[0019] The electronic device and antenna control method provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of the antenna structure of an electronic device provided in an embodiment of this application. Figure 1 As shown, the antenna structure of the electronic device includes a transceiver 101, a power amplifier (PA) 102, a low noise amplifier (LNA) 103, a duplexer 104, a coupler 105, a switching switch 106, multiple phase shifters 107, and at least one antenna 108. In this configuration, the first terminal of transceiver 101 is connected to the input terminal of PA102, the output terminal of PA102 is connected to the transmitting terminal of duplexer 104, the second terminal of transceiver 101 is connected to the output terminal of LNA103, the input terminal of LNA103 is connected to the receiving terminal of duplexer 104, the antenna terminal of duplexer 104 is connected to the input terminal of coupler 105, the output terminal of coupler 105 is connected to the moving terminal of switch 106, the coupling terminal of coupler 105 is connected to the third terminal of transceiver 101, and the multiple stationary terminals of switch 106 are connected one-to-one with the multiple phase shifters 107, and the multiple phase shifters 107 are connected to the at least one antenna 108. The multiple phase shifters 107 correspond to different usage scenarios, and the phase of each phase shifter 107 is matched with the corresponding usage scenario. The switching switch 106 connects the corresponding phase shifter 107 according to the usage scenario of the electronic device.

[0021] In this embodiment, the radio frequency and antenna paths in the overall operating state of the device are as follows: Figure 1 As shown, the antenna structure includes a transceiver 101, a PA 102, an LNA 103, a duplexer 104, a coupler 105, a switching switch 106, multiple phase shifters 107, and at least one antenna 108. The transceiver 101 receives and transmits radio frequency signals. The PA 102 amplifies the output signal of the transceiver 101 and transmits it to the antenna 108 for transmission. The LNA 103 amplifies the signal received by the antenna 108 and transmits it back to the transceiver 101. The duplexer 104 combines the transmission and reception frequency bands of the signal. The coupler 105 transmits power back to the transceiver 101 through a coupling path for power detection, thereby controlling the power output of the transceiver 101 to the PA 102, which also affects the power output of the PA 102 to the antenna 108. The antenna 108 transmits and receives signals. The at least one antenna 108 can be one or more antennas.

[0022] The power detection of transceiver 101 is transmitted back via coupler 105. The transmitted power FBRX is the output power of PA102 plus the fluctuation of the coupling coefficient of coupler 105. When antenna 108 is in a fixed standing wave condition, the coupling coefficient of coupler 105 fluctuates with the phase fluctuation of antenna 108. Specifically, as the phase fluctuates between 0 and 360°, the coupling coefficient of coupler 105 fluctuates in a sinusoidal shape due to reflection. Therefore, at a specific phase of antenna 108, the power of PA102 increases, which can improve coverage and throughput. To ensure that the transmitted power FBRX remains constant, PA102 adjusts its output power according to the magnitude of transmitted power FBRX. The smaller FBRX is, the greater the output power of PA102.

[0023] In this embodiment, a switching switch 106 and multiple phase shifters 107 are added between the coupler 105 and the antenna 108. The switching switch 106 can be a single-pole multi-throw switch, such as an SP4T. The ANT pin (moving terminal) of the coupler 105 is connected to the switching switch 106, and the multiple RF pins (stationary terminals) of the switching switch 106 are respectively connected to the multiple phase shifters 107. For example, RF1 pin is connected to phase shifter 1071, RF2 pin is connected to phase shifter 1072, RF3 pin is connected to phase shifter 1073, and RF4 pin is connected to phase shifter 1074. The switching switch 106 is used to switch the path of the phase shifter 1072 according to the usage scenario of the electronic device. The multiple phase shifters 107 correspond to different usage scenarios, and the phase of each phase shifter 107 is matched with its corresponding usage scenario. This allows the power returned by the coupler 105 to be minimized or reduced, thereby increasing the output power of PA102 and improving antenna performance.

[0024] Optionally, if the at least one antenna 108 is a single antenna, all of the plurality of phase shifters 107 are connected to the antenna 108.

[0025] In some embodiments, when the at least one antenna 108 is a single antenna, such as Figure 1 As shown, all of the multiple phase shifters 107 are connected to the antenna 108, thereby increasing the PA's output power without increasing the antenna efficiency by adjusting the phase of the antenna under the same return loss, thus improving coverage and throughput and enhancing the actual user experience.

[0026] Optionally, when the at least one antenna 108 is multiple antennas, the multiple phase shifters 107 are connected to the multiple antennas one-to-one, and the multiple antennas correspond to different usage scenarios.

[0027] In some embodiments, when the at least one antenna 108 is a plurality of antennas, such as Figure 2As shown, the multiple phase shifters 107 are connected one-to-one with the multiple antennas, that is, one phase shifter 107 is connected to one antenna 108, forming multiple paths. Different antennas and phase shifter paths correspond to different usage scenarios. For example, phase shifter 1071 is connected to antenna 1081, phase shifter 1072 is connected to antenna 1082, phase shifter 1073 is connected to antenna 1083, and phase shifter 1074 is connected to antenna 1084. The switching switch 106 switches to different phase shifter 107 and antenna 108 paths according to different usage scenarios of the electronic device. For example, phase shifter 1071 and antenna 1081 correspond to the antenna's free working state, that is, when the electronic device is in a space environment without hand obstruction, the switching switch 106 connects phase shifter 1071 and antenna 1081. In this way, without changing the antenna layout position, by adjusting the phase of different antennas in different usage scenarios, the antenna efficiency remains unchanged but the PA output power is increased, thereby improving coverage and throughput, and enhancing the actual user experience.

[0028] Optionally, the number of phase shifters 107 is four, and the multiple phase shifters 107 correspond to free space scene, single-handed grip scene, head-hand coupling scene and game grip scene respectively.

[0029] In some embodiments, the number of phase shifters 107 can be designed to be four, thereby forming four radio frequency paths with the antenna 108, which are used for four different usage scenarios. Specifically, these include free space scenario, one-handed grip scenario, head-hand coupling scenario, and gaming grip scenario. The free space scenario refers to the antenna being in an open environment without human contact or metal obstruction (i.e., free space), where the antenna radiating element is completely exposed to the air medium, such as the usage scenario where the user does not hold the antenna of the electronic device. The one-handed grip scenario refers to the antenna being held by a human with one hand, with the gripping part being the non-feed section of the antenna, and the hand not simultaneously touching the human head or other metal conductors, such as the usage scenario where the user holds the electronic device and operates it with one hand. The head-hand coupling scenario refers to the antenna being close to the human head (such as in a pin-to-ear call state), and the antenna being held by a human with one hand, such as the usage scenario where the user holds the electronic device to their ear for a call. The gaming grip scenario refers to the antenna being fixed in a symmetrical gripping manner with both hands, such as the usage scenario where the user holds the electronic device horizontally with both hands to play online games. For example, when antenna 1081 is in free state (corresponding to free space scenario), the RF1 pin of switch 106 is connected to phase shifter 1071; when antenna 1082 is in human hand state (corresponding to single-hand grip scenario), the RF2 pin of switch 106 is connected to phase shifter 1072; when antenna 1083 is in human head and hand state (corresponding to head and hand coupling scenario), the RF3 pin of switch 106 is connected to phase shifter 1073; and when antenna 1084 is in game hand state (corresponding to game grip scenario), the RF4 pin of switch 106 is connected to phase shifter 1074.

[0030] This effectively solves the problem of antenna performance degradation in different usage scenarios. By cleverly utilizing the load pull of the PA and adjusting the antenna phase through the phase shifter, the performance of the antenna in different usage scenarios is improved.

[0031] An electronic device according to an embodiment of this application includes an antenna structure, which includes a transceiver, a power amplifier (PA), a low-noise amplifier (LNA), a duplexer, a coupler, a switching switch, multiple phase shifters, and at least one antenna. The first terminal of the transceiver is connected to the input terminal of the PA, the output terminal of the PA is connected to the transmitting terminal of the duplexer, the second terminal of the transceiver is connected to the output terminal of the LNA, the input terminal of the LNA is connected to the receiving terminal of the duplexer, the antenna terminal of the duplexer is connected to the input terminal of the coupler, the output terminal of the coupler is connected to the moving terminal of the switching switch, the coupling terminal of the coupler is connected to the third terminal of the transceiver, multiple stationary terminals of the switching switch are connected one-to-one with the multiple phase shifters, and the multiple phase shifters are connected to the at least one antenna. The multiple phase shifters correspond to different usage scenarios, and the phase of each phase shifter matches the corresponding usage scenario. The switching switch connects the corresponding phase shifter according to the usage scenario of the electronic device. In this way, by adding a switching switch and multiple phase shifters between the coupler and the antenna, different phase shifters can be connected in different usage scenarios, and the phase of each phase shifter is matched with the corresponding usage scenario. This ensures that the power transmitted back through the coupler is small, thereby increasing the output power of the antenna structure and improving the antenna performance.

[0032] Please see Figure 3 , Figure 3 The flowchart of the antenna control method provided in the embodiments of this application is applied to the electronic devices in the foregoing embodiments, such as... Figure 3 As shown, the method includes the following steps: Step 301: When the electronic device is operating in the first usage scenario, control the switching switch to connect the first phase shifter, wherein the first phase shifter is the phase shifter among the plurality of phase shifters that corresponds to the first usage scenario, the phase of the first phase shifter is the target phase, and the target phase matches the first usage scenario.

[0033] The aforementioned first usage scenario can refer to one of the various usage scenarios of an electronic device, such as a free space scenario, a one-handed holding scenario, a head-hand coupling scenario, etc. The aforementioned first phase shifter refers to a phase shifter corresponding to the first usage scenario. The phase of each phase shifter can be pre-adjusted to match the corresponding usage scenario so that the electronic device can obtain higher PA output power or achieve the desired SAR derating under different usage scenarios.

[0034] When the electronic device is operating in the first usage scenario, the phase shifter corresponding to the first usage scenario can be switched on by the switching switch 106, so that the phase of the antenna can be adjusted by the phase shifter, so that the PA output power reaches the maximum or the desired SAR derating is achieved.

[0035] Optionally, before step 301, the method further includes: When the antenna structure is not connected to any phase shifter, the first power value returned by the coupler is obtained; When the electronic device is operating in the first usage scenario, the first phase shifter is connected through the switching switch, and N second power values ​​returned by the coupler are detected when the first phase shifter is in N different phases, respectively, wherein the N second power values ​​correspond one-to-one with the N phases, and N is an integer greater than 1; Based on the first power value and the N second power values, a target power value is determined, and the phase of the first phase shifter is adjusted to the target phase, which is the phase corresponding to the target power value.

[0036] In some embodiments, the phase of each phase shifter can be scanned in advance according to different usage scenarios to determine the target phase of each phase shifter in the corresponding usage scenario. This ensures that the antenna phase can be adjusted accordingly through the phase shifter in different usage scenarios to achieve the maximum PA output power or the desired SAR derating.

[0037] First, the power value FBRX value A transmitted back to the transceiver 101 through the coupler 105 under conductive conditions can be obtained. That is, when the switch 106 is not connected to any of the multiple phase shifters 107, the first power value transmitted back by the coupler 105 is detected through the third terminal of the transceiver 101.

[0038] Specifically, the second power value transmitted from the coupler 105 to the transceiver 101 can be detected separately under different phase conditions of the first phase shifter. Taking N phases respectively yields N corresponding second power values, such as the transmitted power values ​​B0, B1, B2, B3...B2 received by the transceiver 101 when the phase shifter is at 0°, 10°, 20°..., 350°, 360°. 35 B 36 .

[0039] Based on the detected first power value and N second power values, a suitable target power value can be determined by comparing the magnitude of each power value or by comparing the difference between the first power value and each second power value. For example, the target power value can be the minimum or smaller value among the first power value and N second power values, or it can be a second power value whose difference from the first power value is equal to a preset difference.

[0040] Based on the target power value, the corresponding phase can be determined, and the phase of the first phase shifter can be assigned to the phase corresponding to the target power value. This enables the return power in the current first usage scenario to be the target power value, thereby achieving the purpose of increasing the PA output power or achieving the purpose of derating the PA output power in a specific way.

[0041] Optionally, the N phases range from 0° to 360°, the difference between the i-th phase and the j-th phase is n, N = 360° / n, and i and j are adjacent positive integers.

[0042] In some embodiments, the first phase shifter can be scanned in steps n within the range of 0° to 360° to detect the return power at each phase. The value of n can be set according to actual needs; for example, a smaller value is used when higher accuracy is required. For instance, n = 10°, causing the phase φ of the first phase shifter to scan in 10° steps from 0° until it reaches 360°, while simultaneously recording the FBRX values ​​B0, B1, B2, B3…B in the transceiver 101. 35 B 36 .

[0043] In this way, by regularly scanning the phase of the phase shifter in all directions, it is possible to accurately find the phase corresponding to the minimum return power, which is beneficial to improving the antenna output power.

[0044] Optionally, determining the target power value based on the first power value and the N second power values ​​includes: By comparing the first power value and the N second power values, the minimum power value among the first power value and the N second power values ​​is determined to be the target power value.

[0045] In some embodiments, the minimum power value among the N second power values ​​compared to the first power value can be found by comparing the first power value with the N second power values. This minimum power value is then determined as the target power value. In this way, the phase corresponding to the minimum power value can be assigned to the first phase shifter, so that the return power in the current usage scenario is minimized, thereby maximizing the output power of PA102 and improving antenna performance.

[0046] For example, taking the antenna 108 operating in a free state as an example, the phase φ1 of the phase shifter 1071 starts from 0° and performs phase scanning in 10° steps until it cuts off at 360°, while simultaneously recording the FBRX values ​​B0, B1, B2, B3...B in the transceiver 101. 35 B 36 Then compare B0, B1, B2, B3...B 35 B36 Record the smallest value B among the 37 return power values ​​that is the smallest of the 37 return power values ​​compared to the first power value A. x (x=0,1….,36), this value corresponds to the maximum output power of PA102, and therefore assigns phase B to phase shifter 1071. x The corresponding phase value φ x When antenna 108 is in a human hand or human head hand state, phase shifter 1072 and phase shifter 1073 can determine the corresponding phase according to a similar process described above, and assign the corresponding phase value to the corresponding phase shifter to ensure that the output power of PA102 reaches the maximum.

[0047] To make the embodiments of this application clearer, a load pull diagram of actual whole-machine testing is provided, that is, a diagram showing the relationship between the return power value and the phase, as follows. Figure 4 As shown, the PA output power is the highest in the second quadrant and the PA output power is the lowest in the first quadrant, with the largest difference between the two being 2dB.

[0048] Optionally, determining the target power value based on the first power value and the N second power values ​​includes: Obtain the derating value of the specific absorption rate (SAR) required for the antenna structure; The differences between the N second power values ​​and the first power value are calculated respectively to obtain N differences, and the N differences correspond one-to-one with the N second power values; Determine the target difference value among the N differences that matches the SAR devaluation value, and determine the second power value corresponding to the target difference value as the target power value.

[0049] In other embodiments, this can be applied to SAR reduction scenarios. Specifically, based on the required SAR derating value, the difference between the first power value and the N second power values ​​can be compared to find the target difference that is the same as or closest to the required SAR derating value. The second power value corresponding to the target difference is determined as the target power value, and the phase corresponding to the target power value is assigned to the first phase shifter. In this way, a phase state suitable for antenna derating is found, and the purpose of reducing the antenna output power is achieved.

[0050] It should be noted that, due to the limitations of the coupler's directivity coefficient, this embodiment is only applicable to antennas with small derating, such as derating of less than 1.5dB.

[0051] This implementation method enables the control of PA output power to reduce SAR by adjusting the phase of different antennas in different usage scenarios without adding SAR detection circuits, while keeping antenna efficiency unchanged.

[0052] Optionally, the first usage scenario is any one of the following: free space scenario, single-handed grip scenario, head-hand coupling scenario, and game grip scenario.

[0053] In other words, the embodiments of this application are applicable to any of the various common usage scenarios of electronic devices, ensuring that the antenna can maintain high output power in different usage scenarios, thereby improving antenna performance. Among them, the free space scenario refers to the antenna being in an open environment without human contact or metal objects obstructing it (i.e., free space), in which case the antenna radiating element is completely exposed to the air medium, such as the usage scenario where the user does not hold the antenna of the electronic device to obstruct it; the one-handed holding scenario refers to the antenna being held by a human with one hand, the holding part being the non-feed section of the antenna, and the hand not simultaneously touching the human head or other metal conductors, such as the usage scenario where the user holds the electronic device and operates it with one hand; the head-hand coupling scenario refers to the antenna being close to the human head (such as in the case of a phone call held to the ear), and the antenna being held by a human with one hand, such as the usage scenario where the user holds the electronic device to their ear for a call; the gaming holding scenario refers to the antenna being fixed in a symmetrical two-handed holding manner, such as the usage scenario where the user holds the electronic device horizontally with both hands to play online games.

[0054] For example, when antenna 1081 operates in a free state (corresponding to a free space scenario), the RF1 pin of switch 106 is connected to phase shifter 1071. At this time, the output power of PA102 can be optimized in this scenario by adjusting the phase φ1 of phase shifter 1071. When antenna 1082 operates in a hand position (corresponding to a one-handed holding scenario), the RF2 pin of switch 106 is connected to phase shifter 1072. Due to the influence of the hand on the antenna, the phase of antenna 1082 changes. At this time, the output power of PA102 can be optimized in this scenario by adjusting the phase φ2 of phase shifter 1072. When antenna 1083 operates under a head position... When the hand is in hand mode (corresponding to the head-hand coupling scenario), the RF3 pin of the switch 106 is connected to the phase shifter 1073. Due to the influence of the human head and hand on the antenna, the phase of the antenna 1083 changes. At this time, the output power of PA102 can be optimized in this scenario by adjusting the phase φ3 of the phase shifter 1073. When the antenna 1084 is in game hand mode (corresponding to the game grip scenario), the RF4 pin of the switch 106 is connected to the phase shifter 1074. Due to the influence of the game hand on the antenna, the phase of the antenna 1084 changes. At this time, the output power of PA102 can be optimized in this scenario by adjusting the phase φ4 of the phase shifter 1074.

[0055] The antenna control method in this embodiment connects a first phase shifter via a switching switch when the electronic device is operating in a first usage scenario. The first phase shifter is one of the plurality of phase shifters corresponding to the first usage scenario, and its phase is a target phase that matches the first usage scenario. Thus, by switching the corresponding phase shifter according to the usage scenario, the antenna phase can be adjusted accordingly in different usage scenarios.
