a coupling part 12, the coupling part 12 being disposed in a target area at a target distance from the radiation part 11;

wherein the coupling section 12 forms a resonance of a radiation band of the radiation section 11, thereby reducing a specific absorption rate SAR in a target radiation direction of the radiation section 11.

In an embodiment of the application, the radiating element is an element for transmitting and/or receiving communication signals. The coupling member is a member provided in the electronic device for forming resonance with a radiation band in a target radiation direction of the radiation member, and generally has a metal characteristic. The coupling member may or may not be grounded. In the coupling member grounding process, the coupling member is connected to a ground circuit in a circuit board structure of the electronic device, and specifically, the coupling member may be connected to the ground circuit in the circuit board structure of the electronic device through a metal wire or another ground member.

The electronic equipment provided by the embodiment of the application carries out grounding treatment on the coupling part, so that the grounded coupling part forms resonance with the radiation frequency band of the radiation part to generate a coupling effect, thereby effectively reducing the SAR in the target radiation direction of the radiation part, solving the problem that the SAR mode of the antenna is single at present, enriching the mode of adjusting the radiation efficiency of the antenna, realizing the scheme of effectively adjusting the radiation frequency band of the antenna, reducing the SAR peak value of the antenna, and achieving the set SAR peak value standard.

Based on the foregoing embodiments, an embodiment of the present application provides an electronic device, which is shown in fig. 1 and includes:

a coupling member disposed within a target area at a target distance from the radiating member;

wherein, if the coupling part is grounded, the coupling part forms resonance of a radiation frequency band of the radiation part, thereby reducing a specific absorption rate SAR in a target radiation direction of the radiation part.

In the embodiment of the present application, the radiation component may be an antenna device for transmitting and/or receiving communication signals, and correspondingly, the coupling component may be a metal piece or a metal film-coated component itself within a target distance range from the radiation component in the electronic device, or a part of the metal piece or the metal film-coated component, wherein the metal piece or the metal film-coated component may be a decorative piece.

In other embodiments of the present application, the length of the coupling member falls within a target length range; wherein the target wavelength is a wavelength of a communication signal transmitted and/or received by the radiating element, a length of one half of the target wavelength belongs to a target length range, and/or a length of one quarter of the target wavelength belongs to a target length range.

In the embodiments of the present application, the coupling component is the trim component itself, i.e., the length of the coupling component is the length of the trim component. When the length of the decoration part is within the target length range of the half of the target wavelength and is arranged in the target area away from the radiation part, the coupling part, namely the decoration part, can be not subjected to grounding treatment, the coupling effect can be realized, and the SAR of the electronic equipment is reduced.

The length of the coupling member may be determined by the positional relationship between the ground position and the radiation member.

The target length range is a length range, and may be expressed, for example, as (λ/2- Δ 1, λ/2+ Δ 2), or (λ/4- Δ 1, λ/4+ Δ 2), where λ represents a target wavelength of a communication signal transmitted and/or received by the radiating element, λ/2 represents one half of the target wavelength, λ/4 represents one quarter of the target wavelength, both Δ 1 and Δ 2 are numbers greater than 0, both Δ 1 and Δ 2 are determined by the target wavelength, λ/2- Δ 1 is greater than 0, and λ/4- Δ 1 is greater than 0.

The installation position of the grounding member on the decorative member can be simulated by specific simulation software based on the size of the decorative member and the shape of the decorative member.

In this way, resonance is achieved between the coupling part B and the radiation part, thereby adjusting the radiation frequency of the radiation part from a first frequency to a second frequency, wherein the first frequency is greater than the second frequency.

In other embodiments of the present application, the radiating element comprises an antenna for transmitting and/or receiving a single frequency band.

In the embodiments of the present application, the antennas provided in the electronic device are of various types, including an antenna group that can transmit and/or receive communication signals of a plurality of different frequency bands, and an antenna group that can transmit and/or receive a single frequency band. In this application, the radiating element is at least one antenna group in an antenna for transmitting and/or receiving a single frequency band in the electronic device.

In this application, when the radiation frequency of the radiation component in the target radiation direction is reduced by the coupling component, the radiation power of the radiation component does not change at all, that is, the radiation power of the radiation component is kept at the target radiation power throughout the process of adjusting the radiation frequency of the radiation component in the target radiation direction from the first frequency to the second frequency.

In other embodiments of the present application, the coupling component includes at least a rear camera trim piece and/or an earpiece trim piece.

It should be noted that, for the explanation of the components in this embodiment and the same components in the above embodiments, reference may be made to the description in the above embodiments, and details are not described here.

An embodiment of the present application provides a control method, which is applied to the electronic device provided in the foregoing embodiment, and as shown in fig. 5, the method includes:

step 201, obtaining a trigger signal.

In this application embodiment, the electronic device can sense whether a human body and the like are close to the electronic device through the sensing component, and when the sensing component senses that the human body and the like are close to the electronic device, the sensing component of the electronic device generates a trigger signal.

Step 202, controlling the coupling component to be grounded based on the trigger signal.

Wherein the coupling element forms a resonance of a radiation frequency band of the radiation element so as to reduce a specific absorption rate SAR in a target radiation direction of the radiation element, the coupling element being disposed in a target region at a target distance from the radiation element.

In the embodiment of the application, the electronic device performs grounding processing on the coupling component in response to the trigger signal, so as to reduce the radiation frequency of the radiation component corresponding to the coupling component from a first frequency to a second frequency, wherein the first frequency is greater than the second frequency. The coupling component and the corresponding radiation component are arranged in the electronic equipment in advance.

In some application scenarios, in a production process of the electronic device, the coupling component may also be directly disposed within a target distance range of the radiation component, and the coupling component is grounded, so as to bring the SAR of the radiation component corresponding to the coupling component within a SAR peak value standard. Or in the production process of the electronic device, the coupling component is arranged in the target distance range of the radiation component, and the coupling component is the decoration component, namely when the length of the decoration component belongs to the target length range, the coupling component can be grounded or ungrounded, and the coupling component can also form the resonance of the radiation frequency band of the radiation component, so that the special absorption rate SAR in the target radiation direction of the radiation component is reduced, and the coupling component is arranged in the target area at the target distance from the radiation component; wherein a length of one half of a target wavelength of a communication signal transmitted and/or received by the radiating element belongs to said target length range and/or a length of one quarter of said target wavelength belongs to said target length range. In this application scenario, the grounding process of the coupling element is not controllable.

It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.

According to the control method provided by the embodiment of the application, the coupling part is grounded, so that the grounded coupling part forms resonance with the radiation frequency band of the radiation part to generate a coupling effect, the SAR in the target radiation direction of the radiation part is effectively reduced, the problem that the SAR adjusting mode of the antenna is single at present is solved, the mode of adjusting the radiation efficiency of the antenna is enriched, the scheme of effectively adjusting the radiation frequency band of the antenna is realized, the SAR peak value of the antenna is reduced, and the set SAR peak value standard is achieved.

Based on the foregoing embodiments, an embodiment of the present application provides a control method, which is applied to the electronic device provided in the foregoing embodiments, and as shown in fig. 6, the method includes:

step 301, obtaining a trigger signal.

In this embodiment of the application, the electronic device is provided with the sensing component, and the corresponding trigger signal may be obtained by detection of the sensing component in the electronic device.

The sensing component is exemplified as a capacitive Sensor (Cap Sensor), but it is needless to say that other sensors may sense that a user approaches a specific position, for example, a sensing component such as a P Sensor, an infrared Sensor, an ultrasonic Sensor, or a ToF Sensor, and if the target distance between the decorative component and the radiation component is much less than one tenth of the target wavelength, the decorative component may be directly processed, which may affect the radiation efficiency of the radiation component. Therefore, in the embodiment of the application, whether a target object such as a human body approaches the electronic device is sensed by the capacitive sensor, and if the capacitive signal of the capacitive sensor changes, the capacitive sensor sends the changed capacitive signal, i.e., the trigger signal, to the processor of the electronic device, so that the processor of the electronic device obtains the trigger signal.

Step 302, controlling the coupling component to be grounded based on the trigger signal.

Wherein, if the coupling element is grounded, the coupling element forms resonance of a radiation frequency band of the radiation element, thereby reducing a specific absorption rate SAR in a target radiation direction of the radiation element, the coupling element is disposed in a target region at a target distance from the radiation element.

In other embodiments of the present application, the length of the coupling member falls within a target length range; wherein the length of one half of the target wavelength belongs to a target length range and/or the length of one quarter of the target wavelength belongs to a target length range, the target wavelength being the wavelength of the communication signal transmitted and/or received by the radiating element.

In other embodiments of the present application, an electronic device includes: a decorative member and a ground member; wherein: after the decoration component is grounded through the grounding component, the decoration component forms a coupling component; the coupling component is a part of the decoration component which generates a coupling effect to generate resonance with a radiation frequency band of the radiation component, the length of the coupling component belongs to a target length range, the length of one half of a target wavelength belongs to the target length range, and/or the length of one quarter of the target wavelength belongs to the target length range, and the target wavelength is the wavelength of a communication signal transmitted and/or received by the radiation component.

Step 303, based on the trigger signal, adjusting the radiation power of the target radiation component from the first power to the second power.

Wherein the first power is greater than the second power, and the target radiating element is different from the radiating element.

In the embodiment of the application, the electronic device further adjusts the radiation power of a target radiation component in the electronic device, except for the radiation component, based on the trigger signal, so as to reduce the SAR of the target radiation component.

In other embodiments of the present application, when the electronic device has multiple sets of coupling components and corresponding radiation components, and each coupling component is provided with a corresponding grounding component, the electronic device determines a sensor corresponding to a trigger signal, determines at least one set of corresponding coupling components based on the sensor, and controls at least one set of coupling components corresponding to a detection position to perform grounding processing based on the trigger signal.

In other embodiments of the present application, the electronic device may further select to perform step 302 or perform step 303 according to the trigger signal. For example, a sensor for obtaining the trigger signal is determined, and if the sensor is close to the radiation component, it indicates that the human body is close to the radiation component, so step 302 is executed to reduce the SAR of the radiation component by reducing the radiation frequency of the radiation component; if the sensor is close to the target radiation element, it indicates that the human body is close to the target radiation element, and therefore, step 303 is performed to reduce the SAR of the target radiation element by reducing the radiation power of the target radiation element.

Based on the foregoing embodiments, the present application provides a control method, which is applied to a smart phone having a fifth Generation mobile communication technology (5th Generation mobile network, 5th Generation wireless systems, or 5th-Generation, abbreviated as 5G or 5G technology). In a 5G smart phone, there are usually 8 to 9 antennas, which are respectively used as Long Term Evolution (LTE) antennas for transmitting a main set universal mobile communication technology, a main set New Radio, NR (New Radio, NR) antenna, a main set NR ultrahigh frequency (NR) antenna, two 4 × 4 Multiple-Input Multiple-Output (MIMO) HB antennas, a GPS antenna, a WIFI2.4 gigahertz (GHz) antenna, a WIFI5GHz, and a WIFI2.4/5G MIMO antenna.

The main set LTE antenna is used for ensuring that the electronic equipment realizes communication of a second Generation mobile communication technology (2-Generation wireless telephone technology, 2G), a third Generation mobile communication technology (3-Generation wireless telephone technology, 3G) or a fourth Generation mobile communication technology (4-Generation wireless telephone technology, 4G) when 5G signals are incompatible while realizing 5G communication; the main set NR antenna and the main set NR ultrahigh frequency antenna are used for realizing 5G communication; the two 4-by-4 MIMO high-frequency antennas are used for receiving 4 in and 4 out high-frequency communication signals; the GPS antenna is used for receiving GPS positioning signals; the WIFI2.4 GHz is used for realizing 2.4GHz wireless communication network communication; the WIFI5GHz is used for realizing wireless communication network communication of 5 GHz; the MIMO antenna of WIFI2.4/5g is used for receiving wireless communication signals of WIFI2.4/5 g.

At present, the SAR sensor arranged in the electronic device can generally support the detection function of 5 communication channels at most, but due to noise and temperature drift caused by the operation of the mobile phone, each detected channel needs an additional channel for compensating the noise and temperature drift, that is, only 3 channels are really available. Thus in a 5G handset, SAR sensors are typically used for control of the radiated power of the cell phone wires (e.g., including the host LTE antenna, the main set NR antennas, and the main set NR uhf antennas). And for the WIFI antenna, the control can be realized by adding an SAR sensor. The WIFI antenna can be controlled by the method and the device.

For example, when the SAR of the WIFI antenna is reduced by using the present application, a coupling component obtained by grounding the rear camera decoration is taken as an example for description, and fig. 7 is a schematic layout diagram of the WIFI antenna and the rear camera decoration in a smart phone. Wherein, D1 is the WIFI antenna, and D2 is rear camera decoration, and D3, D4, D5 and D6 are the ground part, and D7 is the ground plane in the mainboard. Four grounding members D3, D4, D5 and D6 are provided in fig. 6, wherein the grounding positions and the number of grounds of the four grounding members D3, D4, D5 and D6 are determined by simulation based on the shape and size of the rear camera garnish D2. The grounding part can be a spring sheet made of metal material. For example, assuming that in order to reduce the SAR of the WIFI antenna D1, it is determined that the grounding component D4 disposed at the upper left corner of the rear camera ornament D2 is grounded, at this time, the length of the corresponding coupling component is the side length of the side where the grounding component D4 is located in the rear camera ornament D2, so that, since the grounding component D4 is controlled to be grounded, that is, the grounding component D4 is connected to the grounding layer D7 in the motherboard, the grounding process of the rear camera ornament D2 is implemented, so that the rear camera ornament D2 generates a resonance near the radiation frequency of the WIFI antenna a, and the SAR of the WIFI antenna D1 is reduced.

Wherein the distance between two arrows in fig. 7 is less than or equal to the target distance.

Referring to fig. 8, 9, 10 and 11, there are shown corresponding detection effect diagrams after the post-camera decoration is not subjected to the grounding process and the post-camera decoration grounding process. Wherein:

fig. 8 is a frequency-standing wave ratio relationship diagram, wherein the abscissa represents frequency and the ordinate represents standing wave ratio. In the frequency-standing wave ratio diagram of fig. 8: when the distance between the rear camera decoration piece and the WIFI antenna is not within the target distance range, the curve E1 is the relation between the frequency and the standing-wave ratio obtained by detecting the WIFI antenna, and the curve E2 is the relation between the frequency and the standing-wave ratio obtained by detecting the WIFI antenna after the rear camera decoration piece is grounded. As is apparent from the frequency-standing wave ratio relationship diagram in fig. 8, in the vicinity of 2.4GHz, that is, in the circle F, the standing wave ratio of the WIFI antenna of the post-camera decoration piece after the grounding process is compared with the standing wave ratio of the WIFI antenna in which the distance between the post-camera decoration piece and the WIFI antenna is not within the target distance range, the standing wave ratio of the post-camera decoration piece after the grounding process is obviously greatly reduced, and the performance of the communication channel of the WIFI antenna at the 2.4GHz frequency band section is effectively improved.

Fig. 9 is a radiation efficiency relationship diagram of the frequency-WIFI antenna, and correspondingly, the abscissa is frequency, and the ordinate is radiation efficiency of the WIFI antenna. In the frequency-WIFI antenna radiation efficiency relationship diagram of fig. 9, G1 is the radiation efficiency of the corresponding WIFI antenna when the distance between the rear camera decoration piece and the WIFI antenna is not within the target distance range, G2 is the radiation efficiency of the WIFI antenna of the electronic device corresponding to the rear camera decoration piece after the grounding process, and it is obvious that the radiation efficiency of the WIFI antenna of G2 is greater than the radiation efficiency of the WIFI antenna of G1.

Fig. 10 is a distribution diagram of an SAR of a corresponding WIFI antenna when a rear camera trim and a WIFI antenna in an electronic device are not set within a target distance range, and fig. 11 is a distribution diagram of an SAR of a corresponding WIFI antenna when the rear camera trim is grounded in the electronic device, it is obvious that an H1 area in fig. 10 is larger than an H2 area in fig. 11, which indicates that the SAR in fig. 10 is much larger than the SAR in fig. 11, which indicates that the SAR of the WIFI antenna is effectively reduced by grounding the rear camera trim in the electronic device.

According to the control method provided by the embodiment of the application, the coupling part is grounded, so that the grounded coupling part forms resonance with the radiation frequency band of the radiation part to generate a coupling effect, the SAR in the target radiation direction of the radiation part is effectively reduced, the problem that the SAR adjusting mode of the antenna is single at present is solved, the mode of adjusting the radiation efficiency of the antenna is enriched, the scheme of effectively adjusting the radiation frequency band of the antenna is realized, the SAR peak value of the antenna is reduced, and the set SAR peak value standard is achieved. Furthermore, the electronic equipment can control the radiation frequency of part of the antennas in the electronic equipment to be reduced through the same trigger signal, so that the SAR of the part of the antennas is reduced, meanwhile, the radiation power of other antennas in the electronic equipment is also controlled to be reduced through the trigger signal, so that the SAR of other antennas is reduced, and thus, a plurality of SAR sensors are not required to be arranged in the electronic equipment to reduce the SAR of the antennas, the production cost of the electronic equipment is saved, and the difficulty in arrangement of internal components of the electronic equipment is reduced.
