[0059] Next, the embodiments in the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0060] Without departing from the spirit or scope of the present application, various modifications and changes can be made in the present application, which is obvious to those skilled in the art. Therefore, the present application is intended to cover the modifications and changes of the present application that fall within the scope of the corresponding claims (the claimed technical solutions) and their equivalents. It should be noted that the implementation manners provided by the embodiments of the present application can be combined with each other without contradiction.

[0061] To make the above objects, features, and advantages of the present application more obvious and understandable, the present application will be further described in detail below in conjunction with the drawings and specific implementation manners.

[0062] As described in the background art section, how to improve antenna performance has become a research hotspot for those skilled in the art.

[0063] In view of this, an embodiment of the present application provides an antenna module, as Figure 1 shown, the antenna module includes:

[0064] A metal housing 10 for providing an accommodation space for the antenna module;

[0065] A slot structure 20 disposed at the edge of the metal housing 10;

[0066] An antenna radiator 30, disposed in the slot structure 20 and coplanar with the slot structure 20 in at least one plane;

[0067] A feeding circuit (not shown in the figure), electrically connected to the antenna radiator 30 and capable of coupling and feeding power to the slot structure 20 through the antenna radiator 30, so as to transmit and receive target radiation signals through the antenna radiator 30 and the slot structure 20.

[0068] It should be noted that in the embodiments of the present application, if the thickness of the antenna radiator matches the thickness of the metal housing, the antenna radiator is located in the slot structure, and both opposite surfaces of the antenna radiator are coplanar with the slot structure; if the thickness of the antenna radiator is less than the thickness of the metal housing, the antenna radiator is entirely located in the slot structure, and one side surface of the antenna radiator is coplanar with the slot structure, and the other surface is not coplanar with the slot structure; if the thickness of the antenna radiator is greater than the thickness of the antenna radiator, the antenna radiator is partially located in the slot structure, and one side surface of the antenna radiator is coplanar with the slot structure, and the other surface is not coplanar with the slot structure. The present application does not limit this, as long as the antenna radiator is disposed in the slot structure and is coplanar with the slot structure in at least one plane.

[0069] Optionally, in an embodiment of the present application, one side surface of the antenna radiator facing away from the accommodation space of the metal housing is coplanar with one side of the slot structure facing away from the accommodation space of the metal housing, so that the outer surface of the antenna module is a flat surface, improving the visual experience of the appearance of the antenna module.

[0070] Optionally, in an embodiment of the present application, the slot structure may be located at the left edge of the metal housing, or at the front edge of the metal housing, or at other edge positions of the metal housing. The present application does not limit this, and it depends on the specific situation.

[0071] It should be noted that in this embodiment, the slot structure may be a T-shaped slot, or a straight slot, or a slot of other shapes. The present application does not limit this, and it depends on the specific situation. Similarly, the antenna radiator may be a T-shaped radiator, or a straight radiator, or a radiator of other shapes. The present application does not limit this, as long as at least part of the radiator is located in the slot structure.

[0072] In the antenna module provided by the embodiment of the present application, the feeding circuit transmits and receives a target radiation signal through the antenna radiator and the slot structure, and the antenna radiator and the slot structure are arranged coplanarly in at least one plane, so that when the antenna radiator transmits and receives the target radiation signal, there is no occlusion, thereby improving the antenna performance when the antenna module transmits and receives the target radiation signal.

[0073] It should be noted that in this embodiment, the feeding circuit couples and feeds power to the slot structure through the antenna radiator, which can enable the slot structure to form a slot antenna for realizing the transmission and reception of the target radiation signal. Optionally, in this embodiment, the frequency band of the radiation signal radiated and transmitted by the antenna radiator and the frequency band of the radiation signal transmitted by the slot structure may be the same to increase the communication ability of the antenna module for radio frequency signals in this frequency band, or they may be different to increase the antenna frequency band range that the antenna module can cover. The present application does not make any limitations on this, and it depends on the specific usage requirements of the antenna module.

[0074] Optionally, in an embodiment of the present application, when the frequency band of the target radiation signal radiated and received by the antenna radiator is different from the frequency band of the target radiation signal transmitted and received by the slot structure, the antenna module transmits and receives a first radiation signal through the antenna radiator, and couples and feeds power between the antenna radiator and the slot structure to transmit a second radiation signal through the slot structure, and the second radiation signal is different from the first radiation signal.

[0075] Optionally, in an embodiment of the present application, the frequency of the first radiation signal transmitted and received by the slot structure is lower than the frequency of the second radiation signal transmitted and received by the antenna radiator. For example, the slot structure is used to transmit and receive low-frequency signals, and the antenna radiator is used to transmit and receive high-frequency signals. However, the present application does not make any limitations on this, and it depends on the specific situation.

[0076] Optionally, in an embodiment of the present application, continuing as Figure 1 shown, the metal housing 10 includes a first housing 11, the slot structure 20 includes a first slot 21 arranged along the extension direction of the first edge of the first housing 11, and the antenna radiator 30 includes a radiation branch 31 arranged along the extension direction of the first slot 21. Specifically, in this embodiment, the first slot 21 has a second edge and a third edge arranged oppositely, and the extension directions of the second edge and the third edge are parallel to the extension direction of the first edge.

[0077] On the basis of the above embodiment, in an embodiment of the present application, continuing as Figure 1As shown, the spacing between the radiation branches 31 of the antenna radiator 30 and the second edge and the third edge is different, i.e., D1≠D2, so as to adjust the bandwidth of the antenna module by adjusting the distances between the radiation branches of the antenna radiation and the second edge and the third edge.

[0078] It should be noted that the spacing between the radiation branches of the antenna radiator and the second edge and the third edge will also affect the coupling efficiency between the antenna radiator and the slot structure. Specifically: the smaller the spacing between one of the second edge and the third edge close to the feed point position of the antenna radiator and the antenna radiator, the higher the signal coupling efficiency between the antenna radiator and the slot structure.

[0079] Optionally, in an embodiment of the present application, the feed point position of the antenna radiator is located on the side of the radiation branch close to the second edge, and the first spacing between the radiation branch of the antenna radiator and the second edge is less than the second spacing between the radiation branch of the antenna radiator and the third edge, so as to improve the coupling efficiency between the radiation branch of the antenna radiator and the second edge of the slot structure, thereby improving the signal quality of the target radiation signal received and transmitted by the slot structure.

[0080] It should be noted that in the above embodiment, the spacing between the second edge and the first edge is less than the spacing between the third edge and the first edge. That is, in this embodiment, the second edge is the side of the slot structure close to the first edge of the first housing, and the third edge is the side of the slot structure away from the first edge of the first housing. Optionally, in an embodiment of the present application, as Figure 2 shown, the second edge may be the same edge as the first edge, or the second edge is a partial area of the first edge, so that the slot structure is arranged next to the first edge of the first housing, but the present application does not limit this. In other embodiments of the present application, there may also be a gap between the second edge and the first edge. Continuing as Figure 1 shown, it depends on the specific situation.

[0081] In another embodiment of the present application, the feeding point position of the antenna radiator is located on the side of the radiation branch near the third edge. The first spacing between the radiation branch of the antenna radiator and the second edge may also be greater than the second spacing between the radiation branch of the antenna radiator and the electrical edge, so as to improve the coupling efficiency between the radiation branch of the antenna radiator and the third edge of the slot structure, thereby improving the signal quality of the target radiation signal received and transmitted by the slot structure. In other embodiments of the present application, the spacing between the radiation branch of the antenna radiator and the second edge and the third edge may also be the same, and the present application does not limit this, which depends on the specific situation.

[0082] Optionally, in an embodiment of the present application, the first spacing is not greater than 2 mm, and the second spacing is not greater than 2 mm, but the present application does not limit this, which depends on the specific situation.

[0083] Taking the second edge may be the same edge as the first edge, or the second edge is a partial area of the first edge as an example, the antenna module provided by the embodiments of the present application will be described below.

[0084] Based on any of the above embodiments, in an embodiment of the present application, the first slot has a fourth edge and a fifth edge arranged oppositely, and the extending directions of the fourth edge and the fifth edge are perpendicular to the extending direction of the first edge. Optionally, in this embodiment, continue as Figure 1 shown, the spacing between the radiation branch of the antenna radiator and the fourth edge and the fifth edge may be different, that is, H1≠H2, or may be the same, that is, H1 = H2, which depends on the application requirements of the antenna module. It should be noted that in specific applications, the antenna module can adjust the frequency offset of the radiation signal received and transmitted by the slot structure through the spacing between the radiation branch of the antenna radiator and the fourth edge and the fifth edge, so that the actually received and transmitted radiation signal of the slot structure matches the first radiation signal.

[0085] Optionally, in an embodiment of the present application, as Figure 3As shown, the antenna radiator includes a first radiation branch 311 and a second radiation branch 312 that are spaced apart along the extension direction of the first slot 21. However, the present application does not limit this. In other embodiments of the present application, the first radiation branch 311 and the second radiation branch 312 may also be connected, depending on the specific situation. Among them, the first radiation branch 311 is used to transmit and receive a first sub-radiation signal, and the second radiation branch 312 is used to transmit and receive a second sub-radiation signal. The first sub-radiation signal and the second sub-radiation signal may be the same to increase the signal throughput of the frequency band corresponding to the first sub-radiation signal, or may be different to increase the bandwidth of the first radiation signal transmitted and received by the antenna radiator.

[0086] Based on the above embodiments, in an embodiment of the present application, the length of the first radiation branch in the extension direction is different from the length of the second radiation branch in the extension direction, so that the radiation signals transmitted and received by the first radiation branch and the second radiation branch are different.

[0087] It should be noted that the longer the length of the first radiation branch in its extension direction, the lower the frequency band of the radiation signal transmitted and received by the first radiation branch. Conversely, the shorter the length of the first radiation branch in its extension direction, the higher the frequency band of the radiation signal transmitted and received by the first radiation branch. Similarly, the longer the length of the second radiation branch in its extension direction, the lower the frequency band of the radiation signal transmitted and received by the second radiation branch. Conversely, the shorter the length of the second radiation branch in its extension direction, the higher the frequency band of the radiation signal transmitted and received by the first radiation branch. Optionally, the length of the first radiation branch in the extension direction is greater than the length of the second radiation branch in the extension direction, so that the frequency band of the radiation signal transmitted by the first radiation branch is lower than the frequency band of the radiation signal transmitted by the second radiation branch. For example, the first radiation branch is used to transmit and receive 2.4G frequency band signals, and the second radiation branch is used to transmit and receive 5G, 6G or 7G frequency band signals. The present application does not limit this, depending on the specific situation.

[0088] It should be noted that the length of a typical resonant dipole is half of the wavelength (λ / 2) corresponding to the center frequency of the radiation signal it transmits and receives. This length is beneficial for antenna radiation. Moreover, the excitation RF energy source applied in the middle of the conductor length is a voltage source, and the voltage output by the voltage source is a sinusoidal voltage. The generated radio frequency electric field can make one end of the λ / 2 long wire have a negative potential and the other end have a positive potential, and the current (charge) starts to flow from one end of the conductor to the other end.

[0089] In this embodiment, radiation branches of an antenna radiator are disposed in the slot structure, and the radiation branches are conductors. Therefore, the antenna module provided by the embodiment of the present application can form a resonant dipole antenna. Optionally, in an embodiment of the present application, continue as Figure 3 shown, the feeding circuit includes a first feed source 41, the first feed source 41 is disposed at an intermediate position in the extending direction of the first slot 21, the first radiation branch 311 and the second radiation branch 312 extend from the intermediate position in directions away from each other, and the first feed source 41 can excite the first radiation branch 311 and the second radiation branch 312 to generate excitation currents in the same direction to form a resonant dipole antenna.

[0090] Based on the above embodiment, in an embodiment of the present application, continue as Figure 3 shown, the length L1 of the first radiation branch 311 in its extending direction is the same as the length L2 of the second radiation branch 312 in its extending direction, and the length of the radiation branch of the antenna radiator in the extending direction along the first edge is λ / 2, that is, the overall length of the first radiation branch 311 and the second radiation branch 312 in the extending direction along the first edge 21 is λ / 2, that is, L1 + L2 = λ / 2, so that the charge (or current) in the radiation branch is transmitted from the first end of the radiation branch to the second end opposite to the first end, such as from the end of the first radiation branch 311 far from the second radiation branch 312 to the end of the second radiation branch 312 far from the first radiation branch 311 (or from the end of the second radiation branch 312 far from the first radiation branch 311 to the end of the first radiation branch 311 far from the second radiation branch 312). In this process, if the charge is transmitted at the speed of light, the time for the charge (or current) in the radiation branch to be transmitted from the first end of the radiation branch to the second end is equal to 1 / 2 of the period duration of the excitation frequency of the first feed source.

[0091] When the charge (or current) in the radiation branch is transmitted from the first end of the radiation branch to the second end, the first feed source completes its 1 / 2 period and reverses its phase, so that the voltage polarities at both ends of the radiation branch change, thereby forcing the current direction on the λ / 2 length of the dipole to reverse. This process is repeated, so that the current direction on the radiation branch reverses infinitely, so that the charge (current) oscillates back and forth continuously along the length of the radiation branch to form an oscillating radiation wave.

[0092] It should be noted that, in this embodiment, although the ends of the radiation stubs are open, that is, the end of the first radiation stub far from the second radiation stub and the end of the second radiation stub far from the first radiation stub are open, and a necessary condition for current flow in the traditional sense - a closed circuit - is not formed, the middle and high frequency bands of the WIFI antenna can be covered by adjusting the lengths of the radiation stubs in the slot structure.

[0093] As Figure 4 shown, based on any of the above embodiments, in an embodiment of the present application, the metal housing 10 further includes a second housing 12 connected to the first edge of the first housing 11, and the slot structure 20 further includes a second slot 22 disposed on the second housing 12. The second slot 22 communicates with the first slot 21 so that the slot structure 20 can form a T-shaped slot or a quasi-T-shaped slot. It should be noted that, in this embodiment, when the extending directions of the first slot 21 and the second slot 22 are perpendicular, the slot structure 20 forms a T-shaped slot, and when the angle between the extending directions of the first slot and the second slot is greater than 0° and less than 90°, the slot structure forms a quasi-T-shaped slot.

[0094] Based on the above embodiments, in an embodiment of the present application, the connection position of the second slot and the first slot is located in the middle region of the first slot in the extending direction. The widths of the second slot and the first slot may be the same or different, and the present application does not limit this, which depends on the specific situation.

[0095] Optionally, in an embodiment of the present application, as Figure 5 shown, the antenna radiator further includes a third radiation stub 313 and a fourth radiation stub 314 disposed along the extending direction of the second slot 22. The third radiation stub 313 is connected to the first radiation stub 311, and the fourth radiation stub 314 is connected to the second radiation stub 312. Optionally, in an embodiment of the present application, the third radiation stub 313 and the fourth radiation stub 314 are spaced apart in a direction perpendicular to the extending direction of the second slot 22, and the first radiation stub 311 and the second radiation stub 312 are spaced apart in a direction parallel to the extending direction of the first slot 21, so that the fourth radiation stub 314 and the second radiation stub 312 form an L-shaped antenna, and the third radiation stub 313 and the first radiation stub 311 form an L-shaped antenna.

[0096] Based on the above embodiments, in an embodiment of the present application, continue as Figure 5As shown, the feeding circuit includes a second feed source 42, which is connected to the first end of the third radiation branch 313 and the second end of the fourth radiation branch 314, and the second feed source 42 can excite the third radiation branch 313, the first radiation branch 311, the fourth radiation branch 314, and the second radiation branch 312 to generate excitation currents in the same direction so as to receive and send target radiation signals through the radiation branches; wherein the first end is the end of the third radiation branch 313 away from the first radiation branch 311, and the second end is the end of the fourth radiation branch 314 away from the second radiation branch 312. Optionally, in this embodiment, the length of the first radiation branch along its extension direction is the same as the length of the second radiation branch along its extension direction, and the length of the first radiation branch along its extension direction and the length of the second radiation branch along its extension direction are λ / 2, that is, the overall length of the first radiation branch and the second radiation branch along the extension direction of the first edge is λ / 2, so that the charge (or current) in the radiation branch is transmitted from the first end of the radiation branch to the second end opposite to the first end, such as from the end of the first radiation branch away from the second radiation branch to the end of the second radiation branch away from the first radiation branch (or from the end of the second radiation branch away from the first radiation branch to the end of the first radiation branch away from the second radiation branch), and when the charge (or current) in the radiation branch is transmitted from the first end to the second end of the radiation branch, the second feed source completes its 1 / 2 cycle and reverses the phase, so that the voltage polarity at both ends of the radiation branch changes, thereby forcing the current direction on the λ / 2 length of the dipole to reverse. This process repeats itself in this way, causing the direction of the current on the radiating branch to reverse repeatedly indefinitely, so that the charge (current) oscillates back and forth along the length of the radiating branch, forming an oscillating radiation wave.

[0097] It should be noted that, in the antenna module provided in the embodiment of the present application, the antenna radiator is at least partially located in the slot structure. In specific applications, the frequency band performance requirements required by the coverage antenna module can be met by adjusting the distance between the radiating branches of the antenna radiator and the second edge and the third edge of the first slot, the length and width of the first slot itself, and the length and width of the radiating branches in the antenna radiator, and combining the actual environmental adjustment of the entire machine.

[0098] Specifically, in one embodiment of the present application, the low frequency band in the WiFi antenna of the antenna module is transmitted and received by the slot structure, and the high frequency band is transmitted and received by the antenna radiator.

[0099] It should be noted that a slot antenna refers to a long resonant slot opened on the shell wall. If the opened slot cuts off the conduction current on the shell, an electric field will be generated on the shell slot, which will disturb the current on the inner wall of the shell and couple part of the electromagnetic energy from the shell into the outer space for radiation. Such a slot is called a radiation slot, and the radiation slot is a narrow slot, that is, the aspect ratio is much greater than 1.

[0100] It should also be noted that when the length of the radiation slot is half a wavelength, only the main mode TE10 mode is transmitted in the shell, while the low-frequency antenna frequency and is applicable to the waveguide wall thickness approaching 0 and being an ideal conductor. However, the metal shell has a certain thickness. Therefore, the slot length of the radiation slot for transmitting and receiving low-frequency radiation signals is generally less than

[0101] Optionally, in an embodiment of the present application, the thickness of the metal shell is 0.8 mm.

Optionally, the extending direction of the second edge is parallel to the extending direction of the first edge, and the second edge and the first edge are two opposite edges of the first housing.

[0106] Specifically, in an embodiment of the present application, as Figure 9 shown, the electronic device includes:

[0107] A device body 101, where the device body 101 includes an accommodation space composed of a metal housing;

[0108] An antenna module and a first communication module disposed in the accommodation space, the antenna module comprising:

[0109] A slot structure 20 disposed at the edge of the metal housing; an antenna radiator 30, at least part of the antenna radiator 30 is located in the slot structure 20 and is coplanar with the slot structure 20 in at least one plane; a feeding circuit 40, the feeding circuit 40 is electrically connected to the antenna radiator 30 and can couple-feed the slot structure 20 through the antenna radiator 30, so as to transmit and receive target radiation signals for the first communication module through the antenna radiator 30 and the slot structure 20.

[0110] Optionally, in the embodiment of the present application, the edge of the metal housing where the slot structure is disposed can be the left edge of the metal housing, or the front edge of the metal housing, or other edge positions of the metal housing. The present application does not limit this, and it depends on the specific situation.

[0111] It should be noted that, in this embodiment, the slot structure can be a T-shaped slot, or a straight slot, or a slot of other shapes. The present application does not limit this, and it depends on the specific situation. Similarly, the antenna radiator can be a T-shaped radiator, or a straight radiator, or a radiator of other shapes. The present application does not limit this, as long as at least part of the radiator is located in the slot structure.

[0112] It should also be noted that, in this embodiment, if the thickness of the antenna radiator matches the thickness of the metal housing, the antenna radiator is located in the slot structure, and both opposite surfaces of the antenna radiator are coplanar with the slot structure; if the thickness of the antenna radiator is less than the thickness of the metal housing, the antenna radiator is entirely located in the slot structure, and one surface of the antenna radiator is coplanar with the slot structure, and the other surface is not coplanar with the slot structure; if the thickness of the antenna radiator is greater than the thickness of the antenna radiator, part of the antenna radiator is located in the slot structure, and one surface of the antenna radiator is coplanar with the slot structure, and the other surface is not coplanar with the slot structure. The present application does not limit this, as long as the antenna radiator is disposed in the slot structure and is coplanar with the slot structure in at least one plane.

[0113] Optionally, in an embodiment of the present application, the antenna radiator may be coplanar with the A surface of the electronic device, or may be coplanar with the D surface of the electronic device. The present application does not limit this. As long as the antenna radiator is coplanar with at least one outer surface of the electronic device, so that the antenna radiator and the outer surface of the electronic device are in the same plane.

[0114] In the antenna module of the electronic device provided by the embodiment of the present application, the feeding circuit transmits and receives the target radiation signal through the antenna radiator and the slot structure, and the antenna radiator and the slot structure are coplanar in at least one plane, so that when the antenna radiator transmits and receives the target radiation signal, there is no occlusion, thereby improving the antenna performance when the antenna module transmits and receives the target radiation signal.

[0115] Since the relevant content of the antenna module has been described in detail in the above embodiments, the present application will not elaborate herein.

[0116] It should be noted that with the development of communication technology, users' requirements for the transmission rate of electronic devices are constantly increasing. For example, the demands for audio and video, games, high-definition real-time video communication, etc. are increasing. At the same time, with the design trends of electronic devices such as thin and light, all-metal and full-screen appearance, high screen-to-body ratio, and large battery capacity, the antenna design space of electronic devices has been greatly compressed. Generally speaking, the higher the power of the electromagnetic wave emitted or received by the antenna of the electronic device, the better the Over The Air (OTA) performance. However, electromagnetic waves with too high power may have the risk of exceeding the Specific Absorption Ratio (SAR), and have an impact on human health. Therefore, the design of the antenna module in the electronic device not only needs to take into account the OTA performance, but also its own SAR needs to meet the FCC / CE certification requirements.

[0117] Specifically, whether the electromagnetic radiation of the electronic device meets the standard is usually evaluated by the Specific Absorption Rate (SAR). The Specific Absorption Rate refers to the electromagnetic wave energy (W) absorbed by the unit mass (kg) of biological tissue averaged by a small sample volume. When the SAR value is higher than 4 W / kg, radiation exposure may damage human health. For example, the relevant standards stipulate the SAR values of products such as wireless earphones and mobile phones as follows: the Specific Absorption Rate of 1 gram of biological tissue ≤ 1.6 W / kg, or the Specific Absorption Rate of 10 grams of biological tissue ≤ 2.0 W / kg.

[0118] Optionally, in an embodiment of the present application, as Figure 10 shown, the electronic device further includes:

[0119] A monitoring circuit 50 disposed in the accommodation space and electrically connected to the antenna radiator 30 for monitoring the specific absorption rate value of the electronic device or the relative position data between the human body and the electronic device;

[0120] A controller 60, signal - connected to the monitoring circuit 50, for controlling the operating parameters of the antenna module based on the specific absorption rate value or the relative position data.

[0121] Specifically, in this embodiment, when the monitoring circuit monitors through the antenna radiator that the specific absorption rate value of the electronic device exceeds a set threshold or the relative position data between the human body and the electronic device is less than a set distance, the controller controls the antenna module to reduce the parameters to reduce the impact of the electromagnetic wave power transmitted or received by the antenna module on the human body; when the monitoring circuit monitors through the antenna radiator that the specific absorption rate value of the electronic device is lower than the set threshold or the relative position data between the human body and the electronic device is greater than the set distance, the controller controls the antenna module to increase the parameters to increase the electromagnetic wave power transmitted or received by the antenna module and improve the antenna performance of the electronic device. It should be noted that in this embodiment, the antenna radiator is located in the gap structure and there is no obstruction outside, so that when the monitoring circuit uses the antenna radiator to monitor the specific absorption rate value of the electronic device or the relative position data between the human body and the electronic device, the metal housing will not obstruct the antenna radiator, which is beneficial to improving the accuracy and sensitivity when the monitoring circuit uses the antenna radiator to monitor the specific absorption rate value of the electronic device or the relative position data between the human body and the electronic device.

[0122] It can be seen that the electronic device provided by the embodiment of the present application can not only balance the extreme space requirements in the electronic device, meet the all - metal appearance ID, meet the OTA performance requirements, but also meet the requirements for human body radiation SAR, improving the user experience. Moreover, the antenna module and the monitoring circuit share the same antenna radiator, without the need to additionally set a conductor for monitoring whether there is someone approaching around the electronic device, so there is no need to additionally set space, which is beneficial to the miniaturization of the electronic device while improving the antenna function and realizing SAR monitoring.

[0123] In addition, for the electronic device provided by the embodiment of the present application, by setting a gap structure on the metal housing of the device body and setting an antenna radiator in the gap structure, during application, based on the system stacking requirements of the electronic device, the position of the gap structure can be flexibly set, and the design is convenient and flexible.

[0124] Optionally, in an embodiment of the present application, the electronic device further includes a memory, and the memory stores the specific absorption rate of different electronic devices and / or the radiation signal transmission power of the antenna module corresponding to different relative position data between the human body and the electronic device. However, the present application does not limit this, and it depends on the specific situation.

[0125] Optionally, in an embodiment of the present application, the monitoring circuit includes a specific absorption rate sensor or a proximity sensor disposed between the antenna radiator and the antenna ground of the antenna module. Both ends of the specific absorption rate sensor or the proximity sensor are electrically connected to the antenna radiator and the antenna ground respectively, and are used to monitor the specific absorption rate value of the electronic device or the relative position data between the human body and the electronic device. However, the present application does not limit this. In other embodiments of the present application, the monitoring circuit can also monitor the specific absorption rate value of the electronic device or the relative position data between the human body and the electronic device by other means, depending on the specific situation.

[0126] It should be noted that when a human body approaches the electronic device, the environmental capacitance around the antenna module of the electronic device changes significantly. Specifically, capacitance refers to the ability to store charge between two conductors separated by an insulating material. When the human body approaches near the antenna module of the electronic device, according to the principle of parallel plate capacitance, the change in the capacitance between the antenna radiator and the human body is proportional to the facing area and the dielectric constant between the antenna radiator and the human body, and inversely proportional to the distance between the human body and the antenna radiator. Specifically, as Figure 11 shown, the capacitance between the antenna radiator and the human body where A represents the facing area between the antenna radiator and the human body, ε r ε 0 represents the dielectric constant between the antenna radiator and the human body, and d represents the distance between the human body and the antenna radiator.

[0127] Optionally, in an embodiment of the present application, the proximity sensor includes a capacitance sensor, and the capacitance sensor detects the human touch or proximity event around the electronic device by measuring the change in the capacitance between two conductive objects (i.e., between the antenna radiator and the human body). When a conductor approaches the electronic device, it will change the electric field distribution, resulting in an increase or decrease in capacitance. Therefore, the approach and departure of the human body around the electronic device can be reflected by the change in capacitance. Under the action of an alternating current signal with a fixed frequency, the change in capacitance will cause a voltage difference. Therefore, by comparing the voltage changes caused by the known capacitance and the unknown capacitance, the change in capacitance can be measured, and thus the relative position data between the human body and the electronic device can be obtained.

[0128] Based on any of the above embodiments, in an embodiment of the present application, a signal isolation device is further provided on the signal path between the monitoring circuit and the antenna radiator to reduce the interference of the radiation signal transmitted and received by the antenna module to the signal that monitors the specific absorption rate value representing the electronic device or the relative position data between the human body and the electronic device by the monitoring circuit.

The distances between the radiation branches of the antenna radiator and the second edge and the third edge are different, so as to adjust the bandwidth of the antenna module by adjusting the distances between the radiation branches of the antenna radiation and the second edge and the third edge.

[0132] Based on the above embodiments, in an embodiment of the present application, the antenna radiator includes a first radiation branch and a second radiation branch that are spaced apart along the extension direction of the first slot. However, the present application does not limit this. In other embodiments of the present application, the first radiation branch and the second radiation branch may also be connected, depending on the specific situation. Wherein, the first radiation branch is used for transmitting and receiving a first sub-radiation signal, the second radiation branch is used for transmitting and receiving a second sub-radiation signal, and the first sub-radiation signal and the second sub-radiation signal may be the same to increase the signal throughput of the frequency band corresponding to the first sub-radiation signal, or may be different to increase the bandwidth of the first radiation signal transmitted and received by the antenna radiator.

The second slot is communicated with the first slot so that the slot structure can form a T-shaped slot or a quasi-T-shaped slot.

[0136] Based on the above embodiments, in an embodiment of the present application, the feeding circuit includes a second feed source, which is connected to the first end of the third radiation branch and the second end of the fourth radiation branch. The second feed source can excite the third radiation branch, the first radiation branch, the fourth radiation branch, and the second radiation branch to generate excitation currents in the same direction, so as to transmit and receive target radiation signals through the radiation branches.

The first edge is the edge of the first housing close to the rotating shaft assembly, that is, the first edge is an edge parallel to the edge where the first body or the second body is connected to the rotating shaft assembly. Optionally, in the embodiment of the present application, the value range of the first threshold range is 0°-180°, but the present application does not limit this, and it depends on the specific situation.

[0138] In another embodiment of the present application, the rotation angle range of the relative rotation of the first body and the second body is within a second threshold range. The first edge is the edge of the first housing far from the rotating shaft assembly, or an edge perpendicular to the rotating shaft assembly.
