Technical Field

The present disclosure relates to the field of communications technologies, and in particular, to an electronic device and an antenna control method for reducing antenna interference.

Background

At present, with the popularization of 5G antennas, the number of antennas included in electronic devices is increasing, and due to the gradual popularization of full-face screens and curved-surface screens, the space reserved for the antennas is smaller and smaller. Therefore, in the present situation, the distance between the antenna and the functional device such as the camera of the electronic apparatus will inevitably be smaller and smaller, and therefore, the antenna close to the functional device such as the camera will cause a certain interference to the functional device, for example, affect the imaging quality of the camera. Particularly, when the antenna close to the functional device such as the camera is not operated, electromagnetic wave signals of other antennas in an operating state are often coupled, and further coupled to the functional device such as the camera, so that interference is caused to the functional device such as the camera. In the prior art, in order to avoid interference to functional devices such as cameras, a mode of arranging a shielding member between an antenna and the functional devices to shield antenna signals is generally adopted, however, the cost is additionally increased, and the internal space of the electronic equipment is also more tense due to the addition of the shielding member.

In a possible implementation manner, the electronic device further comprises a radio frequency circuit, and the controller controls the target antenna to remain connected with the radio frequency circuit when determining that the antenna currently in an operating state comprises the target antenna. Therefore, when the antenna in the current working state comprises the target antenna, the target antenna is controlled to be connected with the radio frequency circuit, so that the target antenna can work normally.

The controller 600 may control the first switching tube Q1 and the second switching tube Q2 to be turned on or off by outputting corresponding level signals through the first control terminal 601 and the second control terminal 602. For example, when the first switching tube Q1 and the second switching tube Q2 are both NMOS tubes, the controller 600 may control the first switching tube Q1 to be turned on and the second switching tube Q2 to be turned off by outputting a high-level signal through the first control terminal 601 and outputting a low-level signal through the second control terminal 602, so that the target antenna 501 is connected to the radio frequency circuit 700, or control the first switching tube Q1 to be turned off and the second switching tube Q2 to be turned on by outputting a low-level signal through the first control terminal 601 and outputting a high-level signal through the second control terminal 602, so that the target antenna 501 is connected to the motherboard ground G1.

In some embodiments, the selection switch S1 may also be a single pole double throw switch, for example, the selection switch S1 further includes a throwing end fixedly connected to the static connection end P1 and selectively connected to the first dynamic connection end P2 or the second dynamic connection end P3. The controller 600 may connect the target antenna 501 to the radio frequency circuit 700 or connect the target antenna 501 to the motherboard ground G1 by controlling the throwing terminal to be connected to the first dynamic connection terminal P2 or to the second dynamic connection terminal P3.

In other embodiments, a switch (not shown) connected to the ground of the motherboard may be added to the connection line between the target antenna 501 and the rf circuit 700, and the controller 600 may control the connection between the target antenna 501 and the ground of the motherboard by controlling the switch to be turned on, and at this time, the electromagnetic wave signal will be shorted to the ground of the motherboard through the switch, so that the same grounding effect can be achieved.

Wherein, since the target antenna 501 is disposed near the functional device 400, the target antenna 501 can be used as an electromagnetic shielding member of the functional device 400 to protect the functional device 400 after being grounded.

In some embodiments, the controller 600 is configured to determine, when the electronic device 1000 is currently transmitting electromagnetic wave signals, whether the antenna 500 currently in operation includes the target antenna 501.

That is, in some embodiments, the controller 600 determines whether the antenna 500 currently in operation includes the target antenna 501, particularly when the electromagnetic wave signal is transmitted during the communication currently performed by the electronic device 1000. Since the radio frequency power of the antenna 500 is larger when the electromagnetic wave signal is transmitted, the interference to the functional device 400 is larger at this time, and the radio frequency energy of the antenna 500 is smaller when the electromagnetic wave signal is received, in some embodiments, it may be determined whether the antenna 500 currently in the working state includes the target antenna 501 only when the electromagnetic wave signal is currently transmitted, and when it is determined that the antenna 500 currently in the working state does not include the target antenna 501, the operation of grounding the target antenna 501 is controlled, so that the switching times of the target antenna 501 may be reduced, and the energy consumption may be saved.

In addition, since only one antenna 500 is in an operating state when transmitting electromagnetic wave signals, the controller 600 may determine that the antenna 500 currently in an operating state includes the target antenna 501 by determining that the antenna 500 currently in an operating state is the target antenna 501 when transmitting electromagnetic wave signals, and determine that the antenna 500 currently in an operating state does not include the target antenna 501 when determining that the antenna 500 currently in an operating state is other antennas 502, i.e., not the target antenna 501.

It is apparent that in other embodiments, the controller 600 determines whether the antenna 500 currently in operation includes the target antenna 501 whenever it is determined that the electronic device 1000 is currently in communication and that the antenna 5000 is in operation, whether transmission or reception of electromagnetic wave signals is currently performed. Therefore, even when receiving an electromagnetic wave signal, if it is determined that the antenna 500 currently in operation does not include the target antenna 501, the control unit can further reduce interference by grounding the target antenna 501.

In some embodiments, the controller 600 determines whether the antenna 500 currently in operation includes the target antenna 501 when the functional device 400 is turned on, and the functional device 400 includes at least one of a camera, a speaker, and a receiver.

That is, since it is generally necessary to consider avoiding the interference of the antenna as much as possible after the functional device 400 is turned on, in some embodiments, the controller 600 performs operations of determining whether the antenna 500 currently in operation includes the target antenna 501 when the functional device 400 is turned on, and controlling to ground the target antenna 501 when the antenna 500 currently in operation is determined to not include the target antenna 501, so as to reduce the number of times of switching the target antenna 501 and save energy consumption.

Referring to fig. 4, a schematic plan view of a schematic part of an electronic device 1000 according to an embodiment of the present application is shown. As shown in fig. 4, the functional device 400 includes a camera 401, the controller 600 determines whether the antenna 500 currently in an operating state includes a target antenna 501 when the camera 401 is turned on, and determines a current photographing scene, and the controller 600 determines whether to control the grounding of the target antenna 501 according to the current photographing scene and whether the antenna 500 currently in an operating state includes the target antenna 501.

That is, in some embodiments, when the functional device 400 includes the camera 401, the controller 600 further determines whether to control grounding the target antenna 501 in conjunction with the shooting scene that the camera 401 is turned on to shoot and whether the antenna 500 currently in a working state includes the target antenna 501, thereby avoiding frequent switching while avoiding interference to the camera 401.

In some embodiments, when the current shooting scene meets the preset condition, the controller 600 controls the target antenna 501 to remain connected to the radio frequency circuit 700 when the antenna 500 currently in the working state includes the target antenna 501 or does not include the target antenna 501; when the current shooting scene does not meet the preset condition, the controller 600 controls the target antenna 501 to remain connected with the radio frequency circuit 700 when the antenna 500 in the current working state includes the target antenna 501, and controls the target antenna 501 to be grounded when the antenna 500 in the current working state does not include the target antenna 501, wherein the preset condition is that the shooting definition requirement is lower than the preset definition.

Therefore, when the current shooting scene meets the preset condition that the shooting definition requirement is lower than the preset definition, it is indicated that the current requirement on the shooting definition is not high, so even if the antenna will interfere with the camera, the requirement on the shooting definition is not high, and therefore the interference can be ignored, at this time, when the antenna 500 in the current working state includes the target antenna 501 or does not include the target antenna 501, the target antenna 501 is controlled to be kept connected with the radio frequency circuit 700, and frequent switching of the target antenna 501 to the connection with the radio frequency circuit 700 and the main board ground G1 can be avoided. When the current shooting scene does not meet the preset condition, that is, when the shooting definition requirement of the current shooting scene is high, when the antenna 500 in the current working state includes the target antenna 501, the target antenna 501 is controlled to be connected with the radio frequency circuit 700, and when the antenna 500 in the current working state does not include the target antenna 501, the target antenna 501 is controlled to be grounded, so that interference to the camera 401 can be avoided, and imaging quality is ensured.

In some embodiments, when the controller 600 determines that the camera is triggered to be turned on by a third party software such as chat software, it determines that the current shooting scene meets a preset condition, and in general, when the chat software is chatting, in order to ensure smoothness, the definition is not too high, so the controller 600 may determine that the current shooting scene meets the preset condition, that is, determines that the shooting definition requirement is lower than the preset definition when it determines that the camera is triggered to be turned on by the third party software such as chat software. The preset definition may be a definition value of 480P, 720P, etc.

In some embodiments, the controller 600 further determines whether the current photographing scene satisfies a preset condition according to photographing definition selected by a user, for example, a selected imaging size.

In some embodiments, the controller 600 is further configured to switch on or off an antenna switching function in response to a setting operation, determine whether the antenna 500 currently in operation includes the target antenna 501 after the antenna switching function is turned on, and control to ground the target antenna 501 when it is determined that the antenna 500 currently in operation does not include the target antenna 501.

That is, in some embodiments, the operations performed by the controller 600 to determine whether the antenna 500 currently in operation includes the target antenna 501, and to control grounding of the target antenna 501 when it is determined that the antenna 500 currently in operation does not include the target antenna 501, are antenna switching control operations, and are performed after the antenna switching function is turned on.

When the controller 600 turns off the antenna switching function in response to the setting operation, the target antenna 501 is controlled to remain connected to the rf circuit 700, so that no switching is performed.

Thus, the user can control to ground the target antenna 501 when it is determined that the antenna 500 currently in the operating state does not include the target antenna 501 by setting to turn on the antenna switching function, and reduce interference to the functional device 400. Alternatively, the user may keep the target antenna 501 connected to the rf circuit 700 as in the case of the general electronic device 1000 by turning off the antenna switching function. Therefore, the control degree of the user on the control of the electronic equipment 1000 is improved, so that the user can set according to the requirements, and humanization is improved.

The setting operation may be an operation on a menu option, for example, the menu option includes an antenna switching function option, the setting operation may include a hooking operation and a cancel hooking operation on the antenna switching function option, and when the setting operation is a hooking operation on the antenna switching function option, the controller 600 may turn on the antenna switching function, that is, the controller 600 may turn on the antenna switching function in response to the hooking operation on the antenna switching function option. And when the setting operation is a cancel-and-hook operation of the antenna switching function option, the controller 600 may turn off the antenna switching function, i.e., the controller 600 may turn off the antenna switching function in response to the cancel-and-hook operation of the antenna switching function option.

It is apparent that, in some embodiments, after the antenna switching function is turned on, the controller 600 may further determine whether the transmission of the electromagnetic wave signal is currently performed and/or whether the functional device 400 is turned on, and perform the operations of determining whether the antenna 500 currently in operation includes the target antenna 501 when the transmission of the electromagnetic wave signal is currently performed and/or the functional device 400 is turned on, and controlling the grounding of the target antenna 501 when the antenna 500 currently in operation is determined not to include the target antenna 501, and so on.

That is, the various cases of the antenna switching function being turned on, the electromagnetic wave signal being transmitted currently, and the functional device 400 being turned on, etc. described in the present application may be arbitrarily combined, and then in various cases of arbitrary combination, the operations of determining whether the antenna 500 currently in the operation state includes the target antenna 501, and controlling the grounding of the target antenna 501 when it is determined that the antenna 500 currently in the operation state does not include the target antenna 501, etc. are performed.

In some embodiments, the controller 600 may further be configured to generate a prompt when it is determined that the antenna currently in operation does not include the target antenna, where the prompt is used to prompt a user whether to determine to ground the target antenna 501, and the controller 600 controls to ground the target antenna 501 when receiving a reply of determining to ground the target antenna 501.

That is, in some embodiments, the controller 600 does not directly control the grounding of the target antenna 501 when determining that the antenna currently in the working state does not include the target antenna, but generates a prompt message to prompt the user whether to determine to ground the target antenna 501, and controls the grounding of the target antenna 501 only when receiving a reply of determining to ground the target antenna 501 input by the user, thereby further improving the control of the user on the electronic device 1000 and improving humanization.

The display module 200 may include a display screen, and the controller 600 may display the prompt information through the display screen. In other embodiments, the prompt information may be voice information, and the controller 600 may output the prompt information through a speaker, and control the grounding of the target antenna 501 when receiving a reply in the form of voice input by the user, which determines to ground the target antenna 501.

Fig. 5 is a schematic diagram of a prompt message in an embodiment of the present application. As shown in fig. 5, the prompt information may include prompt content, for example: if it is determined to ground the target antenna, the prompt may further include a "yes" and "no" confirmation box, and the user may click "yes" to generate a reply to determine to ground the target antenna 501, and may click "no" to generate a reply to not ground the target antenna 501, and the controller 600 receives the corresponding reply generated in response to the user operation, and controls to ground the target antenna 501 or keep the target antenna 501 connected to the rf circuit 700. Wherein the display screen may be a touch display screen.

Wherein in some embodiments, the target antenna 501 is disposed near the power supply device 400, which may also mean that the distance between the target antenna 501 and the functional device 400 is smaller than a preset distance, for example, 5 mm, and/or that the projection of the target antenna 501 and the functional device 400 on the display screen of the display module 200 of the electronic device 1000 at least partially coincides.

Referring back to fig. 4, as shown in fig. 4, the plurality of antennas 500 includes a target antenna 501 disposed close to the camera 401 and other antennas 502 disposed far from the camera 401.

As shown in fig. 4, the target antenna 501 may be a planar antenna, and is spaced from and close to the camera 401 in a direction perpendicular to the display screen of the electronic device 1000, and as shown in fig. 4, the projection of the camera 401 on the display screen of the electronic device 1000 is located in the projection area of the target antenna 501 on the display screen of the electronic device 1000. Thus, in this case, the target antenna 501 will interfere with the camera 401. According to the scheme, when the target antenna is not in the working state, the target antenna is controlled to be grounded, and interference to the functional device 400 can be avoided at least in part of time, so that the interference can be effectively reduced as a whole.

In addition, since the target antenna 501 is disposed near the functional device 400, the target antenna 501 can be used as an electromagnetic shield of the functional device 400 to protect the functional device 400 after being grounded. When the projection of the camera 401 on the display screen of the electronic device 1000 is located in the projection area of the target antenna 501 on the display screen of the electronic device 1000, the target antenna 501 can more fully protect the camera 401, so as to achieve the effect similar to a faraday cage.

As shown in fig. 4, the target antenna 501 is selectively connected to the radio frequency circuit 700 or to the main board ground G1 through a selection switch S1. The selection switch S1 illustrated in fig. 4 is a single pole double throw switch.

In some embodiments, the camera 401 is a rear camera. Obviously, in other embodiments, the camera 401 may be a front camera.

In some embodiments, the target antenna 501 may be disposed on the circuit board 300, for example, the antenna target 501 may be disposed on an antenna mount that is secured to the circuit board 300 and then disposed on the circuit board 300 via the antenna mount. The target antenna 501 may be an FPC (flexible printed circuit) antenna fixedly disposed on the antenna support or an LDS (Laser-Direct-structuring) antenna formed on the antenna support by a Laser technology. The FPC antenna refers to a metal antenna pattern formed on the FPC, and the FPC antenna can be fixed on the antenna bracket in a bonding, embedding, welding and other modes. The LDS antenna refers to a metal antenna pattern which is directly plated on an antenna bracket made of the insulating material through a laser technology.

The other antenna 502 may be disposed on the circuit board 300, or may be an antenna formed by sharing a metal frame of the electronic device 1000.

As shown in fig. 4, the other antennas 502 may include a first antenna 5021, a second antenna 5022 and a third antenna 5023, where the first antenna 5021, the second antenna 5022 and the third antenna 5023 are all disposed near the frame of the electronic device 1000, and the first antenna 5021 may be disposed at a vertex angle of the electronic device 1000, and specifically, the first antenna 5021 includes a portion parallel to a short side B1 of the electronic device 1000 and a portion parallel to a long side B2 of the electronic device 1000 adjacent to the short side B1, so as to form an L-shaped antenna. The second antenna 5022 may be disposed at another vertex angle position of the electronic device 1000, where the other vertex angle position where the second antenna 5022 is disposed and the vertex angle position where the first antenna 5021 is disposed share a short side, specifically, the second antenna 5022 includes a portion parallel to the short side B1 of the electronic device 1000 and a portion parallel to another long side B2 of the electronic device 1000 adjacent to the short side B1, so as to form an L-shaped antenna. The third antenna 5023 is a strip antenna, the third antenna 5023 is disposed at intervals with the first antenna 5022, and the third antenna 5023 is coincident with or parallel to an extension line of a portion of the first antenna 5021 parallel to the long side B2. Therefore, through the structure, better 5G radio frequency performance can be realized.

In some embodiments, the functional device 400 may be one, such as just the camera 401, the target antenna 501 may be an N1 antenna, and the other antennas may include a WIFI antenna, a GSM 2G antenna, a 5G N1 antenna, and so on. In some embodiments, the first antenna 5021 is a 5G N1 antenna, the second antenna 5022 is a GSM 2G antenna, and the third antenna 5023 is a WIFI antenna.

In other embodiments, the functional device 400 may be plural, for example, may include at least two of a camera 401, a receiver, and a speaker, and the target antenna 501 may also include at least two. Accordingly, the aforementioned selection switch S1 and the like may also include at least two, so that, when the controller 600 determines that the antenna 500 currently in operation includes the target antenna 501, the controller may perform the aforementioned functions, for example, control each of the target antennas 501 in operation to be grounded through the corresponding selection switch S1 connected thereto. The specific structure and manner in which each target antenna 501 is grounded through the corresponding selection switch S1 connected thereto are described in detail in the foregoing.

In some embodiments, the controller 600 is further configured to determine the antenna 500 currently in operation when the electronic device 1000 is in communication. Wherein the controller 600 may determine whether the antenna 500 currently in operation includes the target antenna 501 by determining a frequency band used in the current communication. Since the operating frequency bands corresponding to the plurality of antennas 500 provided in the electronic device 1000 are fixed and have certain differences, the controller 600 may determine which of the corresponding antennas 500 in an operating state is by determining the frequency band used in the current communication, and then may determine whether to include the target antenna 501. The communication in the application can include communication in the case of making a call, video chat, voice chat, short message interaction and the like.

In some embodiments, the controller 600 is further configured to control, when the current communication is finished, to switch the target antenna 501 to be connected to the corresponding radio frequency circuit 700 or to keep being connected to the corresponding radio frequency circuit 700, so that the default state of the target antenna 501 is that the target antenna is kept connected to the corresponding radio frequency circuit 700, and the target antenna 501 is not controlled to be grounded until the next time it is determined that the target antenna 501 needs to be grounded.

The radio frequency circuit 700 in the present application may include a radio frequency transceiver circuit, a matching circuit, a feed source, and the like, and is configured to cooperate with the antenna 500 to realize the transceiver of electromagnetic wave signals. Wherein the radio frequency circuit 700 may include one or more of the plurality of antennas 500 connected to different radio frequency circuits 700, or at least two antennas 500 share one radio frequency circuit 700. The other antennas 502 in the plurality of antennas 500 are directly connected to the corresponding rf circuits 700, that is, the selection switch S1 is not disposed between the other antennas 502 and the corresponding rf circuits 700, but the connection between the other antennas 502 and the corresponding rf circuits 700 is always maintained.

Fig. 6 is a flowchart of an antenna control method according to an embodiment of the present application. The antenna control method is applied to an electronic device, wherein the electronic device comprises a plurality of antennas, and the method can comprise the following steps:

S601: determining whether an antenna in a current working state comprises a target antenna, wherein the target antenna is an antenna which is arranged close to a functional device of the electronic equipment. If not, step S603 is performed.

S603: and when the antenna in the current working state is determined not to comprise the target antenna, controlling the target antenna to be grounded.

Therefore, when the antenna in the current working state does not comprise the target antenna, the control is carried out to ground the target antenna, so that electromagnetic wave signals coupled to the target antenna by other antennas can be conducted to the ground without being coupled to the functional device, and the interference to the functional device can be effectively reduced.

Wherein the electronic device further comprises a radio frequency circuit, as shown in fig. 6, the method further comprises:

s605: and when the antenna in the current working state is determined to comprise the target antenna, controlling the target antenna to be kept connected with the radio frequency circuit. That is, if the determination result of step S601 is yes, step S605 is executed.

The target antenna is connected with the radio frequency circuit by default, and when the antenna in the current working state comprises the target antenna, the target antenna is controlled to be kept connected with the radio frequency circuit, so that the target antenna can work normally.

In some embodiments, the electronic device further comprises a selection switch connected between the target antenna, the radio frequency circuit, and a motherboard ground, and selectively connecting the target antenna to the radio frequency circuit or the motherboard ground; the controlling grounds the target antenna, including: and controlling the selection switch to connect the target antenna to the main board ground, so as to control the target antenna to be grounded.

In some embodiments, the step S601 may specifically include: and when the electronic equipment currently transmits electromagnetic wave signals, determining whether the antenna currently in a working state comprises a target antenna or not.

That is, in some embodiments, it is determined whether the antenna currently in operation includes the target antenna, particularly when the communication currently in progress is electromagnetic wave signal transmission. Because the radio frequency power of the antenna is larger when the electromagnetic wave signal is transmitted, the interference to the functional device is larger at the moment, and the radio frequency energy of the antenna is smaller when the electromagnetic wave signal is received, in some embodiments, whether the antenna in the current working state comprises the target antenna or not can be determined only when the electromagnetic wave signal is transmitted currently, and when the antenna in the current working state does not comprise the target antenna is determined, the target antenna is controlled to be grounded, and the like, so that the switching times of the target antenna can be reduced, and the energy consumption can be saved.

In some embodiments, the step S601 may specifically include: and when the functional device is started, determining whether the antenna in the current working state comprises a target antenna, wherein the functional device comprises at least one of a camera, a loudspeaker and a receiver.

Since it is generally necessary to consider avoiding the interference of the antenna as much as possible after the functional device is turned on, in some embodiments, determining whether the antenna currently in operation includes the target antenna may be performed only when the functional device is turned on, and when determining that the antenna currently in operation does not include the target antenna, controlling to ground the target antenna may be performed, so as to reduce the number of times of switching the target antenna and save energy.

In some embodiments, the functional device includes a camera, and when the functional device is turned on, determining whether the antenna currently in an operating state includes a target antenna includes: when the camera is started, determining whether the antenna in the current working state comprises a target antenna or not, and determining the current shooting scene. The method further comprises the steps of: and determining whether to control the grounding of the target antenna according to the current shooting scene and whether the antenna in the current working state comprises the target antenna.

Therefore, in some embodiments, when the functional device includes a camera, the camera is turned on, and further needs to be combined with a shooting scene that the camera is turned on to shoot and whether the antenna currently in a working state includes a target antenna, so as to determine whether to control the target antenna to be grounded, thereby avoiding frequent switching while avoiding causing interference to the camera.

The determining whether to control the grounding of the target antenna according to the current shooting scene and whether the antenna in the current working state comprises the target antenna may specifically include: when the current shooting scene meets preset conditions, controlling the target antenna to be connected with the radio frequency circuit when the antenna in the current working state comprises the target antenna or does not comprise the target antenna; when the current shooting scene does not meet the preset condition, when the antenna in the current working state comprises a target antenna, controlling the target antenna to be connected with the radio frequency circuit, and when the antenna in the current working state does not comprise the target antenna, controlling the target antenna to be grounded, wherein the preset condition is that the shooting definition requirement is lower than the preset definition.

In some embodiments, the method further comprises: in response to a set operation to turn the antenna switching function on or off. The determining whether the antenna currently in the working state comprises a target antenna comprises: after the antenna switching function is turned on, it is determined whether the antenna currently in an operating state includes a target antenna.

Thus, the user can control the target antenna 501 to be grounded when determining that the antenna currently in the working state does not include the target antenna by setting to turn on the antenna switching function, so as to reduce interference to the functional device. Alternatively, the user may keep the target antenna connected to the radio frequency circuit all the time, as in a normal electronic device, by turning off the antenna switching function. Therefore, the control degree of the user on the control of the electronic equipment is improved, so that the user can set according to the requirements, and humanization is improved.

In some embodiments, when determining that the antenna currently in the working state does not include the target antenna, controlling to ground the target antenna includes: when the antenna in the current working state is determined not to comprise the target antenna, generating a prompt message, wherein the prompt message is used for prompting a user whether to determine to ground the target antenna; and controlling to ground the target antenna when receiving a reply of determining to ground the target antenna.

In some embodiments, when it is determined that the antenna currently in operation does not include the target antenna, instead of directly controlling the grounding of the target antenna, a prompt message is generated to prompt the user whether to determine to ground the target antenna, and when a reply is received from the user that the determination is made to ground the target antenna 501, the grounding of the target antenna is controlled, which further improves humanization.

The antenna control method may be applied to the electronic device 1000, and more specific details may be found in the foregoing description of the electronic device 1000.

Referring to fig. 7, a flowchart of an antenna control method according to another embodiment of the present application is shown in fig. 7, where the method includes the steps of:

s701: in response to a set operation to turn on the antenna switching function.

S703: determining whether an antenna in a current working state comprises a target antenna, wherein the target antenna is an antenna which is arranged close to a functional device of the electronic equipment.

S705: and when the antenna in the current working state is determined not to comprise the target antenna, controlling the target antenna to be grounded.

S707: and when the antenna in the current working state is determined to comprise the target antenna, controlling the target antenna to be kept connected with the radio frequency circuit.

That is, in some embodiments, the operation of determining whether the antenna currently in operation includes the target antenna or not may be performed after the antenna switching function is turned on in response to the setting operation.

The steps S703, S705 and S707 correspond to the steps S601, S603 and S605 in fig. 6, respectively, and more specific details can be found in the foregoing description related to fig. 6.
