[0002] The present application claims priority to Chinese Patent Application No. 202410691275.8, filed on May 30, 2024, the contents of which are incorporated herein by reference in its entirety. TECHNICAL FIELD

[0003] The present application relates to the technical field of electronic products, in particular to an electronic device. BACKGROUND

[0004] Communication is a basic function of electronic products. In recent years, electronic products in the related technology have made great investment and improvement in communication capability. For example, radio frequency enhancement chips, homing antennas, and universal signal amplifiers, etc. improve the performance of electronic products in free, vertical handheld, horizontal screen game, and head-to-hand call scenarios from the aspects of hardware capability, antenna scheme, software algorithm, etc. to meet the signal experience needs of users in extreme weak signal scenarios. On the other hand, the new national standard has controlled the body specific absorption rate (body SAR) of electronic products. Compared with the past, the total radiated power (TRP) of some frequency bands will decrease by 1-3db on the basis of meeting the body SAR requirements, which poses a great challenge to antenna workers. Based on this, in the related technology, it is difficult for some electronic products to ensure that all antenna frequency bands have good antenna performance in various extreme scenarios. SUMMARY

[0005] The present application provides an electronic device, which can be beneficial to improve the antenna performance of the antenna in each frequency band.

[0006] In a first aspect, the present application provides an electronic device, comprising a conductive frame body and a first SAR sensor, the conductive frame body is provided with a first antenna, a second antenna and a third antenna, the first antenna and the second antenna respectively work in a first frequency band, the third antenna works 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 body comprises a first bezel, a second bezel, a third bezel and a fourth bezel connected in sequence, the first bezel is opposite to the third bezel, the second bezel is opposite to the fourth bezel, and the length of the first bezel is less than the length of the second bezel;

[0007] The first edge frame is provided with a first breakage, the second edge frame is provided with a second breakage, and the second edge frame is provided with a first grounding point and a second grounding point. The first grounding point and the second grounding point are located between the first breakage and the second breakage, and the second grounding point is located between the first grounding point and the second breakage. The first antenna includes a frame area between the first breakage and the first grounding point. The second antenna includes a frame area between the second grounding point and the second breakage. The third antenna includes at least part of the frame area in the second edge frame extending from the second breakage to the side of the third edge frame.

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

[0009] In the embodiment of the present application, since the first SAR sensor includes a frame area between the first breakage and the first grounding point in the conductive frame, the first SAR sensor can be used for SAR detection of the first antenna and SAR detection of the vicinity of the second antenna. When the first edge frame is the top edge frame of the electronic device, the electronic device can perform SAR reduction processing on the antenna of the area close to the human body according to the detection result of the first SAR sensor, which is beneficial to avoid the problem of power reduction of the antenna caused by the proximity of the human body, thereby facilitating the electronic device to have good antenna performance in the free scene and the vertical screen handheld scene of the first frequency band. At the same time, since the first edge frame is the top edge frame of the electronic device, the distance between the second breakage and the third edge frame is greater than the distance between the second breakage and the first edge frame, that is, the second breakage is closer to the top edge frame relative to the bottom edge frame of the electronic device. Therefore, in the vertical screen holding state, the horizontal screen state, the head-hand calling state and other states of the electronic device, it is difficult for the human hand to hold the second breakage, thereby facilitating the electronic device to have good antenna performance in the vertical screen, horizontal screen holding, head-hand calling and other scenes of the second frequency band.

[0024] The technical solutions in the embodiments of the present application will be described clearly below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art belong to the scope of protection of the present application.

[0025] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than that illustrated or described herein, and the objects distinguished by "first", "second", etc. are generally a category, and do not limit the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0026] The electronic device provided by the embodiments of the present application will be described in detail below in combination with the drawings, specific embodiments and application scenarios thereof.

[0027] Please refer to FIG. 1, the electronic device provided by the embodiments of the present application 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 respectively work at a first frequency band, the third antenna 103 works at 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 bezel 105, a second bezel 106, a third bezel 107 and a fourth bezel 108 connected in sequence, the first bezel 105 is opposite to the third bezel 107, the second bezel 106 is opposite to the fourth bezel 108, and the length of the first bezel 105 is less than the length of the second bezel 106;

[0028] The first bezel 105 is provided with a first break 109, the second bezel 106 is provided with a second break 110, and the second bezel 106 is provided with 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 the frame area between the first break 109 and the first grounding point 111; the second antenna 102 includes the frame area between the second grounding point 112 and the second break 110; the third antenna 103 includes at least part of the frame area in the second bezel 106 extending from the second break 110 to the side of the third bezel 107;

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

[0030] The conductive frame 100 described above can be a metal middle frame of an electronic device. The electronic device described above can be various handheld terminals with communication functions, for example, a mobile phone, a tablet computer, etc.

[0031] The first frequency band can be a middle high band (MHB) frequency band, and the second frequency band can be a lower band (LB) frequency band. For example, the first frequency band can range from 1710 MHz to 2690 MHz, and the second frequency band can range from 617 MHz to 960 MHz.

[0032] The first SAR sensor 104 can further include a SAR sensor integrated circuit (SAR sensor IC), which can be electrically connected to any position in the frame area between the first break 109 and the first grounding point 111 to form the first SAR sensor 104. In addition, when the first SAR sensor 104 needs to be grounded, it needs to be grounded through the first capacitor 131 shown in FIG. 1.

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

[0034] Referring to FIG. 1, the first frame 105 is the frame at the top of the electronic device, the third frame 107 is the frame at the bottom of the electronic device, the second frame 106 is the right frame in the back cover direction view of the electronic device, and the fourth frame 108 is the left frame in the back cover direction view of the electronic device.

[0035] It can be understood that the excitation positions corresponding to the respective antennas can be set according to actual needs.

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

[0037] It can be understood that in the length direction of the first frame 105, the first grounding point 111 and the first frame 105 have a certain gap, so that the first SAR sensor 104 can cover the top frame and the side frame of the electronic device at the same time.

[0038] The third antenna 103 can include only a partial area of the second bezel 106, or can include a partial area of the second bezel 106 and a partial area of the third bezel 107.

[0039] The first antenna 101 and the second antenna 102 operating in the first frequency band can mean that the first antenna 101 and the second antenna 102 can receive and transmit signals in the first frequency band. The third antenna 103 operating in the second frequency band can mean that the third antenna 103 can receive and transmit signals in the second frequency band.

[0040] It can be understood that the specific values of the first distance and the second distance can change according to changes in the form of the electronic device. The first distance is greater than the second distance, that is, the second break 110 is closer to the top bezel than to the bottom bezel of the electronic device.

[0041] In this embodiment, since the first SAR sensor 104 includes the frame area between the first break 109 and the first ground point 111 in the conductive frame 100, the first SAR sensor 104 can be used for SAR detection of the first antenna 101 and SAR detection of the vicinity of the second antenna 102. When the first bezel 105 is the top bezel of the electronic device, the electronic device can perform SAR reduction processing on the antenna in the area close to the human body according to the detection result of the first SAR sensor, which is beneficial to avoid the problem of power reduction of the antenna caused by the proximity of the human body, thereby facilitating the electronic device to have good antenna performance in the free scene and the vertical screen handheld scene in the first frequency band. At the same time, since the first bezel 105 is the top bezel of the electronic device, the distance between the second break 110 and the third bezel 107 is greater than the distance between the second break 110 and the first bezel 105, that is, the second break is closer to the top bezel than to the bottom bezel of the electronic device. In this way, in the vertical screen holding state, the horizontal screen state, the head-to-hand call state, and the like of the electronic device, it is difficult for the human hand to hold the second break 110, thereby facilitating the electronic device to have good antenna performance in the vertical screen, horizontal screen holding, head-to-hand call, and the like in the second frequency band.

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

[0043] Specifically, please refer to FIG. 2, when the electronic device is a mobile phone, in the process of Over-The-Air (OTA) test on the antenna head hand simulation model, the distance between the position where the model hand holds the big thumb and the bottom of the electronic device is 79mm, in the actual use process, the side frame within the range of 85mm from the bottom frame is easy to be held by the user, therefore, if the antenna gap is arranged within the range of 85mm from the bottom frame of the side frame, the antenna gap is at a higher risk of being held, and thus the antenna performance can be reduced.

[0044] Based on this, when the electronic device is a mobile phone, by making the distance between the second gap 110 and the third frame 107 greater than or equal to 85mm, it can be ensured that the hand cannot hold in this mode. Wherein, the head hand mode is a mode in which the user holds the mobile phone close to the head to talk.

[0045] In some embodiments of the present application, the distance between the second gap 110 and the third frame 107 is greater than or equal to 100mm, thus, it is beneficial to further avoid the hand from shielding the area where the second gap 110 is located in various scenarios.

[0046] In this implementation, by making the distance between the second gap 110 and the third frame 107 greater than or equal to 85mm, thus, in the free state, the vertical screen holding state, the horizontal screen state, the head hand calling state and other states of the electronic device, the hand is difficult to hold the second gap 110, thus, it is beneficial to make the electronic device have good antenna performance in various scenarios of the second frequency band.

[0047] Optionally, the conductive frame 100 is further provided with a fourth antenna 113, the fourth antenna 113 works in the second frequency band, the fourth frame 108 is provided with a third gap 114, the fourth antenna 113 includes at least part of the frame area in the fourth frame 108 extending from the third gap 114 to the side of the third frame 107;

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

[0049] It can be understood that the specific values of the above-mentioned third distance and the fourth distance can change according to the change of the form of the electronic device. The third distance is greater than the fourth distance, that is, the third gap 114 is closer to the top frame relative to the bottom frame of the electronic device.

[0050] In some embodiments of the present application, the distance between the third break 114 and the third frame 107 is greater than or equal to 100 mm, so as to further avoid the human hand from shielding the area where the third break 114 is located in various scenarios.

[0051] Specifically, since the third antenna 103 and the fourth antenna 113 both have double-break radiation, the free aperture efficiency is high, so that the electronic device has better 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 85 mm, it is difficult for the human hand to hold the third break 114 in the free state, the vertical screen holding state, the horizontal screen state, the head-to-hand call state, and other states of the electronic device, so as to improve the low-frequency free index while further reducing the influence 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 is 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 is 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 is 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 is 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 is 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 is 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 respectively 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 fifth antenna 121 and the sixth antenna 122 can receive and transmit signals of the first frequency band.

[0056] In this embodiment, the fifth antenna 121 and the sixth antenna 122 are further arranged, and the first antenna 101, the second antenna 102, the fifth antenna 121 and the sixth antenna 122 all work in the first frequency band. Thus, when signals of the first frequency band are communicated, the antenna with the best performance can be selected according to a specific scene, 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 part of the frame area in the fourth frame 108 extending from the third break 114 to the side of the third frame 107;

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

[0060] The fourth SAR sensor 126 includes the frame area 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 can be various common SAR sensors. In some embodiments of the present application, the structures of the second SAR sensor 124, the third SAR sensor 125 and the fourth SAR sensor 126 can be different from that of the first SAR sensor 104, and the difference can only be that the connected frame areas are different to achieve SAR detection of different frame areas. Specifically, the second SAR sensor 124, the third SAR sensor 125 and the fourth SAR sensor 126 can each include a SAR sensor IC, and the frame area included by each SAR sensor is connected with the corresponding SAR sensor IC. The frame area included by each SAR sensor can be grounded or not grounded, and can be set according to 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 FIG. 14, which is an embodiment in which each SAR sensor is grounded through a capacitor. Correspondingly, when the frame area included by the SAR sensor does not need to be grounded, the corresponding capacitor can not be set.

[0062] In the first SAR sensor 104, the second SAR sensor 124, the third SAR sensor 125 and the fourth SAR sensor 126, the frame areas in different SAR sensors can be connected with different SAR sensor chips. In addition, the first SAR sensor 104, the second SAR sensor 124, the third SAR sensor 125 and the fourth SAR sensor 126 can also multiplex the same SAR sensor chip. Please refer to FIG. 14, in the embodiment of the present application, the first SAR sensor 104 includes a first sensing branch 1041 and a SAR sensor chip 1042, the second SAR sensor 124 includes a second sensing branch 1241 and the SAR sensor chip 1042, the third SAR sensor 125 includes a third sensing branch 1251 and the SAR sensor chip 1042, and the fourth SAR sensor 126 includes a fourth sensing branch 1261 and the SAR sensor chip 1042. The SAR sensor chip 1042 is a chip arranged inside the electronic device, and the first sensing branch 1041, the second sensing branch 1241, the third sensing branch 1251 and the fourth sensing branch 1261 are different frame areas in the conductive frame 100, for example, in the embodiment shown in FIG. 3, the first sensing branch 1041 includes the frame area between the HD segments, the second sensing branch 1241 includes the frame area between the SU segments, the third sensing branch 1251 includes the frame area between the VW segments, and the fourth sensing branch 1261 includes the frame area between the JI segments.

[0063] Or, in the embodiment shown in FIG. 8, the first inductive branch 1041 includes the frame region between the HD" segments, the second inductive branch 1241 includes the frame region between the SU segments, the third inductive branch 1251 includes the frame region between the VW segments, and the fourth inductive branch 1261 includes the frame region between the JI segments.

[0064] Or, in the embodiment shown in FIG. 10, the first inductive branch 1041 includes the frame region between the HD" segments, the second inductive branch 1241 includes the frame region between the SU" segments, the third inductive branch 1251 includes the frame region between the VW segments, and the fourth inductive branch 1261 includes the frame region between the JI segments.

[0065] It should be noted that, in specific implementation, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be selectively added according to the cost, product price, market, and necessity of OTA improvement. For example, in some regions, only the first SAR sensor 104 can be provided to ensure the free, handheld performance of the medium-high frequency MHB without reducing the body SAR. For other regions, to ensure that the SAR hotspot of the top first antenna 101 can be completely covered by the sensor, the first SAR sensor 104 and the fourth SAR sensor 126 need to be provided at the same time to realize the free, handheld performance of the first antenna 101 and ensure that the body SAR is not reduced in this scenario. For products with high cost-bearing capacity of flagship models, to further improve the performance, the second SAR sensor 124 can be added to further improve the free and horizontal screen performance of the fourth antenna 113.

[0066] In addition, in some embodiments, the third SAR sensor 125 can be further added, and the antenna switch configuration can be adjusted by combining different SAR sensor triggering logics and software algorithms to further optimize the OTA performance.

[0067] In this implementation, by causing the electronic device to further include at least one of the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126, the OTA and other antenna performances of the antennas in the electronic device can be further optimized.

[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 to:

[0069] In a case that 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.

[0070] In a case that 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] In a case that 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.

[0072] The first SAR sensor 104 is in a triggered state, i.e., the first SAR sensor 104 detects that a human body is close to the first antenna 101. Correspondingly, the first SAR sensor 104 is in a non-triggered state, i.e., the first SAR sensor 104 does not detect that a human body is close to the first antenna 101. The second SAR sensor 124 is in a triggered state, i.e., the second SAR sensor 124 detects that a human body is close to the fourth antenna 113. Correspondingly, the second SAR sensor 124 is in a non-triggered state, i.e., the second SAR sensor 124 does not detect that a human body is close to the fourth antenna 113. The third SAR sensor 125 is in a triggered state, i.e., the third SAR sensor 125 detects that a human body is close to the fifth antenna 121. Correspondingly, the third SAR sensor 125 is in a non-triggered state, i.e., the third SAR sensor 125 does not detect that a human body is close to the fifth antenna 121.

[0073] In this way, the antenna switch configuration can be adjusted by a software algorithm in the electronic device based on the triggered states of the first SAR sensor 104, the second SAR sensor 124 and the third SAR sensor 125, so as to further optimize the OTA performance. For example, when the electronic device is configured with the first SAR sensor 104, the second SAR sensor 124 and the third SAR sensor 125 as three-channel SAR sensors, the software optimization algorithm can be as follows:

[0074] If the second SAR sensor 124 and the third SAR sensor 125 are triggered, and the first SAR sensor 104 is not triggered, it is determined that the scene is a vertical screen handheld scene, and the MHB transmitting antenna can be set at the first antenna 101, and the resonance efficiency of each band is slightly biased to transmission to improve the transmission performance, and the second antenna 102, the fifth antenna 121 and the sixth antenna 122 are set to slightly bias the receiving performance design to achieve the optimal transmission and reception performance of the MHB in the vertical screen scene of the whole machine.

[0075] If the first SAR sensor 104 and the third SAR sensor 125 are triggered, and the second SAR sensor 124 is not triggered, it is determined that the scene is a horizontal screen handheld scene. The MHB transmitting antenna can be further set at the sixth antenna 122, and the resonance efficiency of each band is slightly biased to transmission to improve the transmission performance, and the first antenna 101, the second antenna 102 and the fifth antenna 121 are set to slightly bias the receiving performance design to achieve the optimal transmission and reception performance of the MHB in the vertical screen scene of the whole machine.

[0076] If the first SAR sensor 104 and the second SAR sensor 124 are triggered, and the third SAR sensor 125 is not triggered, it is determined that the scene is a head scene or a head-hand conversation scene. Since the third SAR sensor 125 is not triggered due to the fact that the hand is far away from the fifth antenna 121 at the bottom in this scene. At this time, the transmitting antenna corresponding to the fifth antenna 121 can be set to not reduce the body SAR mode, so as to improve the head-hand conversation performance of the fifth antenna 121. In addition, in the case of some specific appearances (such as a three-dimensional (3-dimensional, 3D) curved screen), the SAR of the sixth antenna 122 can meet the standard without reducing the power, and the maximum direction of the body SAR of the sixth antenna 122 is generally perpendicular to the frame and far away from the head. At this time, the sixth antenna 122 also does not need to reduce the body SAR, so as to improve the head-hand conversation transmission capability of the sixth antenna 122.

[0077] Please refer to FIG. 1, the third SAR sensor 125 is located near the vice plate 130 of the electronic device, and the UV segment is adjacent to the USB interface 139 of the electronic device.

[0078] In this embodiment, by using the triggering state of the first SAR sensor 104, the second SAR sensor 124 and the third SAR sensor 125, the software algorithm in the electronic device is used to adjust the antenna switch configuration, so as to further optimize the OTA performance.

[0079] Please refer to FIG. 1, FIG. 1 is an electronic device with 7 breaks provided by an embodiment of the present application, and the specific structure has the following characteristics:

[0080] SAR sensor: the SAR sensor is composed of a SAR sensor IC and a frame area corresponding to the SAR sensor IC, wherein the frame area corresponding to the SAR sensor IC forms a sensor of the SAR sensor. The frame area corresponding to the SAR sensor IC cannot be directly grounded, and can be grounded through a capacitor to ensure the function of the SAR sensor. As shown in FIG. 14, the first SAR sensor 104 draws a capacitive grounding schematic, and actually, when the second SAR sensor 124, the third SAR sensor 125 and the fourth SAR sensor 126 that are the SAR sensors multiplex the antenna radiator to serve as the SAR sensor, all need to be grounded through a capacitor, and whether to increase is not specifically illustrated according to the design needs. In some embodiments of the present application, the electronic device at least includes the first SAR sensor 104, and the first SAR sensor 104 at least includes the top GH section radiator and the right part of the side DG section mainboard 129 radiator in FIG. 1. So as to ensure that the first SAR sensor 104 can be used for the top first antenna 101 (radiated through the first break 109) and the side second antenna 102 (radiated through the second break 110) at the same time, and the transmission performance of the MHB FS and the vertical screen handheld scene is optimized.

[0081] MHB free, hand transmission performance: the first antenna 101 radiated through the first break 109.

[0082] MHB head hand / gaming hand: the first preferred scheme is realized through the sixth antenna 122, which can be the OP section radiator radiated through the seventh break 118 or the PR section radiator radiated through the third break 114. In addition, when there are two or more antennas in the electronic device that share the same power amplifier (PA), the antennas far away from the PA need to be connected to the PA through longer printed circuit board (PCB) traces, and the corresponding transmission loss is also larger. Therefore, in order to improve the transmission performance, the number of PAs in the electronic device can be increased according to the product cost bearing capacity, for example, a separate PA can be provided for each antenna, or only the antennas close to each other share the same PA, and the antennas far away from each other are provided with a separate PA to shorten the length of the PCB trace, so as to reduce the transmission loss. In addition, in order to reduce the transmission loss, the PCB trace connected to the antenna in the electronic device can be replaced with a cable line. Since the transmission loss of the cable line is smaller than that of the PCB trace, replacing the PCB trace with the cable line can also reduce the transmission loss. The second preferred scheme of the MHB head hand is realized through the fifth antenna 121, and the head SAR is basically not reduced, and the head hand is better than the first antenna 101 and the second antenna 102.

[0083] Low frequency free, hand, head hand / game hand: The low frequency of the whole machine is composed of two low frequency hands, heads, and relatively small antennas for horizontal screen game power reduction. The design features of the scheme are: ① The third antenna 103 is arranged on the right side of the mainboard 129, and is radiated by the AC section radiator through the second break 110. The distance LS1 from the second break 110 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm. Thus, please refer to FIG. 2, which is a schematic diagram of an antenna head hand simulation model. As shown in FIG. 2, when LS1 is more than 100mm, the hand cannot hold in this mode. ② The other low frequency is arranged on the fourth antenna 113, which has two breaks, at least one of which is the third break 114. The distance LS5 from the third break 114 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm (generally located above the power key). In this way, the low frequency free index can be improved while reducing the impact of hand holding. As shown in FIG. 1, this antenna can be excited by the metal radiator SU between the third break 114 and the fifth break 116 to radiate through the two breaks. This antenna has double-break radiation, and the free aperture efficiency is relatively high. The two low frequency antennas are far away from the head, and the overall hand holding power reduction is small compared with the prior art. The low frequency of the whole machine can be free, hand, head hand, and horizontal screen, and can be compatible with the performance of all scenes.

[0084] According to the cost, product price, market, and the necessity of OTA improvement, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be selectively added. For example, in some areas: only the first SAR sensor 104 can be set to ensure the best free and handheld performance of the medium and high frequency MHB without reducing the bodySAR. For other areas, to ensure that the SAR hot spot of the top first antenna 101 can be completely covered by the sensor, the first SAR sensor 104 and the fourth SAR sensor 126 need to be set at the same time to realize the best free and handheld performance of the first antenna 101, and to ensure that the bodySAR is not reduced in this scenario. For products with high cost tolerance, to further improve performance, the second SAR sensor 124 can be added to further improve the free and horizontal screen performance of the fourth antenna 113.

[0085] In addition, in some embodiments, the third SAR sensor 125 can be further added, and the antenna switch configuration can be adjusted by combining different SAR sensor trigger logic and software algorithms to further optimize the OTA performance.

[0086] Optionally, referring to FIG. 3, the first frame 105 further comprises a tenth contact point 127 grounded between the first break 109 and the fourth break 115, the first antenna 101 further comprises a frame area between the tenth contact point 127 and the first break 109, and a feeding point of the first antenna 101 is located between the tenth contact point 127 and the first break 109, and a feeding point of the positioning antenna 123 corresponding to the positioning antenna is located between the fourth contact point 120 and the fourth break 115.

[0087] Referring to FIG. 1, the tenth contact point 127 is located near a front camera 128 of the electronic device. The tenth contact point 127 can be directly grounded, or the tenth contact point 127 can be grounded through a capacitor.

[0088] In this embodiment, to solve the problem of the HG part of the first antenna 101 and the second antenna 102, the middle frequency resonance of the first antenna 101 is achieved by exciting the top ZI section radiator, and because the GPS frequency (1575 MHz) is very close to the middle frequency B3 (1710-1880 MHz), the GPS antenna needs to be adjusted to the F23 feeding point in FIG. 3 after the ZI excitation B3, and the LK branch is excited to achieve the isolation of the GPS and the B3 mode of the first antenna 101, and the B3 mode of the first antenna 101 and the B3 (DF branch excitation) mode of the second antenna 102 are isolated, so as to ensure that the efficiency of the first antenna 101 and the GPS antenna can be better compatible.

[0089] Referring to FIG. 3, FIG. 3 is an electronic device provided by an embodiment of the present application, and the specific structure has the following characteristics:

[0090] SAR sensor: the SAR sensor is composed of a SAR sensor IC and a corresponding frame area, and the corresponding frame area cannot be directly grounded, and can be grounded through a capacitor to ensure the SAR sensor function. As shown in FIG. 14, the first SAR sensor 104 draws a capacitor grounding schematic, and in fact, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 as SAR sensors all need to be grounded through a capacitor when multiplexing the antenna radiator, and whether to increase is not specifically illustrated according to design needs. In some embodiments of the present application, the electronic device at least includes the first SAR sensor 104, and the first SAR sensor 104 at least includes the top GH section radiator and the right side portion of the DG section mainboard 129 radiator in FIG. 3. To ensure that the first SAR sensor 104 can be used for the top first antenna 101 (radiated through the first break 109) and the side second antenna 102 (radiated through the second break 110) at the same time, the transmission performance of the MHB FS and the vertical screen handheld scene is optimized.

[0091] MHB free, hand transmission performance: realized by the MHB position 1# antenna radiated through the first break 109. To solve the HG portion radiator of the first antenna 101 and the second antenna 102 common ground isolation problem, the middle frequency resonance of the first antenna 101 is realized through the excitation of the top ZI section radiator in the embodiments of the present application. At the same time, because the GPS frequency (1575 MHz) is very close to the middle frequency B3 (1710-1880 MHz), after the ZI excitation B3, the GPS antenna needs to be adjusted to the F23 feeding point in FIG. 3, and the GPS and the B3 mode isolation of the first antenna 101 are realized by the LK branch excitation. At the same time, the B3 mode of the first antenna 101 and the B3 (DF branch excitation) mode of the second antenna 102 can be isolated, so that the efficiency of the first antenna 101, the second antenna 102, and the GPS antenna can be better compatible.

[0092] MHB head hand / game hand: the first choice is realized by the sixth antenna 122, which can be the OP section radiator radiated through the seventh break 118, or the PR section radiator radiated through the third break 114. In order to improve the transmission performance, the number of PAs in the electronic device can be increased according to the product cost bearing capacity. In addition, in order to reduce the transmission loss, the PCB wiring of the antenna connection in the electronic device can be replaced by a cable. The second choice of the MHB head hand is realized by the fifth antenna 121, which is far away from the head SAR and does not decrease, and the head hand is better than the first antenna 101 and the second antenna 102.

[0093] Low frequency free, hand, head hand / game hand: The low frequency of the whole machine is composed of two low frequency hands, heads, and relatively small antennas for horizontal screen game power reduction. The design features of the scheme are: ① The third antenna 103 is arranged on the right side of the mainboard 129, and is radiated by the AC section radiator through the second break 110. The distance LS1 from the second break 110 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm. Thus, please refer to FIG. 2, which is a schematic diagram of an antenna head hand simulation model. As shown in FIG. 2, when LS1 is more than 100mm, the hand cannot hold in this mode. ② The other low frequency is arranged on the fourth antenna 113, which has two breaks, at least one of which is the third break 114. The distance LS5 from the third break 114 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm (generally located above the power key). In this way, the low frequency free index can be improved while reducing the impact of hand holding. As shown in FIG. 3, this antenna can be excited by the metal radiator SU between the third break 114 and the fifth break 116 to radiate through the two breaks. This antenna has double-break radiation, and the free aperture efficiency is relatively high. The two low frequency antennas are far away from the head, and the overall hand holding power reduction is small compared with the prior art. The low frequency of the whole machine can be free, hand, head hand, and horizontal screen, and can be compatible with the performance of all scenes.

[0094] According to the cost, product price, market, and the necessity of OTA improvement, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be selectively increased. For example, in some areas: only the first SAR sensor 104 can be set to ensure the best free and handheld performance of the medium and high frequency MHB without reducing the bodySAR. For other areas, to ensure that the SAR hot spot of the top first antenna 101 can be completely covered by the sensor, the first SAR sensor 104 and the fourth SAR sensor 126 need to be set at the same time to realize the best free and handheld performance of the first antenna 101, and to ensure that the bodySAR is not reduced in this scenario. For products with high cost tolerance, to further improve performance, the second SAR sensor 124 can be added to further improve the free and horizontal screen performance of the fourth antenna 113.

[0095] In addition, in some embodiments, the third SAR sensor 125 can be further increased, and the OTA performance can be further optimized by adjusting the antenna switch configuration in combination with different SAR sensor trigger logic and software algorithms.

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

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

[0098] Compared with the embodiment shown in FIG. 1, the embodiment has the difference that the eighth break 133 is additionally provided in the fourth frame 108.

[0099] Referring to FIG. 5, FIG. 5 is an electronic device with 8 breaks provided by an embodiment of the present application, and the specific structure has the following characteristics:

[0100] SAR sensor: The SAR sensor is composed of a SAR sensor IC and a corresponding frame area, and the corresponding frame area cannot be directly grounded, but can be grounded through a capacitor to ensure the function of the SAR sensor. As shown in FIG. 14, the first SAR sensor 104 draws a capacitor grounding diagram, and in fact, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126, which are used as SAR sensors, need to be grounded through a capacitor when they are multiplexed with the antenna radiator. According to the design needs, whether to increase or not is not specifically illustrated. In some embodiments of the present application, the electronic device at least includes the first SAR sensor 104, and the first SAR sensor 104 at least includes the top GH section radiator in FIG. 5 and the right part of the side DG section mainboard 129 radiator, so as to ensure that the first SAR sensor 104 can be used for the top first antenna 101 (radiated through the first break 109) and the side second antenna 102 (radiated through the second break 110) at the same time, and the transmitting performance of the MHB FS and the vertical screen handheld scene is optimized.

[0101] MHB free, hand-held performance: MHB position 1# antenna is realized by the first break 109. In order to solve the problem of the HG part of the first antenna 101 and the second antenna 102 being co-located, the intermediate frequency resonance of the first antenna 101 is realized by exciting the top ZI section radiator, and because the GPS frequency (1575 MHz) is very close to the intermediate frequency B3 (1710-1880 MHz), the GPS antenna needs to be adjusted to the F23 feed in FIG. 5 after the ZI excitation B3, and the LK branch excitation realizes the GPS and the B3 mode isolation of the first antenna 101, and at the same time, the B3 mode of the first antenna 101 and the B3 (DF branch excitation) mode of the second antenna 102 can be isolated, so that the efficiency of the first antenna 101, the second antenna 102 and the GPS antenna can be better compatible.

[0102] MHB head hand / game hand: the first choice is realized by the sixth antenna 122, which can be an OP section radiator radiated through the seventh break 118, or a PR section radiator radiated through the third break 114. In order to improve the conduction performance, the number of PAs in the electronic device can be increased according to the product cost bearing capacity. In addition, in order to reduce transmission loss, the PCB wiring of the antenna connection in the electronic device can also be replaced by cable. The second choice of MHB head hand is realized by the fifth antenna 121, which is far away from the head SAR and is better than the first antenna 101 and the second antenna 102.

[0103] Low frequency free, hand-held, head hand / game hand: the whole machine low frequency is composed of two low frequency hand-held, head, and horizontal screen game with relatively small reduction of the antenna. The design features of the scheme are as follows: ① the third antenna 103 is arranged on the right side of the mainboard 129, and is radiated by the AC section radiator through the second break 110. The distance from the second break 110 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm. As shown in FIG. 2, when the distance is more than 100mm, the hand cannot hold in this mode. ② the other low frequency is arranged on the fourth antenna 113, which has two breaks, at least one of which is the third break 114, and the distance from the third break 114 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm (generally located on the upper side of the power key), so as to improve the low frequency free index and help reduce the hand holding influence. By adding the eighth break 133 in the fourth frame 108, the fourth antenna 113 is excited by the SU” branch and the ground U’T, and is radiated through the third break 114 and the eighth break 133. This antenna has double-break radiation and high free aperture efficiency. The two low frequency antennas are far away from the head, the whole machine low frequency has small reduction of the hand, and the horizontal screen positive and negative holding cannot hold the two low frequencies, so that the whole machine low frequency can be compatible with the performance of free, hand-held, head hand and horizontal screen in all scenes.

[0104] According to the cost, product price, market, and the necessity of OTA improvement, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be selectively added. For example, in some regions, only the first SAR sensor 104 can be arranged to ensure the free, handheld performance of the medium-high frequency MHB without reducing the body SAR. For other regions, to ensure that the SAR hotspot of the top first antenna 101 can be completely covered by the sensor, the first SAR sensor 104 and the fourth SAR sensor 126 need to be arranged at the same time to realize the free, handheld performance of the first antenna 101, and ensure that the body SAR is not reduced in this scenario. For flagship models with high cost tolerance, to further improve the performance, the second SAR sensor 124 can be added to further improve the free and horizontal screen performance of the fourth antenna 113.

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

[0106] In this embodiment, by arranging 8 breaks in the conductive frame 100, the electronic device can have good antenna performance in medium-high frequency and low frequency.

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

[0108] Referring to FIGS. 1 and 3, in some other embodiments of the present application, the first grounding point 111 and the second grounding point 112 are connected through the frame, and the first SAR sensor 104 further includes a frame area between the first grounding point 111 and the second break 110, that is, the first SAR sensor 104 can also be used for SAR detection of the frame area between the first grounding point 111 and the second break 110.

[0109] Please refer to FIG. 1 and FIG. 3, which are schematic diagrams of the direct connection between the first grounding point 111 and the second grounding point 112 through the frame. Please refer to FIG. 7, which is different from the embodiment shown in FIG. 1 in that the ninth breakage 136 is added between the first grounding point 111 and the second grounding point 112.

[0110] Please refer to FIG. 7, which is an electronic device with 8 breaks provided by an embodiment of the present application, and the specific structure has the following characteristics:

[0111] By setting the ninth breakage 136, there is no mutual coupling problem between the second antenna 102 and the first antenna 101, so that the first antenna 101 can flexibly use ZI section or GH section to excite intermediate frequency, and the design of GPS / wireless fidelity (wifi) / L5 antenna on both sides of the fourth breakage 115 has low restriction, the extra ninth breakage 136 can be used to design other antennas such as L5 / N78 / wifi, and the performance of L5 / wifi / sub6G antenna can be further improved while ensuring LMH.

[0112] SAR sensor: The SAR sensor is composed of a SAR sensor IC and a metal conductor, and the metal conductor cannot be directly grounded and can be grounded through a capacitor to ensure the function of the SAR sensor. In some embodiments of the present application, the electronic device at least includes a first SAR sensor 104, and the first SAR sensor 104 at least includes the top GH section radiator and the right side GD" section mainboard 129 radiator in FIG. 7. So that the first SAR sensor 104 can be used for SAR detection of the top first antenna 101 (radiated through the first breakage 109) and the side second antenna 102 (radiated through the second breakage 110) at the same time.

[0113] MHB free, manual emission performance: realized by the first antenna 101 radiated through the first breakage 109. The first antenna 101 can flexibly use ZI section or GH section to excite intermediate frequency according to the GPSwifi antenna design of the fourth breakage 115.

[0114] MHB head hand / game hand: the first choice is realized through the sixth antenna 122, which can be an OP segment radiator radiating through the seventh break 118, or a PR segment radiator radiating through the third break 114. Among them, for the second antenna 102, when the current of the medium-high frequency mode is strongest at the D point and weakest at the D' point, the head SAR is lower than that of the OP segment corresponding antenna, at this time, the second antenna 102 can also realize the head hand performance not worse than that of the OP segment corresponding antenna, that is, in this case, the head hand performance of the medium-high frequency mode can also be realized through the second antenna 102. It should be noted that when the head hand performance of the medium-high frequency mode is realized based on the second antenna 102, the distance between the feeding point E of the second antenna 102 and the first frame 105 is greater than the distance between the second grounding point 112 and the first frame 105. In order to improve the transmission performance, the number of PAs in the electronic device can be increased according to the product cost bearing capacity. In addition, in order to reduce the transmission loss, the PCB wiring connected by the antenna in the electronic device can also be replaced by a cable. The second choice of MHB head hand is realized through the fifth antenna 121, which is far away from the head SAR and basically does not decrease, and the head hand is better than the first antenna 101 and the second antenna 102.

[0115] Low frequency free, hand, head hand / game hand: the whole machine low frequency is composed of two low frequency hands, head, and horizontal screen game with relatively small antenna. The design features of the scheme are: ① the third antenna 103 is arranged at the right side of the mainboard 129, and is radiated by the AC segment radiator through the second break 110. The distance from the second break 110 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm. As shown in FIG. 2, which is a schematic diagram of an antenna head hand simulation model, when LS1 is more than 100mm, the hand cannot be held in this mode. ② The other low frequency is arranged in the fourth antenna 113, which has two breaks, at least one of which is the third break 114. The distance from the third break 114 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm (generally located above the power key). In this way, the low frequency free index can be improved while helping to reduce the hand holding effect. As shown in FIG. 7, this antenna can be excited by the metal radiator SU between the third break 114 and the fifth break 116 to radiate through the two breaks. This antenna has double-break radiation, and the free aperture efficiency is high. The two low frequency antennas are far away from the head, the whole machine hand holding reduction is small compared with the prior art, and the horizontal screen positive and negative holding cannot hold the two low frequencies, and the whole machine low frequency can be compatible with the performance of free, hand, head hand, and horizontal screen full scene.

[0116] According to the cost, product price, market, and the necessity of OTA improvement, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be selectively added. For example, in some regions, only the first SAR sensor 104 can be set to ensure the free, handheld performance of the medium-high frequency MHB without reducing the body SAR. For other regions, to ensure that the SAR hotspot of the top first antenna 101 can be completely covered by the sensor, the first SAR sensor 104 and the fourth SAR sensor 126 need to be set at the same time to realize the free, handheld performance of the first antenna 101, and ensure that the body SAR is not reduced in this scenario. For flagship models with high cost tolerance, to further improve the performance, the second SAR sensor 124 can be added to further improve the free and horizontal screen performance of the fourth antenna 113.

[0117] In addition, in some embodiments, a third SAR sensor 125 can be further added, and the OTA performance can be further optimized by adjusting the antenna switch configuration in combination with different SAR sensor triggering logics and software algorithms.

[0118] In this embodiment, by setting 8 breaks in the conductive frame 100, the electronic device can have good antenna performance in medium-high frequency and low frequency.

[0119] Optionally, referring to FIG. 9, the fourth frame 108 is further provided with an eighth break 133 located between the third break 114 and the third frame 107, and the fourth frame 108 is further provided with a fifth grounding point 134 located between the eighth break 133 and the third frame 107; the third frame 107 further includes a sixth grounding point 135 located between the fifth break 116 and the fourth frame 108; the third antenna 103 includes a frame region between the third break 114 and the fifth grounding point 134, and the fifth antenna 121 further includes a frame region between the fifth break 116 and the sixth grounding point 135.

[0120] The second frame 106 is further provided with a ninth break 136 located between the first grounding point 111 and the second grounding point 112, and the first SAR sensor 104 further includes a frame region between the first grounding point 111 and the ninth break 136.

[0121] Compared with the embodiment shown in FIG. 1, the difference of this embodiment is that the eighth break 133 is added in the fourth frame 108, and the ninth break 136 is added between the first grounding point 111 and the second grounding point 112.

[0122] Please refer to FIG. 9, which is an electronic device with 9 breaks provided by an embodiment of the application, and the specific structure has the following features:

[0123] By setting the ninth break 136, there is no mutual coupling problem between the second antenna 102 and the first antenna 101, so that the first antenna 101 can flexibly use ZI or GH section to excite intermediate frequency, and the design restriction of the GPS / wifi / L5 antenna on both sides of the fourth break 115 is low, and the extra ninth break 136 can be used to design other antennas such as L5 / N78 / wifi, etc. While ensuring LMH, the performance of L5 / wifi / sub6G antenna can be further improved.

[0124] SAR sensor: The SAR sensor is composed of a SAR sensor IC and a metal conductor, and the metal conductor cannot be directly grounded, but can be grounded through a capacitor to ensure the function of the SAR sensor. In some embodiments of the application, the electronic device at least includes a first SAR sensor 104, and the first SAR sensor 104 at least includes the top GH section radiator and the right side GD" section mainboard 129 radiator. To ensure that the first SAR sensor 104 can be used for SAR detection of the top first antenna 101 (radiated through the first break 109) and the side second antenna 102 (radiated through the second break 110).

[0125] MHB free, manual emission performance: The first antenna 101 radiated through the first break 109. The first antenna 101 can flexibly use ZI or GH section to excite intermediate frequency according to the GPSwifi antenna design of the fourth break 115.

[0126] MHB head hand / game hand: the first choice is realized through the sixth antenna 122, which can be the OP segment radiator radiating through the seventh break 118, or the PR segment radiator radiating through the third break 114. Among them, for the second antenna 102, when the current of the medium-high frequency mode is strongest at the D point and weakest at the D' point, the head SAR is lower than that of the OP segment corresponding antenna, at this time, the second antenna 102 can also realize the head hand performance not worse than that of the OP segment corresponding antenna, that is, in this case, the head hand performance of the medium-high frequency mode can also be realized through the second antenna 102. It should be noted that when the head hand performance of the medium-high frequency mode is realized based on the second antenna 102, the distance between the feeding point E of the second antenna 102 and the first frame 105 is greater than the distance between the second grounding point 112 and the first frame 105. In order to improve the transmission performance, the number of PAs in the electronic device can be increased according to the product cost bearing capacity. In addition, in order to reduce the transmission loss, the PCB wiring connected by the antenna in the electronic device can also be replaced by a cable. The second choice of MHB head hand is realized through the fifth antenna 121, which is far away from the head SAR and basically does not decrease, and the head hand is better than the first antenna 101 and the second antenna 102.

[0127] Low frequency free, hand, head hand / game hand: the whole machine low frequency is composed of two low frequency hands, head, and horizontal screen game with relatively small antenna. The design features of the scheme are: ① the third antenna 103 is arranged in the right side area of the mainboard 129, and is radiated by the AC segment radiator through the second break 110. The distance from the second break 110 to the bottom of the electronic device is not less than 85mm, and can be more than 100mm. As shown in FIG. 2, which is a schematic diagram of an antenna head hand simulation model, when LS1 is more than 100mm, the hand cannot be held in this mode. ② The other low frequency is arranged in the fourth antenna 113, which has two breaks, at least one of which is the third break 114, which is arranged to be not less than 85mm from the bottom of the electronic device, and can be more than 100mm (generally located above the power key). In this way, the low frequency free index can be improved while helping to reduce the hand holding effect. By adding an eighth break 133 in the fourth frame 108, the fourth antenna 113 is excited by the SU" branch and the grounded U'T, and is radiated through the third break 114 and the eighth break 133. This antenna has double-break radiation and high free aperture efficiency. The two low frequency antennas are far away from the head, the whole machine has small hand holding reduction, and the horizontal screen positive and negative holding cannot hold the two low frequencies, and the whole machine low frequency can be free, hand, head hand, and horizontal screen scene can be considered.

[0128] According to the cost, product price, market, and the necessity of OTA improvement, the second SAR sensor 124, the third SAR sensor 125, and the fourth SAR sensor 126 can be selectively added. For example, in some regions, only the first SAR sensor 104 can be set to ensure the free, handheld performance of the medium-high frequency MHB without reducing the body SAR. For other regions, to ensure that the SAR hotspot of the top first antenna 101 can be completely covered by the sensor, the first SAR sensor 104 and the fourth SAR sensor 126 need to be set at the same time to realize the free, handheld performance of the first antenna 101, and ensure that the body SAR is not reduced in this scenario. For flagship models with high cost tolerance, to further improve the performance, the second SAR sensor 124 can be added to further improve the free and horizontal screen performance of the fourth antenna 113.

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

[0130] In this embodiment, by setting 9 breaks in the conductive frame 100, the electronic device can have good antenna performance in medium-high frequency and low frequency.
