[0035] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] The present application embodiment provides an electronic device, Figure 1 A schematic diagram of the structure of an optional electronic device provided in an embodiment of the present application, such as Figure 1 As shown, the electronic device 100 includes an antenna assembly 11, and the antenna assembly 11 includes: a first antenna unit 111, a metal decoration 112 and a tuning circuit 113; wherein one end of the tuning circuit 113 is connected to the metal decoration 112; wherein,

[0037] The first antenna unit 111 is used to generate a resonance point of a first frequency;

[0038] The metal decoration part 112 is used to generate a resonance point of a second frequency point.

[0039] In view of the influence of metal decorations on antenna performance, in the related art, multi-point grounding of metal decorations is used to reduce the influence of metal decorations on antennas. Figure 2 Schematic diagram of the structure of the antenna 1 and the metal decorative part in the electronic device in the related art Figure 1 ,like Figure 2 As shown, the antenna 1 is an antenna distributed in the frame of the electronic device. The antenna 1 is affected by the metal decoration. In order to reduce the influence of the metal decoration on the antenna 1, multiple locations of the metal decoration are directly grounded. In addition, in order to reduce the influence of the metal decoration on the antenna 1, the antenna layout that overlaps with the resonance frequency of the metal decoration can also be kept away. Figure 3 Schematic diagram of the structure of the antenna 1 and the metal decorative part in the electronic device in the related art Figure 2 ,like Figure 3 As shown, antenna 1 is placed at a location far away from antenna 1.

[0040] In addition, in order to reduce the antenna directivity coefficient, methods such as increasing parasitic (directing) branches, increasing the antenna radiation area, and placing the antenna in a fixed position with a good electronic device environment can be used. However, grounding the metal decorative parts at multiple points makes it appear as a floor to the antenna 1, but this will couple the energy of the antenna 1 and reduce the antenna efficiency. In addition, according to the size of the metal decorative parts, the antenna 1, which may be more affected by it, is placed at a farther distance, but this will limit the overall layout of the electronic device. On the other hand, the methods of reducing the antenna directivity coefficient by increasing parasitic (directing) branches, increasing the antenna radiation area, and placing the antenna 1 in a fixed position at the end of the electronic device all have requirements for the layout space and environment of the electronic device and are subject to many restrictions.

[0041] In order to ensure the antenna performance of the antenna while improving the influence of the metal decorative parts, in an embodiment of the present application, in the electronic device 100, the antenna component 11 is under the influence of the metal decorative part 112 on the first antenna unit 111. In order to improve the influence of the metal decorative part 112 on the first antenna unit 111 while ensuring the antenna performance of the first antenna unit 111, a tuning circuit 113 is connected to the metal decorative part 112, so that the feeding point of the first antenna unit 111 is connected to the feed source to receive the excitation signal, and transmit the excitation signal to the radiator of the first antenna unit 111, so that the first antenna unit 111 generates a resonance point of a first frequency, and the metal decorative part 112 generates a resonance point of a second frequency, wherein the first frequency is located in the first working frequency band of the antenna component 11; the second frequency is located in the first working frequency band or the second frequency is located outside the first working frequency band.

[0042] That is, after adding a tuning circuit 113 connected to the metal decorative part 112, after tuning of the tuning circuit 113, the antenna assembly 11 may include at least the following three technical solutions:

[0043] The first technical solution is: the first antenna unit 111 is used to generate a resonance point of a first frequency, and the metal decorative part 112 is used to generate a resonance point of a second frequency. The first frequency is located within the first working frequency band of the antenna component 11, and the second frequency is located within the first working frequency band of the antenna component 11; that is, under the action of the tuning circuit 113, the first frequency and the second frequency are both located within the first working frequency band.

[0044] The second technical solution is: the first antenna unit 111 is used to generate a resonance point of a first frequency, and the metal decorative part 112 is used to generate a resonance point of a second frequency, the first frequency point is located within the first working frequency band of the antenna component 11, and the second frequency band is located outside the first working frequency band of the antenna component 11; that is, under the action of the tuning circuit 113, the first frequency point is located within the first working frequency band, and the second frequency point is located outside the first working frequency band.

[0045] The third technical solution is: the first antenna unit 111 is used to generate a resonance point of a first frequency, and the metal decorative part 112 is used to generate a resonance point of a second frequency, the first frequency is located in the first working frequency band of the antenna component 11, the second frequency is located in the first working frequency band of the antenna component 11, or the second frequency is located outside the first working frequency band of the antenna component 11; that is, the tuning circuit 113 can achieve switching, and through switching, the first frequency is located in the first working frequency band, and the second frequency is either located in the first working frequency band or outside the first working frequency band.

[0046] Among them, the above-mentioned first working frequency band is a working frequency band of the antenna component 11. Of course, the antenna component 11 can also include other working frequency bands. Here, the embodiment of the present application does not make specific limitations on this.

[0047] For the first working frequency band, when the antenna assembly 11 only includes the first antenna unit 111, the first antenna unit 111 is used to generate the second working frequency band. For the second frequency point located within the first working frequency band, the bandwidth of the first working frequency band is extended compared to the second working frequency band. For the second frequency point located outside the first working frequency band, the first working frequency band is equivalent to the second working frequency band.

[0048] It can be seen that the first frequency point generated by the first antenna unit 111 belongs to the first working frequency band of the antenna assembly 11, and the second frequency point generated by the metal decorative part 112 can belong to the first working frequency band or a point outside the first working frequency band. In this way, when the first frequency point and the second frequency point both belong to the first working frequency band, the bandwidth of the second working frequency band of the first antenna unit 111 is increased to obtain the first working frequency band. When the second frequency point is not within the first working frequency band where the first frequency point is located, but is outside the first working frequency band, the influence of the metal decorative part 112 on the first antenna unit 111 is reduced. In this way, the antenna performance of the first antenna unit 111 is guaranteed while the influence of the metal decorative part 112 is improved.

[0049] The first antenna unit 111 may be an antenna distributed on the frame of the electronic device 100 , and the metal decoration part 112 is an antenna that is close to the first antenna unit 111 and thus affects the first antenna unit 111 .

[0050] In addition, the tuning circuit 113 may be connected to any position of the metal decorative part 112. The metal decorative part 112 may be of a regular shape, such as a circle, a rectangle, etc., or of an irregular shape. The embodiment of the present application does not specifically limit this.

[0051] In the above-mentioned antenna assembly 11, in addition to the above-mentioned first antenna unit 111, other antenna units may also be included, and the embodiment of the present application does not make any specific limitation on this.

[0052] It should be noted that, with respect to the situation in which the second frequency point is located outside the first working frequency band in the above-mentioned second technical solution and the third technical solution, the metal decorative part 112 generates a resonance point of the second frequency point, thereby generating a resonance mode of a frequency band including the second frequency point. The farther the frequency band is from the first working frequency band, the smaller the impact on the first working frequency band. The antenna performance of the first antenna unit 111 is guaranteed while improving the impact of the metal decorative part 112.

[0053] For the above tuning circuit 113, different tuning circuit structures correspond to the above different technical solutions. In an optional embodiment, when the tuning circuit 113 is a first tuning circuit, the second frequency point is located within the first working frequency band;

[0054] When the tuning circuit 113 is a second tuning circuit, the second frequency point is outside the first working frequency band;

[0055] When the tuning circuit 113 is a third tuning circuit, the second frequency point is located within the first working frequency band or the second frequency point is located outside the first working frequency band.

[0056] It can be understood that the above-mentioned tuning circuit 113 can include at least three types, namely a first tuning circuit, a second tuning circuit and a third tuning circuit. When the tuning circuit 113 adopts the first tuning circuit, corresponding to the first technical solution, the first frequency point generated by the first antenna unit 111 is located in the first working frequency band, and the second frequency band generated by the metal decorative part 112 is located in the first working frequency band.

[0057] When the tuning circuit 113 adopts the second tuning circuit, corresponding to the second technical solution, the first frequency point generated by the first antenna unit 111 is located in the first working frequency band, and the second frequency point generated by the metal decorative part 112 is located outside the first working frequency band.

[0058] When the tuning circuit 113 adopts the third tuning circuit, corresponding to the third technical solution, the first frequency point generated by the first antenna unit 111 is located within the first working frequency band, and different states of the third tuning circuit make the second frequency point generated by the metal decorative part 112 located within the first working frequency band, or the second frequency point is located outside the first working frequency band.

[0059] With respect to the first tuning circuit, in an optional embodiment, the first tuning circuit includes: a first inductor; wherein one end of the first inductor is connected to the metal decoration part 112, and the other end of the first inductor is grounded.

[0060] It can be understood that the inductance value of the first inductor is adjusted and determined so that resonance occurs within the first working frequency band of the metal decorative part 112. Then, for the first antenna unit 111, the metal decorative part 112 achieves a parasitic loading effect, and the second frequency point generated by the metal decorative part 112 is located within the first working frequency band. Compared with the working frequency band of the first antenna unit 111 when the tuning circuit 113 is not added, the bandwidth of the working frequency band of the first antenna unit 111 is expanded, and the expanded working frequency band is the above-mentioned first working frequency band.

[0061] For the second tuning circuit, in an optional embodiment, the second tuning circuit includes: a first inductor, a second inductor and a first capacitor; wherein, one end of the first inductor, one end of the second inductor and one end of the first capacitor are connected to the metal decorative part 112, and the other end of the first inductor, the other end of the second inductor and the other end of the first capacitor are grounded.

[0062] It can be understood that the inductance value of the first inductor, the inductance value of the second inductor and the capacitance value of the first capacitor are adjusted to determine the inductance value of the first inductor, the inductance value of the second inductor and the capacitance value of the first capacitor, so that the resonance point generated by the metal decorative part 112 is away from the first operating frequency band, the metal decorative part 112 is an equivalent high impedance, and the second frequency point generated by the metal decorative part 112 is outside the first operating frequency band. Compared with the first operating frequency band including the first frequency point generated by the first antenna unit 111, the resonance point is away from the first operating frequency band, thereby reducing the influence of the metal decorative part 112 on the first antenna unit 111.

[0063] For the third tuning circuit, in an optional embodiment, the third tuning circuit includes: a first inductor, a second inductor, a first capacitor and a switch; wherein one end of the first inductor and a fixed end of the switch are connected to the metal decorative part 112, the other end of the first inductor is grounded, one end of the second inductor and one end of the first capacitor are connected to the moving end of the switch, and the other end of the second inductor and the other end of the first capacitor are grounded;

[0064] in,

[0065] When the switch is in an off state, the second frequency point is within the first operating frequency band;

[0066] When the switch is in a closed state, the second frequency point is outside the first operating frequency band.

[0067] It can be understood that when the switch is in a closed state and an open state, the inductance value of the first inductor, the inductance value of the second inductor and the capacitance value of the first capacitor are adjusted to determine the inductance value of the first inductor, the inductance value of the second inductor and the capacitance value of the first capacitor, so that when the switch is in an open state, the second frequency point generated by the metal decorative part 112 is located within the first working frequency band, and compared with the working frequency band of the first antenna unit 111 when the tuning circuit 113 is not added, the bandwidth of the working frequency band of the first antenna unit 111 is expanded, and the expanded working frequency band is the above-mentioned first working frequency band.

[0068] When the switch is in a closed state, the resonance point generated by the metal decorative part 112 is far away from the first operating frequency band, the metal decorative part 112 is an equivalent high impedance, and the second frequency point generated by the metal decorative part 112 is outside the first operating frequency band. Compared with the first operating frequency band generated by the first antenna unit 111 including the first frequency point, the resonance point is far away from the first operating frequency band, thereby reducing the influence of the metal decorative part 112 on the first antenna unit 111.

[0069] When the antenna assembly 11 also includes other antenna assemblies, in an optional embodiment, the antenna assembly 11 also includes a second antenna unit, the radiator of the second antenna unit is a metal decorative part 112, wherein the tuning circuit 111 is connected to a point other than a feeding point of the metal decorative part 112.

[0070] It can be understood that the antenna component 11 can also include an antenna unit with the metal decorative part 112 as a radiator, that is, a second antenna unit. It should be noted that when the antenna component 11 includes the above-mentioned second antenna unit, the tuning circuit 113 is connected to a point other than the feeding point of the metal decorative part 112. In this way, under the action of the tuning circuit 113, at least the above-mentioned three technical solutions are included, and the antenna performance of the second antenna unit is not affected.

[0071] The electronic device in one or more of the above embodiments is described below with examples.

[0072] Figure 4 A schematic diagram of the structure of an optional electronic device according to an embodiment of the present application is shown in FIG. Figure 4 As shown, antenna 1 is an antenna distributed on the frame of the mobile terminal, and antenna 2 is an antenna designed using a metal decorative part as a radiator. The two antennas operate at different operating frequencies. The two antennas are closely spaced, and the metal decorative parts are generally large, so mutual influence between the two often exists. Both antennas can add tuning switches to increase the operating frequency band and bandwidth.

[0073] Based on the operating frequency band of antenna 1, select Figure 4 The location where the tuning circuit is added in the middle; based on the operating frequency of antenna 2, select Figure 4The position of the middle feed 2 can be achieved by adding matching at the position of the feed 2 to adjust the standing wave of the antenna 2, and adding a tuning circuit at the position where the tuning circuit is added to adjust the influence of the metal decoration on the antenna 1, and the two do not affect each other.

[0074] Figure 5 A schematic diagram of an example of an optional tuning circuit provided in an embodiment of the present application is shown in FIG. Figure 5 As shown, it includes a first inductor (L1), a second inductor (L2), a first capacitor (C1) and a single-pole single-throw switch (SPST). The SPST is switched to change whether the metal decorative part is a parasitic load or a grounded metal for the antenna 1, thereby changing the working efficiency and directivity coefficient of the antenna 1. As for the state of the SPST in the tuning circuit, different SPST states can be switched by software control under different usage scenarios of the mobile terminal.

[0075] In this example, antenna 1 works at Wireless Fidelity (Wi-Fi) 2.4G, and antenna 2 works at 900MHz. No switch is added to the feed end of antenna 1 and antenna 2, but SPST is added to the tuning circuit of the metal decorative part. The fixed matching of feed 1 and feed 2 is adjusted to make the two antennas work at their respective target frequencies. SPST corresponds to different situations (CASE) in different states:

[0076] CASE1: SPST is in the off state, adjust Figure 5 The inductance value of L1 makes the metal decoration resonate at Wi-Fi 2.4G, thus achieving a parasitic loading effect for antenna 1; Figure 6 An example of an optional S parameter provided in the embodiment of the present application Figure 1 ,like Figure 6 As shown, the horizontal axis is frequency and the vertical axis is S parameter. Under CASE1, the S parameters of antenna 1 and antenna 2 are shown in Figure 6 , Figure 6 The resonance of 2.46 GHz is generated by antenna 1, while the resonance of 2.41 GHz is generated by the parasitic loading of the metal decorative parts. It can be seen that in CASE 1, the bandwidth of antenna 1 is improved.

[0077] Figure 7 An example of an optional antenna efficiency provided in an embodiment of the present application Figure 1 ,like Figure 7 As shown, the horizontal axis is the frequency, and the vertical axis is the total system efficiency. Under CASE1, it can be concluded from the total system efficiency curve of antenna 1 that the antenna efficiency of antenna 1 is -2.95dB; Figure 8An example of an optional antenna directivity coefficient provided in an embodiment of the present application Figure 1 ,like Figure 8 As shown, in CASE 1, the antenna directivity (Direction, Dir) coefficient of antenna 1 is 3.96.

[0078] CASE2: SPST is in the closed (on) state, adjusting Figure 5 The inductance value of L2 and the capacitance value of C1 make the resonance point of the metal decoration far away from Wi-Fi 2.4G, and the metal decoration is equivalent to high impedance for antenna 1; Fig. 9 An example of an optional S parameter provided in the embodiment of the present application Figure 2 ,like Fig. 9 As shown, the horizontal axis is frequency and the vertical axis is S parameter. Under CASE2, the S parameters of antenna 1 and antenna 2 are shown in Fig. 9 , Fig. 9 The resonance of 2.46 GHz is generated by antenna 1, while the resonance of 2.8 GHz is the resonance position of the metal decorative part, which is far away from the operating frequency of antenna 1, and the influence on antenna 1 is reduced.

[0079] Fig.10 An example of an optional antenna efficiency provided in an embodiment of the present application Figure 2 ,like Fig.10 As shown, the horizontal axis is frequency, and the vertical axis is the total system efficiency. Under CASE 2, the efficiency curve of antenna 1 can be obtained, and the antenna efficiency is -3.58dB.

[0080] Fig.11 An example of an optional antenna directivity coefficient provided in an embodiment of the present application Figure 2 ,like Fig.11 As shown, in case 2, the antenna directivity coefficient of antenna 1 is 3.45.

[0081] In this example, for antenna 12, antenna 2 has two matching circuits with or without a tuning circuit. The performance of antenna 1 under Wi-Fi 2.4G is compared. Figure 7 and Fig.10 As shown, it can be seen that in this example, a group of antennas 2 is added as follows Figure 5 When the tuning circuit is used as shown, it can also tune the antenna 1, so that the antenna efficiency of the antenna 1 is improved by 0.7-2dB.

[0082] It can be seen that the comparison Figure 6 and Fig. 9The S parameters of antenna 2 are basically the same, so the switching of SPST does not affect the operation of antenna 2. The antenna efficiency of antenna 1 in CASE1 is improved by 0.6dB compared with that in CASE2, while the directivity coefficient of antenna 1 in CASE2 is reduced by 0.5 compared with that in CASE1.

[0083] It should be noted that the antenna 2 may not be provided on the metal decorative part. Fig.12 A schematic diagram of a second example of an optional electronic device provided in an embodiment of the present application, such as Fig.12 As shown, only the tuning circuit is added to the metal decorative part. Antenna 1 can also be added with an antenna switch to work in different frequency bands. The switch form added to the tuning circuit on the metal decorative part can also be changed as needed, such as SPST / SP4T.

[0084] In this example, the metal decorative parts and the antenna are reused to reduce the directivity coefficient of the antenna 1. The use scenario can also be combined for determination to achieve the effect of automatically switching the antenna 1 to different antenna efficiencies and directivity coefficients.

[0085] That is to say, this example reduces the directivity coefficient of antenna 1 without adding new structural requirements; the switchable antenna performance can be switched between high total radiated power (Total radiated Power, TRP) and low equivalent isotropically radiated power (EIRP) as needed to adapt to different usage scenarios; the metal decorative part (or antenna 2) structure is reused to eliminate the adverse effects that it may have on surrounding antennas, and save layout space and matching costs.

[0086] An embodiment of the present application provides an electronic device, including: an antenna assembly, the antenna assembly including: a first antenna unit, a metal decorative part and a tuning circuit, one end of the tuning circuit is connected to the metal decorative part, the first antenna unit is used to generate a resonance point of a first frequency point, and the metal decorative part is used to generate a resonance point of a second frequency point, wherein the first frequency point is located within a first working frequency band of the antenna assembly, the second frequency point is located within the first working frequency band or the second frequency point is located outside the first working frequency band; that is, in the embodiment of the present application, when the metal decorative part affects the first antenna unit, the tuning circuit is connected to the metal decorative part. Then, under the action of the tuning circuit, the first antenna unit generates a resonance point of a first frequency, and the metal decorative part generates a resonance point of a second frequency. The first frequency belongs to a point within the first working frequency band of the antenna assembly, and the second frequency can be a point within the first working frequency band or a point outside the first working frequency band. In this way, after adding the tuning circuit, the resonance point of the metal decorative part is either located within the first working frequency band, which expands the bandwidth of the first working frequency band, or is located outside the first working frequency band, which reduces the impact on the first antenna unit. In this way, the antenna performance of the first antenna unit is guaranteed while improving the impact of the metal decorative part.

[0087] Based on the same inventive concept as the aforementioned embodiment, an embodiment of the present application provides a control method, which is applied to an electronic device, wherein the electronic device comprises: an antenna assembly, the antenna assembly comprises: a first antenna unit, a metal decorative part and a tuning circuit; wherein one end of the tuning circuit is connected to the metal decorative part; wherein the first antenna unit is used to generate a resonance point of a first frequency point; the metal decorative part is used to generate a resonance point of a second frequency point; wherein the first frequency point is located within a first working frequency band of the antenna assembly; when the tuning circuit is a third tuning circuit, the third tuning circuit comprises: a first inductor, a second inductor, a first capacitor and a switch; wherein one end of the first inductor is connected to the metal decorative part with the fixed end of the switch, the other end of the first inductor is grounded, one end of the second inductor is connected to one end of the first capacitor with the moving end of the switch, and the other end of the second inductor is grounded with the other end of the first capacitor; wherein when the switch is in an open state, the second frequency point is located within the first working frequency band; when the switch is in a closed state, the second frequency point is located outside the first working frequency band, Fig.13 A flow chart of an optional control method provided in an embodiment of the present application is as follows: Fig.13 As shown, the control method may include:

[0088] S1301: Obtaining a usage scenario of the electronic device;

[0089] S1302: According to a usage scenario of the electronic device, control the switch so that the second frequency point is located within the first working frequency band or the second frequency point is located outside the first working frequency band.

[0090] Among them, the above-mentioned usage scenario can be one of the preset scenarios of the electronic device, which may include: a call scenario of the electronic device, a video playback scenario of the electronic device, a game scenario of the electronic device, a video chat scenario of the electronic device, etc. The electronic device can first obtain the usage scenario, and then control the switch based on the acquired usage scenario, so that the second frequency point is either located within the first working frequency band or outside the first working frequency band.

[0091] From the above description, it can be seen that when the second frequency point is within the first working frequency band, the antenna efficiency of the first antenna unit is improved. When the second frequency point is outside the first working frequency band, the antenna directivity coefficient of the first antenna unit is reduced. Based on this, the state of the switch can be controlled according to the requirements of the antenna efficiency and antenna directivity coefficient in the usage scenario.

[0092] For different usage scenarios, in an optional embodiment, S1302 may include:

[0093] When the usage scenario is the preset first type of scenario, the control switch is in an off state so that the second frequency point is located within the first working frequency band;

[0094] When the usage scenario is the preset second type of scenario, the control switch is in a closed state so that the second frequency point is located outside the first working frequency band.

[0095] It can be understood that the usage scenarios of electronic devices can be divided into two categories, namely first usage scenarios and second usage scenarios, wherein the first scenario is a scenario where the required antenna efficiency is greater than a preset efficiency threshold, that is, for usage scenarios with higher antenna efficiency requirements, the control switch is in the off state, so that the second frequency band is within the first working frequency band. At this time, the antenna efficiency of the first antenna unit is relatively high and can meet the requirements of the usage scenario at this time.

[0096] Among them, the second type of scenario is a scenario where the required antenna directivity coefficient is less than a preset coefficient threshold. That is to say, for usage scenarios with higher requirements for the antenna directivity coefficient, the control switch is in a closed state, so that the second frequency band is outside the first operating frequency band. At this time, the antenna directivity coefficient of the first antenna unit is low, which can meet the requirements of the usage scenario at this time.

[0097] The control method described in one or more of the above embodiments is described below with examples.

[0098] For mobile terminals, antenna efficiency and directivity are important performance parameters. When the directivity is low, there are fewer communication dead spots between the terminal and the base station. Currently, regulations in some regions have maximum limits on EIRP. The relationship between EIRP, directivity D, antenna efficiency η, and conducted power P is as follows:

[0099] EIRP=P+D+η (1)

[0100] The TRP performance of the whole machine is calculated by the following formula:

[0101] TRP=P+η (2)

[0102] It can be seen from formulas (1) and (2) that for mobile terminals with fixed conduction values, the TRP and EIRP of Case 1 are both high, while the EIRP and TRP of Case 2 are both relatively low.

[0103] based on Figure 4 and Figure 5 electronic devices, Fig.14 A schematic diagram of an example of an optional control method provided in an embodiment of the present application is shown in FIG. Fig.14 As shown, the control method may include:

[0104] S1401: The mobile terminal performs scene recognition;

[0105] S1402: The mobile terminal determines that the scenario is a scenario requiring high antenna efficiency, and executes S1404;

[0106] The above-mentioned scenario requiring high antenna efficiency may be a scenario requiring the antenna efficiency to be greater than a preset efficiency threshold.

[0107] S1403: The mobile terminal determines that the scenario requires a low antenna directivity coefficient, and executes S1405;

[0108] The scenario requiring a low antenna directivity coefficient may be a scenario requiring the antenna directivity coefficient to be less than a preset coefficient threshold.

[0109] S1404: Control SPST OFF and enter CASE1 state.

[0110] S1405: Control SPST ON and enter CASE2 state.

[0111] It can be seen that the performance requirements can be classified according to the usage scenarios of mobile terminals, so that different CASE states can be used in different scenarios.

[0112] It should be noted that the operating frequency band of antenna 1 is not limited to Wi-Fi 2.4G, but can also be Wi-Fi 5G or any other frequency band; antenna 2 may not be made on the metal decorative part, and only a tuning circuit may be added to change the performance of antenna 1; the antenna switch may not be added to the tuning circuit, so it can only work in one of the situations of improving antenna efficiency (CASE1) or lowering antenna directivity coefficient (CASE2); other switches with more switching states such as SP4T may also be added to adjust more operating frequency bands, which can be determined based on antenna 1.

[0113] In summary, this example reuses the metal decorative part structure. Without affecting the antenna on the decorative part, by adding a tuning circuit, the metal decorative part is in different working states for the target antenna, and these states are switched by adding an antenna switch. Combined with the scene recognition of the mobile terminal, the software configures the logic, so as to achieve the effect of automatically switching the antenna performance (antenna efficiency, directivity coefficient) according to the scene.
