Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the embodiments of the present application, generally described and illustrated in the figures herein, can be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, presented in the accompanying drawings, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.

First, some terms in the present application are explained so as to be easily understood by those skilled in the art.

At present, due to the increase of frequency bands such as 5G, the number of antennas in electronic equipment is increased continuously, so that the antenna layout is difficult, and the efficiency is reduced. In order to reduce the influence of layout restrictions of the existing electronic device, different communication frequency bands may commonly share the same antenna, and in the electronic device 10 shown in fig. 1, wifi2.4g, N41, and N78 are integrated into the same antenna 11, that is, wifi2.4g, N41, and N78 share the antenna 11, where the frequency band of wifi2.4g is 2.412GHz to 2.472GHz, the frequency band of N41 is 2515MHz to 2675MHz, and the frequency band of N78 is 3400MHz to 3500 MHz. In addition, the antenna 11 may be Ant 61N 41 PRX + N78 DRX + wifi2.4gimo, where PRX is the primary set reception part and DRX is the diversity reception part.

However, sharing the same antenna by multiple different antenna bands may cause the antenna to resonate differently when being tuned, and different communication bands may share the same resonance, which may reduce antenna sideband efficiency. For example, when WIFI2.4G and N41 and WIFI2.4G and N78 work simultaneously, the antenna needs to cover two resonances of 2.4G-2.69G and 3.4G-3.6G frequency bands, respectively, and WIFI2.4G and N41 share the same resonance. Fig. 2 is a schematic diagram of resonance positions when the antenna covers wifi2.4g, N41 and N78 at the same time, and fig. 3 is a schematic diagram of efficiency when the antenna covers wifi2.4g, N41 and N78 at the same time. It can be known from comparing fig. 2 and fig. 3 that wifi2.4g and N41 share the same resonance, but sharing the resonance may cause the bandwidths of different communication bands to be difficult to be covered, and further cause the radiation efficiency of the antenna to be low.

In view of the above problems, the inventor proposes an antenna control method, an electronic device, and a storage medium according to embodiments of the present application, which can improve the frequency band efficiency of the target antenna to a certain extent by acquiring a resonant mode in different frequency bands when acquiring a working state of the electronic device in a first communication frequency band and a network-resident frequency band of the electronic device, and specifically, acquire the working state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device, and on this basis, if the electronic device works in the first communication frequency band and the network-resident frequency band of the electronic device does not belong to a second communication frequency band, control the target antenna to work in the first resonant mode, where a resonant bandwidth generated by the target antenna in the first resonant mode covers the first communication frequency band. In addition, if the electronic device does not operate in the first communication frequency band and the network-resident frequency band of the electronic device belongs to the second communication frequency band, the target antenna is controlled to operate in the second resonance mode, wherein the resonance bandwidth generated by the target antenna in the second resonance mode covers the second communication frequency band. This application not only can improve the frequency channel efficiency of antenna through acquireing different resonance modes, can improve the flexibility of antenna adjustment simultaneously. The specific antenna control method is described in detail in the following embodiments.

For another example: the front case 101 and the rear cover 102 may be a plastic case, a ceramic case, or the like.

The protective cover plate can be a glass cover plate, a sapphire cover plate, a plastic cover plate and the like, provides a protective effect for the display screen 22, prevents dust, water vapor or oil stains and the like from being attached to the display screen, avoids the corrosion of the external environment to the display screen 22, simultaneously prevents the impact force of the external environment to the display screen 22, and avoids the breakage of the display screen 22.

The protective cover may include a display area and a non-display area. The display area is transparent and corresponds to the light-emitting surface of the display screen 22. The non-display area is non-transparent to shield the internal structure of the electronic device. The non-display area may be provided with openings for sound and light transmission.

Referring to fig. 5, fig. 5 is a flowchart illustrating an antenna control method according to an embodiment of the present application. In a specific embodiment, the antenna control method is applied to the antenna control apparatus 400 shown in fig. 15 and to the electronic device 500 shown in fig. 17. As will be described in detail with respect to the flow shown in fig. 1, the antenna control method may specifically include steps 110 to S130.

Step S110: and acquiring the working state of the electronic equipment under the first communication frequency band and the network-resident frequency band of the electronic equipment.

The embodiment of the application can be applied to electronic equipment, and the electronic equipment can be an electronic equipment which can run an application program, such as a smart phone, a tablet computer, an electronic book and the like. In addition, the electronic device may include a target antenna to support multiplexing of at least the first communication band and the second communication band.

As a mode, in the embodiment of the present application, an operating state of the electronic device in the first communication frequency band may be obtained, where the operating state of the electronic device in the first communication frequency band may include that the electronic device operates in the first communication frequency band, or may also include that the electronic device does not operate in the first communication frequency band. The first communication frequency band may belong to a first communication network, and the first communication network may be a wireless network. For example, the first communication network may be WiFi.

In other embodiments, the network-resident frequency band of the electronic device may be obtained according to an embodiment of the present application, where the network-resident frequency band may be a frequency band of a second communication network to which the electronic device is connected, that is, the second communication network may include the second communication frequency band, or may include other communication frequency bands other than the second communication frequency band, and meanwhile, the second communication network may be a mobile communication network. For example, the mobile communication network may be 4G or 5G, etc.

As a mode, before acquiring the operating state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device, the embodiment of the present application may determine whether the electronic device is in the network-connected state. When the electronic device is in a networking state, the working state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device can be acquired.

In other words, when the electronic device is in the networking state, the network to which the electronic device is connected may be a wireless network, a mobile network, or a shared network connection triggered by the mobile network. For example, when the network-resident frequency band of the electronic device is determined to be wifi2.4+ N41, the network to which the electronic device is connected is a shared network. In addition, the same network may include a plurality of different network-resident frequency bands, and the frequency band ranges of the network-resident frequency bands may be different.

As a manner, before obtaining the operating state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device, in the embodiment of the present application, a plurality of historical network-resident frequency bands may also be obtained, and whether the network-resident frequency band of the electronic device is a stable frequency band is determined based on the plurality of historical network-resident frequency bands, where the stable frequency band refers to that the radiation efficiency of the antenna of the electronic device is stable and better in the network-resident frequency band. If the network-resident frequency band of the electronic equipment is determined to be a stable frequency band, the network-resident frequency band of the electronic equipment can be continuously monitored, so that power consumption caused by frequency band adjustment can be reduced.

As another mode, if it is determined that the network-resident frequency band of the electronic device is not a stable frequency band, the operating state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device may be acquired. In addition, when the working state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device are obtained, the position of the electronic device can be located, then whether the current network-resident frequency band of the electronic device is stable or not is determined by combining the position information and the historical network-resident frequency band, and if the current network-resident frequency band of the electronic device is not stable, the working mode of the target antenna can be changed.

As a manner, after acquiring the operating state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device, in the embodiment of the present application, it may be determined whether the operating state and the network-resident frequency band of the electronic device satisfy a first condition, and if the first condition is satisfied, step S120 is executed, where the first condition may be that the electronic device operates in the first communication frequency band, and the network-resident frequency band of the electronic device does not belong to the second communication frequency band. In addition, if the operating state and the network-resident frequency band of the electronic device do not satisfy the first condition, it may be determined whether the operating state and the network-resident frequency band satisfy a second condition, and if the operating state and the network-resident frequency band satisfy the second condition, step S130 is executed, where the second condition may be that the electronic device does not operate in the first communication frequency band, and the network-resident frequency band of the electronic device belongs to the second communication frequency band. Specifically, the first condition or the second condition is determined first, and the determination is not specifically limited herein and may be selected according to actual situations.

Step S120: and if the electronic equipment works in the first communication frequency band and the network-resident frequency band of the electronic equipment does not belong to the second communication frequency band, controlling the target antenna to work in a first resonance mode.

As a mode, when the operating state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device are obtained, the electronic device may determine whether the electronic device operates in the first communication frequency band according to the operating state, and determine whether the network-resident frequency band of the electronic device does not belong to the second communication frequency band based on the network-resident frequency band of the electronic device. And if the electronic equipment is determined to work in the first communication frequency band and the network-resident frequency band of the electronic equipment does not belong to the second communication frequency band, controlling the target antenna to work in the first resonance mode.

In the embodiment of the application, the resonance bandwidth generated by the target antenna in the first resonance mode can cover the first communication frequency band. In addition, the first communication band may belong to a first communication network and the second communication band may belong to a second communication network, i.e. the first communication band and the second communication band may belong to two different communication networks, and the target antenna may support multiplexing of the first communication band and the second communication band. In addition, the first communication network may be a WiFi network, the first communication band may be a WiFi2.4G band, the second communication network may be a mobile communication network, and the second communication band may be an N41 or B41 band.

As an example, when the operating state of the electronic device in the WiFi2.4G frequency band and the network-resident frequency band of the electronic device are acquired, in the embodiment of the present application, it may be determined whether the electronic device operates in the WiFi2.4G frequency band, and whether the network-resident frequency band of the electronic device belongs to the N41 or the B41 frequency band, and if the electronic device operates in the WiFi2.4G frequency band and the network-resident frequency band of the electronic device does not belong to the N41 or the B41 frequency band, at this time, the target antenna may be controlled to operate in the first resonance mode. And the resonance bandwidth generated by the target antenna in the first resonance mode can cover the WiFi2.4G frequency band.

Step S130: and if the electronic equipment does not work in the first communication frequency band and the network-resident frequency band of the electronic equipment belongs to the second communication frequency band, controlling the target antenna to work in a second resonance mode.

As a mode, when the working state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device are obtained, the electronic device may determine whether the electronic device works in the first communication frequency band according to the working state, and determine whether the network-resident frequency band of the electronic device belongs to the second communication frequency band. And if the electronic equipment is determined not to be operated in the first communication frequency band and the network-resident frequency band of the electronic equipment belongs to the second communication frequency band, controlling the target antenna to operate in the second resonance mode.

In this embodiment, the resonance bandwidth generated by the target antenna in the second resonance mode can cover the second communication frequency band. In addition, the first communication band may belong to a first communication network and the second communication band may belong to a second communication network, i.e. the first communication band and the second communication band may belong to two different communication networks, and the target antenna may support multiplexing of the first communication band and the second communication band. In addition, the first communication network may be a WiFi network, the first communication frequency band may be a WiFi2.4G frequency band, the second communication network may be a mobile communication network, and the second communication frequency band may be an N41 or B41 frequency band.

As an example, when the operating state of the electronic device in the WiFi2.4G frequency band and the network-resident frequency band of the electronic device are acquired, in the embodiment of the present application, it may be determined whether the electronic device operates in the WiFi2.4G frequency band, and whether the network-resident frequency band of the electronic device belongs to the N41 or the B41 frequency band, and if the electronic device does not operate in the WiFi2.4G frequency band and the network-resident frequency band of the electronic device belongs to the N41 or the B41 frequency band, at this time, the target antenna may be controlled to operate in the second resonance mode. Wherein, the resonance bandwidth generated by the target antenna in the second resonance mode can cover the N41 or B41 frequency band. The second communication band may be B1, B3, B40, or the like.

It should be noted that the first communication network and the second communication network may also be other networks, and as long as the frequency bands in the first communication network and the second communication network may share the same resonance, or the communication frequency band in the first communication network and the communication frequency band in the second communication network may be multiplexed, the resonant frequency of the antenna according to the embodiment of the present application may be used for adjustment, and specific inclusion of which frequency bands is not described here in detail.

As a manner, when the working state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device are acquired, in the embodiment of the present application, it may also be determined whether the working state of the electronic device and the network-resident frequency band satisfy a third condition, and if the third condition is satisfied, the target antenna is controlled to operate in a third resonance mode. The third condition may be that the electronic device does not operate in the first communication frequency band of the first communication network, and the network-resident frequency band of the electronic device does not belong to the third communication frequency band of the second communication network. In this embodiment of the application, a resonance bandwidth generated by the target antenna in the third resonance mode covers a third communication frequency band, where the third communication frequency band is a frequency band outside the second communication frequency band in all communication frequency bands of the second communication network.

As another mode, when the working state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device are acquired, in the embodiment of the present application, it may also be determined whether the working state of the electronic device and the network-resident frequency band satisfy a fourth condition, and if the fourth condition is satisfied, the target antenna is controlled to operate in a fourth resonance mode. The fourth condition may be that the electronic device operates in the first communication frequency band of the first communication network, and the network-resident frequency band of the electronic device belongs to the second communication frequency band of the second communication network. In addition, the resonance bandwidth generated by the target antenna in the fourth resonance mode covers the first communication frequency band and the second communication frequency band.

It should be noted that, when the working state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device are obtained, in the embodiment of the present application, it may be determined first whether the working state of the electronic device and the network-resident frequency band satisfy the first condition, or it may also be determined first whether the working state of the electronic device and the network-resident frequency band satisfy the second condition, the third condition, or the fourth condition. Specifically, which condition is determined first, and which condition is determined later is not specifically limited, and may be selected according to actual conditions.

According to the antenna control method provided by the embodiment of the application, when the working state of the electronic device under the first communication frequency band and the network-resident frequency band of the electronic device are obtained, the frequency band efficiency of the target antenna can be improved to a certain extent by obtaining the resonance modes under different frequency bands, specifically, the working state of the electronic device under the first communication frequency band and the network-resident frequency band of the electronic device are obtained, on the basis, if the electronic device works in the first communication frequency band and the network-resident frequency band of the electronic device does not belong to the second communication frequency band, the target antenna is controlled to work in the first resonance mode, and the resonance bandwidth generated by the target antenna under the first resonance mode covers the first communication frequency band. In addition, if the electronic device does not operate in the first communication frequency band and the network-resident frequency band of the electronic device belongs to the second communication frequency band, the target antenna is controlled to operate in the second resonance mode, wherein the resonance bandwidth generated by the target antenna in the second resonance mode covers the second communication frequency band. This application not only can improve the frequency channel efficiency of antenna through acquireing different resonance modes, can improve the flexibility of antenna adjustment simultaneously.

Referring to fig. 6, the antenna control method according to another embodiment of the present application may include steps S210 to S240.

Step S210: and acquiring the working state of the electronic equipment under the first communication frequency band and the network-resident frequency band of the electronic equipment.

Step S220: and if the electronic equipment works in the first communication frequency band and the network-resident frequency band of the electronic equipment does not belong to the second communication frequency band, controlling the target antenna to work in a first resonance mode.

In this embodiment, the target antenna may include a tuning circuit, which may also be referred to as a frequency modulation switch, and the tuning circuit is mainly configured to control the target antenna to operate in a target resonance mode, that is, the tuning circuit is configured to adjust a resonance mode of the target antenna, where the target resonance mode may include a first resonance mode. Wherein the tuning circuit may comprise a plurality of inductors. The target resonant modes are different, and the number of inductors conducted in the corresponding tuned circuits may also be different.

In order to better understand the relationship between the tuning circuit and the target antenna, the embodiments of the present application provide schematic diagrams as shown in fig. 7 and fig. 8, where fig. 7 may be an antenna schematic diagram obtained by adding the tuning circuit 212 to the target antenna shown in fig. 1, and the tuning circuit 212 may be installed between the feeding point position 213 and the feeding point spring pin position of the target antenna 211; fig. 8 is a schematic diagram of a matching network (not shown in fig. 7) including a tuning circuit, and it is seen from fig. 8 that the tuning circuit 212 may include a plurality of inductors, and by connecting different inductors, the embodiments of the present application may achieve adjustment of the resonant mode of the target antenna and adjustment of the resonant frequency of the target antenna.

Specifically, in the embodiment of the application, when it is determined that the electronic device operates in the first communication frequency band and the network-resident frequency band of the electronic device does not belong to the second communication frequency band, and the target antenna is controlled to operate in the first resonance mode, a first specified number of inductors may be selected from the plurality of inductors in the tuning circuit and turned on, so as to obtain the first tuning circuit. On the basis, the target antenna is controlled to work in a first resonance mode based on the first tuning circuit. It can be seen that, if the operating state of the electronic device in the first communication frequency band and the network-resident frequency band of the electronic device are different, the number of the inductors conducted in the tuning circuit may also be different.
