[0002] This application claims priority to Chinese Patent Application No. 202410691275.8, filed in China on May 30, 2024, the entire contents of which are incorporated herein by reference. Technical Field

[0003] This application relates to the field of electronic product technology, specifically to an electronic device. Background Technology

[0004] Communication is a fundamental function of electronic products, and in recent years, related technologies have significantly improved and enhanced the communication capabilities of electronic products. For example, technologies such as RF enhancement chips, Lingxi antennas, and Huanyu signal amplifiers have comprehensively improved the performance of electronic products across all scenarios—including free-flowing, portrait-oriented handheld gaming, landscape-oriented gaming, and head-and-hand communication—by addressing hardware capabilities, antenna solutions, and software algorithms, thus meeting users' signal experience needs in extremely weak signal environments. On the other hand, the new national standard now controls the body specific absorption rate (bodySAR) of electronic products. For some frequency bands, while meeting bodySAR requirements, the total radiated power (TRP) will decrease by 1–3 dB compared to the past, posing a significant challenge to antenna engineers. Therefore, in related technologies, it is difficult for some electronic products to guarantee good antenna performance across all antenna frequency bands in various extreme scenarios. Summary of the Invention

[0005] This application provides an electronic device that can help improve antenna performance in various frequency bands.

[0006] In a first aspect, this application provides an electronic device, including a conductive frame and a first SAR sensor. The conductive frame is provided with a first antenna, a second antenna, and a third antenna. The first antenna and the second antenna operate in a first frequency band, and the third antenna operates in a second frequency band. The minimum value of the first frequency band is greater than the maximum value of the second frequency band. The conductive frame includes a first frame, a second frame, a third frame, and a fourth frame connected in sequence. The first frame is opposite to the third frame, the second frame is opposite to the fourth frame, and the length of the first frame is less than the length of the second frame.

[0007] The first frame has a first break, the second frame has a second break, and the second frame has a first grounding point and a second grounding point. The first grounding point and the second grounding point are located between the first break and the second break, and the second grounding point is located between the first grounding point and the second break. The first antenna includes a frame area between the first break and the first grounding point. The second antenna includes a frame area between the second grounding point and the second break. The third antenna includes at least a portion of the frame area in the second frame that extends from the second break toward the third frame.

[0008] The first SAR sensor includes a frame region in the conductive frame between the first break and the first grounding point. The first frame is the top frame of the electronic device. The distance between the second break and the third frame is a first distance, and the distance between the second break and the first frame is a second distance. The first distance is greater than the second distance.

[0009] In this embodiment, since the first SAR sensor includes the frame area between the first break and the first grounding point within the conductive frame, the first SAR sensor can be used for SAR detection of both the first antenna and the vicinity of the second antenna. When the first frame is the top frame of the electronic device, the electronic device can reduce the SAR of the antenna in areas where a person is near, based on the detection results of the first SAR sensor. This helps avoid the problem of reduced antenna power due to the proximity of a person, thus enabling the electronic device to have better antenna performance in free-scene and vertical handheld scenarios in the first frequency band. Simultaneously, since the first frame is the top frame of the electronic device, the distance between the second break and the third frame is greater than the distance between the second break and the first frame. That is, the second break is closer to the top frame than the bottom frame of the electronic device. Therefore, in vertical handheld, horizontal, and head-and-handed call scenarios, it is difficult for a person to hold the second break, thus enabling the electronic device to have better antenna performance in vertical, horizontal handheld, and head-and-handed call scenarios in the second frequency band.

[0024] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0025] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0026] The following description, in conjunction with the accompanying drawings, details an electronic device provided in this application through specific embodiments and application scenarios.

[0027] Please refer to Figure 1. This application embodiment provides an electronic device, which includes a conductive frame 100 and a first SAR sensor 104. The conductive frame 100 is provided with a first antenna 101, a second antenna 102, and a third antenna 103. The first antenna 101 and the second antenna 102 operate in a first frequency band, and the third antenna 103 operates in a second frequency band. The minimum value of the first frequency band is greater than the maximum value of the second frequency band. The conductive frame 100 includes a first frame 105, a second frame 106, a third frame 107, and a fourth frame 108 connected in sequence. The first frame 105 is opposite to the third frame 107, and the second frame 106 is opposite to the fourth frame 108. The length of the first frame 105 is less than the length of the second frame 106.

[0028] The first frame 105 has a first break 109, the second frame 106 has a second break 110, and the second frame 106 has a first grounding point 111 and a second grounding point 112. The first grounding point 111 and the second grounding point 112 are located between the first break 109 and the second break 110, and the second grounding point 112 is located between the first grounding point 111 and the second break 110. The first antenna 101 includes a frame area between the first break 109 and the first grounding point 111. The second antenna 102 includes a frame area between the second grounding point 112 and the second break 110. The third antenna 103 includes at least a portion of the frame area in the second frame 106 that extends from the second break 110 toward the third frame 107.

[0029] The first SAR sensor 104 includes a frame area in the conductive frame 100 between the first break 109 and the first grounding point 111. The first frame 105 is the top frame of the electronic device. The distance between the second break 110 and the third frame 107 is a first distance, and the distance between the second break 110 and the first frame 105 is a second distance. The first distance is greater than the second distance.

[0030] The aforementioned conductive frame 100 can be the metal frame of an electronic device. The aforementioned electronic device can be various handheld terminals with communication functions, such as mobile phones, tablets, etc.

[0031] The first frequency band mentioned above can be a middle high band (MHB) and the second frequency band mentioned above can be a low band (LB). For example, the range of the first frequency band can be 1710MHz-2690MHz and the range of the second frequency band can be 617MHz-960MHz.

[0032] The aforementioned first SAR sensor 104 may further include a SAR sensor integrated circuit (SARsensorIC), which can be electrically connected to any location in the frame region between the first break 109 and the first grounding point 111 to form the first SAR sensor 104. Furthermore, when the first SAR sensor 104 needs to be grounded, it needs to be grounded through the first capacitor 131 shown in FIG1.

[0033] It is understood that the first SAR sensor 104 can be used to perform SAR detection on the first antenna 101 and also to perform SAR detection on the vicinity of the second antenna 102. In this way, the electronic device can perform SAR reduction processing on the antenna in the area where a human body is close based on the detection results of the first SAR sensor 104.

[0034] Please refer to Figure 1. The first border 105 is the border at the top of the electronic device, the third border 107 is the border at the bottom of the electronic device, the second border 106 is the right border of the rear cover view of the electronic device, and the fourth border 108 is the left border of the rear cover view of the electronic device.

[0035] It is understandable that the excitation positions corresponding to each of the above antennas can be set according to actual needs.

[0036] Referring to Figure 3, when the first grounding position and the second grounding position are directly connected, the first SAR sensor 104 may also include the frame area between the first grounding point 111 and the second break 110. In this case, the second antenna 102 also needs to be grounded through a capacitor, that is, through the second capacitor 132. Furthermore, referring to Figure 8, when the first grounding position and the second grounding position are disconnected through a break, the first SAR sensor 104 will not include the frame area corresponding to the second antenna 102.

[0037] It is understood that there is a certain gap between the first grounding point 111 and the first frame 105 along the length direction of the first frame 105, so as to ensure that the first SAR sensor 104 can simultaneously cover the top frame and side frame of the electronic device.

[0038] The third antenna 103 may include only a portion of the second frame 106, or it may include both a portion of the second frame 106 and a portion of the third frame 107.

[0039] The fact that the first antenna 101 and the second antenna 102 operate in the first frequency band means that the first antenna 101 and the second antenna 102 can receive and transmit signals in the first frequency band. Similarly, the fact that the third antenna 103 operates in the second frequency band means that the third antenna 103 can receive and transmit signals in the second frequency band.

[0040] It is understandable that the specific values ​​of the first and second distances mentioned above can vary depending on the shape of the electronic device. The first distance is greater than the second distance, meaning that the second break 110 is closer to the top edge of the electronic device relative to the bottom edge.

[0041] In this embodiment, since the first SAR sensor 104 includes the frame area between the first break 109 and the first grounding point 111 in the conductive frame 100, the first SAR sensor 104 can be used to perform SAR detection on the first antenna 101 and also to perform SAR detection near the second antenna 102. When the first frame 105 is the top frame of the electronic device, the electronic device can reduce the SAR of the antenna in the area where a human is close by based on the detection results of the first SAR sensor. This helps to avoid the problem of reduced antenna power caused by the human being close by, thereby enabling the electronic device to have better antenna performance in free scenarios and vertical handheld scenarios in the first frequency band. Meanwhile, since the first frame 105 is the top frame of the electronic device, the distance between the second break 110 and the third frame 107 is greater than the distance between the second break 110 and the first frame 105. That is, the second break is closer to the top frame than the bottom frame of the electronic device. Thus, when the electronic device is in portrait mode, landscape mode, or head-and-hand call mode, it is difficult for the user to hold the second break 110. This helps the electronic device to have better antenna performance in portrait mode, landscape mode, and head-and-hand call scenarios in the second frequency band.

[0042] Optionally, the distance between the second break 110 and the third frame 107 is greater than or equal to 85 mm.

[0043] Specifically, please refer to Figure 2. When the electronic device is a mobile phone, during the Over-The-Air (OTA) test of the antenna head and hand simulation model, the distance between the thumb gripping position of the model hand and the bottom of the electronic device is 79mm. In actual use, the area within 85mm of the side frame to the bottom frame is easily gripped by the user. Therefore, if the antenna gap is set within 85mm of the side frame to the bottom frame, the risk of the antenna gap being gripped is high, which may lead to a reduction in antenna performance.

[0044] Therefore, when the electronic device is a mobile phone, by ensuring that the distance between the second break 110 and the third frame 107 is greater than or equal to 85mm, it can be ensured that the user cannot hold the phone in this mode. The head-and-hand mode refers to the mode in which the user holds the phone close to their head while making a call.

[0045] In some embodiments of this application, the distance between the second break 110 and the third frame 107 is greater than or equal to 100mm. This helps to further avoid the area where the second break 110 is located being blocked by a person's hand in various scenarios.

[0046] In this embodiment, by making the distance between the second break 110 and the third frame 107 greater than or equal to 85mm, it is difficult for a person to hold the second break 110 when the electronic device is in a free state, a portrait holding state, a landscape state, or a head-and-hand call state. This helps the electronic device to have better antenna performance in various scenarios in the second frequency band.

[0047] Optionally, the conductive frame 100 is further provided with a fourth antenna 113, which operates in the second frequency band. The fourth frame 108 is provided with a third break 114, and the fourth antenna 113 includes at least a portion of the frame area in the fourth frame 108 that extends from the third break 114 toward the side facing the third frame 107.

[0048] The distance between the third break 114 and the third frame 107 is the third distance, and the distance between the third break 114 and the first frame 105 is the fourth distance. The third distance is greater than the fourth distance, and the third distance is greater than or equal to 85mm.

[0049] It is understandable that the specific values ​​of the third and fourth distances mentioned above can vary depending on the shape of the electronic device. The third distance being greater than the fourth distance means that the third break 114 is closer to the top edge relative to the bottom edge of the electronic device.

[0050] In some embodiments of this application, the distance between the third break 114 and the third frame 107 is greater than or equal to 100mm. This helps to further avoid the area where the third break 114 is located being blocked by a person's hand in various scenarios.

[0051] Specifically, since the third antenna 103 and the fourth antenna 113 both have double-slit radiation and high free aperture efficiency, the electronic device can have good antenna performance in the free mode of the second frequency band.

[0052] In this embodiment, since the third distance is greater than the fourth distance, and the distance between the third break 114 and the third frame 107 is greater than or equal to 85mm, it is difficult for a person to hold the third break 114 when the electronic device is in a free state, a vertical screen holding state, a horizontal screen state, or a head-and-hand call state. In this way, while improving the low-frequency free index, it can help to further reduce the impact of hand holding on the low-frequency antenna.

[0053] Optionally, the first frame 105 is further provided with a fourth break 115, the fourth break 115 being located between the first break 109 and the fourth frame 108; the third frame 107 is provided with a fifth break 116 and a sixth break 117, the fifth break 116 being located between the sixth break 117 and the fourth frame 108; the fourth frame 108 is further provided with a seventh break 118, the seventh break 118 being located between the third break 114 and the first frame 105; the third frame 107 is provided with a third grounding point 119, the third grounding point 119 being located between the sixth break 117 and the second frame 106; the first frame 105 is provided with a fourth grounding point 120, the fourth grounding point 120 being located between the fourth break 115 and the fourth frame 108; the fourth frame 108 is provided with an eighth grounding point 138, the eighth grounding point 138 being located between the seventh break 118 and the first frame 105;

[0054] The conductive frame 100 is further provided with a fifth antenna 121, a sixth antenna 122 and a positioning antenna 123. The fifth antenna 121 and the sixth antenna 122 operate in the first frequency band. The fifth antenna 121 includes the frame area between the fifth break 116 and the third grounding point 119. The sixth antenna 122 includes the frame area between the third break 114 and the eighth grounding point 138. The positioning antenna 123 includes the frame area between the fourth break 115 and the fourth grounding position.

[0055] The fact that the fifth antenna 121 and the sixth antenna 122 operate in the first frequency band means that the fifth antenna 121 and the sixth antenna 122 can receive and transmit signals in the first frequency band. The positioning antenna 123 can correspond to various positioning antennas; for example, the positioning antenna 123 can correspond to a Global Positioning System (GPS) antenna, that is, the positioning antenna 123 can form a GPS antenna.

[0056] In this embodiment, by further configuring the fifth antenna 121 and the sixth antenna 122, since the first antenna 101, the second antenna 102, the fifth antenna 121 and the sixth antenna 122 all operate in the first frequency band, when communicating with signals in the first frequency band, the antenna with the best performance can be selected for communication according to the specific scenario, which is beneficial to further improve the performance of the antenna.

[0057] Optionally, the electronic device further includes at least one of the following:

[0058] The second SAR sensor 124 includes at least a portion of the frame region in the fourth frame 108 that extends from the third break 114 toward the side facing the third frame 107.

[0059] The third SAR sensor 125 includes a frame region between the fifth break 116 and the sixth break 117;

[0060] The fourth SAR sensor 126 includes a frame region between the first break 109 and the fourth break 115.

[0061] The first SAR sensor 104, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 described above can be various common SAR sensors. In some embodiments of this application, the structures of the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be the same as those of the first SAR sensor 104, differing only in the connected frame area to achieve SAR detection of different frame areas. Specifically, each of the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can include a SAR sensor IC, and the frame area included by each SAR sensor is connected to the corresponding SAR sensor IC. The frame area included by each SAR sensor can be grounded or not, depending on actual needs. When the frame area included by the SAR sensor needs to be grounded, it needs to be grounded through a capacitor. For example, please refer to Figure 14, which shows an embodiment where all SAR sensors are grounded through capacitors. Correspondingly, when the frame area included by the SAR sensor does not need to be grounded, the corresponding capacitor does not need to be provided.

[0062] In the aforementioned first SAR sensor 104, second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126, different SAR sensor chips can be connected to the frame regions of different SAR sensors. Furthermore, the first SAR sensor 104, second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126 can also reuse the same SAR sensor chip. Referring to Figure 14, in this embodiment, the first SAR sensor 104 includes a first sensing stub 1041 and a SAR sensor chip 1042; the second SAR sensor 124 includes a second sensing stub 1241 and a SAR sensor chip 1042; the third SAR sensor 125 includes a third sensing stub 1251 and a SAR sensor chip 1042; and the fourth SAR sensor 126 includes a fourth sensing stub 1261 and a SAR sensor chip 1042. The SAR sensor chip 1042 is a chip disposed inside an electronic device. The first sensing branch 1041, the second sensing branch 1241, the third sensing branch 1251, and the fourth sensing branch 1261 are different frame regions in the conductive frame 100. For example, in the embodiment shown in FIG3, the first sensing branch 1041 includes the frame region between HD segments, the second sensing branch 1241 includes the frame region between SU ​​segments, the third sensing branch 1251 includes the frame region between VW segments, and the fourth sensing branch 1261 includes the frame region between JI segments.

[0063] Alternatively, in the embodiment shown in FIG8, the first sensing branch 1041 includes a frame region between HD” segments, the second sensing branch 1241 includes a frame region between SU ​​segments, the third sensing branch 1251 includes a frame region between VW segments, and the fourth sensing branch 1261 includes a frame region between JI segments.

[0064] Alternatively, in the embodiment shown in FIG10, the first sensing branch 1041 includes a frame region between HD” segments, the second sensing branch 1241 includes a frame region between SU” segments, the third sensing branch 1251 includes a frame region between VW segments, and the fourth sensing branch 1261 includes a frame region between JI segments.

[0065] It should be noted that in specific implementations, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be selectively added based on cost, product price, market demand, and the necessity of OTA upgrades. For example, in some regions, setting only the first SAR sensor 104 is sufficient to ensure free movement of mid-to-high frequency (MHB), optimal handheld performance, and no degradation of bodySAR. For other regions, to ensure complete sensor coverage of the SAR hotspot of the top first antenna 101, both the first SAR sensor 104 and the fourth SAR sensor 126 need to be set simultaneously to achieve free movement of the first antenna 101, optimal handheld performance, and ensure no degradation of bodySAR in this scenario. For flagship models with high cost tolerance, adding the second SAR sensor 124 can be considered to further improve performance, which can further enhance the free movement and landscape performance of the fourth antenna 113.

[0066] In addition, in some embodiments, a third SAR sensor 125 can be added, and the OTA performance can be further optimized by combining different SAR sensor triggering logic and software algorithm to adjust the antenna switch configuration.

[0067] In this embodiment, by including at least one of the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 in the electronic device, it is beneficial to further optimize the antenna performance such as OTA of the antenna in the electronic device.

[0068] Optionally, the conductive frame 100 is provided with the second SAR sensor 124 and the third SAR sensor 125, and the electronic device is configured as follows:

[0069] When the second SAR sensor 124 and the third SAR sensor 125 are in the triggered state and the first SAR sensor 104 is in the non-triggered state, the signal of the first frequency band is transmitted based on the first antenna 101, and the signal of the first frequency band is received based on the second antenna 102, the fifth antenna 121 and the sixth antenna 122.

[0070] When the first SAR sensor 104 and the third SAR sensor 125 are in a triggered state and the second SAR sensor 124 is in a non-triggered state, the signal of the first frequency band is transmitted based on the sixth antenna 122, and the signal of the first frequency band is received based on the first antenna 101, the second antenna 102 and the fifth antenna 121.

[0071] When the first SAR sensor 104 and the second SAR sensor 124 are in a triggered state and the third SAR sensor 125 is in a non-triggered state, the signal of the first frequency band is transmitted based on the fifth antenna 121, and the signal of the first frequency band is received based on the second antenna 102, the fifth antenna 121 and the sixth antenna 122.

[0072] The first SAR sensor 104 is in a triggered state, meaning it detects a human body approaching the first antenna 101. Conversely, when it is in a non-triggered state, it does not detect a human body approaching the first antenna 101. The second SAR sensor 124 is in a triggered state, meaning it detects a human body approaching the fourth antenna 113. Conversely, when it is in a non-triggered state, it does not detect a human body approaching the fourth antenna 113. The third SAR sensor 125 is in a triggered state, meaning it detects a human body approaching the fifth antenna 121. Conversely, when it is in a non-triggered state, it does not detect a human body approaching the fifth antenna 121.

[0073] Thus, based on the trigger states of the first SAR sensor 104, the second SAR sensor 124, and the third SAR sensor 125, the antenna switch configuration can be adjusted through a software algorithm in the electronic device to further optimize OTA performance. If the electronic device is configured with a three-channel SAR sensor setup (first SAR sensor 104, second SAR sensor 124, and third SAR sensor 125), the software optimization algorithm can be as follows:

[0074] If the second SAR sensor 124 and the third SAR sensor 125 are triggered, but the first SAR sensor 104 is not triggered, then it is determined to be a portrait-oriented handheld scenario. The MHB transmitting antenna can be set in the first antenna 101, and the resonant efficiency of each band can be slightly biased towards transmission to improve transmission performance. The second antenna 102, the fifth antenna 121 and the sixth antenna 122 are set in a design that is slightly biased towards reception performance to achieve the best transmission and reception of MHB in the portrait-oriented scenario.

[0075] If the first SAR sensor 104 and the third SAR sensor 125 are triggered, but the second SAR sensor 124 is not triggered, then the scenario is determined to be a landscape handheld display. The MHB transmitting antenna can be further positioned on the sixth antenna 122, while the resonant efficiency of each band is slightly biased towards transmission to improve transmission performance. The first antenna 101, the second antenna 102, and the fifth antenna 121 are positioned with a slightly biased design towards reception performance to achieve optimal MHB transmission and reception performance in a portrait display scenario.

[0076] If the first SAR sensor 104 and the second SAR sensor 124 are triggered, but the third SAR sensor 125 is not triggered, it is determined to be a head-and-hand communication scenario. In this scenario, the hand is far from the bottom fifth antenna 121, causing the third SAR sensor 125 to not be triggered. In this case, the transmitting antenna corresponding to the fifth antenna 121 can be set to a non-bodySAR mode, thereby improving the head-and-hand communication performance of the fifth antenna 121. Furthermore, in certain specific appearances (such as 3D curved screens), the SAR of the sixth antenna 122 can meet the standard without power reduction, and the maximum direction of the bodySAR of the sixth antenna 122 is generally perpendicular to the edge and far from the head. In this case, the sixth antenna 122 also does not need to reduce bodySAR, thereby improving the head-and-hand communication transmission capability of the sixth antenna 122.

[0077] Please refer to Figure 1. The third SAR sensor 125 is located near the sub-board 130 of the electronic device, and the UV segment is adjacent to the USB interface 139 of the electronic device.

[0078] In this embodiment, the antenna switch configuration is adjusted using a software algorithm in the electronic device based on the trigger states of the first SAR sensor 104, the second SAR sensor 124, and the third SAR sensor 125, in order to further optimize OTA performance.

[0079] Please refer to Figure 1. Figure 1 shows a seven-slit electronic device provided in an embodiment of this application, whose specific structure has the following features:

[0080] SAR Sensor: The SAR sensor consists of a SARsensor IC and a corresponding housing area. The housing area corresponding to the SARsensor IC forms the sensor's inductor. The housing area corresponding to the SARsensor IC cannot be directly grounded; it can be grounded via a capacitor to ensure SAR sensor functionality. As shown in Figure 14, the first SAR sensor 104 is illustrated with a capacitor grounding diagram. In practice, when the second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126, which also function as SAR sensors, use multiplexed antenna radiators as SAR sensors, they all require capacitor grounding. Whether additional capacitors are needed depends on design requirements and is not specifically illustrated. In some embodiments of this application, the electronic device includes at least the first SAR sensor 104, which includes at least the top GH segment radiator and the right side portion of the side DG segment motherboard 129 radiator shown in Figure 1. To ensure that the first SAR sensor 104 can be used simultaneously for the top first antenna 101 (radiating through the first break 109) and the side second antenna 102 (radiating through the second break 110), the optimal transmission performance is achieved for both MHB FS and vertical handheld scenarios.

[0081] MHB free, manual transmission capability: achieved by the first antenna 101 radiating through the first slit 109.

[0082] MHB Head / Hand / Game Hand: The preferred method is through the sixth antenna 122. This can be achieved by the OP segment radiator radiating through the seventh break 118, or by the PR segment radiator radiating through the third break 114. Furthermore, when two or more antennas share the same power amplifier (PA) in an electronic device, antennas farther from the PA require longer PCB traces for connection, resulting in greater transmission loss. Therefore, to improve conduction performance, the number of PAs in the electronic device can be increased based on cost constraints. For example, a separate PA can be provided for each antenna, or only antennas that are close together can share the same PA, while antennas that are farther apart can have a separate PA, shortening the PCB trace length and thus reducing transmission loss. Alternatively, to further reduce transmission loss, the PCB traces connecting the antennas can be replaced with coaxial cables. Since the transmission loss of cables is less than that of PCB traces, replacing PCB traces with cables can also reduce transmission loss. The secondary option for MHB head-hand is achieved through the fifth antenna 121. The head SAR is basically not reduced when it is far from the head, and the head-hand is superior to the first antenna 101 and the second antenna 102.

[0083] Low-frequency freedom, human hand, head / hand / game hand: The low-frequency response of the entire device consists of two antennas with relatively small derating for low-frequency human hand, human head, and landscape game modes. The design features are as follows: ① The third antenna 103 is located on the right side of the motherboard 129, radiating through the second break 110 via an AC segment radiator. The distance from the second break 110 to the bottom of the electronic device (LS1) is no less than 85mm, and can be more than 100mm. See Figure 2 for a head / hand simulation model diagram. As shown in Figure 2, when LS1 is more than 100mm, the hand cannot reach the device in this mode. ② The other low-frequency antenna is located on the fourth antenna 113, which has two breaks. At least one of these breaks (the third break 114) is at least 85mm from the bottom of the electronic device (LS5), and can be more than 100mm (generally located above the power button). This improves low-frequency freedom while reducing the impact of hand grip. As shown in Figure 1, this antenna can be excited by the metal radiator SU between the third break 114 and the fifth break 116, radiating through the two breaks. This antenna features dual-slit radiation and high free-aperture efficiency. Both low-frequency antennas are positioned far from the head, resulting in less degradation when held in hand compared to existing technologies. Furthermore, both low-frequency antennas are difficult to hold in either horizontal or vertical orientations, achieving low-frequency performance that is suitable for all scenarios, including hand, head, and horizontal orientations.

[0084] Depending on cost, product price, market demand, and the necessity of OTA upgrades, the second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126 can be selectively added. For example, in some regions, setting only the first SAR sensor 104 is sufficient to ensure free-flowing mid-to-high frequency (MHB) signals, optimal handheld performance, and no degradation in body SAR. For other regions, to ensure complete sensor coverage of the SAR hotspot of the top first antenna 101, both the first SAR sensor 104 and the fourth SAR sensor 126 need to be set simultaneously to achieve free-flowing first antenna 101 signals, optimal handheld performance, and ensure no degradation in body SAR in this scenario. For flagship models with high cost tolerance, adding the second SAR sensor 124 can further improve performance, enhancing the free-flowing and landscape performance of the fourth antenna 113.

[0085] In addition, in some embodiments, a third SAR sensor 125 can be added, and the OTA performance can be further optimized by combining different SAR sensor triggering logic and software algorithm to adjust the antenna switch configuration.

[0086] Optionally, referring to Figure 3, the first frame 105 further includes a tenth grounding point 127, which is grounded and located between the first break 109 and the fourth break 115. The first antenna 101 also includes a frame area between the tenth grounding point 127 and the first break 109. The feed point of the first antenna 101 is located between the tenth grounding point 127 and the first break 109. The feed point of the positioning antenna corresponding to the positioning antenna 123 is located between the fourth grounding point 120 and the fourth break 115.

[0087] Please refer to Figure 1. The tenth grounding point 127 is located near the front-facing camera 128 of the electronic device. The tenth grounding point 127 can be directly grounded, or it can be grounded via a capacitor.

[0088] In this embodiment, to solve the problem of ground isolation between the HG portion radiator of the first antenna 101 and the second antenna 102, the intermediate frequency resonance of the first antenna 101 is achieved by exciting the top ZI segment radiator. Since the GPS frequency (1575MHz) is very close to the intermediate frequency B3 (1710-1880MHz), after ZI excitation of B3, the GPS antenna needs to be adjusted to be fed at F23 in Figure 3. The LK stub excitation achieves isolation between the GPS and the B3 mode of the first antenna 101. At the same time, it can also achieve isolation between the B3 mode of the first antenna 101 and the B3 (DF stub excitation) mode of the second antenna 102, thereby ensuring that the efficiency of the first antenna 101 and the GPS antenna can be well compatible.

[0089] Please refer to Figure 3. Figure 3 shows a seven-slit electronic device provided in an embodiment of this application, whose specific structure has the following features:

[0090] SAR Sensor: The SAR sensor consists of a SARsensor IC and its corresponding frame area. The frame area cannot be directly grounded; it can be grounded via a capacitor to ensure SAR sensor functionality. As shown in Figure 14, the first SAR sensor 104 is illustrated with a capacitor grounding diagram. In practice, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126, which also function as SAR sensors, all require capacitor grounding when using multiplexed antenna radiators. Whether additional capacitors are needed depends on design requirements and is not specifically illustrated. In some embodiments of this application, the electronic device includes at least the first SAR sensor 104, which includes at least the top GH segment radiator shown in Figure 3 and the right side portion of the side DG segment motherboard 129 radiator. This ensures that the first SAR sensor 104 can be simultaneously used for the top first antenna 101 (radiating through the first break 109) and the side second antenna 102 (radiating through the second break 110), achieving optimal transmission performance in both MHB FS and vertical handheld scenarios.

[0091] MHB free, manual transmission performance: achieved through the MHB position 1# antenna radiated by the first break 109. To solve the problem of ground isolation between the HG portion radiator of the first antenna 101 and the second antenna 102, this embodiment achieves the intermediate frequency resonance of the first antenna 101 by exciting the top ZI segment radiator. Since the GPS frequency (1575MHz) is very close to the intermediate frequency B3 (1710-1880MHz), after ZI excitation of B3, the GPS antenna needs to be adjusted to be fed at F23 in Figure 3. The LK stub excitation achieves isolation between GPS and the B3 mode of the first antenna 101. At the same time, it can also achieve isolation between the B3 mode of the first antenna 101 and the B3 (DF stub excitation) mode of the second antenna 102, thereby ensuring good compatibility of the efficiency of the first antenna 101, the second antenna 102, and the GPS antenna.

[0092] MHB head-and-hand / game hand: The preferred method is through the sixth antenna 122, which can be either an OP segment radiator radiating through the seventh break 118 or a PR segment radiator radiating through the third break 114. To improve conduction performance, the number of PAs in the electronic device can be increased according to the product's cost tolerance. In addition, to reduce transmission loss, the PCB traces connecting the antennas in the electronic device can be replaced with cable lines. The secondary option for MHB head-and-hand is through the fifth antenna 121. SAR degradation is minimal when the antenna is far from the head, and head-and-hand is superior to the first antenna 101 and the second antenna 102.

[0093] Low-frequency freedom, human hand, head / hand / game hand: The low-frequency response of the entire device consists of two antennas with relatively small derating for low-frequency human hand, head, and landscape game modes. The design features are as follows: ① The third antenna 103 is located on the right side of the motherboard 129, radiating through the second break 110 via an AC segment radiator. The distance from the second break 110 to the bottom of the electronic device (LS1) is no less than 85mm, and can be more than 100mm. See Figure 2 for a head / hand simulation model diagram. As shown in Figure 2, when LS1 is more than 100mm, the hand cannot reach the device in this mode. ② The other low-frequency antenna is located on the fourth antenna 113, which has two breaks. At least one of these breaks (the third break 114) is at least 85mm from the bottom of the electronic device (LS5), and can be more than 100mm (generally located above the power button). This improves low-frequency freedom while reducing the impact of hand grip. As shown in Figure 3, this antenna can be excited by the metal radiator SU between the third break 114 and the fifth break 116, radiating through the two breaks. This antenna features dual-slit radiation and high free-aperture efficiency. Both low-frequency antennas are positioned far from the head, resulting in less degradation when held in hand compared to existing technologies. Furthermore, both low-frequency antennas are difficult to hold in either horizontal or vertical orientations, achieving low-frequency performance that is suitable for all scenarios, including hand, head, and horizontal orientations.

[0094] Depending on cost, product price, market demand, and the necessity of OTA upgrades, the second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126 can be selectively added. For example, in some regions, setting only the first SAR sensor 104 is sufficient to ensure free-flowing mid-to-high frequency (MHB) signals, optimal handheld performance, and no degradation in body SAR. For other regions, to ensure complete sensor coverage of the SAR hotspot of the top first antenna 101, both the first SAR sensor 104 and the fourth SAR sensor 126 need to be set simultaneously to achieve free-flowing first antenna 101 signals, optimal handheld performance, and ensure no degradation in body SAR in this scenario. For flagship models with high cost tolerance, adding the second SAR sensor 124 can further improve performance, enhancing the free-flowing and landscape performance of the fourth antenna 113.

[0095] In addition, in some embodiments, a third SAR sensor 125 can be added, and the OTA performance can be further optimized by combining different SAR sensor triggering logic and software algorithm to adjust the antenna switch configuration.

[0096] Optionally, referring to Figure 5, the fourth frame 108 is further provided with an eighth break 133, which is located between the third break 114 and the third frame 107. The fourth frame 108 is also provided with a fifth grounding point 134, which is located between the eighth break 133 and the third frame 107. The third frame 107 also includes a sixth grounding point 135, which is located between the fifth break 116 and the fourth frame 108.

[0097] The fourth antenna 113 includes a frame region between the third break 114 and the fifth grounding point 134, and the frame region between the fifth break 116 and the sixth grounding point 135 is a parasitic branch of the fifth antenna 121.

[0098] The difference between this implementation and the embodiment shown in Figure 1 is that an eighth break 133 is added to the fourth frame 108.

[0099] Please refer to Figure 5. Figure 5 shows an electronic device with eight gaps provided in an embodiment of this application. Its specific structure has the following features:

[0100] SAR Sensor: The SAR sensor consists of a SARsensor IC and its corresponding frame area. The frame area cannot be directly grounded; it can be grounded via a capacitor to ensure SAR sensor functionality. As shown in Figure 14, the first SAR sensor 104 is illustrated with a capacitor grounding diagram. In practice, the second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126, which use multiplexed antenna radiators as SAR sensors, all require capacitor grounding. Whether to add capacitors depends on design requirements and is not specifically illustrated. In some embodiments of this application, the electronic device includes at least the first SAR sensor 104, which includes at least the top GH segment radiator and the right side portion of the side DG segment motherboard 129 radiator shown in Figure 5. This ensures that the first SAR sensor 104 can be used simultaneously for the top first antenna 101 (radiating through the first break 109) and the side second antenna 102 (radiating through the second break 110), achieving optimal transmission performance in both MHB FS and vertical handheld scenarios.

[0101] MHB free, manual transmission performance: achieved through the MHB position 1# antenna radiated by the first break 109. To solve the problem of ground isolation between the HG portion radiator of the first antenna 101 and the second antenna 102, this embodiment achieves the intermediate frequency resonance of the first antenna 101 by exciting the top ZI segment radiator. Since the GPS frequency (1575MHz) is very close to the intermediate frequency B3 (1710-1880MHz), after ZI excitation of B3, the GPS antenna needs to be adjusted to be fed at F23 in Figure 5. The LK stub excitation achieves isolation between GPS and the B3 mode of the first antenna 101. At the same time, it can also achieve isolation between the B3 mode of the first antenna 101 and the B3 (DF stub excitation) mode of the second antenna 102, thereby ensuring good compatibility of the efficiency of the first antenna 101, the second antenna 102, and the GPS antenna.

[0102] MHB head-and-hand / game hand: The preferred method is through the sixth antenna 122, which can be either an OP segment radiator radiating through the seventh break 118 or a PR segment radiator radiating through the third break 114. To improve conduction performance, the number of PAs in the electronic device can be increased according to the product's cost tolerance. In addition, to reduce transmission loss, the PCB traces connecting the antennas in the electronic device can be replaced with cable lines. The secondary option for MHB head-and-hand is through the fifth antenna 121. SAR degradation is minimal when the antenna is far from the head, and head-and-hand is superior to the first antenna 101 and the second antenna 102.

[0103] Low-frequency freedom, human hand, head / hand / game hand: The low-frequency response of the entire device consists of two antennas with relatively small derating for human hand, head, and landscape gaming. The design features are as follows: ① The third antenna 103 is located on the right side of the motherboard 129, radiating from the AC segment radiator through the second break 110. The distance from the second break 110 to the bottom of the electronic device (LS1) is no less than 85mm, and can be more than 100mm. See Figure 2 for a head / hand simulation model. As shown in Figure 2, when LS1 is more than 100mm, the hand cannot reach the device in this mode. ② The other low-frequency antenna is located on the fourth antenna 113, which has two breaks. At least one of these breaks (the third break 114) is located at least 85mm from the bottom of the electronic device (LS5), and can be more than 100mm (generally located above the power button). This improves low-frequency freedom while reducing the impact of hand grip. By adding an eighth slit 133 in the fourth frame 108, the fourth antenna 113 is jointly excited by the SU” stub and the grounded U'T, and radiates through the third slit 114 and the eighth slit 133. This antenna has double-slit radiation and high free-aperture efficiency. Both low-frequency antennas are far from the head, resulting in less derating when held in hand compared to existing technologies. Furthermore, both low-frequency antennas cannot be held in either horizontal or reverse orientation, achieving low-frequency performance that is suitable for all scenarios, including hand, head, and horizontal orientation.

[0104] Depending on cost, product price, market demand, and the necessity of OTA upgrades, the second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126 can be selectively added. For example, in some regions, setting only the first SAR sensor 104 is sufficient to ensure free-flowing mid-to-high frequency (MHB) signals, optimal handheld performance, and no degradation in body SAR. For other regions, to ensure complete sensor coverage of the SAR hotspot of the top first antenna 101, both the first SAR sensor 104 and the fourth SAR sensor 126 need to be set simultaneously to achieve free-flowing first antenna 101 signals, optimal handheld performance, and ensure no degradation in body SAR in this scenario. For flagship models with high cost tolerance, adding the second SAR sensor 124 can further improve performance, enhancing the free-flowing and landscape performance of the fourth antenna 113.

[0105] In addition, in some embodiments, a third SAR sensor 125 can be added, and the OTA performance can be further optimized by combining different SAR sensor triggering logic and software algorithm to adjust the antenna switch configuration.

[0106] In this embodiment, by providing eight breaks in the conductive frame 100, the electronic device can have good antenna performance in both mid-to-high frequency and low frequency.

[0107] Optionally, referring to Figure 7, in some embodiments of this application, the second frame 106 is further provided with a ninth break 136, which is located between the first grounding point 111 and the second grounding point 112. In this case, the first SAR sensor 104 also includes the frame area between the first grounding point 111 and the ninth break 136, that is, the first SAR sensor 104 can also be used to perform SAR detection on the frame area between the first grounding point 111 and the ninth break 136.

[0108] Please refer to Figures 1 and 3. In some other embodiments of this application, the first grounding point 111 and the second grounding point 112 are connected by a frame. The first SAR sensor 104 also includes the frame area between the first grounding point 111 and the second break 110. That is, the first SAR sensor 104 can also be used to perform SAR detection on the frame area between the first grounding point 111 and the second break 110.

[0109] Please refer to Figures 1 and 3, which are schematic diagrams showing the direct connection between the first grounding point 111 and the second grounding point 112 through the frame. Please refer to Figure 7, which differs from the embodiment shown in Figure 1 in that a ninth break 136 is added between the first grounding point 111 and the second grounding point 112.

[0110] Please refer to Figure 7. Figure 7 shows an electronic device with eight gaps provided in an embodiment of this application. Its specific structure has the following features:

[0111] By setting the ninth break 136, there is no common radiator mutual coupling problem between the second antenna 102 and the first antenna 101. In this way, the first antenna 101 can flexibly use the ZI band or GH band to excite the intermediate frequency. The design restrictions on the GPS / Wireless Fidelity (wifi) / L5 antennas on both sides of the fourth break 115 are low. The extra ninth break 136 can be split up to design other antennas such as L5 / N78 / wifi. While doing a good job of LMH, the performance of L5 / wifi / sub6G antennas can be further improved.

[0112] SAR Sensor: The SAR sensor consists of a SARsensor IC and a metal conductor. The metal conductor cannot be directly grounded; it can be grounded via a capacitor to ensure SAR sensor functionality. In some embodiments of this application, the electronic device includes at least a first SAR sensor 104. The first SAR sensor 104 includes at least the top GH segment radiator shown in Figure 7 and the right side portion of the side GD segment motherboard 129 radiator. This ensures that the first SAR sensor 104 can be used simultaneously for SAR detection by the top first antenna 101 (radiating through the first break 109) and the side second antenna 102 (radiating through the second break 110).

[0113] MHB free, manual transmission performance: achieved through the first antenna 101 radiating from the first break 109. The first antenna 101 can flexibly adopt ZI or GH band excitation intermediate frequency according to the GPS Wi-Fi antenna design of the fourth break 115.

[0114] MHB head / hand / game hand: The preferred method is through the sixth antenna 122. This can be achieved by the OP segment radiator radiating through the seventh break 118, or by the PR segment radiator radiating through the third break 114. Specifically, for the second antenna 102, when the current in the mid-to-high frequency mode is strongest at point D and weakest at point D', the head SAR is lower than that of the antenna corresponding to the OP segment. In this case, the second antenna 102 can still achieve head / hand performance comparable to that of the antenna corresponding to the OP segment. That is, in this scenario, mid-to-high frequency head / hand performance can also be achieved through the second antenna 102. It should be noted that when achieving mid-to-high frequency head / hand performance based on the second antenna 102, the distance between the feed point E of the second antenna 102 and the first frame 105 is greater than the distance between the second ground point 112 and the first frame 105. To improve conduction performance, the number of PAs in the electronic device can be increased according to the product's cost tolerance. Furthermore, to reduce transmission loss, the PCB traces connecting the antenna in the electronic device can be replaced with cable lines. The secondary option for MHB head-hand is achieved through the fifth antenna 121. The head SAR is basically not reduced when it is far from the head, and the head-hand is superior to the first antenna 101 and the second antenna 102.

[0115] Low-frequency freedom, human hand, head / hand / game hand: The low-frequency response of the entire device consists of two antennas with relatively small derating for human hand, head, and landscape game modes. The design features are as follows: ① The third antenna 103 is located on the right side of the motherboard 129, radiating through the second break 110 via an AC segment radiator. The distance from the second break 110 to the bottom of the electronic device (LS1) is no less than 85mm, and can be more than 100mm. See Figure 2 for a head / hand simulation model diagram. As shown in Figure 2, when LS1 is more than 100mm, the hand cannot reach the device in this mode. ② The other low-frequency antenna is located on the fourth antenna 113, which has two breaks. At least one of these breaks (the third break 114) is at least 85mm from the bottom of the electronic device (LS5), and can be more than 100mm (generally located above the power button). This improves low-frequency freedom while reducing the impact of hand grip. As shown in Figure 7, this antenna can be excited by the metal radiator SU between the third break 114 and the fifth break 116, radiating through the two breaks. This antenna features dual-slit radiation and high free-aperture efficiency. Both low-frequency antennas are positioned far from the head, resulting in less degradation when held in hand compared to existing technologies. Furthermore, both low-frequency antennas are difficult to hold in either horizontal or vertical orientations, achieving low-frequency performance that is suitable for all scenarios, including hand, head, and horizontal orientations.

[0116] Depending on cost, product price, market demand, and the necessity of OTA upgrades, the second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126 can be selectively added. For example, in some regions, setting only the first SAR sensor 104 is sufficient to ensure free-flowing mid-to-high frequency (MHB) signals, optimal handheld performance, and no degradation in body SAR. For other regions, to ensure complete sensor coverage of the SAR hotspot of the top first antenna 101, both the first SAR sensor 104 and the fourth SAR sensor 126 need to be set simultaneously to achieve free-flowing first antenna 101 signals, optimal handheld performance, and ensure no degradation in body SAR in this scenario. For flagship models with high cost tolerance, adding the second SAR sensor 124 can further improve performance, enhancing the free-flowing and landscape performance of the fourth antenna 113.

[0117] In addition, in some embodiments, a third SAR sensor 125 can be added, and the OTA performance can be further optimized by combining different SAR sensor triggering logic and software algorithm to adjust the antenna switch configuration.

[0118] In this embodiment, by providing eight breaks in the conductive frame 100, the electronic device can have good antenna performance in both mid-to-high frequency and low frequency.

[0119] Optionally, referring to Figure 9, the fourth frame 108 also has an eighth break 133, which is located between the third break 114 and the third frame 107. The fourth frame 108 also has a fifth grounding point 134, which is located between the eighth break 133 and the third frame 107. The third frame 107 also includes a sixth grounding point 135, which is located between the fifth break 116 and the fourth frame 108. The third antenna 103 includes a frame area between the third break 114 and the fifth grounding point 134, and the fifth antenna 121 also includes a frame area between the fifth break 116 and the sixth grounding point 135.

[0120] The second frame 106 also has a ninth break 136, which is located between the first grounding point 111 and the second grounding point 112. The first SAR sensor 104 also includes a frame area between the first grounding point 111 and the ninth break 136.

[0121] The difference between this implementation and the embodiment shown in FIG1 is that an eighth break 133 is added in the fourth frame 108, and a ninth break 136 is added between the first grounding point 111 and the second grounding point 112.

[0122] Please refer to Figure 9. Figure 9 shows an electronic device with nine gaps provided in an embodiment of this application. Its specific structure has the following features:

[0123] By setting the ninth break 136, there is no common radiator mutual coupling problem between the second antenna 102 and the first antenna 101. In this way, the first antenna 101 can flexibly use the ZI band or GH band to excite the intermediate frequency. The design restrictions on the GPS / wifi / L5 antennas on both sides of the fourth break 115 are low. The extra ninth break 136 can be split up to design other antennas such as L5 / N78 / wifi. While doing a good job of LMH, the performance of L5 / wifi / sub6G antennas can be further improved.

[0124] SAR Sensor: The SAR sensor consists of a SARsensor IC and a metal conductor. The metal conductor cannot be directly grounded; it can be grounded via a capacitor to ensure SAR sensor functionality. In some embodiments of this application, the electronic device includes at least a first SAR sensor 104. The first SAR sensor 104 includes at least the top GH segment radiator and the right side portion of the side GD segment motherboard 129 radiator shown in Figure 9. This ensures that the first SAR sensor 104 can be used simultaneously for SAR detection by the top first antenna 101 (radiating through the first break 109) and the side second antenna 102 (radiating through the second break 110).

[0125] MHB free, manual transmission performance: achieved through the first antenna 101 radiating from the first break 109. The first antenna 101 can flexibly adopt ZI or GH band excitation intermediate frequency according to the GPS Wi-Fi antenna design of the fourth break 115.

[0126] MHB head / hand / game hand: The preferred method is through the sixth antenna 122. This can be achieved by the OP segment radiator radiating through the seventh break 118, or by the PR segment radiator radiating through the third break 114. Specifically, for the second antenna 102, when the current in the mid-to-high frequency mode is strongest at point D and weakest at point D', the head SAR is lower than that of the antenna corresponding to the OP segment. In this case, the second antenna 102 can still achieve head / hand performance comparable to that of the antenna corresponding to the OP segment. That is, in this scenario, mid-to-high frequency head / hand performance can also be achieved through the second antenna 102. It should be noted that when achieving mid-to-high frequency head / hand performance based on the second antenna 102, the distance between the feed point E of the second antenna 102 and the first frame 105 is greater than the distance between the second ground point 112 and the first frame 105. To improve conduction performance, the number of PAs in the electronic device can be increased according to the product's cost tolerance. Furthermore, to reduce transmission loss, the PCB traces connecting the antenna in the electronic device can be replaced with cable lines. The secondary option for MHB head-hand is achieved through the fifth antenna 121. The head SAR is basically not reduced when it is far from the head, and the head-hand is superior to the first antenna 101 and the second antenna 102.

[0127] Low-frequency freedom, human hand, head / hand / game hand: The low-frequency response of the entire device consists of two antennas with relatively small derating for human hand, head, and landscape gaming. The design features are as follows: ① The third antenna 103 is located on the right side of the motherboard 129, radiating from the AC segment radiator through the second break 110. The distance from the second break 110 to the bottom of the electronic device (LS1) is no less than 85mm, and can be more than 100mm. See Figure 2 for a head / hand simulation model. As shown in Figure 2, when LS1 is more than 100mm, the hand cannot reach the device in this mode. ② The other low-frequency antenna is located on the fourth antenna 113, which has two breaks. At least one of these breaks (the third break 114) is located at least 85mm from the bottom of the electronic device (LS5), and can be more than 100mm (generally located above the power button). This improves low-frequency freedom while reducing the impact of hand grip. By adding an eighth slit 133 in the fourth frame 108, the fourth antenna 113 is jointly excited by the SU” stub and the grounded U'T, and radiates through the third slit 114 and the eighth slit 133. This antenna has double-slit radiation and high free-aperture efficiency. Both low-frequency antennas are far from the head, resulting in less derating when held in hand compared to existing technologies. Furthermore, both low-frequency antennas cannot be held in either horizontal or reverse orientation, achieving low-frequency performance that is suitable for all scenarios, including hand, head, and horizontal orientation.

[0128] Depending on cost, product price, market demand, and the necessity of OTA upgrades, the second SAR sensor 124, third SAR sensor 125, and fourth SAR sensor 126 can be selectively added. For example, in some regions, setting only the first SAR sensor 104 is sufficient to ensure free-flowing mid-to-high frequency (MHB) signals, optimal handheld performance, and no degradation in body SAR. For other regions, to ensure complete sensor coverage of the SAR hotspot of the top first antenna 101, both the first SAR sensor 104 and the fourth SAR sensor 126 need to be set simultaneously to achieve free-flowing first antenna 101 signals, optimal handheld performance, and ensure no degradation in body SAR in this scenario. For flagship models with high cost tolerance, adding the second SAR sensor 124 can further improve performance, enhancing the free-flowing and landscape performance of the fourth antenna 113.

[0129] In addition, in some embodiments, a third SAR sensor 125 can be added, and the OTA performance can be further optimized by combining different SAR sensor triggering logic and software algorithm to adjust the antenna switch configuration.

[0130] In this embodiment, by setting nine breaks in the conductive frame 100, the electronic device can have good antenna performance in both mid-to-high frequency and low frequency.

[0131] Optionally, the fourth frame 108 is further provided with a seventh grounding point 137, which is located between the third break 114 and the seventh break 118;

[0132] The feed point of the sixth antenna 122 is located between the seventh grounding point 137 and the third break 114; or, the feed point of the sixth antenna 122 is located between the seventh grounding point 137 and the seventh break 118; or, the feed point of the sixth antenna 122 is located between the eighth grounding point 138 and the seventh break 118.

[0133] Please refer to Figure 4, which is a schematic diagram of the structure of an electronic device provided in some embodiments of this application. The difference between the embodiment shown in Figure 4 and the embodiment shown in Figure 3 is that the sixth antenna 122 is mainly excited by the MN segment, with a strong current located near point M, resulting in a higher head SAR and inferior head-hand performance compared to the embodiment shown in Figure 3. If the head-hand performance of the fifth antenna 121 is comparable to that of the sixth antenna 122 in the embodiment shown in Figure 3, the overall performance can also be comparable.

[0134] Please refer to Figure 6, which is a schematic diagram of the structure of an electronic device provided in some embodiments of this application. The difference between the embodiment shown in Figure 6 and the embodiment shown in Figure 5 is that the sixth antenna 122 is mainly excited by the MN segment, with a strong current located near point M, resulting in a higher head SAR and inferior head-hand performance compared to the embodiment shown in Figure 5. If the head-hand performance of the fifth antenna 121 is comparable to that of the sixth antenna 122 in the embodiment shown in Figure 5, the overall performance can also be comparable.

[0135] Please refer to Figure 8, which is a schematic diagram of the structure of an electronic device provided in some embodiments of this application. The difference between the embodiment shown in Figure 8 and the embodiment shown in Figure 7 is that the sixth antenna 122 is mainly excited by the MN segment, with a strong current located near point M, resulting in a higher head SAR and inferior head-hand performance compared to the embodiment shown in Figure 7. If the head-hand performance of the fifth antenna 121 is comparable to that of the sixth antenna 122 in the embodiment shown in Figure 7, the overall performance can also be comparable.

[0136] Please refer to Figure 10, which is a schematic diagram of the structure of an electronic device provided in some embodiments of this application. The difference between the embodiment shown in Figure 10 and the embodiment shown in Figure 9 is that the sixth antenna 122 is mainly excited by the MN segment, with a strong current located near point M, resulting in a higher head SAR and inferior head-hand performance compared to the embodiment shown in Figure 9. If the head-hand performance of the fifth antenna 121 is comparable to that of the sixth antenna 122 in the embodiment shown in Figure 9, the overall performance can also be comparable.

[0137] In this embodiment, by optimizing the antenna structure in the conductive frame 100, the electronic device can have good antenna performance in both mid-to-high frequency and low frequency.

[0138] Optionally, the second frame 106 further includes a ninth grounding point 143, which is located between the second break 110 and the third frame 107, and the third antenna 103 includes the frame area between the second break 110 and the ninth grounding point 143; or,

[0139] The third antenna 103 includes the frame region between the second break 110 and the third grounding point 119.

[0140] In practical applications, the fourth antenna 113 in the embodiments shown in Figure 3 and Figure 5 will reduce the effective width of the battery in the X direction, thus reducing the overall battery capacity. In the embodiments shown in Figure 3 and Figure 5, the second frame 106 also has a ninth grounding point 143, which is located between the second break 110 and the third frame 107. The third antenna 103 includes the frame area between the second break 110 and the ninth grounding point 143.

[0141] To further improve low-frequency performance, if battery capacity allows, the antenna scheme of the third antenna 103 can be mirrored and replaced by the fourth antenna 113 scheme shown in the embodiments of Figure 3 and Figure 5, which can further improve the overall low-frequency performance. For example, referring to Figure 11, the third antenna 103 includes the frame area between the second break 110 and the sixth break 117, that is, the third antenna 103 extends from the second break 110 to the sixth break 117. In this case, the third grounding point 119 in the above embodiment can be cancelled, or the third grounding point 119 can be grounded through the second switch 141 to achieve switching and tuning of more frequency bands. Referring to Figure 11, the part of the third antenna 103 located in the second frame 106 can be grounded through the first switch 140. When the third antenna 103 is in the working state, the first switch 140 can be in the on state or in the off state. Specifically, the tuning of the third antenna 103 can be achieved by controlling the first switch 140 to be on or off. Furthermore, referring to Figure 11, the second electronic device may also include a second switch 141 and a fourth switch 144, wherein the fourth switch 144 can tune the fifth antenna 121. The second switch 141 may include a first input terminal, a second input terminal, and an output terminal. The first input terminal is connected to the third grounding point 119, the second input terminal is connected to the VW stub, and the output terminal is grounded. The second switch 141 can simultaneously tune the fifth antenna 121 and the third antenna 103, and the number of paths at the first input terminal and the second input terminal can be changed as needed. Thus, when the electronic device operates in the second frequency band, the aperture efficiency of the third antenna 103 can be further increased by simultaneously tuning the CX frame stub and the VW frame stub through the first switch 140 and the second switch 141. In the embodiment shown in Figure 11, the feed point of the fifth antenna 121 is located at the UZ' stub, and at this time, the fourth switch 144 is connected to the feed point of the fifth antenna 121.

[0142] Please refer further to Figure 11. In the embodiment shown in Figure 11, the feed point of the fifth antenna 121 is located in the frame area between the fifth break 116 and the sixth grounding point 135.

[0143] Please refer to Figure 12, which is a schematic diagram of the structure of an electronic device provided in some other embodiments of this application. The difference between the embodiment shown in Figure 12 and the embodiment shown in Figure 11 is that the second switch 141 in the embodiment shown in Figure 12 includes only one input terminal, and the third grounding point 119 is grounded through the second switch 141. In addition, in the embodiment shown in Figure 12, the feed point of the fifth antenna 121 is located in the VW stub, near the sixth break 117. At the same time, a fifth switch 145 is added, and the UZ' stub is grounded through the fifth switch 145.

[0144] Please refer to Figure 13, which is a schematic diagram of the structure of an electronic device provided in some other embodiments of this application. The difference between the embodiment shown in Figure 13 and the embodiment shown in Figure 12 is that the embodiment shown in Figure 13 omits the fifth grounding point 134 and adds a third switch 142. The sixth grounding point 135 is grounded through the third switch 142.
