improve the communication performance in the scenario in which the target conductive object is not approaching.

[0101] In some embodiments, Figure 6 In some embodiments, the matching unit 3 includes two matching branches 31, one of which is a matching branch 31 corresponding to a scenario in which the target conductive object is approaching, and the other is a matching branch 31 corresponding to a scenario in which the target conductive object is not approaching. Thus, the controller 4 can control the corresponding matching branch 31 to be enabled according to the current scenario, so that the matching parameter value of the matching unit 3 is the matching parameter value corresponding to the current scenario, thereby facilitating the improvement of the communication performance in the current scenario.

[0102] In some embodiments, the controller 4 can also compare the working parameter detected by the at least one detector 2 with a preset working parameter corresponding to a scenario in which there is no target conductive object approaching, and determine that there is no target conductive object approaching when the working parameter detected by the at least one detector 2 is determined to be the preset working parameter corresponding to the scenario in which there is no target conductive object approaching. Details of the comparison between the working parameter detected by the at least one detector 2 and the preset working parameter corresponding to a scenario in which there is a target conductive object approaching are similar to the foregoing, and will not be described here.

[0103] In some embodiments, the controller 4 is further configured to, when it is determined that there is a target conductive object approaching the electronic device 100, further acquire the current time and generate a corresponding time stamp to record the time at which the target conductive object approaches the electronic device 100.

[0104] That is, in some embodiments, the controller 4 can further acquire the current time when it is determined that the target conductive object approaches the electronic device 100, and generate a corresponding time stamp, which records the time when the target conductive object approaches the electronic device 100, so as to determine the user's behavior habits later, for example, record the time period when the user uses the target conductive object every day, so that the controller 4 can further control according to the user's behavior habits later, improve the intelligence, and also meet the personalized needs of the user.

[0105] In some embodiments, the time stamp can include event and time information, so as to record the time when the event occurs.

[0106] Please refer to Figure 6 , which is a further structure schematic diagram of the electronic device 100 in some embodiments of the present application.

[0107] As Figure 6 shown, the electronic device 100 further includes a memory 7, wherein the controller 4 can control to store the time stamp in the memory 7.

[0108] Among them, Figure 1 in order to further illustrate the memory 7 on the basis of Figure 7 , the other structures of the electronic device 100 can also be the structures in any of the foregoing embodiments.

[0109] In some embodiments, the controller 4 can periodically acquire the working parameters detected by the at least one detector 2 for a preset number of times, and also store the working parameters detected by the at least one detector 2 and the matching results with the corresponding preset working parameters in the memory 7 each time in a period, and after the period ends, count the matching times of the working parameters detected by the at least one detector 2 and the corresponding preset working parameters, and when the ratio of the matching times of the working parameters detected by the at least one detector 2 and the corresponding preset working parameters to the preset number of times exceeds a preset ratio, it can be determined that the target conductive object approaches the electronic device 100.

[0110] Please refer to Figure 7 , which is a further structure schematic diagram of the electronic device 100 in some embodiments of the present application.

[0111] Among them, Figure 3 mainly illustrates the specific structure of the controller 4.

[0112] Among them, in some embodiments, as shown in the foregoing Figure 7 , each detector 2 includes a power coupler 21, which is arranged in the signal channel T1 of the corresponding antenna 1, and the power coupler 21 is used to detect and acquire the incident power and the reflected power of the corresponding antenna 1.

[0113] As shown in Figure 7 In some embodiments, the controller 4 can include a detection module 4a, an analog-to-digital conversion module 4b, and a processing module 4c, wherein the detection module 4a can be coupled with at least one power coupler 21 to receive the incident power and the reflected power of the corresponding antenna 1 obtained by the at least one power coupler 21, the analog-to-digital conversion module 4b is connected between the detection module 4a, the analog-to-digital conversion module 4b, and the processing module 4c, for converting the incident power and the reflected power received by the detection module 4a into corresponding numerical values, i.e., obtaining corresponding incident power values and reflected power values, and inputting them to the processing module 4c, and the processing module 4c is used to receive the corresponding incident power values and reflected power values, and calculate the corresponding input return loss according to the incident power values and the reflected power values.

[0114] In some embodiments, the detection module 4a can include at least two detection ports Dt1, and be connected with at least one power coupler 21 through the at least two detection ports Dt1 to receive the incident power and the reflected power of the corresponding antenna 1 obtained by the corresponding power coupler 21, i.e., the detection module 4a can include at least one pair of detection ports Dt1, and each pair of detection ports Dt1 is connected with one power coupler 21. Wherein, one pair of detection ports Dt1 of the detection module 4a can be connected with the detection ends 41, 42 of the controller 4, or can be equivalent to the detection ends 41, 42 of the controller 4.

[0115] Wherein, the controller 4 can be a radio frequency dedicated chip, i.e., a related chip for radio frequency processing, which can also be called a radio frequency enhanced chip. By increasing the radio frequency dedicated chip, the radio frequency processing and control functions required can be realized in cooperation with the original radio frequency transceiver in the radio frequency module of the electronic device 100. Wherein, the detection module 4a, the analog-to-digital conversion module 4b, and the processing module 4c can be circuits or chips integrated in the radio frequency dedicated chip.

[0116] Wherein, in some embodiments, the controller 4 can also be a central processing unit, a microcontroller, a single-chip microcomputer, a digital signal processor, etc.

[0117] In some embodiments, the functions performed by the aforementioned controller 4 can mainly be performed by the processing module 4c. The matching unit 3 can be connected with the processing module 4c and adjust its matching parameter value under the control of the processing module 4c.

[0118] Wherein, Figure 3 On the basis of the electronic device 100 shown in Figure 8 The specific structure of the controller 4 is further shown on the basis of the electronic device 100, and the other structures of the electronic device 100 can be the structures in any of the aforementioned embodiments.

[0119] In the present application, the at least one frequency band supported by the at least one antenna 1 can be at least one of, for example, a GPS frequency band, a low frequency band, a medium-high frequency band, a 5G NR frequency band, a WiFi frequency band, a satellite communication frequency band, and the like.

[0120] In the foregoing, when the detector 2 detects the working parameter of the corresponding antenna 1, the controller 4 can control the matching parameter value of the at least one matching unit 3 to be adjusted to the matching parameter value corresponding to the scenario where the target conductive object is close, which can also be that the controller 4 controls the matching parameter value of the matching unit 3 connected to the antenna 1 currently in the communication state to be adjusted to the matching parameter value corresponding to the scenario where the target conductive object is close, and the controller 4 can obtain the signal quality parameter value of the at least one antenna 1, which can also be that the controller 4 obtains the signal quality parameter value of the antenna 1 currently in the communication state. In the foregoing, the frequency band supported by the antenna 1 currently in the communication state can also be at least one of, for example, a GPS frequency band, a low frequency band, a medium-high frequency band, a 5G NR frequency band, a WiFi frequency band, a satellite communication frequency band, and the like.

[0121] In some embodiments, the target conductive object is a protective case for being sleeved on the electronic device 100, and at least a partial region of the protective case is made of a metal material.

[0122] That is, in some embodiments, the target conductive object is a protective case made of a metal material in a partial region or an entire region. At present, many protective cases are made of a metal material in an entire region or a partial region to improve user experience due to the better appearance and hand feeling of the protective case made of a metal material. However, when the protective case is sleeved on the electronic device 100, the antenna performance of the antenna 1 of the electronic device 100 is affected due to the fact that at least a partial region of the protective case is made of a metal material. In the present application, when it is determined that the target conductive object is close to the electronic device 100, the matching parameter value of the at least one matching unit 3 is adjusted to the matching parameter value corresponding to the scenario where the target conductive object is close, which can ensure the antenna performance while allowing the protective case made of a metal material in at least a partial region to be used.

[0123] In some embodiments, the target conductive object can also be a human hand or other conductive objects.

[0124] Please refer to Figure 8 The present application is a comparison schematic diagram of the return loss of the electronic device and the reference electronic device when sleeved with the protective case.

[0125] In the foregoing, Figure 8The return loss curve S11-1 obtained by simulation test when the electronic device 100 of the present application works in a certain frequency band with a protective shell made at least partially of metal material is shown in the figure, and the return loss curve S11-2 obtained by simulation test when the reference electronic device works in a certain frequency band with a protective shell made at least partially of metal material is shown in the figure. Among them, the electronic device 100 of the present application adjusts the matching parameter value of the corresponding matching unit to the matching parameter value corresponding to the scenario where the target conductive object is close when the protective shell is sleeved, and the reference electronic device is an electronic device without this function, that is, the original matching parameter value is kept.

[0126] Among them, Figure 8 In the figure, the GPS L1 frequency band (the resonant frequency is about 1.6 GHz) is taken as an example for illustration.

[0127] As Figure 9 shown, the return loss of the reference electronic device is about -0.36 dB in the GPS L1 frequency band when sleeved with a protective shell made at least partially of metal material, and the loss is high. The return loss of the electronic device 100 of the present application is greater than only -7.96 dB when sleeved with a protective shell made at least partially of metal material, and the return loss is obviously reduced, because the matching parameter value of the corresponding matching unit is adjusted to the matching parameter value corresponding to the scenario where the target conductive object is close.

[0128] As can be seen, the electronic device 100 in the present application can reduce the loss and ensure the antenna performance when the target conductive object is close to the electronic device 100 by adjusting the matching parameter value of the corresponding matching unit 3 to the matching parameter value corresponding to the scenario where the target conductive object is close, on the premise of allowing to use a protective shell made at least partially of metal material.

[0129] Please refer to Figure 9 , for the impedance matching comparison between the electronic device and the reference electronic device in some embodiments of the present application when sleeved with a protective shell.

[0130] Among them, Figure 9 The impedance matching position P11 when the electronic device 100 of the present application works in a certain frequency band with a protective shell made at least partially of metal material is shown in the figure, and the impedance matching position P12 when the reference electronic device works in a certain frequency band with a protective shell made at least partially of metal material is shown in the figure. Among them, the electronic device 100 of the present application adjusts the matching parameter value of the corresponding matching unit to the matching parameter value corresponding to the scenario where the target conductive object is close when the protective shell is sleeved, and the reference electronic device is an electronic device without this function, that is, the original matching parameter value is kept.

[0131] Its Figure 9As shown, the reference electronic device has an impedance matching position P12 when the protective case made at least partially of metal material is set on the electronic device in the frequency band. The electronic device 100 of the present application has an impedance matching position P11 when the protective case made at least partially of metal material is set on the electronic device, and the impedance matching position is closer to the center of the Smith chart. Figure 10 As shown, the center position of the Smith chart indicates that the impedance matching is better at this time, so that better impedance matching of the scenario close to the target conductive object can be achieved.

[0132] Please refer to Figure 10 , which is a schematic diagram of the antenna efficiency comparison between the electronic device of some embodiments of the present application and the reference electronic device when the protective case is set.

[0133] Among them, Figure 10 In the above-mentioned figures, the antenna efficiency is shown in the total system efficiency. Among them, Figure 10 In the above-mentioned figures, the system total efficiency curve St1 obtained by simulation test when the electronic device 100 of the present application works in a certain frequency band when the protective case made at least partially of metal material is set on the electronic device, and the return loss curve St2 obtained by simulation test when the reference electronic device works in a certain frequency band when the protective case made at least partially of metal material is set on the electronic device. Among them, the electronic device 100 of the present application adjusts the matching parameter value of the corresponding matching unit to the matching parameter value corresponding to the scenario close to the target conductive object when the protective case is set, and the reference electronic device is an electronic device without this function, i.e. keeping the original matching parameter value.

[0134] Among them, Figure 10 In the above-mentioned figures, the GPS L1 frequency band (resonant frequency about 1.6 GHz) is taken as an example for illustration.

[0135] As shown in the above-mentioned figures, Figure 1 As shown, the reference electronic device has a system total efficiency of about -23 dB in the GPS L1 frequency band when the protective case made at least partially of metal material is set on the electronic device, and the efficiency is low. The electronic device 100 of the present application has a system total efficiency of more than -14 dB when the protective case made at least partially of metal material is set on the electronic device, and the system total efficiency is obviously improved, because the matching parameter value of the corresponding matching unit is adjusted to the matching parameter value corresponding to the scenario close to the target conductive object.

[0136] As can be seen, when the target conductive object is close to the electronic device 100, the electronic device 100 of the present application can improve the efficiency and ensure the antenna performance by adjusting the matching parameter value of the corresponding matching unit 3 to the matching parameter value corresponding to the scenario close to the target conductive object, under the premise of allowing the use of the protective case made at least partially of metal material.

[0137] wherein, Figure 11 As shown in FIGS. 1-3, at least one antenna 1 is taken as an example of two. The at least one antenna 1 can be all antennas of the electronic device 100 arranged at or near the frame position of the electronic device 100.

[0138] For example, in some embodiments, the frame of the electronic device 100 is a metal frame, and the at least one antenna 1 is a metal frame segment formed by opening a gap in the metal frame of the electronic device 100.

[0139] For another example, in some embodiments, the frame of the electronic device 100 is a non-metal frame, and the first radiation branch 11 and the like are metal segments arranged in the frame of the electronic device 100.

[0140] That is, in other embodiments, the frame of the electronic device 100 can also be a frame with low conductivity made of plastic, plastic, ceramic, or the like. The at least one antenna 1 is a metal segment arranged in the frame of the electronic device 100. The at least one antenna 1 can be embedded in the frame of the electronic device 100 or arranged on the inner side surface of the frame of the electronic device 100.

[0141] In some embodiments, the electronic device 100 can further include an antenna support made of an insulating material. The at least one antenna 1 and the like can be fixed on the corresponding antenna support and fixed on the corresponding position of the electronic device 100 through the antenna support. For example, fixed on the corresponding position near the frame of the electronic device 100 through the antenna support.

[0142] In some embodiments, the first radiation branch and the like can be an FPC (flexible printed circuit) fixedly arranged on the antenna support or an LDS (Laser-Direct-structuring) metal segment formed on the antenna support through laser technology, or a PDS (Printing Direct Structure) metal segment formed on the antenna support through PDS technology (for example, a metal segment formed by printing conductive ink, conductive silver paste, or the like on the antenna support), and fixed on the corresponding position in the electronic device 100, for example, the corresponding position near the frame, through the antenna support.

[0143] Please refer to Figure 11 , which is a structural block diagram of the electronic device assembly 200 in some embodiments of the present application.

[0144] As shown in FIG. 4, the electronic device assembly 200 includes a first antenna 1 and a second antenna 2. Figure 12As shown, the electronic device 200 comprises the electronic device 100 of any of the preceding embodiments, and further comprises a protective shell 201, wherein the protective shell 201 is configured to be sleeved on the electronic device 100, and at least a partial region of the protective shell 201 is made of a metal material.

[0145] That is, the protective shell 201 can be a protective shell made of a metal material in a partial region or an entire region, and the appearance and the feel of the protective shell made of the metal material are better, and thus the user experience can be improved. In addition, in the present application, when the protective shell 201 is sleeved on the electronic device 200, that is, when it is determined that the target conductive object is close to the electronic device 100, the matching parameter value of the at least one matching unit 3 is adjusted to the matching parameter value corresponding to the scenario in which the target conductive object, that is, the protective shell 201, is close, and thus the antenna performance is ensured while allowing the use of the protective shell made of the metal material in the partial region.

[0146] In the present application, the electronic device 100 can be any electronic device such as a mobile phone, a tablet computer, a digital camera, a notebook computer, etc.

[0147] In the present application, the controller 4 can be a central controller, a communication processing chip, a digital signal processor, a single-chip microcomputer, etc. As mentioned above, the controller 4 can be a separate processing chip, or can be integrated in the radio frequency transceiver.

[0148] In some embodiments, the memory 7 can be any form of memory such as an optical disc, a hard disk, a U disk, a flash memory card, etc.

[0149] Please refer to Figure 13 is a flowchart of a communication control method in an embodiment of the present application. In some embodiments, the communication control method is applied to an electronic device, and the electronic device comprises at least one antenna, at least one detector, and at least one matching unit, the at least one detector is respectively arranged corresponding to the at least one antenna, the at least one matching unit is respectively connected to the at least one antenna, and the matching parameter value of each matching unit is adjustable. In the present application, the electronic device can be the electronic device 100 of any of the preceding embodiments. Obviously, the communication control method can also be applied to other electronic devices. The communication control method comprises the following steps: 121: detecting the working parameters of the at least one antenna by the at least one detector, respectively; and 123: when it is determined that the target conductive object is close to the electronic device according to the working parameters detected by the at least one detector, adjusting the matching parameter value of the at least one matching unit to the matching parameter value corresponding to the scenario in which the target conductive object is close.

[0150] Thus, the communication control method of the present application can effectively and accurately detect / determine the approach of the target conductive object to the electronic device by detecting the working parameters of the at least one antenna by the at least one detector and then determining the approach of the target conductive object to the electronic device according to the working parameters detected by the at least one detector, and can control the adjustment of the matching parameter values of the at least one matching unit to the matching parameter values corresponding to the scenario in which the target conductive object approaches when it is determined that the target conductive object approaches the electronic device, so that the matching unit can achieve better matching in the scenario in which the target conductive object approaches, and the performance of the antenna in the scenario in which the target conductive object approaches can be improved.
