Background

With the development of communication technologies, electronic devices such as smart phones have more and more functions, and people enjoy various conveniences brought by the electronic devices and pay more and more attention to the influence of electromagnetic radiation generated by the electronic devices on human health.

Generally, in the process of designing an antenna, the influence of electromagnetic radiation generated by an electronic device on a human body is evaluated through an electromagnetic absorption rate (SAR) index. The larger the SAR value, the larger the influence on the human body. Particularly, when the electronic devices are operated very close to the human body (such as the head, the hands, etc.), the human body absorbs the electromagnetic energy, thereby affecting the human body.

In the related art, the distance between the electronic device and the human body is often detected by a sensor, so that the power of the antenna is reduced when the electronic device approaches the human body, and the SAR value is reduced. However, reducing the power of the antenna may degrade the performance of the antenna.

Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to fig. 1 to 13 in the embodiments of the present application. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

The embodiment of the application provides an electronic device 10, where the electronic device 10 may be a smart phone, a tablet computer, or other devices, and may also be a game device, an Augmented Reality (AR) device, an automobile device, a data storage device, an audio playing device, a video playing device, a notebook computer, a desktop computing device, or other devices. Referring to fig. 1 and fig. 2, fig. 1 is a first schematic structural diagram of an electronic device 10 provided in the embodiment of the present application, and fig. 2 is a second schematic structural diagram of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may include a first SAR inductor 111, a second SAR inductor 112, an antenna arrangement 120, and a processor 130.

As shown in fig. 1 and 2, the electronic device 10 may further include a first frame 101, a second frame 102, and a third frame 103, which are connected in sequence, and the first frame 101 may be disposed opposite to the third frame 103. The electronic device 10 may further be provided with a first area 105 and a second area 106, where the first area 105 may be an area on the second frame 102 close to the first frame 101, and a distance between the first area 105 and the first frame 101 is smaller than a distance between the first area 105 and the third frame 103; the second area 106 may be an area on the second frame 102 close to the third frame 103, and the distance between the second area 106 and the third frame 103 is smaller than the distance between the second area 106 and the first frame 101. The first SAR inductor 111 may be disposed in the first region 105 of the second frame 102 close to the first frame 101, and the second SAR inductor 112 may be disposed in the second region 106 of the second frame 102 close to the third frame 103. The antenna device 120 may be disposed on the electronic apparatus 10, and the antenna device 120 may have a first main radiation direction when the electronic apparatus 10 is in a free state, and the first main radiation direction may be deviated from a direction of a centerline L0 of the second frame 102. The processor 130 may be electrically connected to the antenna device 120, and the processor 130 may also be electrically connected to the first SAR inductor 111 and the second SAR inductor 112 directly or indirectly; the processor 130 may determine whether the electronic device 10 is in the head-hand state according to the detection values of the first SAR sensor 111 and the second SAR sensor 112, and when it is determined that the electronic device 10 is in the head-hand state according to the detection values of the first SAR sensor 111 and the second SAR sensor 112, the processor 130 may control the antenna apparatus 120 to have a second main radiation direction, which is concentrated in the direction of the center line L0 of the second frame 102. It can be understood that the head-hand state in the embodiment of the present application may include a left-hand state (BL state) and a right-hand state (BH state), or may include a left-head-hand state (BHHL) and a right-head-hand state (BHHR), and any one of the four states may be the head-hand state in the embodiment of the present application.

As shown in fig. 1 and 2, the lengths of the first frame 101 and the third frame 103 may be greater than the length of the second frame 102, so that the first frame 101 and the third frame 103 are long frames and the second frame 102 is a short frame. Also, the second frame 102 may be a bottom frame of the electronic device 10 in a free state or when being held vertically, the first area 105 may be a left area of the bottom frame, and the second area 106 may be a right area of the bottom frame.

The free state of the electronic device 10 is opposite to the head-hand state of the electronic device 10. The head-hand state of the electronic device 10 means that the electronic device 10 is held by the hand of the user or held by the hand of the user and close to the head. For example, referring to fig. 3 and 4, fig. 3 is a schematic diagram illustrating the electronic device 10 shown in fig. 1 in a first head-hand state of being held by a right hand, and fig. 4 is a schematic diagram illustrating the electronic device 10 shown in fig. 1 in a second head-hand state of being held by a left hand. As shown in fig. 3 and 4 (note that fig. 3 and 4 are back views of the electronic device 10, and a back shell of the electronic device 10 faces a user), when the electronic device 10 is in a head-hand state, a hand of the user may hold at least one of the first SAR inductor 111 and the second SAR inductor 112 with a high probability, and in a normal state, in the head-hand state where the user holds the hand with a left hand or in the head-hand state where the user holds the hand with a right hand, the first SAR inductor 111 and the second SAR inductor 112 may be simultaneously held by the hand of the user with a high probability. However, due to different holding postures, the two sensors are held by the hands of the user to different degrees, for example, as shown in fig. 3, the user mainly holds the first SAR sensor 111 and secondarily holds the second SAR sensor 112; as shown in fig. 4, the user primarily holds the second SAR inductor 112 and secondarily holds the first SAR inductor 111.

The first SAR inductor 111 and the second SAR inductor 112 are conductor structures, and when the head, the hand, and other parts of the user contact, cover, or shield the first SAR inductor 111 or the second SAR inductor 112, the first SAR inductor 111 or the second SAR inductor 112 and the human body part of the user, such as the head and the hand, may form an equivalent capacitor, and an equivalent capacitor is formed between the two, and the distance between the two decreases, the capacitance increases, and vice versa. Therefore, as the gesture of the user holding the electronic device 10 is different, the capacitance values detected by the first SAR inductor 111 and the second SAR inductor 112 are different, and the processor 130 can determine whether the head and the hand of the user are holding or approaching the electronic device 10 and what gesture the user is holding or approaching the electronic device 10 according to the capacitance values detected by the first SAR inductor 111 and the second SAR inductor 112, and further determine the current gesture of the electronic device 10.

It is understood that the processor 130 may be a control center of the electronic device 10, connect various portions of the entire electronic device 10 using various interfaces and lines, and perform various functions of the electronic device 10 and process data by running or calling computer programs stored in the memory, and calling data stored in the memory, thereby performing overall monitoring of the electronic device 10.

It is understood that, as shown in fig. 2, the electronic device 10 may further include a SAR sensor 113, the SAR sensor 113 may be electrically connected to the first SAR inductor 111, the second SAR inductor 112 and the processor 130, and the SAR sensor 113 may receive and process detection data of the first SAR inductor 111 and the second SAR inductor 112 to determine SAR values detected by the two inductors. The processor 130 may be electrically connected, directly or indirectly, to the SAR sensor 113 such that the processor 130 may determine the current pose of the electronic device 10 from the detected SAR value. It should be noted that, the processor 130 may also be directly electrically connected to the first SAR inductor 111 and the second SAR inductor 112 without passing through the SAR sensor 113, which is not limited in the embodiment of the present application.

Referring to fig. 5, fig. 5 is a radiation pattern of the electronic device 10 in a free state according to an embodiment of the present disclosure. When the electronic device 10 is in the free state, the SAR value of the electronic device 10 is low, the antenna apparatus 120 may be in the normal operation state, and the antenna apparatus 120 may have a first main radiation direction, which may deviate from the direction of the centerline L0 of the second frame 102, for example, the first main radiation direction may be toward the direction of the second region 106 (lower right side in fig. 5).

Referring to fig. 6, fig. 6 is a radiation pattern of the electronic device 10 in the head-hand state according to the embodiment of the present disclosure. When the electronic device 10 according to the embodiment of the application determines that the electronic device 10 is in the head-hand state according to the detection values detected by the first SAR inductor 111 and the second SAR inductor 112, the processor 130 of the electronic device 10 may control the antenna device 120, for example, but not limited to, control the adjusting circuit of the antenna device 120, so that the antenna device 120 has a second main radiation direction, which may be concentrated in the direction of the center line L0 of the second frame 102, at this time, the radiation pattern of the antenna device 120 may be concentrated in the middle areas of the top frame (the fourth frame 104) and the bottom frame (the second frame 102) of the electronic device 10, the second main radiation direction of the antenna device 120 is not easily held or blocked by the hands, the heads, and the head-hand state does not easily affect the radiation performance of the antenna device 120.

For example, please refer to table 1 below, where table 1 is a comparative table of radiation performance of the antenna device 120 under different conditions. As can be seen from table 1, when the electronic device 10 is in a head-hand state (e.g., a right-hand state), not only the SAR value of the electronic device 10 is high and easily exceeds the SAR threshold, but also the first main radiation direction of the antenna apparatus 120 is easily influenced by the hand holding, which results in a decrease in radiation performance of the antenna apparatus 120. However, when the electronic device 10 is in a head-hand state (e.g., a right head-hand state) and the processor 130 controls the antenna apparatus 120 to have the second main radiation direction, since the second main radiation direction is concentrated in a direction of a line L0 in the second frame 102, the second main radiation direction is not easily influenced by a hand of a user, and the radiation performance of the antenna apparatus 120 is not easily influenced by the hand of the user, for example, in the LTE B3 frequency band, the B7 frequency band, the B38 frequency band, and the B41 frequency band, the radiation performance of the antenna apparatus 120 having the second main radiation direction may be increased by 2.47dB at most, and the antenna apparatus 120 has a better head-hand radiation performance.

Table 1: radiation performance comparison table of antenna device under different states

In the electronic device 10 of the embodiment of the application, the first SAR inductor 111 is disposed in the first region 105 of the second frame 102 of the electronic device 10, which is close to the first frame 101, and the second SAR inductor 112 is disposed in the second region 106 of the second frame 102, which is close to the third frame 103; the antenna device 120 has a first main radiation direction when the electronic apparatus 10 is in a free state, and the first main radiation direction may be deviated from a direction in which a centerline L0 of the second frame 102 is located; when it is determined that the electronic device 10 is in the head-hand state according to the detection values of the first SAR sensor 111 and the second SAR sensor 112, the processor 130 may control the antenna device 120 to have a second main radiation direction, which may be centered in the direction of the centerline L0. Based on this, in the electronic device 10 according to the embodiment of the present application, the processor 130 may determine the current state and the user scene of the electronic device 10 according to the detection values of the two SAR inductors, and meanwhile, the processor 130 may control the antenna device 120 to change the radiation direction of the antenna device 120 when the electronic device 10 is in a head-hand state, regardless of a left head-hand state or a right head-hand state, so that the second main radiation direction of the antenna device 120 is in a second main radiation direction that is not easily held in any head-hand state. Therefore, the electronic device 10 of the present application changes its radiation direction in the head-hand state, and can ensure that the electronic device still has a better radiation performance in the head-hand state.

The processor 130 may determine that the electronic device 10 is in the head-hand state when the parameter difference value detected by the first SAR sensor 111 and the second SAR sensor 112 is greater than the first preset value.

It is understood that when the electronic device 10 is in the free state, the parameter detected by the first SAR inductor 111 should be an initial value, and the parameter detected by the second SAR inductor 112 should also be an initial value, and at this time, the difference value between the parameter detected by the first SAR inductor 111 and the parameter detected by the second SAR inductor 112 may be zero, and the processor 130 may determine that the electronic device 10 is in the free state.

When the electronic device 10 is in the head-hand state, due to the influence of the holding posture of the hand of the user, it always occurs that one SAR sensor is completely held by the palm of the hand of the user, and the other SAR sensor is not completely held by the hand of the user, at this time, there may be a difference in the parameters detected by the two SAR sensors, and when the difference value (here, the absolute value of the difference value) is greater than the first preset value, the processor 130 may determine that the electronic device 10 is in the head-hand state.

According to the detected values of the first SAR inductor 111 and the second SAR inductor 112, it can be determined that the electronic device 10 is in a left-handed/left-handed or right-handed/right-handed state. For example, when the data detected by the first SAR inductor 111 is greater than the data detected by the second SAR inductor 112 such that the difference between the first SAR inductor 111 and the second SAR inductor 112 detection parameters is greater than zero, the processor 130 may determine that the electronic device 10 is in a first right-handed state (right-handed/right-handed state) as shown in fig. 3. For another example, when the data detected by the second SAR inductor 112 is greater than the data detected by the first SAR inductor 111 such that the parameter difference detected by the first SAR inductor 111 and the second SAR inductor 112 is less than zero, the processor 130 may determine that the electronic device 10 is in the second left-handed state (left-handed/left-handed state) as shown in fig. 4.

It should be noted that, the above is only an exemplary description that the processor 130 determines the current state of the electronic device 10 according to the first SAR sensor 111 and the second SAR sensor 112, and the processor 130 may also determine the current state of the electronic device 10 according to other schemes, such as but not limited to, identifying the left head hand state according to the first SAR sensor 111 and identifying the right head hand state according to the second SAR sensor 112. This is not particularly limited in the examples of the present application.

The processor 130 of the embodiment of the application may determine the current state and the usage scenario of the electronic device 10 according to the size and the parameter difference of the parameters detected by the first SAR inductor 111 and the second SAR inductor 112, and the control method is simple and the scenario identification is accurate.

Please refer to fig. 7 and fig. 8, where fig. 7 is a third schematic structural diagram of the electronic device 10 provided in the embodiment of the present application, and fig. 8 is a fourth schematic structural diagram of the electronic device 10 provided in the embodiment of the present application. The electronic device 10 may also include a fourth bezel 104 and a third SAR inductor 114.

The fourth frame 104 may be disposed opposite to the second frame 102, and the fourth frame 104 may be connected to the first frame 101 and the third frame 103, respectively, so that the first frame 101, the second frame 102, the third frame 103, and the fourth frame 104 may be connected in sequence. The third SAR inductor 114 may be disposed in the third area 107 of the electronic device 10, and the third area 107 may be disposed near the fourth rim 104 and near the third rim 103, so that a distance between the third SAR inductor 114 and the fourth rim 104 may be smaller than a distance between the third SAR inductor 114 and the second rim 102, and a distance between the third SAR inductor 114 and the third rim 103 may be smaller than a distance between the third SAR inductor 114 and the first rim 101, so that the third SAR inductor 114 may also be disposed near the fourth rim 104 and the third rim 103.

It is understood that the third area 107 may be, but is not limited to, an area of the electronic device 10 contacted by an index finger of the user holding the electronic device 10, for example, the third area 107 may be an area contacted by a right index finger of the user holding the electronic device 10; for another example, by changing the arrangement directions of the first frame 101 and the second frame 102, the third region 107 can also be a region touched by the index finger of the left hand when the user holds the electronic device 10 with the left hand.

It is understood that the processor 130 may also determine whether the electronic device 10 is in the first-handed state and may further determine whether the electronic device 10 is in the first-handed state or the second-handed state based on the parameter values detected by the first SAR sensor 111, the second SAR sensor 112, and the third SAR sensor 114.

For example, the processor 130 may determine that the electronic device 10 is in the free state when the parameter difference detected by the first SAR sensor 111 and the second SAR sensor 112 is not greater than the first preset value, or the parameter difference detected by the first SAR sensor 111 and the second SAR sensor 112 is not greater than the first preset value and the parameter detected by the third SAR sensor 114 is less than the third preset value. For another example, the processor 130 may determine that the electronic device 10 is in the first head-hand state, for example, the right head-hand state, when the difference between the parameters detected by the first SAR sensor 111 and the second SAR sensor 112 is greater than the first preset value and the parameter detected by the third SAR sensor 114 is greater than the second preset value. For another example, the processor 130 may determine that the electronic device 10 is in the second head-hand state, for example, the left head-hand state, when the difference between the parameters detected by the first SAR sensor 111 and the second SAR sensor 112 is greater than the first preset value and the parameter detected by the third SAR sensor 114 is less than the third preset value. It can be understood that the third preset value may be the same as the second preset value, and the third preset value may also be smaller than the second preset value, which is not limited in this application.

For example, referring to fig. 9, fig. 9 is a schematic diagram illustrating the electronic device 10 shown in fig. 7 in a first head-hand state held by a right hand. When the third area 107 is an area of the electronic device 10 held by the right hand and touched by the index finger of the right hand, if the difference between the parameters detected by the first SAR sensor 111 and the second SAR sensor 112 is greater than the first preset value, it may be determined that the electronic device 10 is in the first-handed state, and at this time, if the parameter detected by the third SAR sensor 114 is greater than the second preset value, it may further indicate that the electronic device 10 is in the first-handed state, for example, the right-handed state. Referring to fig. 10, fig. 10 is a schematic diagram illustrating that the electronic device 10 shown in fig. 7 is in a second head-hand state of being held by the left hand, if the difference between the parameters detected by the first SAR sensor 111 and the second SAR sensor 112 is greater than the first preset value, the electronic device 10 may be in the head-hand state, and at this time, if the parameter detected by the third SAR sensor 114 is less than the third preset value, the electronic device 10 may be further indicated to be in the second head-hand state, for example, the left head-hand state.

It can be understood from the foregoing description that, according to the magnitude of the detection parameter of the first SAR sensor 111 and the second SAR sensor 112, it can be determined whether the electronic device 10 is in the head-hand state, or it can be preliminarily determined whether the electronic device 10 is in the left-head-hand state or the right-head-hand state. At this time, in combination with the parameter value detected by the third SAR inductor 114, it may be further verified whether the determination of the left-head-hand state or the right-head-hand state is accurate, so that the determination of the current state of the electronic device 10 in the embodiment of the present application is more accurate.

It can be understood that, if the states determined by the first SAR inductor 111 and the second SAR inductor 112 conflict with the states determined by the third SAR inductor 114, the data of the three inductors may be collected again for re-determination, or the state of the electronic device 10 may be determined according to the inductor with the largest measured value among the first SAR inductor 111, the second SAR inductor 112, and the third SAR inductor. This is not limited in the embodiments of the present application.

According to the electronic device 10 provided by the embodiment of the application, the current state of the electronic device 10 is determined according to the three SAR sensors, so that the applicable scenes of the electronic device 10, including but not limited to the left head hand state, the right head hand state and the game hand scene, can be accurately identified, and the determination of the current state of the electronic device 10 is more accurate. The electronic device 10 according to the embodiment of the present application may invoke different switching logics according to different current states thereof, so as to implement different antenna tuning, and also implement different antenna control.

Wherein the antenna device 120 may implement a wireless communication function of the electronic device 10. For example, the antenna device 120 may transmit Wi-Fi signals, global Positioning System (GPS) signals, 3rd-Generation (3G), 4th-Generation (4G), 5th-Generation (5G), near Field Communication (NFC) signals, bluetooth (BT) signals, ultra Wide Band (UWB) signals, and the like. Referring to fig. 11, fig. 11 is a schematic structural diagram of an antenna device 120 of an electronic device 10 according to an embodiment of the present disclosure. The antenna device 120 of the embodiment of the present application may include a first feed 121, a first radiator 122, a second radiator 123, and a second feed 124.

The first radiator 122 includes a first end 1221 and a second end 1222, the first end 1221 and the second end 1222 may be disposed opposite to each other, and the second end 1222 may be directly or indirectly electrically connected to a ground system to implement grounding. It will be appreciated that the ground system may be a common ground, and the ground system may be a plane or structure with zero potential. The first radiator 122 may be provided with a first feeding point 1223, the first feed 121 may be electrically connected to the first feeding point 1223 directly or indirectly to achieve electrical connection with the first radiator 122, and the first feed 121 may provide a first excitation current. The second radiator 123 may include a third end 1231 and a fourth end 1232, where a gap 108 is disposed between the third end 1231 and the first end 1221, so that the third end 1231 may be spaced apart from the first end 1221, and the fourth end 1232 may extend toward a direction away from the first radiator 122. The second radiator 123 may have a grounding point 1233, the grounding point 1233 may be located between the third end 1231 and the fourth end 1232, for example, the distance between the grounding point 1233 and the third end 1231 may be smaller than the distance between the grounding point 1233 and the fourth end 1232, so that the grounding point 1233 may be disposed near the third end 1231, and the grounding point 1233 may be directly or indirectly electrically connected to a ground system to achieve grounding.

The first excitation current provided by the first feed 121 may flow on the first radiator 122 to excite the first radiator 122 to support the wireless signal of the first frequency band, or the first excitation current may be electromagnetically coupled to the second radiator 123 and return to the ground from the ground point 1233 to excite the first radiator 122 and the second radiator 123 between the third end 1231 and the ground point 1233 to support the wireless signal of the first frequency band together. The first frequency band may be, but is not limited to, a medium-high frequency band, and the first feed 121 may excite the first radiator 122 or the first radiator 122 and a portion of the second radiator 123 may jointly support a wireless signal of the medium-high frequency band. Of course, the first frequency band may also be other frequency bands, which is not limited in this application.

The second radiator 123 may further include a second feeding point 1234, the second feeding point 1234 may be disposed between the grounding point 1233 and the fourth end 1232, and the second feed 124 may be electrically connected to the second feeding point 1234 directly or indirectly, so that the second feed 124 may be electrically connected to the second radiator 123 between the grounding point 1233 and the fourth end 1232. The second feed 124 may provide a second driving current, which may drive the second radiator 123 to support wireless signals of a second frequency band. The second frequency band may be, but is not limited to, a low frequency band, and the second feed 124 may excite the second radiator 123 to support wireless signals of the low frequency band. Of course, the second frequency band may also be other frequency bands, which is not limited in this application.

In the antenna device 120 according to the embodiment of the application, the first feed 121 may excite the first radiator 122 or the first radiator 122 and a part of the second radiator 123 support the wireless signal in the first frequency band together, and the second feed 124 may excite the second radiator 123 to support the wireless signal in the second frequency band, so that multiplexing of a part of the second radiator 123 may be achieved, and the antenna device 120 may be designed in a small size. Meanwhile, the second feed 124 is electrically connected to the region from the ground point 1233 to the fourth end 1232, the first excitation current electromagnetically coupled to the second radiator 123 can return to the ground from the ground point 1233 without causing interference to the second feed 124, and the interference between the first frequency band and the second frequency band is small.

Referring to fig. 12 in conjunction with fig. 11, fig. 12 is a fifth structural schematic diagram of the electronic device 10 according to the embodiment of the present disclosure. The first radiator 122 may be disposed opposite to the second frame 102, and the second radiator 123 between the third end 1231 and the ground point 1233 may be disposed opposite to the second frame 102. In this case, when the antenna device 120 supports the first frequency band, the main radiation section thereof may be concentrated on the second frame 102, and the main radiation direction (e.g., the second main radiation direction) of the antenna device 120 may be concentrated on the second frame 102 without being biased to the first frame 101 or the third frame 103.

It is understood that, as shown in fig. 12, the area from the ground point 1233 of the second radiator 123 to the second feeding point 1234 may also be disposed relative to the second bezel 102, and the area from the second feeding point 1234 to the fourth end 1232 is disposed relative to the third bezel 103, so that a part of the second radiator 123 may be disposed relative to the second bezel 102, and another part of the second radiator 123 may be disposed relative to the third bezel 103. When the electronic device 10 is in a free state, since the second radiator 123 has a radiator region disposed opposite to the third frame 103, a main radiation direction (e.g., the first main radiation direction) of the antenna device 120 may deviate from a direction of the centerline L0 of the second frame 102, for example, may face a direction of the third frame 103.

It can be understood that the arrangement of the first radiator 122 relative to the second frame 102 means that the first radiator 122 is formed on the second frame 102, that the first radiator 122 is connected to the second frame 102 and a projection of the first radiator 122 on the second frame 102 is located on the second frame 102, and that the first radiator 122 is spaced apart from the second frame 102 and a projection of the first radiator 122 on the second frame 102 is located on the second frame 102. Similarly, a part of the second radiator 123 is disposed opposite to the second frame 102, and another part of the second radiator 123 is disposed opposite to the third frame 103, which also means that the second radiator 123 is formed on, connected to, or spaced apart from the second frame 102 and the third frame 103, and this is not limited in this embodiment of the application.

It can be understood that, when the second radiator 123 supports the low frequency band, and the first radiator 122 or the first radiator 122 and a part of the second radiator 123 support the medium-high frequency band, the length of the branch of the second radiator 123 may be relatively longer, and the length of the branch of the first radiator 122 may be relatively shorter. For example, the length of the first radiator 122 may be about 26.7 mm, the length of the second radiator 123 may be about 78.4 mm, wherein the length from the third end 1231 to the ground point 1233 may be about 14.8 mm, and the length from the ground point 1233 to the feeding point may be about 14.8 mm.

It can be understood that when the antenna device 120 is disposed on the electronic device 10 as shown in fig. 12 (fig. 12 is a back view of the electronic device 10), the electronic device 10 may determine that the electronic device 10 is in a first head state (right head state) held by a right hand of a user according to the first SAR inductor and the second SAR inductor, or according to the first SAR inductor, the second SAR inductor, and the third SAR inductor, and in the first head state, the right hand of the user may hold at least a part of the first radiator 122 with a high probability, and at this time, the processor 130 may control the antenna device 120 to adjust a main radiation direction of the antenna device 120, and make the antenna device 120 have a second main radiation direction.

It can be understood that when the antenna device 120 is disposed on the electronic device 10 as shown in fig. 12, the electronic device 10 may determine that the electronic device 10 is in a second head-hand state (left head-hand state) held by the left hand of the user according to the first SAR inductor and the second SAR inductor, or according to the first SAR inductor, the second SAR inductor, and the third SAR inductor, where at least a part of the second radiator 123 may be held by the right hand of the user with a high probability. When the first radiator 122 or the first radiator 122 and a part of the second radiator 123 support the medium-high frequency band, the radiation performance of the medium-high frequency band is not attenuated much, so the processor may not adjust the main radiation direction of the antenna device 120, and the antenna device 120 may maintain the current state.

Referring to fig. 11 and 12 again, the antenna device 120 may further include a first adjusting circuit 125, and the grounding point 1233 may be grounded through the first adjusting circuit 125. The second radiator 123 may be multiplexed as the second SAR inductor 112.

It is understood that the first adjusting circuit 125 may include, but is not limited to, electronic devices such as capacitors, inductors, etc., one end of the first adjusting circuit 125 may be electrically connected to the ground 1233, and the other end of the first adjusting circuit 125 may be electrically connected to the ground system, so that the second radiator 123 may be grounded through the first adjusting circuit 125 having a certain impedance and not directly grounded, and the second radiator 123 may be in a "floating" state. When the second radiator 123 is multiplexed as the second SAR inductor 112, the second radiator 123 is less affected by the ground system, and the detection sensitivity of the second radiator 123 as the second SAR inductor 112 is better.

It is understood that when the first radiator 122 is in the "floating" state by the adjusting circuit, the first radiator 122 may also be multiplexed as the SAR inductor, for example, but not limited to, the first radiator 122 may be multiplexed as the first SAR inductor 111. This is not limited in the embodiments of the present application.

The second radiator 123 in the embodiment of the application is multiplexed as the second SAR inductor 112, and because the length of the second radiator 123 is longer, the area that the second radiator 123 can sense is larger, and the sensing sensitivity of the second radiator 123 as the second SAR inductor 112 is better.

As shown in fig. 11 and 12, the first adjusting circuit 125 may also adjust the frequency of the first frequency band or the second frequency band.

For example, the first adjusting circuit 125 may include a selection switch and a plurality of adjusting branches with different capacitances and inductances, one end of each adjusting branch may be electrically connected to the ground 1233 through the selection switch, another end of each adjusting circuit may be grounded, and the processor 130 may control the selection switch to select different adjusting branches to be grounded, so that the first adjusting circuit 125 may adjust the frequency of the first frequency band or the second frequency band, and the antenna device 120 may cover the first frequency band with a wider width and may also cover the second frequency band with a wider width.

It should be noted that, the above is merely an exemplary example of the first adjusting circuit 125, and the first adjusting circuit 125 may also have other structures, for example, but not limited to, it may include a band-pass band-stop circuit, and the specific structure of the first adjusting circuit 125 is not limited in this embodiment of the application.

The second adjusting circuit 127 may include, but is not limited to, capacitors, resistors, and other electronic devices, and the second adjusting circuit 127 may change the current direction and the radiation direction of the antenna device 120.

For example, when the electronic device 10 is in the free state, the first switch 126 may be in the off state, the antenna device 120 may not pass through the second adjusting circuit 127, the second adjusting circuit 127 may not change the current direction and the radiation direction of the antenna device 120, the first exciting current may still excite the first radiator 122 or the first radiator 122 and a portion of the second radiator 123 may support the first frequency band, the second exciting current may still excite the second radiator 123 to support the second frequency band, and the antenna device 120 may have the first main radiation direction.

For example, when the electronic device 10 is in the head-to-hand state, the first switch 126 may turn on the second radiator 123 and the second adjusting circuit 127, and the second radiator 123 may return to the ground through the second adjusting circuit 127, at this time, the first excitation current may still return to the ground from the first radiator 122, or return to the ground from the ground point 1233 of the second radiator 123; the second excitation current may return to the ground from the second adjusting circuit 127 or the ground point 1233, the second radiator 123 may mainly support transmission of the wireless signal through the radiation section between the third end 1231 and the ground point 1233 or the radiation section between the third end 1231 and the second adjusting circuit 127, and the first excitation current and the second excitation current may mainly flow between the first radiator 122 and the second end 1231 arranged opposite to the second frame 102 and the second radiator 123 arranged between the second adjusting circuit 127 and the third end 1231, so that the second main radiation direction of the antenna device 120 may be concentrated on the space where the central line L0 of the second frame 102 is located, and is not prone to be deviated to the first frame 101 or the third frame 103, the main radiation direction of the antenna device 120 is not prone to be held by a user's hand, and accordingly, the influence of the left or right head hand on the antenna performance may be reduced.

The antenna device 120 of the embodiment of the application changes the distribution and the radiation direction of the excitation current through the second adjusting circuit 127, so that the antenna device 120 has a radiation direction that is not easy to be held by a user, and the antenna device 120 can be ensured to have a better radiation direction in a holding state.

It is understood that the first matching circuit 128 may also adjust the frequency of the first frequency band, for example, but not limited to, a plurality of matching branches may also be disposed inside the first matching circuit 128, and the antenna device 120 may select different matching branches to adjust the frequency of the wireless signals supported by the first radiator 122 or the first radiator 122 and a portion of the second radiator 123, so that the first frequency band may cover a wider frequency band.

Similarly, the second matching circuit 129 may further adjust the frequency of the second frequency band, for example, but not limited to, multiple matching branches may also be disposed inside the second matching circuit 129, and the antenna device 120 may select different matching branches to adjust the frequency of the wireless signal supported by the second radiator 123, so that the second frequency band may cover a wider frequency band.
