The embodiment of the present application provides an electronic device, where the electronic device may include, but is not limited to, at least one of a mobile phone, a tablet computer, and a wearable device, and the embodiment of the present application is described by taking the electronic device as a mobile phone, and other types of electronic devices may be executed by reference.
Referring to fig. 1, a schematic structural diagram of an electronic device according to an embodiment of the present application is shown, and referring to fig. 2, a schematic structural diagram of an antenna assembly according to an embodiment of the present application is shown. Specifically, the electronic device may specifically include:
a gesture detector (not shown) for acquiring a gesture of the electronic device;
the antenna assembly 10 comprises a first antenna 11 and a second antenna 12 which are arranged at intervals, wherein the first antenna 11 is coupled with the second antenna 12, and when a feed signal is in a preset frequency band, the first antenna 11 radiates to generate a first resonance, and the second antenna 12 radiates to generate a second resonance; and
the resonance control module 13, the resonance control module 13 is electrically connected with the first antenna 11 and the attitude detector respectively; the resonance control module 13 may be configured to control the first antenna 11 or the second antenna 12 as a main radiating antenna in the preset frequency band based on the gesture.
In the embodiment of the present application, because the antenna assembly 10 of the electronic device includes the first antenna 11 and the second antenna 12 that are coupled, when the feed signal is the preset frequency band, the radiation of the first antenna 11 may generate the first resonance, and the radiation of the second antenna 12 may generate the second resonance, therefore, in the preset frequency band, the antenna assembly 10 may implement dual resonance, improve the bandwidth of the antenna, and improve the efficiency of the antenna.
Also, by the posture detector, the posture of the electronic device can be acquired. Because the resonance control module 13 is connected to the attitude detector, the resonance control module 13 can determine the area where the electronic device is held according to the attitude, and control the first antenna 11 or the second antenna 12 to be the main radiation antenna in the preset frequency band according to different holding areas, so as to reduce the loss of the antenna performance caused by the user holding, and enable the antenna assembly 10 to show better antenna performance in any attitude.
As shown in fig. 2, the first antenna 11 may include: the antenna comprises a first antenna body 111, a feeding part 112 and a first grounding part 113, wherein the feeding part 112 and the first grounding part 113 are electrically connected with the first antenna body 111; the second antenna 12 may include: a second antenna body 121 and a second grounding part 122, the second grounding part 122 is electrically connected with the second antenna body 121, and the second antenna body 121 is coupled with the first antenna body 111.
In practical applications, the first antenna 11 may serve as a feed antenna for the antenna assembly 11. The first antenna body 111 may serve as a radiation main body of the antenna 11, and the first antenna body 111 may include, but is not limited to, any one of a metal frame, a flexible circuit board, and a Laser-Direct-structuring (LDS) antenna, which is not limited in this application.
Specifically, the feeding unit 112 may serve as a feeding component of the antenna 11, and support at least one of Sub-6G and millimeter waves to meet the requirement of the fifth generation mobile communication technology (5G). In the embodiment of the present application, only the power feeding unit 112 supporting the Sub 6G system will be described as an example. Specifically, Sub 6G may be Sub-6G, which refers to a 5G band, and the operating frequency is in a band below 6G of 450MHz-6000MHz, for example, N41(2500MHz-2690MHz), N78(3400MHz-3600MHz), N79(4800MHz-5000MHz), and the like.
Specifically, the first ground portion 113 may serve as a ground part of the antenna 11. The first ground part 113 may be optional, and when the first antenna 11 is a monopole antenna, the first ground part 113 may not be present; the first ground part 113 may be present in case the first antenna 11 is a bore antenna, e.g. a PIFA/IFA antenna. In practical applications, the first grounding portion 113 may be above the power feeding portion 112 or below the power feeding portion 112, and the specific positions of the first grounding portion 113 and the power feeding portion 112 in the embodiments of the present application may not be limited.
In the embodiment of the present application, the second antenna 12 may be used as a parasitic antenna (coupled antenna) of the antenna assembly 11. The second antenna body 121 may be disposed at a distance from the first antenna body 111 to achieve coupling between the second antenna body 121 and the first antenna body 111. By the coupling between the second antenna body 121 and the first antenna body 111, the bandwidth of the antenna assembly 10 can be widened. Specifically, the second antenna body 121 may include, but is not limited to, any one of a metal frame, a flexible circuit board, and an LDS antenna, which is not limited in this embodiment. The second grounding portion 122 is electrically connected to the second antenna body 121, so as to realize grounding of the second antenna body 121.
In practical applications, some metal components directly below the first antenna body 111 need to be hollowed out as thin as possible so that the first antenna body 111 can perform antenna radiation. Similarly, some metal parts directly below the second antenna body 121 need to be hollowed as thin as possible so that the second antenna body 121 performs antenna radiation, and thus, the antenna height and the clearance can be improved.
Referring to fig. 3, showing one of the operation states of the antenna assembly of the embodiment of the present application, referring to fig. 4, showing the second operation state of the antenna assembly of the embodiment of the present application, as shown in fig. 3 and 4, since the first antenna 11 is coupled to the second antenna 12, the first antenna 11 may generate the first resonance a and the second antenna 12 may generate the second resonance B in the predetermined frequency band (N41 frequency band). Thus, in the N41 frequency band, the antenna assembly 10 can realize dual resonance, thereby improving the bandwidth of the antenna and further improving the performance of the antenna.
It should be noted that, in the embodiment of the present application, the preset frequency band is only an N41 frequency band for example, in practical applications, the preset frequency band may also be an N78 frequency band, an N79 frequency band, and the specific frequency band of the preset frequency band is not limited in the embodiment of the present application.
As shown in fig. 1, the electronic device may include a device body 14, and the device body 14 may include a first side and a second side disposed away from each other; the attitude detector is arranged in the equipment body 14, and the first antenna 11 and the second antenna 12 are arranged on the second side of the equipment body 14; the first antenna 11 may be disposed near the top of the apparatus body 14, and the second antenna 11 may be disposed below the first antenna 11.
In this embodiment, the posture of the electronic device may include a landscape state and a non-landscape state, and the non-landscape state may specifically include a portrait state and any free state except the landscape state and the portrait state. The attitude detector may be a gravity sensor, a level, or the like capable of detecting the attitude of the electronic device. Specifically, the gesture detector may be disposed in the electronic device, and the gesture of the electronic device may be acquired by the gesture detector to determine whether the electronic device is in a landscape state or a non-landscape state.
As shown in fig. 1, since the first antenna 11 may be disposed near the top of the electronic device, the second antenna 11 may be disposed at a lower side of the first antenna 11. In this way, when the electronic apparatus is in the non-landscape state, the first antenna 11 and the second antenna 12 are not easily held by the hand of the user, and therefore the radiation performance of the first antenna 11 and the second antenna 12 is not easily blocked by the hand of the user. In this case, since the radiation performance of the first antenna 11 as the feeding antenna is generally better than that of the second antenna as the parasitic antenna, the resonance control module 13 may control the first antenna 11 as the main radiation antenna in the preset frequency band (as shown in fig. 3), so that the electronic device exhibits better antenna performance in the non-landscape state.
As shown in fig. 3, in the case where the first antenna 11 serves as a main radiation antenna, the part of the N41 frequency band falling within the first resonance a is larger than the part falling within the second resonance B, and the N41 frequency band substantially falls within the first resonance a, at which time the first antenna 11 that generates the first resonance a can serve as a main radiation antenna.
In practical application, when the posture of the electronic device is in a landscape state, because the first antenna 11 is close to the top of the electronic device, the first antenna 11 is easier to be held by the hand of the user, the radiation performance of the first antenna 11 is easier to be shielded by the hand of the user and has radiation loss, and the second antenna 12 is not easy to be held by the hand of the user, the radiation performance of the second antenna 12 is not easy to be shielded by the hand of the user. In this case, in order to reduce the influence of the antenna loss caused by the user holding the electronic device on the antenna performance, the resonance control module 13 may control the second antenna 11 as a main radiation antenna in the preset frequency band (as shown in fig. 4), so that the electronic device exhibits better antenna performance in the landscape state.
As shown in fig. 4, in the case where the second antenna 12 functions as a main radiation antenna, the part of the N41 frequency band falling within the second resonance B is larger than the part falling within the first resonance a, and the N41 frequency band substantially falls within the second resonance B, at which time the second antenna 12 that generates the second resonance B can function as a main radiation antenna. Since the radiation performance of the second antenna 12 is not easily shielded by the hand of the user, the influence of the holding of the user on the antenna performance of the electronic device in the landscape state is small, and the electronic device has good antenna performance.
In the embodiment of the present application, when the posture of the electronic device is in the non-landscape state, the first antenna 11 with better radiation performance may be used as a main radiation antenna, so that the electronic device shows better antenna performance in the non-landscape state. Under the condition that the posture of the electronic equipment is in the landscape screen state, the second antenna 12, the radiation performance of which is not easily affected by the shielding of the hand of the user, can be used as a main radiation antenna, so that the antenna performance of the electronic equipment in the landscape screen state is less affected by the holding of the user, and better antenna performance is shown. Thus, the antenna assembly 10 of the electronic device described herein may exhibit good antenna performance at any position.
In some optional embodiments of the present application, the resonance control module 13 may include: a switch submodule 131, a first resonance submodule 132 and a second resonance submodule 133; one end of the switch submodule 131 is electrically connected to one end of the first resonance submodule 132 and one end of the second resonance submodule 133, respectively; the other end of the first resonance sub-module 132 and the other end of the second resonance sub-module 133 are respectively connected with the first antenna 11; the switch submodule 131 may be configured to, based on the gesture, control one end of the switch submodule 131 to be conducted with one of the first resonant submodule 132 and the second resonant submodule 133, so that the first antenna 11 or the second antenna 12 serves as a main radiating antenna in the preset frequency band.
Specifically, the switch sub-module 131 may be a switch chip, and a switch power supply control circuit, an on-off control logic circuit of a switch, and the like may be integrated on the switch chip. The first and second resonant sub-modules 132 and 133 may have a resonant circuit integrated thereon, and the resonant circuit has an inductor or a capacitor disposed therein for adjusting a resonant frequency and a resonant wave. In practical applications, the first resonant submodule 132 and the second resonant submodule 133 can be used to adjust the resonance between the first antenna 11 and the second antenna 12, and the resonance adjusting effect can be different. When the switch sub-module 131 is connected to one of the first resonant sub-module 132 and the second resonant sub-module 133, one of the first antenna 11 and the second antenna 12 may be used as a main radiating antenna in the preset frequency band, and when the switch sub-module 131 is connected to the other of the first resonant sub-module 132 and the second resonant sub-module 133, the other of the first antenna 11 and the second antenna 12 may be used as a main radiating antenna in the preset frequency band. In this way, the switch submodule 131 controls the on/off of the first resonance submodule 132 and the second resonance submodule 133, so that the antenna state of the electronic device can be changed, the first antenna 11 or the second antenna 12 is used as a main radiation antenna in the preset frequency band, and the control logic is simple.
Specifically, when the posture of the electronic device is in the non-landscape state, the other end of the switch submodule 131 is connected to the first resonance submodule 132, and the other end of the switch submodule 131 is disconnected from the second resonance submodule 133, so that the first antenna 11 serves as a main radiation antenna in the preset frequency band. Under the condition that the posture of the electronic device is in the landscape state, the switch submodule 131 is connected with the second resonance submodule 133, and the switch submodule 131 is disconnected with the first resonance submodule 132, so that the second antenna 12 serves as a main radiation antenna in the preset frequency band.
As shown in fig. 4, the other end of the switch submodule 131 is grounded; the other end of the first resonant submodule 132 and the other end of the second resonant submodule 133 are respectively connected to the first antenna body 111 and connected to different positions of the first antenna body 111. In this way, different resonance adjustment effects can be achieved when the first resonance module 132 and the second resonance module 133 are respectively turned on.
Specifically, in the case where the switch sub-module 131 is directly grounded, the resonance control module 13 may be connected to the first antenna 11 as a separate module, so as to facilitate testing and maintenance of the resonance control module 13.
In some optional implementations of the embodiments of the present application, the other end of the switch submodule 131 is electrically connected to the feeding portion 112; the other end of the first resonant submodule 132 and the other end of the second resonant submodule 133 are electrically connected to the first antenna body 111, respectively.
Specifically, under the condition that the other end of the switch sub-module 131 is electrically connected to the feeding portion 112, and the other end of the first resonance sub-module 132 and the other end of the second resonance sub-module 133 are electrically connected to the first antenna body 111, respectively, the resonance control module 13 may be connected in series in the feeding portion 112, so that an extra space is prevented from being provided in the electronic device to arrange the resonance control module 13, and the internal space of the electronic device is saved.
Optionally, the electronic device may further include: and the key 15 is arranged on the second side of the equipment body 14, and the key 15 is connected with the equipment body 14.
In this embodiment of the application, because the side key 15 is disposed at the second side of the device body 14, the first antenna 11 and the second antenna 12 are disposed at the first side of the device body 14, that is, the side key 15 is disposed at different sides of the device body 14 from the first antenna 11 and the second antenna 12, so that the layout of the first antenna 11 and the second antenna 12 is prevented from being limited by the side key 15, the layout space of the first antenna 11 and the second antenna 12 is increased, and further, the antenna performance of the electronic device can be further improved.
In summary, the electronic device according to the embodiment of the present application may include at least the following advantages:
in the embodiment of the application, because the antenna module of the electronic device includes the first antenna and the second antenna that are coupled, when the feed signal is for predetermineeing the frequency channel, the first antenna radiation can produce first resonance, the second antenna radiation can produce the second resonance, therefore, predetermine the frequency channel, the antenna module can realize double resonance, improves the bandwidth of antenna, promotes the efficiency of antenna. Also, by the posture detector, the posture of the electronic device can be acquired. The resonance control module can judge the area where the electronic equipment is held according to the postures, and control the first antenna or the second antenna to be used as the main radiation antenna in the preset frequency band according to different holding areas, so that the loss of the antenna performance when a user holds the antenna is reduced, and the antenna assembly can show better antenna performance in any posture.
