Description

Electronic equipment and antenna power control methods

[0001] This application claims priority to the invention patent application filed on May 25, 2024, with application number "2024106595921" and title "Electronic Device and Antenna Power Control Method". Technical Field

[0002] This application relates to the field of communication technology, and in particular to an electronic device and an antenna power control method. Background Technology

[0003] Currently, with the widespread adoption of 5G communication technology, people's communication experience is improving significantly. Antenna transmission power is directly proportional to antenna radiation performance. In scenarios with poor antenna radiation performance, current methods often improve it by increasing transmission power. However, if the antenna transmission power is set too high, the SAR (Specific Absorption Rate) value will exceed the standard, failing to meet safety regulations. Therefore, ensuring both antenna radiation performance and SAR compliance has become a problem that needs to be solved. Summary of the Invention

[0004] This application provides an electronic device and an antenna power control method that can effectively increase antenna power while meeting SAR value compliance and improving user experience while ensuring radiation safety.

[0005] In a first aspect, an electronic device is provided, comprising a radio frequency (RF) unit, a controller, and at least one antenna. The RF unit is selectively connected to the at least one antenna for receiving and / or transmitting electromagnetic wave signals in a preset frequency band via at least one target antenna. The controller is configured to acquire a first signal quality parameter when the at least one target antenna is receiving and / or transmitting electromagnetic wave signals, and, when the first signal quality parameter indicates that the current signal quality is lower than a first preset signal quality, control the execution of a first power adjustment operation, wherein the first power adjustment operation includes: a first adjustment process: increasing the transmission power of the RF unit by a first preset power adjustment value at first preset time intervals until a first preset condition is met; and a second adjustment process: when the first preset condition is met, decreasing the transmission power of the RF unit by a second preset power adjustment value at second preset time intervals until the first signal quality parameter indicates that the current signal quality is again lower than the first preset signal quality, at which point the execution of the first adjustment process is returned.

[0006] Secondly, an antenna power control method is also provided, applied in an electronic device, the electronic device including a radio frequency unit and at least one antenna, the radio frequency unit being connected to the at least one antenna for receiving and / or transmitting electromagnetic wave signals in a preset frequency band through at least one target antenna among the at least one antenna. The antenna power control method includes: acquiring a first signal quality parameter when the at least one target antenna is receiving and / or transmitting electromagnetic wave signals; and when it is determined that the first signal quality parameter reflects a current signal quality lower than a first preset signal quality, controlling the execution of a first power adjustment operation, wherein the first power adjustment operation includes: a first adjustment process: increasing the transmission power of the radio frequency unit by a first preset power adjustment value every first preset time interval until a first preset condition is met; and a second adjustment process: when the first preset condition is currently met, decreasing the transmission power of the radio frequency unit by a second preset power adjustment value every second preset time interval until it is determined that the first signal quality parameter reflects a current signal quality lower than the first preset signal quality again, then returning to the execution of the first adjustment process.

[0007] The antenna power control method and electronic device of this application, when the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, controls the execution of a first power adjustment operation including a first adjustment process and a second adjustment process. In the first adjustment process, the signal quality is improved by gradually increasing the transmission power to enhance the antenna radiation performance, thus avoiding a sudden increase in transmission power that could lead to SAR values ​​exceeding the limit. When the first preset condition is met, the transmission power of the radio frequency unit is reduced by a second preset power adjustment value at second preset time intervals, which also avoids SAR values ​​exceeding the limit while preventing excessive reduction in signal quality. Furthermore, when the first signal quality parameter reflects that the current signal quality is lower than the preset signal quality, this application returns to executing the first adjustment process. Therefore, by cyclically executing the first and second adjustment processes, the overall signal quality can be effectively improved, and SAR values ​​exceeding the limit can be avoided.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] In the description of this application, unless otherwise expressly specified and limited, the term "connection" should be interpreted broadly. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, an indirect connection through an intermediate medium, or a connection within two components; it can be a communication connection; or it can be an electrical connection. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances. In this application, the term "A and / or B" includes any one of "A", "B", or "A and B". The term "A / B" generally refers to either "A" or "B". In the description of the embodiments of this invention, the terms "first", "second", etc., are not specific, but are used to distinguish objects with the same name. Where specified in the specification, the objects with the same name referred to by the terms "first", "second", etc., can be the same objects.

[0028] Please refer to Figure 1, which is a partial structural schematic diagram of an electronic device 100 in some embodiments of this application. As shown in Figure 1, the electronic device 100 includes at least one antenna 1, a radio frequency unit 2, and a controller 3. The radio frequency unit 2 is selectively connected to the at least one antenna 1, and is used to receive and / or transmit electromagnetic wave signals in a preset frequency band through at least one target antenna among the at least one antenna 1. The controller 3 is used to acquire a first signal quality parameter when the at least one target antenna receives and / or transmits electromagnetic wave signals, and when the first signal quality parameter reflects that the current signal quality is lower than a first preset signal quality, control the execution of a first power adjustment operation, wherein the first power adjustment operation includes: a first adjustment process: increasing the transmission power of the radio frequency unit by a first preset power adjustment value at first preset time intervals until a first preset condition is met; and a second adjustment process: when the first preset condition is met, decreasing the transmission power of the radio frequency unit by a second preset power adjustment value at second preset time intervals until the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, and then returning to execute the first adjustment process.

[0029] Therefore, in this application, when the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, a first power adjustment operation, including a first adjustment process and a second adjustment process, is executed. During the first adjustment process, the signal quality is improved by gradually increasing the transmission power to enhance the antenna radiation performance. This avoids a sudden increase in transmission power that could lead to SAR values ​​exceeding the limit. Furthermore, when the first preset condition is met, the transmission power of the radio frequency unit 2 is reduced by a second preset power adjustment value at second preset time intervals. This also avoids both SAR values ​​exceeding the limit and excessively degrading the signal quality. Moreover, when the first signal quality parameter reflects that the current signal quality is lower than the preset signal quality, this application returns to executing the first adjustment process. Thus, by cyclically executing the first and second adjustment processes, the overall signal quality can be effectively improved, and SAR values ​​exceeding the limit can be avoided.

[0030] In some embodiments, the first preset condition includes the transmission power reaching a preset power upper limit or the first signal quality parameter reflecting the current signal quality being higher than or equal to a second preset signal quality, wherein the second preset signal quality is higher than the first preset signal quality.

[0031] That is, in some embodiments, during the first adjustment process, the transmission power of the radio frequency unit 2 is increased by a first preset power adjustment value at a first preset time interval until a first preset condition is met, that is, until the transmission power reaches a preset power upper limit value or the first signal quality parameter reflects the current signal quality or is equal to or higher than a second preset signal quality, indicating that the transmission power is high at this time. Therefore, the second adjustment process is executed at this time, that is, the transmission power of the radio frequency unit 2 is decreased by a second preset power adjustment value at a second preset time interval to gradually reduce the transmission power and avoid the SAR value from exceeding the standard, until the first signal quality parameter reflects the current signal quality as being lower than the first preset signal quality, then the first adjustment process is executed again, and the transmission power is gradually increased again. In this way, the overall signal quality can be effectively improved and the SAR value can be avoided from exceeding the standard.

[0032] The preset power upper limit value can be the maximum transmission power that the radio frequency unit 2 can achieve, or it can be slightly less than the maximum transmission power that the radio frequency unit 2 can achieve.

[0033] The first preset time and the second preset time may be the same or different, and the first preset power adjustment value and the second preset power adjustment value may also be the same or different.

[0034] In some embodiments, the controller 3 only controls the execution of the second adjustment process when the first preset condition is currently met and the duration of meeting the first preset condition reaches a preset duration. This further improves signal quality. The preset duration is related to at least one target antenna currently receiving and / or transmitting electromagnetic wave signals. For example, it is related to the position of the at least one target antenna within the electronic device 100. For instance, when the position of the at least one target antenna within the electronic device 100 is unlikely to cause SAR values ​​to exceed the limit (e.g., when the at least one target antenna is located at the back of the electronic device 100), the preset duration can be longer. Conversely, when the position of the at least one target antenna within the electronic device 100 is likely to cause SAR values ​​to exceed the limit, the preset duration can be shorter, or even close to zero.

[0035] In some embodiments, the first signal quality parameter includes bit error rate and / or Received Signal Strength Indication (RSSI). When the bit error rate is greater than or equal to a first preset bit error rate, and / or the received signal strength indicated by the received signal strength indicator is lower than the first preset signal strength, the controller 3 determines that the current signal quality is lower than the first preset signal quality. When the bit error rate is less than or equal to a second preset bit error rate, and / or the received signal strength indicated by the received signal strength indicator is higher than or equal to the second preset signal strength, the controller 3 determines that the current signal quality is higher than or equal to the second preset signal quality. The second preset signal strength is higher than the first preset signal strength, and the second preset bit error rate is lower than the second preset bit error rate.

[0036] In this application, the aforementioned power adjustment operation mainly adjusts the transmission power, that is, it adjusts the power of the radio frequency unit 2 during the transmission of electromagnetic wave signals in a preset frequency band through at least one target antenna of the at least one antenna 1. In some embodiments, the first signal quality parameter includes bit error rate and / or received signal strength indication. Since a higher bit error rate indicates a worse signal quality during transmission, and a higher received signal strength indication indicates a better signal quality during transmission, and the received signal strength indication is usually positively correlated with the signal quality during transmission, a higher received signal strength indication also indicates a better signal quality during transmission. Therefore, in this application, when the bit error rate is greater than or equal to a first preset bit error rate, and / or the received signal strength indicated by the received signal strength indicator is lower than the first preset signal strength, it indicates that the current signal quality is lower than the first preset signal quality. At this time, the controller 3 controls the execution of a first adjustment process, gradually increasing the transmission power. Conversely, when the bit error rate is less than or equal to a second preset bit error rate, and / or the received signal strength indicated by the received signal strength indicator is higher than or equal to the second preset signal strength, it indicates that the current signal quality is higher than or equal to the second preset signal quality. If this is maintained for a long time, there is a risk of SAR value exceeding the limit. Therefore, the controller controls the execution of a second adjustment process, gradually decreasing the transmission power. Thus, by cyclically executing the first and second adjustment processes based on the signal quality reflected by the first signal quality parameter, a dynamic balance between signal quality and SAR value can be maintained, effectively improving the overall signal quality and avoiding SAR value exceeding the limit.

[0037] In some embodiments, the first preset bit error rate may be a bit error rate value such as 10% or 12%, and the second preset bit error rate may be a bit error rate value such as 5% or 6%.

[0038] In some embodiments, the controller 3 is further configured to control the execution of a second power adjustment operation, wherein the second power adjustment operation includes: determining the transmission power of the radio frequency unit 2 within a preset duration, and comparing the transmission power within the preset duration with a first preset power value and a second preset power value, wherein the second preset power value is less than the first preset power value; when the transmission power within the preset duration is greater than the first preset power value, adjusting the transmission power of the radio frequency unit 2 to a preset power lower limit value, wherein the second preset power value is greater than the preset power lower limit value; and when the transmission power within the preset duration is less than the second preset power value, controlling the return to the execution of the first adjustment process.

[0039] That is, in some embodiments, the controller 3 is also used to perform a second power adjustment operation to determine whether the SAR value exceeds the standard and to perform corresponding control, thereby further monitoring and controlling the SAR value to avoid the SAR value from exceeding the standard.

[0040] In some embodiments, the first preset power value is the power value corresponding to the critical value of SAR exceeding the limit, and the preset power lower limit value is the minimum power value required to maintain the communication connection. Both the first preset power value and the preset power lower limit value can be obtained in advance through experimental testing.

[0041] The first power adjustment operation and the second power adjustment operation are executed in parallel. That is, while the controller 3 is executing the first power adjustment operation, it is also executing the second power adjustment operation to monitor and control the SAR value and prevent the SAR value from exceeding the standard.

[0042] According to current SAR safety regulations, whether a SAR value exceeds the limit is not determined by the transmit power at a single point in time, but rather by the transmit power over a period of time. A SAR value is considered to exceed the limit only when the transmit power over a preset period is greater than or equal to the first preset power value, which corresponds to the threshold for exceeding the SAR limit. Therefore, the controller 3 also controls the execution of a second power adjustment operation, comparing the transmit power over the preset period with both the first and second preset power values. If the transmit power over the preset period is greater than the first preset power value, the first power adjustment operation can be terminated. That is, regardless of whether the first power adjustment operation is in the first or second adjustment process, the transmit power of the radio frequency unit 2 is adjusted to the preset lower power limit, effectively preventing the SAR value from exceeding the limit. Conversely, if the transmit power over the preset period is less than the second preset power value, the controller returns to the first adjustment process, thus restarting the first power adjustment operation and balancing antenna radiation performance.

[0043] The preset duration may vary depending on the safety regulations of different regions. For example, according to the safety regulations of the FCC (Federal Communications Commission), the preset duration may be 100 seconds, while according to the safety regulations of the European Union, the preset duration may be 360 ​​seconds.

[0044] In some embodiments, the transmit power within the preset duration is the average transmit power within the preset duration. The first preset power value is a preset average power value, and the second preset power value is another preset average power value that is less than the first preset power value. The controller 3 determines the cumulative transmit power of multiple transmit powers of the radio frequency unit 2 sampled at a preset sampling interval within the preset duration, and divides the cumulative transmit power by the number of samplings to obtain the average transmit power within the preset duration.

[0045] In some embodiments, the first preset power value may be the average power value corresponding to the critical value of the SAR value exceeding the standard.

[0046] That is, in some embodiments, the transmit power within the preset duration is the average transmit power within the preset duration, the first preset power value is the average power value corresponding to the critical value of SAR value exceeding the standard, and the second preset power value is the average power value less than the first preset power value. Thus, the average transmit power can be compared to determine whether the SAR value exceeds the standard.

[0047] In some embodiments, the transmit power within the preset duration is the cumulative transmit power of multiple transmit powers of the radio frequency unit 2 sampled at a preset sampling interval within the preset duration, wherein the first preset power value is a preset total power value, and the second preset power value is another preset total power value that is less than the first preset power value.

[0048] In some embodiments, the first preset power value is the total power value corresponding to the critical value of the SAR value exceeding the standard.

[0049] That is, in some embodiments, the transmit power within the preset duration can also be the cumulative transmit power of multiple transmit powers of the radio frequency unit 2 sampled at a preset sampling interval within the preset duration, i.e., the total transmit power. The first preset power value is the total power value corresponding to the critical value of SAR value exceeding the standard, and the second preset power value is the total power value less than the first preset power value. Thus, the total transmit power can also be compared to determine whether the SAR value exceeds the standard.

[0050] Specifically, suppose that a total of n samples are taken within the preset duration (n is a positive integer greater than or equal to 1), and the power value obtained from the i-th sample is Power_stepi (1≤i≤n). Let the first preset power value be Power_limit1 and the second preset power value be Power_limit2. Then, the controller 3 compares the transmission power within the preset duration with the first preset power value and the second preset power value respectively. If Formula 1 is satisfied, the controller determines that the transmission power within the preset duration is greater than the first preset power value; and if Formula 2 is satisfied, the controller determines that the transmission power within the preset duration is less than the second preset power value. Formulas 1 and 2 are shown below.

[0051] Formula 1:

[0052] Power_step1+Power_step2+...+Power_stepn>Power_limit1;

[0053] Formula 2:

[0054] Power_step1+Power_step2+...+Power_stepn <Power_limit2。

[0055] In this application, the preset sampling interval can be a time interval of 1 second or 2 seconds, and the controller 3 controls the periodic sampling at the preset sampling interval. The preset duration can be a preset duration prior to the current sampling time; that is, each time the controller performs sampling, it calculates whether the transmit power within the preset duration prior to the current sampling time is greater than the first preset power value corresponding to the SAR value exceeding the threshold, thereby determining whether there is a current SAR value exceeding the limit.

[0056] In some embodiments, when the time elapsed before the current sampling time has not reached the preset time elapsed, for example, when the electronic device 100 has just started operating in the preset frequency band, the total time elapsed before the preset time elapsed is not yet the preset time elapsed. In this case, the controller 3 accumulates the sampled transmission power, that is, it sums it up, until the time elapsed before the current sampling time reaches the preset time elapsed. Then, the average transmission power or the cumulative transmission power within the aforementioned preset time elapsed can be obtained. Then, it is compared with the first preset power value and the second preset power value, and the corresponding operation is performed according to the comparison result.

[0057] In some embodiments, when the transmit power of the controller 3 is greater than or equal to the first preset power value within a preset time period, adjusting the transmit power of the radio frequency unit 2 to a preset power lower limit value may include: directly adjusting the transmit power of the radio frequency unit to the preset power lower limit value when the transmit power is greater than or equal to the first preset power value within a preset time period, or reducing the transmit power of the radio frequency unit by a third preset power adjustment value every third preset time interval until the transmit power of the radio frequency unit is adjusted to the preset power lower limit value.

[0058] That is, in some embodiments, adjusting the transmission power of the radio frequency unit 2 to a preset power lower limit can be done by directly adjusting the current transmission power value of the radio frequency unit 2 to the preset power lower limit, or by reducing the transmission power of the radio frequency unit by a third preset power adjustment value every third preset time interval until the transmission power of the radio frequency unit is adjusted to the preset power lower limit.

[0059] In some embodiments, when the transmit power of the radio frequency unit is reduced by a third preset power adjustment value at a third preset time interval, the third preset power adjustment value may be greater than the second preset power adjustment value, and the third preset time may be shorter than the second preset time. Therefore, it can be reduced to the preset power lower limit value faster than the second adjustment process in the first adjustment operation, and the SAR value can be effectively avoided from exceeding the standard.

[0060] The at least one antenna 1 may be one antenna or at least two antennas. The at least one target antenna in the at least one antenna 1 may be part or all of the at least one antenna 1, or it may be one antenna or at least two antennas. In Figure 1, the at least one antenna 1 is illustrated as an example.

[0061] In some embodiments, the first preset power value, the second preset power value, etc., can be pre-stored in the electronic device 100. The controller 3 can obtain the pre-stored first preset power value and the second preset power value, compare the transmission power within a preset time period with the first preset power value and the second preset power value, and perform the aforementioned operation based on the comparison result.

[0062] In some embodiments, when there are multiple antennas 1, the first preset power value and the second preset power value may also include multiple values, each corresponding to one of the multiple antennas 1. That is, the electronic device 100 may pre-store the first preset power value and the second preset power value corresponding to each antenna 1, and the first preset power value and the second preset power value corresponding to different antennas 1 may be different. The controller 3 may determine the first preset power value and the second preset power value corresponding to the target antenna based on the target antenna currently transmitting and receiving electromagnetic wave signals, i.e., the currently working target antenna, and then compare the transmission power within a preset time period with the first preset power value and the second preset power value, and perform the aforementioned operation based on the comparison result.

[0063] Furthermore, the electronic device 100 may pre-store a correspondence between antennas and preset power values, defining a one-to-one correspondence between multiple antennas and multiple first preset power values ​​and multiple second preset power values. The controller 3 can determine the first preset power value and the second preset power value corresponding to the target antenna currently transmitting and receiving electromagnetic waves based on the correspondence, then compare the transmission power within a preset time period with the first preset power value and the second preset power value, and perform the aforementioned operations based on the comparison result.

[0064] Please refer to Figure 2, which is a schematic plan view of a portion of the structure of an electronic device 100 in some embodiments of this application. As shown in Figure 2, the at least one antenna 1 includes at least two antennas 1, the radio frequency unit 2 is selectively connected to the at least two antennas 1, and the controller 3 is further configured to control the radio frequency unit 2 to connect to at least one target antenna 1, so as to receive and / or transmit electromagnetic wave signals in a preset frequency band through the at least one target antenna 1.

[0065] That is, in some embodiments, the at least one antenna 1 includes at least two antennas 1, both of which support the reception and / or transmission of electromagnetic wave signals in a preset frequency band. The at least one target antenna 1 may be a portion of the at least one antenna 1. The controller 3 may control the radio frequency unit 2 to connect with at least one target antenna 1 so as to receive and / or transmit electromagnetic wave signals in a preset frequency band through the at least one target antenna 1.

[0066] Figure 2 illustrates two antennas 1. Obviously, in some embodiments, the at least one antenna 1 may also include other numbers of antennas, such as three, four, etc.

[0067] In some embodiments, when the first signal quality parameter of at least one target antenna currently receiving and / or transmitting electromagnetic wave signals in a preset frequency band reflects that the current signal quality is lower than a first preset signal quality, the controller 3 controls the radio frequency unit 2 to switch to connect with other antennas, and when it is determined that the first signal quality parameters of all antennas reflect that the current signal quality is lower than the first preset signal quality, the controller controls the execution of a first power adjustment operation.

[0068] That is, in some embodiments, when the first signal quality parameter of at least one target antenna currently receiving and / or transmitting electromagnetic wave signals in a preset frequency band reflects that the current signal quality is lower than the first preset signal quality, the controller 3 controls the radio frequency unit 2 to first switch to connect with other antennas, and then receive and / or transmit electromagnetic wave signals in the preset frequency band through other antennas. During the process of receiving and / or transmitting electromagnetic wave signals in the preset frequency band through other antennas, the controller 3 can also acquire the first signal quality parameters of other antennas, and when it is determined that the first signal quality parameters of other antennas reflect that the current signal quality is lower than the first preset signal quality, it continues to acquire the first signal quality parameters of other antennas until it is determined that the first signal quality parameters of all antennas reflect that the current signal quality is lower than the first preset signal quality, before controlling the execution of the first power adjustment operation.

[0069] Therefore, in some embodiments, since the signal quality of the different antennas when receiving and / or transmitting electromagnetic wave signals is different, when the first signal quality parameter of at least one target antenna currently receiving and / or transmitting electromagnetic wave signals in a preset frequency band reflects that the current signal quality is lower than the first preset signal quality, the radio frequency unit 2 is first controlled to switch to connect with other antennas. If the signal quality of other antennas is better, the first power adjustment operation can be omitted, which helps to save computing resources.

[0070] In some embodiments, the at least two antennas 1 are disposed at different locations of the electronic device 100, and the beam directions of the at least two antennas are different. The controller 3 selects at least one target antenna from the at least two antennas 1 according to the different states of the electronic device, and controls the radio frequency unit 2 to connect with at least one target antenna 1 so as to receive and / or transmit electromagnetic wave signals of a preset frequency band through the at least one target antenna 1.

[0071] That is, in some embodiments, signal quality is largely affected by beam direction. The at least two antennas 1 are located at different positions of the electronic device 100, and the beam directions of the at least two antennas are different. Therefore, the signal quality varies when different antennas receive and / or transmit electromagnetic wave signals. The controller 3 selects at least one target antenna from the at least two antennas 1 according to the different states of the electronic device, and controls the radio frequency unit 2 to connect with at least one target antenna 1 to receive and / or transmit electromagnetic wave signals in a preset frequency band through the at least one target antenna 1. This allows the antenna to be more suitable for the current state of the electronic device to receive and / or transmit electromagnetic wave signals in the preset frequency band, which is beneficial to improving communication performance.

[0072] As shown in Figure 2, the electronic device 100 includes a top end D11, a bottom end D12, and two opposite side ends D13 and D14. The at least two antennas 1 include at least one first antenna 11 and at least one second antenna 12. Both the at least one first antenna 11 and the at least one second antenna 12 support the transmission and reception of electromagnetic wave signals in the preset frequency band. The at least one first antenna 11 is disposed at the top end D11 of the electronic device 100, and the at least one second antenna 12 is disposed at the side end of the electronic device 100, for example, at the side end D14 as shown in Figure 2. The electronic device 100 has two states: a head-and-hand state and a state away from the head. When the electronic device 100 is in the head-and-hand state, the controller 3 controls the radio frequency unit 2 to connect with at least a portion of the antennas in the at least one first antenna 11 to receive and / or transmit electromagnetic wave signals in a preset frequency band through the at least a portion of the antennas in the at least one first antenna 11. When the electronic device 100 is in the head-and-hand state, the controller 3 controls the radio frequency unit 2 to connect with at least a portion of the antennas in the at least one second second antenna 12 to receive and / or transmit electromagnetic wave signals in a preset frequency band through the at least a portion of the antennas in the at least one second second antenna 12.

[0073] The "head and hand state" refers to the state where the electronic device 100 is held and close to the head, while the "away from head state" can include both the state where the electronic device 100 is held and away from the head and the state where it is not held and away from the head. In this application, "close to head" can mean that the distance between the electronic device 100 and the user's head is less than a first preset distance, such as less than or equal to 5 centimeters, etc., while "away from head" can mean that the distance between the electronic device 100 and the user's head is greater than a second preset distance, such as greater than 5 centimeters, 10 centimeters, etc.

[0074] Since the at least one first antenna 11 is located at the top D11 of the electronic device 100, and the at least one second antenna 12 is located at the side of the electronic device 100, when the electronic device 100 is in a "head and hand" position, the performance of the first antenna 11 located at the top D11 of the electronic device 100 degrades due to contact with the head, resulting in a significant impact on communication performance. However, when the antenna is located away from the head, the at least one first antenna 11, being located at the top D11 of the electronic device 100, achieves better radiation performance. As for the at least one second antenna 12 located at the side of the electronic device 100, its impact is relatively small when the electronic device 100 is in the "head and hand" position. Therefore, in this application, when the electronic device 100 is in a state away from the head, the controller 3 controls the radio frequency unit 2 to connect with at least a portion of the antennas in the at least one first antenna 11 to receive and / or transmit electromagnetic wave signals in a preset frequency band through at least a portion of the antennas in the at least one first antenna 11. And when the electronic device 100 is in a head-and-hand state, the controller controls the radio frequency unit 2 to connect with at least a portion of the antennas in the at least one second second antenna 12 to receive and / or transmit electromagnetic wave signals in a preset frequency band through at least a portion of the antennas in the at least one second second antenna 12. This allows for better radiation performance when the electronic device 100 is in different states.

[0075] In Figure 2, the at least one first antenna 11 and the at least one second antenna 12 are illustrated as an example. That is, in Figure 2, the at least one antenna 1 includes a first antenna 11 disposed at the top D11 of the electronic device 100 and a second antenna 12 disposed at the side D14 of the electronic device 100.

[0076] Please refer to Figure 3, which is another planar schematic diagram of the electronic device 100 in some embodiments of this application. The difference between Figure 3 and Figure 2 is that the at least one second antenna 12 may include two, one second antenna 12 is disposed at the side end D13 of the electronic device 100, and the other second antenna 12 is disposed at the side end D14 of the electronic device 100.

[0077] Therefore, by providing multiple second antennas 12 located in different positions, the controller 3 can further control the RF unit 2 to connect to different second antennas 12 or to all second antennas 12 depending on whether the hand is held with the left or right hand, thereby further improving communication performance in the head-and-hand state. For example, since the coverage area of ​​the side ends D13 and D14 differs between left-hand and right-hand holding, when the current head-and-hand state is either left-hand or right-hand holding, the controller can control the connection to the second antenna 12 on the side end with the smaller coverage area, thereby reducing the area of ​​the second antenna 12 touched by the human body and improving communication performance. Alternatively, the controller can control the RF unit 2 to connect to all second antennas 12, thus improving communication performance in the head-and-hand state regardless of the holding position.

[0078] In Figures 2 and 3, only the first antenna 11 and the second antenna 12 are schematically shown. The first antenna 11 and the second antenna 12 can be any antenna structure that can support the preset frequency band.

[0079] In this application, the use of directional terms such as "top" and "bottom" when describing the electronic device 100 is primarily based on the orientation of the device when held and used by the user. "Top" refers to the position facing the top of the electronic device 100, and "bottom" refers to the position facing the bottom. This does not imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation on the orientation of the electronic device 100 in a real-world application scenario. In some embodiments, the bottom end D12 of the electronic device 100 is the end with a headphone jack and a USB port, and the top end D11 of the electronic device 100 is the opposite end to the end with the headphone jack and USB port. For example, the top end D11 of the electronic device 100 is the end with a camera.

[0080] The at least one antenna 12 is disposed on the side of the electronic device 100 and may be disposed close to the top D11 of the electronic device 100, so that the electronic device 100 is not easily held by the hand when held by the user.

[0081] Please refer to Figure 4, which is another planar schematic diagram of an electronic device 100 in some embodiments of this application. As previously described, the electronic device 100 includes an opposing top end D11, a bottom end D12, and two opposing side ends D13 and D14. As shown in Figure 4, the at least two antennas 1 include at least one first antenna 11, one second antenna 12, and one third antenna 13. In some embodiments, the at least one first antenna 11 supports the transmission and reception of electromagnetic wave signals in the preset frequency band, one of the second antenna 12 and the third antenna 13 supports the reception of electromagnetic wave signals in the preset frequency band, and the other of the second antenna 12 and the third antenna 13 supports the transmission of electromagnetic wave signals in the preset frequency band. The at least one first antenna 11 is disposed at the top D11 of the electronic device 100, the second antenna 12 is disposed at the side end of the electronic device 100, and the third antenna 13 is disposed at the back of the electronic device 100. Alternatively, the at least one first antenna 11 is disposed at the top D11 of the electronic device 100, and the second antenna 12 and the third antenna 13 are disposed at different positions on the side end of the electronic device 100. The electronic device 100 has two states: a head-and-hand state and a state away from the head. When the electronic device 100 is in the head-and-hand state, the controller 3 controls the radio frequency unit 2 to connect with at least one portion of the antennas in the first antenna 11 to receive and transmit electromagnetic wave signals in a preset frequency band through the portion of the antennas in the first antenna 11. When the electronic device 100 is in the head-and-hand state and is receiving electromagnetic wave signals in the preset frequency band, the controller 3 controls the radio frequency unit 2 to connect with at least one of the second antenna 12 and the third antenna 13 to receive electromagnetic wave signals in the preset frequency band through the second antenna 12 and the third antenna 13. When the electronic device 100 is in the head-and-hand state and is transmitting electromagnetic wave signals in the preset frequency band, the controller 3 controls the radio frequency unit 2 to connect with at least the other of the second antenna 12 and the third antenna 13 to transmit electromagnetic wave signals in the preset frequency band through the other of the second antenna 12 and the third antenna 13.

[0082] Therefore, in some embodiments, the at least two antennas 1 may include at least one first antenna 11 that simultaneously supports the transmission and reception of electromagnetic wave signals in the preset frequency band, and may also include a second antenna 12 and a third antenna 13, wherein one of the second antenna 12 and the third antenna 13 supports the reception of electromagnetic wave signals in the preset frequency band, and the other of the second antenna 12 and the third antenna 13 supports the transmission of electromagnetic wave signals in the preset frequency band. Thus, by having one of the second antenna 12 and the third antenna 13 support the reception of electromagnetic wave signals in the preset frequency band, and by having the other of the second antenna 12 and the third antenna 13 support the transmission of electromagnetic wave signals in the preset frequency band, transmission and reception can be performed separately by antennas located at different positions, thereby ensuring the communication quality of transmission and reception and avoiding SAR values ​​exceeding the limit.

[0083] In some embodiments, the second antenna 12 specifically supports the reception of electromagnetic wave signals in the preset frequency band, the third antenna 13 supports the transmission of electromagnetic wave signals in the preset frequency band, and at least one first antenna 11 is disposed at the top D11 of the electronic device 100, the second antenna 12 is disposed at the side of the electronic device 100, and the third antenna 13 is disposed at the back of the electronic device 100. Therefore, since the third antenna 13 is disposed at the back of the electronic device 100, when the electronic device 100 is in a human head and hand position and is transmitting electromagnetic wave signals in the preset frequency band, controlling the radio frequency unit 2 to connect at least to the third antenna 13, so that the transmission of electromagnetic wave signals in the preset frequency band via the third antenna 13 located at the back of the electronic device 100, will keep the transmitted electromagnetic wave signals away from the human body, thus avoiding exceeding the SAR value limit.

[0084] In some embodiments, the second antenna 12 and the third antenna 13 may also be disposed at different positions on the side of the electronic device 100. For example, the second antenna 12 and the third antenna 13 may be disposed at the two side ends D13 and D14 of the electronic device 100 respectively, and the beam direction of the third antenna 13 is biased towards the back side of the electronic device 100. Thus, when the electronic device 100 is in the human head and hand state and the electronic device 100 transmits electromagnetic wave signals in the preset frequency band, controlling the radio frequency unit 2 to be connected to at least the third antenna 13 so as to transmit electromagnetic wave signals in the preset frequency band through the third antenna 13 can also effectively avoid the SAR value from exceeding the standard.

[0085] In some embodiments, when the third antenna 13 is disposed on the back of the electronic device 100, the third antenna 13 may be a patch antenna disposed on the back cover of the electronic device 100, for example, the third antenna 13 may be attached to the inner surface of the back cover of the electronic device 100. In some embodiments, when the third antenna 13 is disposed on the back of the electronic device 100, the third antenna 13 may also be a camera metal decorative ring, that is, the third antenna 13 may share the structure of the camera metal decorative ring. This is beneficial for cost savings and for reducing the size of the electronic device 100.

[0086] In some embodiments, when the second antenna 12 and the third antenna 13 are disposed on the side of the electronic device 100, they can be disposed near the top D11 of the electronic device 100, so that the electronic device 100 is not easily held by the hand when held by the user.

[0087] As shown in Figures 2-4, in some embodiments, the electronic device 100 further includes a switch module 4, wherein the switch module 4 is connected between the radio frequency unit 2 and the at least one antenna 1, and the switch module 4 is used to selectively establish an electrical connection between the radio frequency unit 2 and at least one target antenna among the at least one antenna 1.

[0088] For example, as shown in Figure 2, the switch module 4 is connected between the radio frequency unit 2 and the first antenna 11 and the second antenna 12, for selectively establishing an electrical connection between the radio frequency unit 2 and the first antenna 11 or the second antenna 12. As shown in Figure 3, the switch module 4 is connected between the radio frequency unit 2 and the first antenna 11 and the two second antennas 12, for selectively establishing an electrical connection between the radio frequency unit 2 and at least one of the first antenna 11 and the two second antennas 12. As shown in Figure 4, the switch module 4 is connected between the radio frequency unit 2 and the first antenna 11, the second antenna 12, and the third antenna 13, for selectively establishing an electrical connection between the radio frequency unit 2 and at least one of the first antenna 11, the second antenna 12, and the third antenna 13.

[0089] The switch module 4 may include at least one switch 41, which establishes an electrical connection between the radio frequency unit 2 and at least one target antenna among the at least one antenna 1. For example, as shown in Figures 2-4, the at least one switch 41 of the switch module 4 may include multiple single-pole single-throw switches SW1, each of which is connected between the radio frequency unit 2 and an antenna 1. Thus, by having the multiple single-pole single-throw switches in corresponding on or off states, an electrical connection between the radio frequency unit 2 and at least one target antenna among the at least one antenna 1 can be established.

[0090] In some embodiments, at least one switch 41 of the switch module 4 may also be a single-pole multi-throw switch. The fixed end of the single-pole multi-throw switch is connected to the radio frequency unit 2, and each free end of the single-pole multi-throw switch is connected to a corresponding antenna 1. The throwing end of the single-pole multi-throw switch is used to switch the connection between the fixed end of the radio frequency unit 2 and different free ends, so that the radio frequency unit 2 is connected to different antennas 1.

[0091] In some embodiments, the controller 3 is used to control the connection between the radio frequency unit 2 and at least one target antenna via the switch module 4. The controller 3 may be connected to at least one switch 41 of the switch module 4, and by controlling the at least one switch 41 to a corresponding state, an electrical connection can be established between the radio frequency unit 2 and at least one target antenna among the at least one antenna 1.

[0092] In some embodiments, the preset frequency band may be a satellite communication frequency band, and the at least one antenna 1 is an antenna that supports satellite communication. Obviously, in some embodiments, the preset frequency band may also be other frequency bands, such as frequency bands under cellular communication networks, such as mid-to-high frequency bands, high frequency bands, etc.

[0093] Please refer to Figure 5, which is another planar schematic diagram of the electronic device 100 in some embodiments of this application. In some embodiments, the preset frequency band may be a satellite communication frequency band, and the preset frequency band includes a transmitting frequency band and a receiving frequency band, which are different. For example, the preset frequency band includes a transmitting frequency band of 1980–2010 MHz and a receiving frequency band of 2017–2200 MHz.

[0094] In some embodiments, as shown in FIG5, the electronic device 100 may further include a combiner 5, wherein the combiner 5 may be connected between the switch module 4 and the second antenna 12 and the third antenna 13, wherein the switch module 4 is used to select to establish an electrical connection between the radio frequency unit 2 and the first antenna 11 or to establish an electrical connection between the radio frequency unit 2 and the combiner 5.

[0095] The equivalent electrical lengths of the second antenna 12 and the third antenna 13 are different. For example, when the second antenna 12 supports the reception of electromagnetic wave signals in the preset frequency band and the third antenna 13 supports the transmission of electromagnetic wave signals in the preset frequency band, the equivalent electrical length of the second antenna 12 satisfies the resonance requirement in the receiving frequency band, and the equivalent electrical length of the third antenna 13 satisfies the resonance requirement in the transmitting frequency band. Therefore, since the preset frequency band includes different transmitting and receiving frequency bands, and the equivalent electrical lengths of the second antenna 12 and the third antenna 13 respectively satisfy the resonance requirements of the receiving and transmitting frequency bands, when the switching module 4 establishes an electrical connection between the radio frequency unit 2 and the combiner 5, the conduction of the receiving channel and the transmitting channel can be simultaneously achieved through the combiner 5. Since the equivalent electrical lengths of the second antenna 12 and the third antenna 13 respectively meet the resonance requirements of the receiving and transmitting frequency bands, after the switching module 4 establishes the electrical connection between the radio frequency unit 2 and the combiner 5, when transmitting the electromagnetic wave signal, it will only be transmitted through the third antenna 13, and when receiving the electromagnetic wave signal, it will only be received through the second antenna 12.

[0096] Therefore, in the structure shown in Figure 5, the switch module 4 may only need to include two single-pole single-throw switches or one single-pole double-throw switch, which is beneficial to the simplification of the structure of the switch module 4.

[0097] Figures 2-5 are schematic diagrams showing the electronic device 100 viewed from its rear side, i.e., the side of the electronic device 100 away from the display screen. In Figures 2-5, the back cover of the electronic device 100 is omitted. In Figures 4 and 5, when the third antenna 13 is located on the back cover of the electronic device 100, only the third antenna 13 is shown, and the back cover is omitted.

[0098] Please refer to Figure 6, which is a plan view illustrating a further portion of the structure of the electronic device 100 in some embodiments of this application. Specifically, Figure 6 may be a plan view illustrating a more specific structure in Figure 2.

[0099] As shown in Figures 2 and 6 above, the at least one antenna 1 includes a first antenna 11 and a second antenna 12. The first antenna 11 includes a first radiating stub 111 and a first parasitic stub 112, and the second antenna 12 includes a second radiating stub 121 and a second parasitic stub 122. The first radiating stub 111 includes a first open terminal 111a and a first ground terminal 111b, the first parasitic stub 112 includes a second open terminal 112a and a second ground terminal 112b, the second radiating stub 121 includes a third open terminal 121a and a third ground terminal 121b, and the second parasitic stub 122 includes a fourth open terminal 122a and a fourth ground terminal 122b.

[0100] Specifically, the first open end 111a of the first radiating branch 111 and the second open end 112a of the first parasitic branch 112 are arranged close to each other and spaced apart, and the first radiating branch 111 and the first parasitic branch 112 are coupled. The third open end 121a of the second radiating branch 121 and the fourth open end 122a of the second parasitic branch 122 are arranged close to each other and spaced apart, and the second radiating branch 121 and the second parasitic branch 122 are coupled.

[0101] The first radiating stub 111 includes a first feed point F1, and the second radiating stub 121 includes a second feed point F2. The first feed point F1 is located between the first open-circuit terminal 111a and the first ground terminal 111b of the first radiating stub 111, and the second feed point F2 is located between the third open-circuit terminal 121a and the third ground terminal 121b of the second radiating stub 121. The radio frequency unit 2 is selectively electrically connected to either the first feed point F1 of the first radiating stub 111 or the second feed point F2 of the second radiating stub 121 to excite the first antenna 11 to receive and / or transmit electromagnetic wave signals in a preset frequency band, or to excite the second antenna 12 to receive and / or transmit electromagnetic wave signals in a preset frequency band.

[0102] The overall equivalent electrical length of the first radiating stub 111 and the first parasitic stub 112 satisfies the resonance requirement of resonance in the preset frequency band. When the radio frequency unit 2 is electrically connected to the first feed point F1 of the first radiating stub 111, the radio frequency unit 2 excites the first radiating stub 111 and couples the excitation of the first parasitic stub 112, so that the first radiating stub 111 and the first parasitic stub 112 resonate as a whole in the preset frequency band, thereby enabling the first antenna 11 to receive and / or transmit electromagnetic wave signals in the preset frequency band. The overall equivalent electrical length of the second radiating stub 121 and the second parasitic stub 122 also meets the resonance requirement of resonance in the preset frequency band. When the radio frequency unit 2 is electrically connected to the second feed point F2 of the second radiating stub 121, the radio frequency unit 2 excites the second radiating stub 121 and couples to excite the second parasitic stub 122, so that the second radiating stub 121 and the second parasitic stub 122 resonate as a whole in the preset frequency band, so that the second antenna 12 can receive and / or transmit electromagnetic wave signals in the preset frequency band.

[0103] The overall equivalent electrical length of the first radiating branch 111 and the first parasitic branch 112 can be the sum of their individual equivalent electrical lengths, for example, the sum of their physical lengths. Alternatively, the overall equivalent electrical length of the first radiating branch 111 and the first parasitic branch 112 can also be the sum of their equivalent electrical lengths under the cooperation of the corresponding matching units. Similarly, the overall equivalent electrical length of the second radiating branch 121 and the second parasitic branch 122 can be the sum of their individual equivalent electrical lengths, for example, the sum of their physical lengths. Alternatively, the overall equivalent electrical length of the second radiating branch 121 and the second parasitic branch 122 can also be the sum of their equivalent electrical lengths under the cooperation of the corresponding matching units.

[0104] As shown in Figure 6, the electronic device 100 further includes a first matching unit M1 and a second matching unit M2. The first parasitic stub 112 also includes a first grounding point G1, and the second parasitic stub 122 includes a second grounding point G2. The first grounding point G1 is located between the second open-circuit terminal 112a and the second grounding terminal 112b, and the second grounding point G2 is located between the fourth open-circuit terminal 122a and the fourth grounding terminal 122b. The first matching unit M1 is connected between the first grounding point G1 of the first parasitic stub 112 and ground GND, and is used to match and adjust the first antenna 11 so that the overall equivalent electrical length of the first radiating stub 111 and the first parasitic stub 112 meets the resonance requirement in the preset frequency band. The second matching unit M2 is connected between the second grounding point G2 of the second parasitic stub 122 and ground GND, and is used to match and adjust the second antenna 12 so that the overall equivalent electrical length of the second radiating stub 121 and the second parasitic stub 122 meets the resonance requirement in the preset frequency band. That is, in some embodiments, the overall equivalent electrical length of the first radiating branch 111 and the first parasitic branch 112 is the sum of the equivalent electrical lengths under the cooperation of the first matching unit M1, and the overall equivalent electrical length of the second radiating branch 121 and the second parasitic branch 122 is the sum of the equivalent electrical lengths under the cooperation of the second matching unit M2.

[0105] The first matching unit M1 and the second matching unit M2 may include capacitors and / or inductors, or may include multiple capacitors and / or multiple inductors. For example, they may also include multiple capacitors connected in series or in parallel, or multiple inductors connected in series or in parallel, or capacitors and inductors connected in series, or capacitors and inductors connected in parallel, etc.

[0106] As shown in Figure 6, in some embodiments, the first parasitic branch 112 and the second parasitic branch 122 are located between the first radiating branch 111 and the second radiating branch 121. The second grounding terminal 112b of the first parasitic branch 112 and the fourth grounding terminal 122b of the second parasitic branch 122 are connected together and grounded together. That is, the first parasitic branch 112 and the second parasitic branch 122 can share a branch. This is beneficial to the compactness of the overall structure.

[0107] As shown in Figure 6, the second parasitic stub 122 also includes a third feed point F3, which is located between the second ground point G2 and the fourth open-circuit terminal 122a. The third feed point F3 is also connected to the radio frequency unit 2. The second parasitic stub 122 generally forms an IFA (inverted F antenna). Under the excitation of the radio frequency unit 2, the second parasitic stub 122 can support the transmission and reception of electromagnetic wave signals in another frequency band. This other frequency band is different from the preset frequency band. Therefore, more frequency bands can be supported through the structure of the first antenna 11 and the second antenna 12, satisfying the multi-frequency band requirement without increasing the structural size. The other frequency band can be a mid-high frequency, intermediate frequency, or high frequency band.

[0108] The equivalent electrical length of the second parasitic stub 122 can be 1 / 4 of the wavelength corresponding to another frequency band, and the resonance occurs in that other frequency band. The equivalent electrical length of the second parasitic stub 122 can be its own equivalent electrical length, for example, approximately equal to its own physical length, or it can be the equivalent electrical length in cooperation with the aforementioned second matching unit M2.

[0109] Obviously, in some embodiments, the first parasitic stub 112 may also include a corresponding feed point, which may be connected to the radio frequency unit 2. The first parasitic stub 112 as a whole also forms an IFA antenna. Under the excitation of the radio frequency unit 2, the first parasitic stub 112 can support the transmission and reception of electromagnetic wave signals in other frequency bands. The other frequency bands may be different from the preset frequency band and the other frequency band, thereby further increasing the number of supported frequency bands. The equivalent electrical length of the first parasitic stub 112 may be 1 / 4 of the wavelength corresponding to the other frequency band, and it resonates in the other frequency band. The equivalent electrical length of the first parasitic stub 112 may be its own equivalent electrical length, for example, approximately equal to its own physical length, or it may be the equivalent electrical length under the cooperation of the aforementioned first matching unit M1.

[0110] As shown in Figure 6, the first radiating branch 111 and the second radiating branch 121 can share branches with other branches. The first grounding terminal 111b of the first radiating branch 111 is grounded to isolate the first radiating branch 111 from other branches sharing the branch. The third grounding terminal 121b of the second radiating branch 121 is grounded to isolate the second radiating branch 121 from other branches sharing the branch.

[0111] In some embodiments, the first radiating branch 111 and the second radiating branch 121 may also be separate branches, that is, there is a gap between the first grounding end 111b of the first radiating branch 111 and the adjacent branch, and there is also a gap between the third grounding end 121b of the second radiating branch 121 and the adjacent branch. In some embodiments, the first parasitic branch 112 and the second parasitic branch 122 may also be separate branches, that is, there may be a gap between the second grounding end 112b of the first parasitic branch 112 and the adjacent branch, such as the second parasitic branch 122, and there may be a gap between the fourth grounding end 122b of the second parasitic branch 122 and the adjacent branch, such as the first parasitic branch 112.

[0112] In some embodiments, when the preset frequency band is a satellite communication frequency band, and the frequency ranges corresponding to the transmitting and receiving frequency bands included in the satellite communication frequency band are different, the first matching unit M1 and the second matching unit M2 can be adjustable matching units, thereby enabling the matching and tuning of the transmitting and receiving frequency bands respectively.

[0113] In Figure 6, the switch module 4 is illustrated as an example, which includes multiple single-pole single-throw switches.

[0114] Please refer to Figure 7, which is a schematic diagram of the structure of the first matching unit M1 in some embodiments of this application. In some embodiments, the first matching unit M1 includes a plurality of matching branches M10, each matching branch M10 including a matching element M11 and a matching switch SW2 connected in series, and the plurality of matching branches M10 are connected in parallel between the first grounding point G1 of the first parasitic branch 112 and ground GND.

[0115] Among them, the matching parameter values ​​of the matching element M11 included in different matching branches M10 are different. When the matching switch SW2 in different matching branches M10 is turned on, the matching parameter values ​​of the first matching unit M1 as a whole are different.

[0116] Therefore, when the preset frequency band is a satellite communication frequency band, and the frequency ranges corresponding to the transmitting and receiving frequency bands included in the satellite communication frequency band are different, when the first antenna 11 transmits electromagnetic wave signals in the preset frequency band, the matching switch SW2 of the corresponding matching branch M10 in the first matching unit M1 can be turned on, while other matching switches SW2 are turned off. This causes the first matching unit M1 to present the corresponding matching parameter value, ensuring that the overall equivalent electrical length of the first radiating stub 111 and the first parasitic stub 112, in cooperation with the first matching unit M1, resonates in the transmitting frequency band. When the first antenna 12 receives electromagnetic wave signals in the preset frequency band, the matching switch SW2 of another corresponding matching branch M10 in the first matching unit M1 can be turned on, causing the first matching unit M1 to present another corresponding matching parameter value. This ensures that the overall equivalent electrical length of the first radiating stub 111 and the first parasitic stub 112, in cooperation with the first matching unit M1, resonates in the receiving frequency band.

[0117] Figure 7 illustrates the first matching unit M1, which includes two matching branches M10. Clearly, the first matching unit M1 can include other numbers of matching branches M10, such as three matching branches M10, four matching branches M10, etc.

[0118] Wherein, when the preset frequency band is a satellite communication frequency band, and the frequency ranges corresponding to the transmitting and receiving frequency bands included in the satellite communication frequency band are different, the second matching unit M2 can also be an adjustable matching unit, and the structure of the second matching unit M2 is the same as the structure of the first matching unit M1 shown in Figure 7. That is, the second matching unit M2 can also include multiple matching branches M10, each matching branch M10 including a matching element M11 and a matching switch SW2 connected in series, and the multiple matching branches M10 are connected in parallel between the second grounding point G2 of the second parasitic stub 122 and ground GND. For a more specific structure, please refer to the structure of the first matching unit M1 shown in Figure 7. Thus, through the second matching unit M2, the overall equivalent electrical length of the second radiating stub 121 and the second parasitic stub 122 can also satisfy resonance in the transmitting and receiving frequency bands, respectively.

[0119] When the second parasitic branch 122 or the first parasitic branch 112 can also resonate in another frequency band, the second matching unit M2 or the first matching unit M1 can also perform matching adjustment on the second parasitic branch 122 or the first parasitic branch 112 respectively, so that the second parasitic branch 122 and the first parasitic branch 112 can resonate in the corresponding frequency band respectively.

[0120] Obviously, in some embodiments, when the preset frequency band is a single frequency band, that is, a frequency band that can be covered by the center frequency of the first antenna 11 and the second antenna 12 resonating in that frequency band, or when the preset frequency band is a satellite communication frequency band and the transmitting frequency band and the receiving frequency band of the satellite communication frequency band are the same, the first matching unit M1 and the second matching unit M2 may also be non-adjustable matching units.

[0121] Please refer to Figure 8, which is another planar schematic diagram illustrating a further portion of the structure of the electronic device 100 in some embodiments of this application. Specifically, Figure 8 may be a planar schematic diagram illustrating a more specific structure in Figure 3.

[0122] As mentioned above, in some embodiments, the at least one second antenna 12 may include two, one second antenna 12 disposed at the side end D13 of the electronic device 100, and the other second antenna 12 disposed at the side end D14 of the electronic device 100. As shown in FIG8, the structure of the second antenna 12 disposed at the side end D14 of the electronic device 100 and the first antenna 12 is the same as the structure shown in FIG6 above; please refer to the relevant description in FIG6 for details.

[0123] As shown in Figure 8, the second antenna 12 located at side end D13 may include a fifth open-circuit terminal 12a and a fifth ground terminal 12b. The second antenna 12 at side end D13 includes a fourth feed point F4, located between the fifth open-circuit terminal 12a and the fifth ground terminal 12b. The second antenna 12 forms an IFA antenna structure. The fourth feed point F4 can be connected to the radio frequency unit 2, and the second antenna 12, under the excitation of the radio frequency unit 2, supports the transmission and reception of electromagnetic wave signals in a preset frequency band.

[0124] As shown in Figure 8, the fifth open-circuit terminal 12a of the second antenna 12 located at side end D13 can be positioned close to and spaced apart from adjacent branches. The fifth grounding terminal 12b of the second antenna 12 located at side end D13 can be connected to adjacent branches and share a branch with them, and is grounded through the fifth grounding terminal 12b while being spaced apart from each other. As shown in Figure 8, the branch adjacent to the fifth open-circuit terminal 12a of the second antenna 12 can be located at the apex of the electronic device 100, for example, at the apex formed by the connection of the top end D11 and the side end D13 as shown in Figure 8.

[0125] Please refer to Figure 9, which is another plan view illustrating a portion of the structure of the electronic device 100 in some embodiments of this application. Figure 9 may also be a plan view illustrating a more specific structure as shown in Figure 3.

[0126] The difference between the structures shown in Figures 9 and 8 is that the fifth grounding terminal 12b of the second antenna 12 located at side end D13 can be connected to an adjacent branch to share a branch, and the branch where the second antenna 12 is located can be located at the apex of the electronic device 100, for example, at the apex formed by the connection of the top end D11 and the side end D13 as shown in Figure 8. The fifth open-circuit terminal 12a of the second antenna 12 located at side end D13 is close to and spaced apart from the adjacent branches, and as shown in Figure 9, the branch adjacent to the fifth open-circuit terminal 12a of the second antenna 12 can be entirely located on the side end D13 of the electronic device 100.

[0127] In Figures 8 and 9, the switch module 4 is illustrated using multiple single-pole single-throw switches as an example.

[0128] Thus, either the structure shown in Figures 8 and 9 can be used to realize a structure of at least one first antenna 11 and multiple second antennas 12.

[0129] Please refer to Figure 10, which is another planar schematic diagram illustrating a portion of the structure of the electronic device 100 in some embodiments of this application. Specifically, Figure 10 is a planar schematic diagram illustrating a more specific structure in Figure 4, and specifically illustrates the specific structure of the first antenna 11 and the second antenna 12.

[0130] As shown in Figure 10, the at least two antennas 1 include a first antenna 11, a second antenna 12 and a third antenna 13. As shown in Figure 10, the structure of the first antenna 11 and the second antenna 12 can be the same as the structure shown in Figure 6 above. For details, please refer to the relevant description in Figure 6 above.

[0131] The third antenna 13 and other structures are described in detail in Figure 4 above.

[0132] Please refer to Figure 11, which is a further schematic plan view illustrating a portion of the structure of the electronic device 100 in some embodiments of this application. Specifically, Figure 11 is a schematic plan view illustrating a more specific structure in Figure 5, and specifically illustrates the specific structure of the first antenna 11 and the second antenna 12.

[0133] As shown in Figure 11, the at least two antennas 1 include a first antenna 11, a second antenna 12 and a third antenna 13, and also include a combiner 5. As shown in Figure 11, the structure of the first antenna 11 and the second antenna 12 can be the same as the structure shown in Figure 6 above. For details, please refer to the relevant description of Figure 6 above.

[0134] For details regarding the third antenna 13 and other structures such as the combiner 5, please refer to the relevant description in Figure 5 above.

[0135] In some embodiments, as described above, the at least one antenna 1 may include at least two antennas, wherein in some embodiments, the at least two antennas 1 are disposed at different locations of the electronic device 100, and the beam directions of the at least two antennas 1 are different. The controller 3 is further configured to acquire a second signal quality parameter when the at least one target antenna currently connected to the radio frequency unit 2 is receiving and / or transmitting electromagnetic wave signals, and when the second signal quality parameter reflects that the current signal quality is lower than a second preset signal quality, control the radio frequency unit 2 to switch to connecting to other antennas 1.

[0136] That is, in some embodiments, the controller 3 is further configured to acquire a second signal quality parameter when at least one currently connected target antenna is receiving and / or transmitting electromagnetic wave signals, and control the radio frequency unit 2 to switch to connect with other antennas 1 when the second signal quality parameter reflects that the current signal quality is lower than a second preset signal quality. Thus, when the signal quality of the currently connected antenna 1 is poor, the radio frequency unit 2 is controlled to switch to connect with other antennas 1, thereby changing the signal quality by switching antennas 1.

[0137] In some embodiments, the second signal quality parameter includes a signal-to-noise ratio (SNR) and / or a received signal strength indication. When the SNR is lower than a preset SNR and / or the received signal strength indicated by the received signal strength indication is lower than a third preset signal strength, the controller 3 determines that the current signal quality is lower than a second preset signal quality.

[0138] That is, in some embodiments, the second signal quality parameter includes signal-to-noise ratio (SNR) and received signal strength indication, which reflect signal quality. The SNR may include both received SNR and transmitted SNR. A higher SNR indicates better signal quality, and a higher received signal strength indication also reflects better signal quality. Therefore, it is possible to determine whether the current signal quality is lower than a second preset signal quality based on these second signal quality parameters, including SNR and received signal strength indication.

[0139] The second preset signal quality may be the same as or different from the first preset signal quality.

[0140] In some embodiments, the second signal quality parameter may also include the bit error rate.

[0141] In some embodiments, when the current second signal quality parameter reflects that the current signal quality is lower than the second preset signal quality, the controller 3 determines the current optimal beam connection direction, determines the antenna 1 with the largest gain in the optimal beam connection direction based on the pre-determined gain of each antenna 1 in each direction, and controls the radio frequency unit 2 to switch to connect with the antenna 1 with the largest gain in the optimal beam connection direction.

[0142] That is, in some embodiments, the controller 3 controls the radio frequency unit 2 to switch to connect with other antennas 1, which can be controlling the radio frequency unit 2 to switch to connect with the antenna 1 with the highest gain in the optimal beam connection direction. Therefore, since the signal quality of the antenna 1 with the highest gain in the optimal beam connection direction is the best, communication performance can be effectively improved.

[0143] In some embodiments, as described above, the preset frequency band may be a satellite communication frequency band. The optimal beam connection direction may be the direction in which the beam is directly facing the satellite. The controller 3 can determine the optimal beam direction by acquiring the geographic coordinates of the current location of the electronic device 100, a preset satellite azimuth angle, and the current placement orientation of the electronic device 100. The preset satellite azimuth angle may be the spatial coordinates of the satellite relative to the Earth, and the geographic coordinates may be latitude and longitude. Therefore, the direction of the satellite relative to the electronic device 100 can be roughly determined based on the geographic coordinates of the electronic device 100 and the preset satellite azimuth angle. Then, combined with the current placement orientation of the electronic device 100, the optimal beam connection direction under that placement orientation can be determined. For example, the direction of the satellite relative to the electronic device 100 can be the direction of the electronic device 100 in a preset attitude. For example, it can be the direction of the satellite relative to the electronic device 100 when the electronic device 100 is in a horizontal placement attitude with the display screen facing upward. Then, by determining the angle deviation between the current placement attitude of the electronic device 100 and the preset attitude, the direction of the satellite relative to the electronic device 100 in the placement attitude can be obtained, which is the optimal beam connection direction.

[0144] The gain of each antenna 1 in each direction, obtained in advance, can be the gain of each antenna 1 in each direction obtained by testing the electronic device 100 in a preset posture. The controller 3 can convert the gain of each antenna 1 in each direction obtained by testing the electronic device 100 in the preset posture into the gain in each direction under the current placement posture, and then determine the antenna 1 corresponding to the maximum gain in the optimal beam connection direction, thus obtaining the antenna 1 with the maximum gain in the optimal beam connection direction. The conversion of the gain of each antenna 1 in each direction obtained by testing the electronic device 100 in the preset posture into the gain in each direction under the current placement posture can be achieved by using the spatial angular relationship between the current placement posture and the preset posture to convert the directions of the electronic device 100 in the preset posture into the directions of the electronic device 100 in the current placement posture. Therefore, by using the correspondence before and after the conversion and the gain of each antenna 1 in each direction obtained by testing the electronic device 100 in the preset posture, the gain in each direction under the current placement posture can be obtained.

[0145] In some embodiments, when the current second signal quality parameter reflects that the current signal quality is lower than the second preset signal quality, the controller 3 can also control the radio frequency unit 2 to switch to the connection of other antennas 1 in sequence, and obtain the second signal quality parameter of each antenna 1 that reflects the signal quality, and finally control the radio frequency unit 2 to connect to the antenna with the best signal quality.

[0146] That is, in some embodiments, when the current second signal quality parameter reflects that the current signal quality is lower than the second preset signal quality, the controller 3 can also control the antenna 1 to rotate and detect the second signal quality parameter of the currently working antenna 1. After obtaining the second signal quality parameters of all antennas 1 that reflect the signal quality, the controller 3 determines the second signal quality parameter corresponding to the best signal quality based on the second signal quality parameters of all antennas 1, and determines the antenna 1 with the second signal quality parameter corresponding to the best signal quality as the final connected antenna 1. Thus, in the current scenario, the controller can switch to the antenna 1 with the best signal quality to improve communication performance.

[0147] In some embodiments, the controller 3 is further configured to, when determining that the transmission power within a preset time period is less than or equal to the second preset power value, and if it is determined that the current body azimuth angle is in an unconnectable region, control the output of a prompt message to prompt the user to rotate. Here, the current body azimuth angle being in an unconnectable region may mean that the user's body is located between the satellite and the electronic device 100, and the signal is blocked, resulting in being in an unconnectable region. The prompt message may include vibration prompts, voice prompts, display prompts, etc.

[0148] Please refer to Figure 12, which is a further structural block diagram of part of the internal structure of an electronic device 100 in some embodiments of this application. As shown in Figure 12, the electronic device 100 includes at least one antenna 1, a radio frequency unit 2, a controller 3, and also includes a sensor 6.

[0149] The sensor 6 can be used to detect the placement posture of the electronic device 100 and generate a corresponding sensing signal. The controller 3 is connected to the sensor 6 and is used to receive the sensing signal generated by the sensor 6 to determine the placement posture of the electronic device 100. The placement posture includes front-facing, back-facing, head-and-hand position, and position away from the head, etc.

[0150] For example, in some embodiments, the sensor 6 may include a proximity sensor such as an infrared sensor. When the controller 3 receives a sensing signal generated by the proximity sensor detecting a human body approaching the electronic device 100, it determines that a human body is currently detected approaching the electronic device 100. The sensor 6 may be disposed on one side of the display screen of the electronic device 100, close to the top D11 of the electronic device 100. When the distance between the human body and the proximity sensor itself is less than a preset distance, it determines that a human body is detected approaching the electronic device 100 and generates a sensing signal. Here, determining that a human body is currently detected approaching the electronic device 100 mainly refers to the head of the person approaching the electronic device 100. Generally, users only bring the front of the electronic device 100, that is, the side of the display screen, close to their head or other body parts when making a phone call or similar scenarios. Therefore, the sensor 6 may be disposed on one side of the display screen of the electronic device 100. When the distance between the human body and the sensor 6 itself is less than a preset distance, it indicates that the human head is close to the electronic device 100, that is, in a state of being close to the human head, and a corresponding sensing signal is generated.

[0151] The sensor 6 may also include an accelerometer or other attitude sensors. The controller 3 may also detect the placement of the electronic device 100, such as whether it is facing up or facing down, through the attitude sensors.

[0152] In some embodiments, the controller 3 may be connected to the switch 41 in the switch module 4, and by controlling the switching 41 in the switch module 4 to turn on or off, the connection between the radio frequency unit 2 and the at least one antenna 1 can be controlled.

[0153] When the electronic device 100 further includes the aforementioned first matching unit M1 and second matching unit M2, and the first matching unit M1 and second matching unit M2 include matching switches SW2, the controller 3 can also be connected to these matching switches SW2 to control the on or off of the matching switches SW2.

[0154] Among them, the switch 41 in the switch module 4 and the matching switch SW2, etc., are digitally controlled switches, such as MOSFETs, BJT transistors, etc., and can be in the on or off state when receiving the corresponding level signal from the controller 3.

[0155] Please refer to Figure 13, which is a simplified structural block diagram of the radio frequency unit 2 of the electronic device 100 in some embodiments of this application. As shown in Figure 13, in some embodiments, the radio frequency unit 2 includes a radio frequency transceiver 21 and a power amplifier 22. The radio frequency transceiver 21 includes a transmitter 211 and a receiver 212. The radio frequency transceiver 21 is used to transmit radio frequency signals through the transmitter 211. The power amplifier 22 is connected between the at least one antenna 1 and the transmitter 211, and is used to amplify the power of the radio frequency signal transmitted by the transmitter 211 of the radio frequency transceiver 21 before transmitting it to the at least one currently operating target antenna 1, and then transmitting it out through the at least one target antenna 1, which is the aforementioned electromagnetic wave signal of the preset frequency band. The receiver 212 is used to receive the electromagnetic wave signal of the preset frequency band received by the at least one target antenna 1.

[0156] The transmit power of the radio frequency unit 2 is the output power after power amplification by the power amplifier 22. The controller 3 can control the increase or decrease of the transmit power of the radio frequency unit 2 by increasing or decreasing the amplification factor of the power amplifier 22.

[0157] Figure 13 simply illustrates one antenna 1 and one transceiver channel, namely one transmitting channel and one receiving channel. The transmitting channel is the channel through which the power amplifier 22 outputs the signal, and the receiving channel is the channel through which the electromagnetic wave signal received by the antenna is transmitted to the receiving end 212 of the radio frequency transceiver 21.

[0158] Obviously, the electronic device 100 may include other numbers of antennas 1, and the radio frequency unit 2 may also have multiple transceiver channels. For example, the electronic device 100 may include three antennas 1, and the radio frequency unit 2 may have three corresponding transceiver channels, each corresponding to one antenna 1. As another example, the electronic device 100 may include three antennas 1, and the radio frequency unit 2 may include two transceiver channels, where one transceiver channel is connected to one antenna 1, and the other transceiver channel can be switched to connect to two other antennas 1 via a corresponding switch. As yet another example, the electronic device 100 may include multiple antennas 1, while the radio frequency unit 2 may have only one transmit channel, i.e., including a power amplifier 22. Furthermore, the radio frequency unit 2 may include multiple receive channels, each connected to one antenna 1. Thus, no switching is required during reception, while during transmission, the power amplifier 22 can be switched to connect to different antennas via a switch, allowing selection of different antennas 1 for transmission.

[0159] Therefore, Figure 13 is merely a simplified illustration, and the radio frequency architecture of the electronic device 100 of this application can be configured as needed.

[0160] In some embodiments, as shown in Figures 2-6 above, the electronic device 100 further includes a frame B1, and the at least one antenna 1, such as the first antenna 11 and the second antenna 12, is disposed on the frame B1 of the electronic device 100 and is spaced apart by gaps X1.

[0161] In some embodiments, the frame B1 of the electronic device 100 is a metal frame, and the at least one antenna 1 is a metal frame segment formed by opening the gap X1 in the metal frame of the electronic device 100.

[0162] In some other embodiments, the frame B1 of the electronic device 100 is a non-metallic frame, the at least one antenna 1 is a metal segment disposed in the frame of the electronic device 100, and the at least one antenna 1 is spaced apart by the gap X1.

[0163] That is, in some other embodiments, the frame B1 of the electronic device 100 may also be a non-metallic frame with low conductivity, such as plastic, ceramic, etc. The at least one antenna 1 is a metal segment disposed in the frame B1 of the electronic device 100.

[0164] The at least one antenna 1 may be embedded in the frame of the electronic device 100 or disposed on the inner side of the frame of the electronic device 100.

[0165] As shown in Figures 2-6, in some embodiments, the at least one antenna 1 is elongated, such as a straight strip or a bent strip.

[0166] As shown in Figures 2-6, the electronic device 100 also includes a motherboard 101, wherein the aforementioned radio frequency unit 2, controller 3, etc., may be disposed on the motherboard 101. The aforementioned ground GND may be the ground on the motherboard 101. The first ground terminal 111b and other grounding terminals may be connected to the ground on the motherboard 101 for grounding.

[0167] As shown in Figures 2-6, the electronic device 100 also includes a middle frame 102, which supports structures such as a display screen and serves as the ground for the entire device. The ground on the motherboard 101 is connected to the middle frame 102 to provide ground potential. The first grounding terminal 111b and other grounding terminals can also be directly electrically connected to the middle frame 102 for grounding.

[0168] Therefore, the electronic device 100 of this application can effectively ensure communication performance and avoid exceeding the SAR value limit, thereby improving the user experience.

[0169] The electronic device 100 in this application can be any electronic device with an antenna, such as a mobile phone, tablet computer, or laptop computer.

[0170] The controller 3 may be a central controller, a communication processing chip, etc.

[0171] Please refer to Figure 14, which is a flowchart of an antenna power control method according to an embodiment of this application. In some embodiments, the power control method is applied to an electronic device, which includes a radio frequency unit and at least one antenna. The radio frequency unit is connected to the at least one antenna and is used to receive and / or transmit electromagnetic wave signals in a preset frequency band through at least one target antenna among the at least one antenna. The antenna power control method includes the following steps:

[0172] 151: Obtain first signal quality parameters when the at least one target antenna receives and / or transmits electromagnetic wave signals; and

[0173] 152: When it is determined that the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, a first power adjustment operation is executed, wherein the first power adjustment operation includes: a first adjustment process: increasing the transmit power of the radio frequency unit by a first preset power value at a first preset time interval until a first preset condition is met; and a second adjustment process: when the first preset condition is met, decreasing the transmit power of the radio frequency unit by a second preset power adjustment value at a second preset time interval until it is determined that the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality again, and then returning to execute the first adjustment process.

[0174] Therefore, the antenna power control method of this application, when the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, controls the execution of a first power adjustment operation including a first adjustment process and a second adjustment process. In the first adjustment process, the signal quality is improved by gradually increasing the transmission power to enhance the antenna radiation performance, which can avoid the SAR value exceeding the standard due to an excessive increase in transmission power in a short period of time. When the first preset condition is met, the transmission power of the radio frequency unit is reduced by a second preset power adjustment value at second preset time intervals, which can also avoid the SAR value exceeding the standard while avoiding an excessive reduction in signal quality. Furthermore, when the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, this application returns to executing the first adjustment process. Thus, by cyclically executing the first adjustment process and the second adjustment process, the overall signal quality can be effectively improved, and the SAR value exceeding the standard can be avoided.

[0175] In some embodiments, the first preset condition includes the transmission power reaching a preset power upper limit or the first signal quality parameter reflecting the current signal quality being higher than or equal to a second preset signal quality, wherein the second preset signal quality is higher than the first preset signal quality.

[0176] The first signal quality parameter includes a bit error rate and / or a received signal strength indication. Determining that the first signal quality parameter reflects a current signal quality lower than a first preset signal quality includes: determining that the current signal quality is lower than the first preset signal quality when the bit error rate is greater than or equal to the first preset bit error rate, and / or the received signal strength indicated by the received signal strength indication is lower than the first preset signal strength. In some embodiments, the first signal quality parameter reflecting a current signal quality higher than or equal to a second preset signal quality includes: the bit error rate is less than or equal to the second preset bit error rate, and / or the received signal strength indicated by the received signal strength indication is higher than or equal to the second preset signal strength; wherein the second preset signal strength is higher than the first preset signal strength, and the second preset bit error rate is less than the second preset bit error rate.

[0177] Please refer to Figure 15, which is another flowchart of an antenna power control method according to some embodiments of this application. The order of the steps in the flowchart in this application does not represent the order of execution. In some embodiments, the antenna power control method includes the steps:

[0178] 161: Obtain first signal quality parameters when the at least one target antenna receives and / or transmits electromagnetic wave signals; and

[0179] 162: When it is determined that the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, a first power adjustment operation is executed; and

[0180] 163: Control the execution of the second power regulation operation.

[0181] Steps 161 and 162 correspond to steps 151 and 152 above, and more details can be found in Figure 15. Steps 161-162 and 163 are executed in parallel; that is, while executing steps 161-162, a second power adjustment operation is performed simultaneously. This second power adjustment operation is also performed to monitor and control the SAR value, preventing it from exceeding the limit.

[0182] Please refer to Figure 16, which is a sub-flowchart of step 163 in Figure 15 in some embodiments of this application. In some embodiments, step 163 may include:

[0183] 1631: Determine the transmission power of the radio frequency unit within a preset time period, and compare the transmission power within the preset time period with a first preset power value and a second preset power value, wherein the second preset power value is less than the first preset power value;

[0184] 1632: When the transmit power within a preset time period is greater than the first preset power value, the transmit power of the radio frequency unit is adjusted to a preset power lower limit value, wherein the second preset power value is greater than the preset power lower limit value; and

[0185] 1633: When the transmission power within a preset time period is less than the second preset power value, the control returns to execute the first adjustment process.

[0186] In some embodiments, the first preset power value is the power value corresponding to the critical value of the SAR value exceeding the limit, and the preset power lower limit value is the minimum power value required to maintain the communication connection.

[0187] That is, in some embodiments, the antenna power control method further includes: controlling the execution of a second adjustment operation, wherein the second adjustment operation includes: determining the transmit power of the radio frequency unit within a preset duration, and comparing the transmit power within the preset duration with a first preset power value and a second preset power value, wherein the first preset power value is the power value corresponding to the critical value of SAR exceeding the limit, and the second preset power value is less than the first preset power value; when it is determined that the transmit power within the preset duration is greater than the first preset power value, adjusting the transmit power of the radio frequency unit to a preset power lower limit value, wherein the preset power lower limit value is the minimum power value required to maintain the communication connection, and the second preset power value is greater than the preset power lower limit value; and when it is determined that the transmit power within the preset duration is less than the second preset power value, controlling the return to the execution of the first adjustment process. The first power adjustment operation and the second power adjustment operation are executed in parallel, thereby monitoring and controlling the SAR value by simultaneously executing the second power adjustment operation, thus preventing the SAR value from exceeding the limit.

[0188] In some embodiments, the transmit power within a preset duration is the average transmit power within the preset duration. The first preset power value is a preset average power value, and the second preset power value is another preset average power value less than the first preset power value. The controller determines the cumulative transmit power of multiple transmit powers of the radio frequency unit sampled at preset sampling intervals within the preset duration, and divides the cumulative output power by the number of samplings to obtain the average transmit power within the preset duration. In some embodiments, the first preset power value may be the average power value corresponding to a critical value where the SAR value exceeds the limit.

[0189] In some embodiments, the transmit power within the preset duration is the cumulative transmit power of multiple transmit powers of the radio frequency unit sampled at a preset sampling interval within the preset duration, wherein the first preset power value is a preset total power value, and the second preset power value is another preset total power value that is less than the first preset power value. In some embodiments, the first preset power value is the total power value corresponding to a critical value for exceeding the SAR value limit.

[0190] In some embodiments, when the transmit power within a preset time period is greater than the first preset power value, adjusting the transmit power of the radio frequency unit to a preset power lower limit includes: when the transmit power within a preset time period is greater than the first preset power value, directly adjusting the transmit power of the radio frequency unit to the preset power lower limit, or reducing the transmit power of the radio frequency unit by a third preset power adjustment value every third preset time interval until the transmit power of the radio frequency unit is adjusted to the preset power lower limit.

[0191] In some embodiments, the method further includes the step of: obtaining the first preset power value, the second preset power value, etc.

[0192] In some embodiments, when there are multiple antennas, the first preset power value and the second preset power value may also each include multiple values, and each corresponds to one of the multiple antennas. Obtaining the first preset power value and the second preset power value includes: determining the first preset power value and the second preset power value corresponding to the target antenna currently transmitting and receiving electromagnetic waves, based on the correspondence between the target antenna and the preset power values. The correspondence between the antenna and the preset power values ​​defines a one-to-one correspondence between multiple antennas and multiple first preset power values ​​and multiple second preset power values.

[0193] In some embodiments, the at least one antenna includes at least two antennas, the radio frequency unit is selectively connected to the at least two antennas, and the antenna power control method further includes: controlling the radio frequency unit to connect to at least one target antenna to receive and / or transmit electromagnetic wave signals in a preset frequency band through the at least one target antenna.

[0194] In some embodiments, the at least one antenna includes at least two antennas, and the radio frequency unit is selectively connected to the at least two antennas. When it is determined that the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality, the first power adjustment operation is controlled to be performed, including: when the first signal quality parameter of at least one target antenna currently receiving and / or transmitting electromagnetic wave signals in a preset frequency band reflects that the current signal quality is lower than the first preset signal quality, controlling the radio frequency unit to switch to connection with other antennas; and when it is determined that the first signal quality parameters of all antennas reflect that the current signal quality is lower than the first preset signal quality, controlling the first power adjustment operation to be performed.

[0195] In some embodiments, the at least two antennas are disposed at different locations of the electronic device, and the beam directions of the at least two antennas are different. Controlling the radio frequency unit to connect with at least one target antenna to receive and / or transmit electromagnetic wave signals of a preset frequency band through the at least one target antenna includes: selecting the at least one target antenna from the at least two antennas according to the different states of the electronic device, and controlling the radio frequency unit to connect with the at least one target antenna to receive and / or transmit electromagnetic wave signals of a preset frequency band through the at least one target antenna.

[0196] In some embodiments, the electronic device includes a top end, a bottom end, and two opposite side ends. The at least two antennas include at least one first antenna and at least one second antenna.

The computer-readable storage medium may be the aforementioned memory 8, or other storage media such as an optical disc, USB flash drive, flash memory card, etc.

[0211] For example, the program causes the computer to perform the following steps: acquiring a first signal quality parameter when the at least one target antenna receives and / or transmits electromagnetic wave signals; and when it is determined that the first signal quality parameter reflects that the current signal quality is lower than a first preset signal quality, controlling the execution of a first power adjustment operation, wherein the first power adjustment operation includes: a first adjustment process: increasing the transmission power of the radio frequency unit by a first preset power adjustment value at a first preset time interval until a first preset condition is met; and a second adjustment process: when the first preset condition is met, decreasing the transmission power of the radio frequency unit by a second preset power adjustment value at a second preset time interval until it is determined that the first signal quality parameter reflects that the current signal quality is lower than the first preset signal quality again, and then returning to execute the first adjustment process.

[0213] By employing the antenna power control method and electronic device 100 of this application, when the first signal quality parameter indicates that the current signal quality is lower than the first preset signal quality, a first power adjustment operation, including a first adjustment process and a second adjustment process, is executed. During the first adjustment process, the signal quality is improved by gradually increasing the transmission power to enhance the antenna radiation performance, thus avoiding a sudden increase in transmission power that could lead to SAR values ​​exceeding the limit. Furthermore, when the first preset condition is met, the transmission power of the radio frequency unit is reduced by a second preset power adjustment value at second preset time intervals, which also avoids both SAR values ​​exceeding the limit and excessive signal quality degradation. Moreover, when the first signal quality parameter indicates that the current signal quality is lower than the first preset signal quality, this application returns to executing the first adjustment process. Therefore, by cyclically executing the first and second adjustment processes, the overall signal quality can be effectively improved, and SAR values ​​exceeding the limit can be avoided.
