Detailed Description

According to the scheme, the antenna radiation of the electronic equipment can be reasonably controlled, so that the communication quality of the electronic equipment accessed to a communication network through other electronic equipment or the communication quality of the electronic equipment accessed to the communication network through the electronic equipment is improved.

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without undue burden, are within the scope of the present application.

Fig. 1 is a schematic flow chart of an antenna control method according to an embodiment of the present application, where the method of the present embodiment is applied to a first electronic device.

The first electronic device may be a hub device connected between different networks, for example, the first electronic device may be a router or other gateway device, which may be capable of accessing other electronic devices into a communication network.

The first electronic device may also be a terminal device such as a notebook computer, a mobile phone, and an intelligent home appliance, where in this case, the first electronic device may access a communication network through a network access point provided by a router or other electronic devices.

The method of the embodiment can comprise the following steps:

s101, at least one second electronic device which establishes wireless network connection with the first electronic device is determined.

The wireless network connection established between the first electronic device and the second electronic device can be divided into the following two cases:

one case is: the first electronic device may be accessing the communication network through the second electronic device.

For example, the first electronic device is a mobile phone (or a notebook computer, etc.), and the second electronic device is a router or other gateway device, then the mobile phone accesses the communication network through a WiFi network or a local area network provided by the access router or the gateway device.

In this case, the number of second electronic devices may be one considering that the electronic devices can only access one router or gateway device at the same time.

In another case, the second electronic device accesses the communication network through the first electronic device, and then a wireless network connection is also established between the first electronic device and the second electronic device. For example, the first electronic device is a router or other gateway device, and the first electronic device can be connected to a plurality of second electronic devices (such as a mobile phone, a smart home appliance or a notebook computer) at the same time, so that the plurality of second electronic devices can access the communication network through the first electronic device at the same time.

S102, determining relative azimuth information of the second electronic device relative to the first electronic device.

The relative azimuth information of the second electronic device relative to the first electronic device may include: at least one of information of relative direction, relative distance and relative height of the second electronic device relative to the first electronic device.

There are a variety of ways to determine the relative orientation information between the first electronic device and the second electronic device.

For example, in one possible implementation, the first electronic device and the second electronic device are both configured with Ultra Wideband (UWB) modules, and the first electronic device may determine the relative orientation information of the second electronic device with respect to the first electronic device through UWB technology. For example, a UWB wireless carrier communication connection between the first electronic device and the second electronic device may be established, and relative position information of the second electronic device with respect to the first electronic device may be determined based on the UWB wireless carrier communication connection.

Of course, the first electronic device may also determine one or more of the relative distance, the relative direction, and other relative azimuth information of the second electronic device with the aid of radar and other positioning technologies, which is not limited by the specific implementation of determining the relative azimuth information.

S103, controlling radiation of an antenna in the first electronic device based on the relative azimuth information of each of the at least one second electronic device.

Controlling the radiation of the antenna in the first electronic device in the present application may comprise: one or more of the information of the radiation direction, the radiation pattern, the radiation intensity of the antenna and the like of the antenna in the first electronic device is controlled, which is not limited.

It can be understood that the relative azimuth information of the second electronic device relative to the first electronic device reflects information such as a direction and a distance suitable for transmitting the communication signal between the first electronic device and the second electronic device, so that the radiation of the antenna in the first electronic device can be more reasonably controlled by combining the relative azimuth information.

It will be appreciated that after the first electronic device establishes a wireless network connection with the second electronic device, the relative orientation information between the first electronic device and the second electronic device may change as the location of the first electronic device or the second electronic device changes. Based on this, steps S102 and S103 may be performed multiple times in the present application, so that after the relative azimuth information between the first electronic device and the second electronic device is changed, the radiation of the antenna in the first electronic device can still be reasonably controlled based on the adjusted relative azimuth information.

Therefore, in the embodiment of the application, when the electronic device and other electronic devices are connected to the communication network or other electronic devices are connected to the communication network through the electronic device, the electronic device determines the relative azimuth information of each other electronic device connected to the electronic device, so that the antenna radiation of the electronic device can be reasonably controlled according to the relative azimuth information of each other electronic device, further, the communication quality between the electronic device and other electronic devices can be improved, and the poor signal receiving and transmitting conditions are reduced.

To facilitate an understanding of the possible ways of controlling the radiation of the antenna, several possible cases of controlling the radiation of the antenna are described below.

First, a case where the radiation direction of the antenna is controlled will be described as an example.

As shown in fig. 2, which shows a schematic flow chart of an antenna control method provided in an embodiment of the present application, the method of the present embodiment is applied to a first electronic device, and the embodiment may include:

s201, at least one second electronic device establishing wireless network connection with the first electronic device is determined.

The first electronic device is accessed to the communication network through the second electronic device, or the second electronic device is accessed to the communication network through the first electronic device.

S202, for each second electronic device, determining the relative orientation information of the second electronic device relative to the first electronic device.

The relative orientation information includes at least relative orientation information of the second electronic device with respect to the first electronic device. The relative orientation information may also include relative distance information of the second electronic device with respect to the first electronic device.

The above two steps can be referred to the related description of the previous embodiments, and will not be repeated here.

And S203, controlling the directional radiation direction of the antenna in the first electronic device based on the respective relative direction information of the at least one second electronic device so that the directional radiation area of the antenna covers the at least one second electronic device.

For example, controlling the directional radiation direction of the antenna may include: the radiation direction of the directional radiation of the antenna is determined based on the respective relative direction information of the at least one second electronic device, and the directional radiation of the antenna is controlled. The directional radiation area of the antenna can cover at least one second electronic device by radiating the signal outwards according to the determined directional radiation direction.

For example, taking the case that the first electronic device is connected to a second electronic device through a wireless network, the relative direction of the second electronic device with respect to the first electronic device may be determined as the directional radiation direction of the antenna of the first electronic device, so as to control the radiation signal of the antenna in the direction of the second electronic device to be strongest.

If the first electronic device is connected with a plurality of second electronic devices through a wireless network, the direction of the directional radiation can be comprehensively determined by combining the relative direction information of the plurality of second electronic devices, so that at least one second electronic device can better receive the signals radiated by the antenna of the first electronic device.

It can be appreciated that in practical applications, in the case where the antenna of the first electronic device radiates in a directional radiation mode, the radiation angle range that can be radiated by the antenna may be preset. On this basis, in the case that the second electronic devices have a plurality of second electronic devices and the difference between the relative azimuth information of the second electronic devices is large, if the radiation angle range of the directional radiation of the antenna in the first electronic device is fixed, the antenna may be caused to cover all the second electronic devices more comprehensively in the process of the directional radiation. Based on this, the controlling the directional radiation direction of the antenna in the first electronic device may further include combining the relative azimuth information of each second electronic device, and adjusting the radiation angle range of the directional radiation of the antenna, for example, increasing the radiation angle range, so that the antenna can radiate to the plurality of second electronic devices as comprehensively as possible and enhance the intensity of communication signals between each second electronic device and the first electronic device as possible on the premise that the antenna radiates signals in a directional radiation manner.

Therefore, in this embodiment, the directional radiation direction of the antenna in the first electronic device can be more reasonably controlled by combining the relative direction information of each second electronic device connected with the first electronic device, so that the radiation intensity of the antenna in the direction of the second electronic device is enhanced, and the communication quality between the first electronic device and the second electronic device can be naturally improved.

It will be appreciated that in the case where the radiation intensity of the directional radiation of the antenna in the first electronic device is the same, the relative distance of the second electronic device from the first electronic device will be different, and the quality of communication will be different between the first electronic device and the second electronic device.

Based on this, in order to further improve the communication quality between the first electronic device and the second electronic device, the relative azimuth information of the second electronic device determined in this embodiment may further include relative distance information of the second electronic device relative to the first electronic device. Accordingly, the controlling radiation of the antenna in the first electronic device according to the present application may further include: the radiation intensity of the antenna in the direction of the directional radiation is controlled based on the respective relative distance information of the at least one second electronic device.

For example, based on the relative distance information of each second electronic device with respect to the first electronic device, the furthest relative distance of each second electronic device with respect to the first electronic device is determined, and the radiation intensity of the antenna in the directional radiation direction is increased or decreased based on the furthest relative distance.

It can be understood that by reasonably adjusting the radiation intensity of the antenna of the first electronic device in the directional radiation direction, the communication quality between the first electronic device and the second electronic device can be effectively ensured; the radiation intensity of the antenna can be reasonably controlled, so that unnecessary resource consumption is reduced, and the power consumption of the electronic equipment is reduced.

It is understood that the antenna of the first electronic device may support one or more frequency bins. For example, the antenna of the first electronic device may support not only the 2.4GHz band but also the 5GHz band. On the basis, the method and the device can also determine the respective working frequency range of each second electronic device.

The manner in which the first electronic device determines the operating frequency band of the second electronic device may have a plurality of possible manners. For example, when or after the first electronic device establishes a wireless network connection with the second electronic device, the first electronic device may obtain a communication parameter reported by the second electronic device, or the first electronic device actively requests the communication parameter of the second electronic device to the second electronic device. The communication parameters include at least an operating frequency band of the second electronic device.

Based on the above, the application can determine at least one target frequency band range needing to enhance the radiation intensity based on the respective working frequency band of the at least one second electronic device and at least one frequency band interval supported by the antenna. Accordingly, in order to improve the communication quality between the first electronic device and the second electronic device, the radiation intensity in each target frequency band range may be enhanced in the directional radiation direction of the antenna of the first electronic device.

It can be appreciated that when a change in the relative azimuth information of the second electronic device is detected, the present application may also adjust the directional radiation direction of the antenna in the first electronic device based on the current respective relative azimuth information of at least one second electronic device.

If there is a change in the relative azimuth information of the second electronic devices, the directional radiation direction of the antenna is adjusted based on the relative direction information of each second electronic device. Of course, the current relative distance information of each second electronic device can be combined, so that the radiation intensity of the antenna in the current directional radiation direction can be adjusted.

It will be appreciated that the above is described by taking the first electronic device as an example with one antenna. In practical applications, the first electronic device may also have multiple antennas.

Under the condition that the first electronic equipment is provided with a plurality of antennas, the plurality of antennas can be regarded as a whole, and based on the relative direction information of the second electronic equipment, the method can determine the directional radiation directions of the plurality of antennas and control the plurality of antennas to perform directional radiation according to the determined directional radiation directions. Wherein the radiation directions of the directional radiation of the plurality of antennas are the same.

Further, the radiation intensity of the plurality of antennas in the radiation direction of the directional radiation can be determined based on the relative distance information of the second electronic devices, for example, the radiation intensity of the whole plurality of antennas is determined; alternatively, the radiation intensity of the plurality of antennas is determined in the directional radiation direction, and the radiation intensity of the single antenna is determined. On the basis, the plurality of antennas can be controlled to radiate in the directional radiation direction according to the determined radiation intensity, so that the signal radiation intensity in the radiation direction can better meet the communication requirement of communication between the first electronic equipment and each second electronic equipment.

Of course, in the case that at least one target frequency band range needing to enhance radiation is determined based on the working frequency band of the second electronic device, the application can determine at least one target antenna supporting the target frequency band range in the multiple antennas, and control each target antenna to enhance the radiation intensity of the target frequency band range in the directional radiation direction.

The following description will take the radiation mode of the control antenna as an example.

Fig. 3 is a schematic flowchart of another antenna control method according to an embodiment of the present application, where the method of the present embodiment is applied to a first electronic device.

The method of the embodiment can comprise the following steps:

s301, at least one second electronic device establishing wireless network connection with the first electronic device is determined.

The first electronic device is accessed to the communication network through the second electronic device, or the second electronic device is accessed to the communication network through the first electronic device.

S302, for each second electronic device, determining the relative orientation information of the second electronic device relative to the first electronic device.

The above two steps can be referred to the related description of the previous embodiments, and will not be repeated here.

S303, determining a target radiation mode suitable for the antenna of the first electronic device based on the relative azimuth information of the at least one second electronic device.

In this embodiment, the antenna of the first electronic device supports two radiation modes, one is a directional radiation mode and the other is an omni-directional radiation mode, and the first electronic device can switch between the two radiation modes according to actual needs.

Accordingly, the target radiation pattern belongs to one of a directional radiation pattern and an omnidirectional radiation pattern.

The omni-directional radiation mode is also referred to as an omni-directional type field or a broadcast type field, and refers to that the antenna of the first electronic device uniformly radiates in different directions, so that the intensity of communication signals received and transmitted in different directions is the same or similar. Correspondingly, under the condition that the antenna of the first electronic device radiates in an omnidirectional radiation mode, the signal intensities of the first electronic device detected by other electronic devices positioned in different directions of the first electronic device are the same or similar.

The directional radiation mode is also called a directional transceiver mode or a directional field type, and means that the radiation intensity of the first electronic device in a certain direction is strong, and the radiation intensity of the antenna in other direction areas except the direction is weak. On the basis, the intensity of the communication signal sent out by the first electronic device sensed by other electronic devices positioned in the directional radiation direction of the antenna of the first electronic device is higher, and the intensity of the communication signal sent out by the first electronic device sensed by other electronic devices positioned outside the directional radiation direction is weaker.

For example, when the first electronic device uses the directional radiation mode to radiate the antenna, in a direction region other than the directional radiation direction of the antenna, the radiation intensity of the antenna may be controlled to maintain that the first electronic device can detect other electronic devices, and the other electronic devices can sense or detect the first electronic device.

It will be appreciated from the description of the directional radiation pattern and the omnidirectional radiation pattern that the appropriate scenarios for the directional radiation pattern and the omnidirectional radiation pattern may also vary. Correspondingly, the relative azimuth information of each second electronic device relative to the first electronic device is different, and the proper radiation modes are also different, so that the antenna radiation mode which can ensure the communication between each second electronic device and the first electronic device and can furthest improve the communication quality can be reasonably selected and determined by combining the relative azimuth information of each second electronic device.

If the relative position information of each second electronic device relative to the first electronic device indicates that the position distribution range of at least one second electronic device exceeds a set range threshold, determining that the antenna is suitable for an omnidirectional radiation mode; otherwise, it is determined that the antenna is suitable for the directional radiation pattern.

For another example, in consideration of the situation that the first electronic device is connected to more second electronic devices and the second electronic devices are far away from the first electronic device, the second electronic device may continuously change the adjustment position to improve the communication quality with the first electronic device, which results in a larger change of the relative azimuth information of the second electronic device. Based on the above, in order to avoid that the communication quality between the second electronic device and the first electronic device frequently changes greatly, determining an omnidirectional radiation mode suitable for the antenna when the minimum value or the average value in the relative distance between each second electronic device and the first electronic device exceeds a set threshold value; otherwise, it is determined that the antenna is suitable for a directional radiation pattern.

As another example, in one possible implementation, it may be determined whether the at least one second electronic device is capable of being simultaneously within the directional radiation range of the antenna of the first electronic device based on the respective relative direction information of the at least one second electronic device and the maximum radiation angle range of the antenna of the first electronic device under directional radiation.

Accordingly, if the at least one second electronic device is capable of being simultaneously within the directional radiation range of the antenna, determining that the antenna is suitable for a radiation pattern that is a directional radiation pattern. Otherwise, if the at least one second electronic device is not capable of being simultaneously within the directional radiation range of the antenna, determining that the antenna is suitable for a radiation mode that is an omnidirectional radiation mode.

The maximum radiation angle range of the antenna under the directional radiation refers to the angle range of the antenna which can radiate maximally under the condition of directional radiation.

It will be appreciated that if it is determined, based on the respective relative azimuth information of at least one second electronic device, that at least one second electronic device cannot be all located within the directional radiation range of the antenna of the first electronic device, it is stated that in the case where the antenna of the first electronic device adopts the directional radiation mode, the directional radiation area cannot be made to completely cover each second electronic device, so that the communication quality of communication between the first electronic device and some second electronic devices may be affected, and therefore, in this case, the antenna of the first electronic device is not suitable for adopting the directional radiation mode.

S304, controlling the radiation of the antenna according to the target radiation mode.

For example, if the target radiation pattern is an omni-directional radiation pattern, the first electronic device may control its antenna to radiate uniformly in all directions, so as to ensure that the second electronic device in different directions can reliably perform data transmission with the first electronic device.

If the target radiation pattern is a directional radiation pattern, the antenna may be controlled to radiate directionally in the direction in which the at least one second electronic device is located.

Particularly, in the case that the target radiation mode is a directional radiation mode, the present application may also control the directional radiation direction of the antenna of the first electronic device and the radiation intensity in the directional radiation direction by combining the relative azimuth information of each second electronic device relative to the first electronic device, which may be specifically described with reference to the embodiment of fig. 2, and will not be described herein.

In this example, the relative azimuth information of each second electronic device connected with the first electronic device is combined to determine whether the antenna of the first electronic device is suitable for the directional radiation mode, so that the situation that the directional radiation mode is opened by reasonably controlling the electronic device under the condition that the first electronic device and each second electronic device normally communicate can be fully considered, and the situation that communication between the first electronic device and the second electronic device is influenced because the directional radiation area cannot fully cover all the second electronic devices is reduced.

It will be appreciated that, similar to the previous embodiment, in the case where a change in the relative azimuth information of the second electronic device is detected, the present application may also determine, based on the current respective relative azimuth information of at least one second electronic device, a target radiation pattern suitable for the antenna of the first electronic device, so as to reasonably adjust the radiation pattern adopted by the antenna of the first electronic device in the case where a change in the relative azimuth of the second electronic device occurs.

In the embodiment of fig. 3, one antenna of the first electronic device is also taken as an example, and in practical application, the first electronic device may have multiple antennas. In the case that the first electronic device has multiple antennas, the multiple antennas can be regarded as a whole, and based on the combination of the relative azimuth information of the second electronic devices, the target radiation mode suitable for the multiple antennas can be determined. The process of determining the target radiation pattern suitable for the multiple antennas is similar to the process of determining the target radiation pattern suitable for the single antenna, and will not be described herein.

It is understood that controlling the radiation of the antenna in this application may also include controlling both the radiation pattern of the antenna and the radiation direction of the directional radiation, etc. For ease of understanding, the following description may be made in connection with one implementation.

As shown in fig. 4, which is a schematic flow chart of an antenna control method provided in an embodiment of the present application, the method of the present embodiment may include:

s401, at least one second electronic device establishing wireless network connection with the first electronic device is determined.

The first electronic device is accessed to the communication network through the second electronic device, or the second electronic device is accessed to the communication network through the first electronic device.

S402, for each second electronic device, determining relative orientation information of the second electronic device relative to the first electronic device.

The relative orientation information may include relative orientation information and relative distance information of the second electronic device relative to the first electronic device.

S403, determining whether at least one second electronic device can be simultaneously in the directional radiation range of the antenna based on the respective relative direction information of the at least one second electronic device and the maximum radiation angle range of the antenna of the first electronic device under the directional radiation, and if so, executing step S404; if not, step S407 is performed.

S404, determining the directional radiation direction of the antenna in the first electronic device based on the respective relative direction information of the at least one second electronic device.

It will be appreciated that if the at least one second electronic device is able to be simultaneously within the directional radiation range of the antenna of the first electronic device, the first electronic device may determine that the antenna is suitable for the directional radiation pattern. Compared with the omni-directional radiation mode, the signal radiation intensity in the directional radiation direction can be enhanced through the directional radiation mode, so that the communication quality between each second electronic device and each first electronic device in the directional radiation range can be improved.

Under the condition that the antenna is suitable for the directional radiation mode, in order to ensure that the directional radiation area can cover each second electronic device, the method and the device can more reasonably determine the directional radiation direction by combining the relative direction information of each second electronic device, so that the directional radiation area of the antenna of the first electronic device can cover each second electronic device more comprehensively and reliably, and the signal transmission quality between the first electronic device and the second electronic device is improved.

S405, determining the radiation intensity of the antenna of the first electronic device in the directional radiation direction based on the respective relative distance information of the at least one second electronic device.

For example, the distance between each second electronic device and the first electronic device is relatively short, for example, the relative distance between each second electronic device and the first electronic device is smaller than a set distance threshold, so that the radiation intensity can be properly reduced on the basis of the set reference radiation intensity, and the power consumption of the first electronic device can be reduced on the premise of not affecting the communication quality. On the contrary, if the second electronic equipment far away from the first electronic equipment exists, the radiation intensity can be properly increased on the basis of the reference radiation intensity, so that the communication quality between the second electronic equipment far away and the first electronic equipment can be more reliably ensured.

It will be appreciated that determining the directional radiation direction and the appropriate radiation intensity in the directional radiation direction may be referred to in the description of the previous embodiments and will not be repeated here.

And S406, controlling the antenna to conduct directional radiation according to the determined directional radiation direction and radiation intensity, so that the directional radiation area of the antenna covers the at least one second electronic device.

It may be appreciated that, before the step S406, the first electronic device may further determine, based on the operating frequency band of each second electronic device, at least one target frequency band range in which the radiation intensity needs to be enhanced from at least one frequency band interval supported by the antenna. On the basis, the method and the device can enhance the radiation intensity in each target frequency band range in the directional radiation direction of the antenna when the directional radiation of the antenna is controlled.

Of course, it is also possible to determine the radiation intensity of the antenna corresponding to each target frequency band range in the directional radiation direction in step S406, and control the antenna to radiate in the directional radiation direction based on the radiation intensity of the antenna in each target frequency band range.

S407, determining that the proper radiation mode of the antenna is an omnidirectional radiation mode, and controlling the antenna to radiate by adopting the omnidirectional radiation mode.

To facilitate understanding of the aspects of the present embodiments, a description is provided in connection with an application scenario. The description is made with reference to an architecture diagram of an application scenario shown in fig. 5:

the first electronic device is taken as a router, and the second electronic device can be a terminal device such as a mobile phone or a notebook computer, which needs to be accessed to a communication network by the router.

As shown in fig. 5, an Ultra Wideband (UWB) module is configured in a router 501 as a first electronic device, and a UWB module is also configured in a notebook computer 502 as a second electronic device. It will be appreciated that there may be multiple second electronic devices accessing the router, and that for each second electronic device, the information interaction process between the routers is similar, so that only one notebook computer is shown in fig. 5 as the second electronic device.

After the notebook computer 502 is connected to the router, the router 501 and the notebook computer can be positioned based on UWB technology, so that the UWB module of the router 501 can determine the relative azimuth information of the notebook computer 502 relative to the router. Accordingly, the processor of the router 501 may obtain the relative orientation information of the notebook computer determined by the UWB module in the router 501.

It will be appreciated that if only the notebook computer 502 is connected to the router, there is no case where the directional radiation area of the antenna of the router cannot cover all the second electronic devices due to the large difference in the relative azimuth information of the plurality of second electronic devices. Based on this, in order to enable the router 501 to purposefully enhance the signal radiation intensity in the direction in which the notebook 502 is located, the processor of the router 501 may control the antenna to radiate in a directional radiation pattern.

Assuming that the second electronic device of the access router has a mobile phone in addition to the notebook computer 502, the router may determine, according to the relative direction information of the notebook computer and the mobile phone relative to the router, and the maximum radiation angle range of the antenna of the router under the directional radiation, whether the directional radiation range of the antenna can cover both the notebook computer and the mobile phone in the case that the antenna of the router adopts the directional radiation.

If the directional radiation range of the antenna of the router is judged to be capable of covering the notebook computer and the mobile phone, the router can control the antenna to radiate in a directional radiation mode. Meanwhile, the router can also combine the relative azimuth information of the mobile phone and the notebook computer to determine the directional radiation direction and the radiation intensity of the antenna, so that the radiation intensity of the antenna in the direction towards the notebook computer and the mobile phone is strongest, and the radiation intensity of the antenna can be reasonably controlled to reduce the power consumption of the router.

Of course, if the router determines that the radiation range area of the directional radiation cannot cover the mobile phone and the notebook computer at the same time when the directional radiation mode is adopted, in order not to influence the communication between the mobile phone and the notebook computer and the router, the antenna can be controlled to adopt the omnidirectional radiation mode to radiate signals.

It will be appreciated that the above description is given of the first electronic device as a router and the second electronic device as a notebook computer. However, in practical application, after the notebook computer is connected to the router, in order to better receive signals from the router and send signals to the router, the notebook computer can also be used as the first electronic device, and the router is used as the second electronic device.

For example, on the premise that the notebook computer is connected to the communication network only through the router, because only one router serving as the second electronic device is provided, the notebook computer can determine that the radiation mode of the antenna is a directional radiation mode, on the basis, the notebook computer can control the directional radiation direction and the radiation intensity in the directional radiation direction according to the relative azimuth information of the router relative to the notebook computer, so that the radiation of the antenna of the notebook computer in the direction facing the router is strongest, and the communication quality of the notebook computer and the router is improved.

Of course, the above is also applicable to a case where a router or a notebook computer has a plurality of antennas, and this is not limited thereto.

It will be appreciated that in the case of a first electronic device having multiple antennas, the present application may also control the radiation of each antenna individually. The following is a description with reference to fig. 6.

Fig. 6 is a schematic flow chart of another antenna control method according to an embodiment of the present application, where the method of the present embodiment is applied to a first electronic device, and the method of the present embodiment may include:

s601, at least one second electronic device establishing a wireless network connection with the first electronic device is determined.

The first electronic device is accessed to the communication network through the second electronic device, or the second electronic device is accessed to the communication network through the first electronic device.

S602, for each second electronic device, determining relative orientation information of the second electronic device relative to the first electronic device.

S603, determining respective working frequency bands of the at least one second electronic device.

The specific implementation of determining the working frequency band of the second electronic device may be referred to the foregoing description, and will not be described herein.

S604, for each second electronic device, determining an antenna suitable for establishing communication with the second electronic device from a plurality of antennas based on a frequency band interval respectively supported by the plurality of antennas in the first electronic device and the working frequency band of the second electronic device.

Wherein each antenna of the first electronic device may support at least one frequency band interval.

For example, each antenna in the first electronic device supports only one frequency band, and the frequency band supported by different antennas is different. Alternatively, each antenna of the first electronic device supports a plurality of different frequency bands, and of course, it is also possible that part of the antennas in the first electronic device support only one frequency band, and part of the antennas may support a plurality of frequency bands at the same time.

Wherein the at least one frequency band interval suitable for the antenna support of the second electronic device includes an operating frequency band of the second electronic device, so that the antenna can communicate with the second electronic device.

S605, for each antenna in the first electronic device, controlling radiation of the antenna according to the relative azimuth information of each second electronic device suitable for the antenna.

It will be appreciated that in the case where at least one second electronic device is connected to a first electronic device, the second electronic device to which the antenna is adapted may be zero or one or more for one antenna of the first electronic device.

Based on this, the present application can control the radiation of each antenna of the first electronic device based on the relative azimuth information of each second electronic device to which the antenna is suitable. And specific control of the radiation of a single antenna may be found in connection with any of the previous embodiments.

For example, an antenna radiation pattern for which the antenna is suitable may be determined based on the relative orientation information of the second electronic devices for which the antenna is suitable.

For another example, in the case where the antenna employs directional radiation, the directional radiation direction of the antenna is determined based on the relative direction information of the respective second electronic devices to which the antenna is adapted. Further, the radiation intensity of the antenna in the directional radiation direction is determined based on the relative distance information of the second electronic device to which each antenna is adapted.
