[0028] The following will be combined with the attached examples of the present application Figure 1 To Attachment Fig.11 , the technical solutions in the embodiments of the present application are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0029] The embodiment of the present application provides an electronic device, which may be a smart phone, a tablet computer or other device, or a gaming device, an augmented reality (AR) device, an automotive device, a data storage device, an audio playback device, a video playback device, a laptop computer, a desktop computing device, etc. The electronic device has a wireless communication function. For example, the electronic device can transmit wireless fidelity (Wi-Fi) signals, global positioning system (GPS) signals, third-generation mobile communication technology (3rd-Generation, 3G), fourth-generation mobile communication technology (4th-Generation, 4G), fifth-generation mobile communication technology (5th-Generation, 5G), near field communication (NFC) signals, Bluetooth (BT) signals, ultra-wideband communication (UWB) signals, etc.

[0030] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of a first structure of an electronic device 10 provided in an embodiment of the present application. Figure 2 for Figure 1 The electronic device 10 is shown in another state. Figure 3 for Figure 1 The electronic device 10 includes a first body 100 , a second body 200 , a first antenna 301 and a second antenna 302 .

[0031] The first body 100 and the second body 200 can be folded or slid toward each other so that the electronic device 10 can be in an unfolded state or an overlapping state. Figure 1 As shown, the electronic device 10 may be in an unfolded state where the first body 100 and the second body 200 are away from each other; Figure 2 As shown, the electronic device 10 may be in an overlapping state where at least a portion of the second body 200 and the first body 100 overlap each other. Figures 1 to 3As shown, the first antenna 301 is disposed on the first body 100, and the first antenna 301 includes a first radiator 310 and a first feed source 320. The first feed source 320 can be electrically connected to the first radiator 310 to feed a first excitation signal to the first radiator 310. The second antenna 302 is disposed on the second body 200, and the second antenna 302 includes a second radiator 330, a second feed source 340 and an adjustment module 350. The second feed source 340 can be electrically connected to the second radiator 330 to feed a second excitation signal to the second radiator 330, and the adjustment module 350 can be electrically connected to the second radiator 330 to adjust the radiation resonance mode of the second radiator 330. Figure 1 As shown, in the unfolded state, the first radiator 310 and the second radiator 330 are away from each other, the first feed source 320 can stimulate the first radiator 310 to support a first wireless signal, and the second feed source 340 can stimulate the second radiator 330 to support a second wireless signal, which is different from the first wireless signal. Figure 2 As shown, in the overlapping state, at least a portion of the second radiator 330 may overlap with the first radiator 310, the first feed source 320 may excite the first radiator 310 to work so that the first antenna 301 supports the first wireless signal, and the second radiator 330, under the excitation of the first feed source 320, is electromagnetically coupled with the first radiator 310 and supports the third wireless signal. At this time, under the action of the adjustment module 350, the third wireless signal is different from the first wireless signal.

[0032] It is understandable that the first body 100 and the second body 200 may be thin plate or sheet structures, or may be hollow frame structures. The first body 100 and the second body 200 may provide support for the electronic devices in the electronic device 10 so as to install the electronic devices in the electronic device 10 together. For example, electronic devices such as a camera, a receiver, a circuit board with a radio frequency circuit such as a feed source, and a power supply in the electronic device 10 may be installed on the first body 100 and the second body 200 for fixing.

[0033] It is understood that during the folding or sliding operation, the first body 100 and the second body 200 can switch between the overlapping state and the unfolded state. Figure 1 As shown, the first body 100 and the second body 200 can be moved away from each other to the unfolded state. At this time, the distance between the first antenna 301 set in the first body 100 and the second antenna 302 set in the second body 200 is relatively far, and the first antenna 301 and the second antenna 302 are not easy to interfere with each other when working independently. The antenna performance when the first antenna 301 supports the first wireless signal and the second antenna 302 supports the second wireless signal is relatively good. Figure 2As shown, the first body 100 and the second body 200 can also be close to each other to an overlapping state. At this time, the distance between the first antenna 301 and the second antenna 302 is relatively close, and at least part of the second radiator 330 can overlap with the first radiator 310. The first radiator 310 of the first antenna 301 and the second radiator 330 of the second antenna 302 are likely to generate an electromagnetic coupling connection, the first antenna 301 and the second antenna 302 are likely to interfere with each other, and the first antenna 301 is easily affected by the overlapping state, resulting in a decrease in antenna performance.

[0034] In order to reduce the impact of the overlapping state on the performance of the first antenna 301, the adjustment module 350 of the second antenna 302 of the embodiment of the present application can adjust the electrical length of the second radiator 330 to adjust the resonant mode of the second radiator 330, so that the third wireless signal supported by the second radiator 330 after electromagnetic coupling with the first radiator 310 is different from the first wireless signal supported by the first antenna 301, so that the third wireless signal is not easy to affect the first wireless signal, and the first wireless signal can still have good radiation performance in the overlapping state. Among them, the electrical length refers to the equivalent length of the radiator when radiating a signal, or refers to the equivalent length required for electromagnetic wave transmission in the radiation structure. The electrical length of the radiator can be greater than, less than or equal to its branch length. The adjustment module 350 may include an indefinite number of capacitors and inductors so that the second radiator 330 changes its electrical length by electrically connecting circuits with different impedances, so that the third wireless signal is different from the first wireless signal.

[0035] It can be understood that the frequency range of the third wireless signal may be completely separated from the frequency range of the first wireless signal in the frequency spectrum, or the frequency range of the third wireless signal may partially overlap with the frequency range of the first wireless signal and the center frequencies of the two are different, so that the third wireless signal is different from the first wireless signal. For example, the first wireless signal may be a wireless signal in the B3 frequency band (1710MHz-1880MHz), the center frequency of the third wireless signal may be 2000MHz, and the frequency range of the third wireless signal is separated from that of the first wireless signal. Similarly, the frequency range of the second wireless signal may be completely separated from the frequency range of the first wireless signal or the two may partially overlap and the center frequencies are different, so that the second wireless signal is different from the first wireless signal. For example, the first wireless signal may be a wireless signal in the medium and high frequency band (1000MHz to 3000MHz), and the second wireless signal may be a wireless signal in the low frequency band (less than 1000MHz).

[0036] It can be understood that in order to further improve the antenna performance of the first wireless signal, the difference between the center frequency of the third wireless signal supported by the second radiator 330 and the center frequency of the first wireless signal in the overlapping state can be about 10% to 15% of the center frequency of the first wireless signal, so that the third wireless signal supported by the second radiator 330 can further improve the antenna efficiency of the first wireless signal. For example, when the first wireless signal is in the B3 frequency band, the center frequency of the third wireless signal can be 2000MHz, at which time the antenna efficiency of the first wireless signal can be improved by 0.5dB compared to the antenna efficiency of the first wireless signal in the unfolded state, and the antenna performance of the first wireless signal is better.

[0037] It can be understood that the first radiator 310 can support the first wireless signal in a quarter-wavelength mode, but is not limited to it. The first radiator 310 may include a first free end 311 and a first ground end 312 and a first feeding point 313 arranged between the first free end 311 and the first ground end 312. The first feed source 320 is electrically connected to the first feeding point 313, and the first ground end 312 is electrically connected to the ground system 360 to achieve grounding. The first feed source 320 can excite the first radiator 310 to generate a resonant current flowing from the first ground end 312 to the first free end 311 so that the first radiator 310 supports the first wireless signal. Of course, the first radiator 310 can also support the first wireless signal in other resonant modes, which is not limited in the embodiment of the present application. Among them, the ground system 360 can be a plane or structure with a zero potential, and the ground system 360 can form a common ground. The ground system 360 can be formed by a conductor, a printed circuit, or a metal printing layer in the electronic device 10.

[0038] It can be understood that the second radiator 330 may include a first end 331 and a second end 332, and a second feeding point 333 disposed between the first end 331 and the second end 332, the second feed source 340 may be electrically connected to the second feeding point 333, the second radiator 330 may also be electrically connected to the ground system 360, and the second radiator 330 may, but is not limited to, support the second wireless signal in a quarter-wavelength mode. Of course, the second radiator 330 may also support the second wireless signal in other modes, which is not limited in the embodiment of the present application.

[0039] It is understandable that if Figure 1 and Figure 2 As shown, the electronic device 10 may also include, but is not limited to, a connection structure 400 such as a rotating shaft structure and a sliding rail structure, so that the first body 100 and the second body 200 can be folded and slid relative to each other. The specific structure of the connection structure 400 such as the rotating shaft structure and the sliding rail structure can be referred to the description in the related art, and will not be described in detail here.

[0040] In the electronic device 10 of the embodiment of the present application, when the electronic device 10 is in the unfolded state, the first antenna 301 can support the transmission and reception of the first wireless signal, and the second antenna 302 can support the transmission and reception of the second wireless signal, so that the electronic device 10 can support multiple wireless signals, and the application scenarios of the electronic device 10 are wider; when the electronic device 10 is in the overlapping state, the first antenna 301 can still support the transmission and reception of the first wireless signal. At this time, under the action of the adjustment module 350, the second radiator 330 can be electromagnetically coupled with the first radiator 310 under the excitation of the first feed source 320 and support a third wireless signal different from the first wireless signal. The second radiator 330 is not easy to affect the performance of the first antenna 301 in supporting the first wireless signal, so that the first antenna 301 can also have better antenna performance in the overlapping state.

[0041] Among them, when the electronic device 10 is in an overlapping state, the adjustment module 350 can also enable the second radiator 330 to be electromagnetically coupled with the first radiator 310 under the excitation of the second feed source 340 and support a third wireless signal of a different frequency band; at this time, according to the first wireless signal supported by the first radiator 310, a third wireless signal that is far away from the frequency band range of the first wireless signal (for example, the difference between the center frequency of the third wireless signal and the center frequency of the first wireless signal can be about 10% to 15% of the center frequency of the first wireless signal) and has a better antenna efficiency within the frequency range of the first wireless signal can be selected from the multiple third wireless signals supported by the second radiator 330. The third wireless signal has a better antenna efficiency within the frequency range of the first wireless signal. The electronic device 10 can control the operation of the adjustment module 350 according to the state of the adjustment module 350 corresponding to the third wireless signal, so that the third wireless signal supported by the second radiator 330 can not only not interfere with the first wireless signal, but also improve the antenna performance of the first wireless signal.

[0042] When the electronic device 10 is in the unfolded state, the adjustment module 350 can also enable the second feed source 340 to stimulate the second radiator 330 to support second wireless signals of different frequency bands. Thus, in the unfolded state, the second radiator 330 can support second wireless signals of more frequency bands, for example, the second radiator 330 can cover more low-frequency bands.

[0043] It should be noted that the adjustment module 350 can enable the second radiator 330 to support a third wireless signal of a different frequency band in the overlapping state; or, the adjustment module 350 can enable the second feed source 340 to stimulate the second radiator 330 to support a second wireless signal of a different frequency band in the unfolded state; or, 350 can enable the second radiator 330 to support a third wireless signal of a different frequency band in the overlapping state, and can enable the second feed source 340 to stimulate the second radiator 330 to support a second wireless signal of a different frequency band in the unfolded state. The embodiment of the present application does not limit the role of the adjustment module 350.

[0044] Among them, please refer to Figure 4 and Figure 5 , Figure 4 A second structural diagram of the electronic device 10 provided in an embodiment of the present application is shown in FIG. Figure 5 for Figure 4 An electrical connection diagram of the electronic device 10 is shown. The adjustment module 350 may include a first switching circuit 351 .

[0045] The first switching circuit 351 includes a first switch 3511 and a first switching branch 3512. The first switch 3511 includes a first common end a1 and a first switching end b1. The first common end a1 is electrically connected to the second radiator 330. One end of the first switching branch 3512 is electrically connected to the first switching end b1, and the other end of the first switching branch 3512 is electrically connected to the second feed source 340.

[0046] It can be understood that, in the unfolded state, the first feed source 320 can excite the first radiator 310 to support the first wireless signal, and at this time, the first switch 3511 can conduct the first common terminal a1 and the first switching terminal b1, so that the second feed source 340 excites the second radiator 330 to support the second wireless signal. Thus, in the unfolded state, the first antenna 301 and the second antenna 302 can work simultaneously and make the first antenna 301 support the first wireless signal and the second antenna 302 support the second wireless signal.

[0047] It can be understood that, in the overlapping state, the first feed source 320 can still excite the first radiator 310 to support the first wireless signal. At this time, the first switch 3511 can disconnect the connection between the first common end a1 and the first switching end b1, so that the second radiator 330 is electromagnetically coupled with the first radiator 310 under the excitation of the first feed source 320 and supports the third wireless signal.

[0048] It can be understood that the first switching branch 3512 can be but is not limited to an indefinite number of capacitor elements or inductor elements, and the first switching branch 3512 can also serve as a matching structure to perform impedance matching adjustment on the second excitation signal provided by the second feed source 340, so as to further improve the radiation performance of the second wireless signal supported by the second radiator 330 excited by the second feed source 340.

[0049] The adjustment module 350 of the embodiment of the present application includes a first switching circuit 351. Under the action of the first switching circuit 351, the first feed source 320 can be connected to the second radiator 330 so that the second antenna 302 supports the second wireless signal in the unfolded state. The first feed source 320 can also be disconnected from the second radiator 330 so that the second radiator 330 supports the third wireless signal in the unfolded state.

[0050] Among them, please refer to Figure 6 and Figure 7 , Figure 6 This is a third structural diagram of the electronic device 10 provided in the embodiment of the present application. Figure 7 for Figure 6 An electrical connection diagram of the electronic device 10 is shown. The adjustment module 350 may further include a second switching circuit 352 .

[0051] One end of the second switching circuit 352 is electrically connected to the second radiator 330, and the other end of the second switching circuit 352 is grounded. The second switching circuit 352 includes a second switch 3521 and a plurality of (a plurality of two or more) second switching branches 3522. The second switch 3521 includes a second common terminal a2 and a plurality of second switching terminals. The second common terminal a2 is electrically connected to the second radiator 330, one end of each second switching branch 3522 is electrically connected to a second switching terminal, and the other end of each second switching branch 3522 is grounded. For example, the second switching circuit 352 includes a second switching branch 3522a, a second switching branch 3522b, a second switching branch 3522c, and a second switching branch 3522d; the second switch 3521 includes a second switching terminal b21, a second switching terminal b22, a second switching terminal b23, and a second switching terminal b24. Among them, one end of the second switching branch 3522a is electrically connected to the second switching end b21, and the other end is grounded; one end of the second switching branch 3522b is electrically connected to the second switching end b22, and the other end is grounded; one end of the second switching branch 3522c is electrically connected to the second switching end b23, and the other end is grounded; one end of the second switching branch 3522d is electrically connected to the second switching end b24, and the other end is grounded.

[0052] It can be understood that, in the overlapping state, the first switch 3511 is used to disconnect the first common terminal a1 and the first switching terminal b1, and the second switch 3521 is used to switch between turning on the second common terminal a2 and multiple second switching terminals, so that the second radiator 330 is electromagnetically coupled with the first radiator 310 under the excitation of the first feed source 320 and supports a third wireless signal of a different frequency band.

[0053] It can be understood that, in the expanded state, the first switch 3511 is used to conduct the connection between the first common terminal a1 and the first switching terminal b1, and the second switch 3521 is used to switch between conducting the electrical connection between the second common terminal a2 and multiple second switching terminals, so that the second feed source 340 excites the second radiator 330 to support the second wireless signal of a different frequency band.

[0054] It is understandable that each second switching branch 3522 may include an indefinite number of capacitors, inductors and other components, and the impedances of at least two second switching branches 3522 are different, so that at least two second switching branches 3522 can make the second radiator 330 have different electrical lengths. Figure 7As shown, the second switching circuit 352 includes four second switching branches 3522, wherein two of the second switching branches 3522, such as the second switching branch 3522b and the second switching branch 3522c, include inductive load elements, wherein another second switching branch 3522, such as the second switching branch 3522a, includes a capacitive load element, and wherein another second switching branch 3522, such as the second switching branch 3522d, is directly grounded.

[0055] It can be understood that a second switching branch 3522b of the second switching circuit 352 includes a first inductor, one end of which is electrically connected to a second switching terminal b22 and the other end is grounded; another second switching branch 3522c includes a second inductor, one end of which is electrically connected to a second switching terminal b23 and the other end is grounded; another second switching branch 3522a includes a first capacitor, one end of which is electrically connected to a second switching terminal b21 and the other end is grounded; and one end of the last second switching branch 3522d is electrically connected to a second switching terminal b24 and the other end is directly grounded. The inductance value of the second inductor may be different from the inductance value of the first inductor, so that when the second common terminal a2 of the second switch 3521 is turned on with different second switching terminals, the second radiator 330 can support second wireless signals of different frequency bands.

[0056] For example, when the second switch 3521 conducts the second common terminal a2 and the second switching terminal b21 so that the first capacitive element is grounded, the second radiator 330 can support a second wireless signal in a frequency band such as but not limited to the B8 frequency band (880MHz-960MHz) or the N8 frequency band (880MHz-960MHz). When the second switch 3521 conducts the second common terminal a2 and the second switching terminal b24 so that the second switching branch 3522d is directly grounded, the second radiator 330 can support a second wireless signal in a frequency band such as but not limited to the B5 frequency band (824MHz-894MHz) or the N5 frequency band (824MHz-894MHz). When the second switch 3521 conducts the second common terminal a2 and the second switching terminal b22 so that the first inductive element is directly grounded, the second radiator 330 can support a second wireless signal in a frequency band such as but not limited to the b10 frequency band (791MHz-862MHz) or the N20 frequency band (791MHz-862MHz). When the second switch 3521 conducts the second common terminal a2 and the second switching terminal b23 so that the second inductor element is directly grounded, the second radiator 330 can support a second wireless signal in a frequency band such as but not limited to the b18 frequency band (703MHz to 803MHz) or the N28 frequency band (703MHz to 803MHz). When the second switch 3521 conducts the second common terminal a2 and all the second switching terminals, the second radiator 330 can support a second wireless signal in a frequency band such as but not limited to the B71 frequency band (617MHz-698MHz) or the N71 frequency band (617MHz-698MHz).

[0057] It can be understood that the frequency band range covered by the second wireless signal may include the B71 band, the B28 band, the B20 band, the B5 band, the B8 band, the N71 band, the N28 band, the N20 band, the N5 band or the N8 band. Thus, under the action of the second switching circuit 352, the second antenna 302 can support the second wireless signal of the B71 band, the b18 band, the b10 band, the B5 band, the B8 band, the N71 band, the N28 band, the N20 band, the N5 band or the N8 band in the unfolded state, and the second antenna 302 can support the second wireless signal of multiple low-frequency bands in the unfolded state, and the second antenna 302 can cover more low-frequency bands. Of course, under the action of the second switching circuit 352, the second antenna 302 can also support the second wireless signal of other frequency bands such as but not limited to medium-high frequency bands, high frequency bands, etc. in the unfolded state. The embodiment of the present application does not limit the frequency band of the second wireless signal supported by the second antenna 302.

[0058] It should be noted that the above is only an exemplary description of the operation of the second switching circuit 352. The second switching circuit 352 can also realize the switching of second wireless signals of different frequency bands and the switching of third wireless signals of different frequency bands through other switching methods; of course, the second switching circuit 352 can also have other structures, such as but not limited to including more second switching branches 3522. The embodiment of the present application does not limit the specific structure and specific working method of the second switching circuit 352.

[0059] It can be understood that the second switch 3521 can be a multi-pole multi-throw switch, or the second switch 3521 can be a switch network. The second switch 3521 can conduct one second switching branch 3522 to ground, or the second switch 3521 can conduct multiple second switching branches 3522 to ground. The embodiment of the present application does not limit the specific structure of the second switch 3521.

[0060] The adjustment module 350 of the embodiment of the present application includes a second switching circuit 352. Under the switching of the second switching circuit 352, the second antenna 302 can support second wireless signals of more frequency bands, and the second antenna 302 can also support third wireless signals of more frequency bands, so that the second antenna 302 can be applied to more communication scenarios, and the application scenarios of the electronic device 10 are also wider.

[0061] Among them, Figure 7 As shown, the first switching circuit 351 may further include a fourth switching branch 3514 and at least one third switching branch 3513; the first switch 3511 may further include at least one third switching terminal, such as a third switching terminal b31, a third switching terminal b32 and a third switching terminal b33.

[0062] One end of each third switching branch 3513 is electrically connected to a third switching terminal, and the other end of each third switching branch 3513 is grounded. One end of the fourth switching branch 3514 is electrically connected between the first common terminal a1 and the second radiator 330, and the other end of the fourth switching branch 3514 is grounded.

[0063] It can be understood that, in the unfolded state, the first switch 3511 can conduct the first common terminal a1 and the first switching terminal b1, and the second switch 3521 is used to switch between conducting the second common terminal a2 and multiple second switching terminals, so that the second feed source 340 excites the second radiator 330 to support the second wireless signal of different frequency bands.

[0064] It can be understood that, in the overlapping state, the first switch 3511 can disconnect the connection between the first common terminal a1 and the first switching terminal b1, the second switch 3521 can turn on or off the second common terminal a2 and at least one second switching terminal, and the first switch 3511 can also turn on or off the electrical connection between the first common terminal a1 and at least one third switching terminal, so that the second radiator 330 is electromagnetically coupled with the first radiator 310 under the excitation of the first feed source 320 and supports a third wireless signal different from the first wireless signal.

[0065] It is understandable that the first switching branch 3512, the third switching branch 3513 or the fourth switching branch 3514 of the first switching circuit 351 may include an indefinite number of capacitive elements and inductive elements. For example, the first switching branch 3512 may include an inductive load element or a capacitive load element, the fourth switching branch 3514 may include an inductive load element, and the third switching branch 3513 may include an inductive load element, a capacitive load element or other elements. Figure 7 As shown, the first switching circuit 351 includes three third switching branches 3513, such as a third switching branch 3513a, a third switching branch 3513b and a third switching branch 3513c, wherein one third switching branch 3513a includes an inductive load element, such as a third inductor element, one end of the third inductor element can be electrically connected to a third switching terminal b31, and the other end of the third inductor element can be grounded; wherein another third switching branch 3513b includes a capacitive load element, such as a second capacitor element, one end of the second capacitor element can be electrically connected to a third switching terminal b32, and the other end of the second capacitor element can be grounded; wherein another third switching branch 3513c is directly grounded.

[0066] The switching states of the first switching circuit 351 and the second switching circuit 352 can be controlled according to the frequency range of the first wireless signal supported by the first radiator 310, so that the second radiator 330 can support a third wireless signal of a suitable frequency band under the joint action of the first switching circuit 351 and the second switching circuit 352, so as to avoid interference of the third wireless signal to the first wireless signal and enable the first wireless signal to have a better antenna efficiency.

[0067] For example, please combine Figure 7 Please also refer to Figure 8 , Figure 8 Schematic diagram of S parameter curve when the electronic device 10 of the embodiment of the present application supports wireless signals of different frequency bands. In the overlapping state, when the first antenna 301 supports the B3 frequency band, under the switching action of the first switching circuit 351 and the second switching circuit 352, the second radiator 330 is electromagnetically coupled with the first radiator 310 under the excitation of the first feed source 320 and can support a third wireless signal of a different frequency band.

[0068] Wherein, curve S1 is an S parameter curve of a wireless signal of a certain frequency band supported by the first radiator 310 and the second radiator 330 under the excitation of the first feed source 320 when the second switch 3521 of the second switching circuit 352 disconnects the electrical connection between the second common terminal a2 and all the switching terminals and the first switch 3511 of the first switching circuit 351 disconnects the electrical connection between the first common terminal a1 and all the switching terminals in the overlapping state, Figure 8 It can be seen from the A1 area that the frequency of the wireless signal supported by the second radiator 330 is closer to the first wireless signal (B3 frequency band signal) supported by the first radiator 310, resulting in an efficiency pit in the frequency range of the first wireless signal, which can affect the antenna efficiency of the first wireless signal.

[0069] Among them, curve S2 is an S parameter curve of the first radiator 310 and the second radiator 330 supporting a wireless signal of another frequency band (for example, a third wireless signal of a certain frequency band) under the excitation of the first feed source 320 when the second switch 3521 of the second switching circuit 352 is grounded through at least one second switching branch 3522 in the overlapping state and the first switch 3511 of the first switching circuit 351 disconnects the electrical connection between the first common end a1 and all switching ends. It can be seen from the A2 area that at this time, the frequency range of the third wireless signal supported by the second radiator 330 does not fall within the frequency range of the first wireless signal supported by the first radiator 310, and the third wireless signal supported by the second radiator 330 is not likely to affect the first wireless signal.

[0070] Among them, curve S3 and curve S4 are S parameter curves of the first radiator 310 and the second radiator 330 supporting a wireless signal of another frequency band (for example, a third wireless signal of another frequency band) under the excitation of the first feed source 320 when the second switch 3521 of the second switching circuit 352 is grounded through at least one second switching branch 3522 in an overlapping state and the first common end a1 of the first switch 3511 of the first switching circuit 351 is respectively turned on to the third inductor element and the second capacitor element. It can be seen from the A3 area that at this time, the frequency range of the third wireless signal supported by the second radiator 330 does not fall within the frequency range of the first wireless signal supported by the first radiator 310, and the third wireless signal supported by the second radiator 330 is not likely to affect the first wireless signal.

[0071] Among them, curve S5 is an S parameter curve of the wireless signal supported by the first radiator 310 and the second radiator 330 under the excitation of the first feed source 320 when the second switch 3521 of the second switching circuit 352 is grounded through at least one second switching branch 3522 and the first switch 3511 of the first switching circuit 351 is grounded through the third switching branch 3513c in the overlapping state. It can be seen from the A4 area that at this time, the frequency range of the third wireless signal supported by the second radiator 330 does not fall within the frequency range of the first wireless signal supported by the first radiator 310, and the third wireless signal supported by the second radiator 330 is not easy to affect the first wireless signal.

[0072] according to Figure 8 The multiple curves shown can be used to analyze the efficiency of the first switching circuit 351 and the second switching circuit 352 of the second radiator 330 under different states according to the first wireless signal of the B3 frequency band supported by the first antenna 301; taking the frequency band range covered by the first wireless signal (for example, the B3 frequency band range) as a reference, the efficiency pit generated by the second radiator 330 under different switching circuits is far from the frequency band range of the first wireless signal, and the state of the first switching circuit 351 and the second switching circuit 352 corresponding to the curve with the highest efficiency within the frequency band range covered by the first wireless signal (for example, the B3 frequency band range) can be the optimal switching circuit state of the second radiator 330 by the adjustment module 350 under the current first wireless signal. For example, compare Figure 8 Regarding the frequency range from area A2 to area A4 and the antenna efficiency of each area in the frequency band range covered by the first wireless signal (for example, the B3 band), the switching states of the second switching circuit 352 and the first switching circuit 351 corresponding to area A3 can be selected to control the two switching circuits, so that at this time the third wireless signal supported by the second radiator 330 not only does not interfere with the first wireless signal, but the antenna efficiency of the third wireless signal within the frequency band range covered by the first wireless signal (for example, the B3 band) is higher; even in the switching states of the second switching circuit 352 and the first switching circuit 351 corresponding to area A3, the third wireless signal can also additionally enhance the antenna performance of the first wireless signal.

[0073] It can be understood that the first switch 3511 of the first switching circuit 351 can be a multi-pole multi-throw switch, or the first switch 3511 can be a switch network. The first switch 3511 can conduct one third switching branch 3513 to ground, or the first switch 3511 can conduct multiple third switching branches 3513 to ground. The embodiment of the present application does not limit the specific structure of the first switch 3511.

[0074] It can be understood that when the first wireless signal is in a different frequency range, the electronic device 10 can control the first switching circuit 351 and the second switching circuit 352 to select different switching states, so that the third wireless signal supported by the second radiator 330 under the action of the first switching circuit 351 and the second switching circuit 352 is different from the first wireless signal at this time.

[0075] It can be understood that the first wireless signal can be but is not limited to a medium or high frequency wireless signal. Under the action of the second switching circuit 352 and the first switching circuit 351, the third wireless signal supported by the second radiator 330 can cover a frequency band range of 1.5 GHz to 4 GHz. The third wireless signal can cover a wider frequency band range, so that when the first wireless signal is a different medium or high frequency wireless signal, the second switching circuit 352 and the first switching circuit 351 have corresponding switching states, so that the third wireless signal is different from the first wireless signal.

[0076] It can be understood that the first switching circuit 351 can be electrically connected to the second switching circuit 352 in different areas of the second radiator 330. For example, the second radiator 330 includes a first electrical connection point 334 and a second electrical connection point 335 arranged between the first end 331 and the second end 332. The first electrical connection point 334 can be arranged near the first end 331 (for example, the distance between the first electrical connection point 334 and the first end 331 can be less than or equal to one sixteenth of the length of the branch of the second radiator 330), and the second electrical connection point 335 can be arranged near the second end 332 (for example, the distance between the second electrical connection point 335 and the second end 332 can be less than or equal to one sixteenth of the length of the branch of the second radiator 330). The first common end a1 of the first switching circuit 351 can be electrically connected to the first electrical connection point 334, and the second common end a2 of the second switching circuit 352 can be electrically connected to the second electrical connection point 335. At this time, the second switching circuit 352 and the first switching circuit 351 can adjust the electrical length of the entire second radiator 330, and the second switching circuit 352 and the first switching circuit 351 can adjust a wider frequency band range.

[0077] It can be understood that since the first switching branch 3512 of the first switching circuit 351 is electrically connected to the second feed source 340, the first switching circuit 351 can also be electrically connected to the second feeding point 333 of the second radiator 330. At this time, the first electrical connection point 334 can overlap with the second feeding point 333, and the second feed source 340 can be electrically connected to the second radiator 330 through the first switching circuit 351.

[0078] It can be understood that the second switching circuit 352 and the first switching circuit 351 of the present application can be arbitrarily combined into a plurality of switching states (for example, the two switching circuits of the present application can be combined into up to more than 20 switching states), so that under the action of the second switching circuit 352 and the first switching circuit 351, the second radiator 330 can support a second wireless signal of a different frequency band under the action of the second feed source 340, and the second radiator 330 can also support a third wireless signal of a different frequency band different from the first wireless signal under the action of the first feed source 320.

[0079] It should be noted that the above is only an exemplary description of the second switching circuit 352 and the first switching circuit 351 of the embodiment of the present application. The second switching circuit 352 and the first switching circuit 351 may also be other structures, such as but not limited to more switching branches, and the embodiment of the present application does not limit the specific structure of the second switching circuit 352 and the first switching circuit 351. Similarly, the adjustment module 350 of the present application may also include other structures, such as but not limited to more or fewer switching circuits, and the embodiment of the present application does not limit the specific structure of the adjustment module 350.

[0080] In the electronic device 10 of the embodiment of the present application, when the first wireless signal supported by the first radiator 310 is a medium-high frequency signal and the second wireless signal supported by the second radiator 330 is a low frequency signal, the present application can realize a layout of a co-design of the medium-high frequency antenna and the opposite low frequency antenna; and, under the action of the second switching circuit 352 and the first switching circuit 351, the second radiator 330 can support low frequency signals of different frequency bands in the unfolded state, and the interference between the third wireless signal supported by the second radiator 330 and the first wireless signal supported by the first radiator 310 in the overlapping state is relatively small. Therefore, through the reasonable combination of the two switching circuits, the second radiator 330 can take into account both the low frequency antenna and the medium-high frequency antenna, and the antenna performance of the electronic device 10 is better.

[0081] Please refer again to Figure 6 and Figure 7 The electronic device 10 may further include a matching circuit 370, which may be electrically connected between the first feed source 320 and the first radiator 310. The matching circuit 370 may match and adjust the impedance of the excitation signal provided by the first feed source 320 to improve the antenna performance of the first radiator 310 in supporting the first wireless signal.

[0082] It is understandable that the matching circuit 370 may include, but is not limited to, an indefinite number of capacitor elements and inductor elements, and this embodiment of the present application does not limit this.

[0083] Among them, please refer to Fig. 9 , Fig. 9This is a third structural diagram of the electronic device 10 provided in the embodiment of the present application. The first body 100 may further include a first frame 110 , and the second body 200 may further include a second frame 210 .

[0084] The first frame 110 may be an outer frame of the first body 100, and the second frame 210 may be an outer frame of the second body 200. The first frame 110 and the second frame 210 may be made of a conductive material and have a certain rigidity. The first frame 110 and the second frame 210 may provide support for the electronic device or electronic components in the electronic device 10. Fig. 9 As shown, the first frame 110 can form a first metal branch 112 by opening a first slit 111, and the first radiator 310 can include the first metal branch 112; the second frame 210 can also form a second metal branch 212 by opening a second slit 211, and the second radiator 330 can include the second metal branch 212; thus, the first radiator 310 and the second radiator 330 can be metal frame radiators. In the overlapping state, at least part of the second metal branch 212 can overlap with the first metal branch 112, so that at least part of the second radiator 330 can overlap with the first radiator 310.

[0085] It is understandable that at least one of the first radiator 310 and the second radiator 330 may not be a metal frame radiator. For example, the first radiator 310 may be connected to the first frame 110 , and the second radiator 330 may be connected to the second frame 210 .

[0086] It can be understood that the first radiator 310 and the second radiator 330 can also be but are not limited to structures such as flexible circuit board radiators, printed circuit board radiators, laser direct forming radiators, and silver paste sprayed radiators. The embodiments of the present application do not limit the specific structures of the first radiator 310 and the second radiator 330.

[0087] It is understandable that the electronic device 10 may fill non-conductive material between the first gap 111 and the second gap 211 to increase the structural strength of the first frame 110 and the second frame 210 .

[0088] In the electronic device 10 of the embodiment of the present application, the first frame 110 and the second frame 210 are formed by slits to form the first radiator 310 and the second radiator 330. The first radiator 310 and the second radiator 330 do not need to occupy additional space of the electronic device 10, and the electronic device 10 can achieve a miniaturized design.

[0089] Please refer again to Fig. 9The first body 100 may further include a first middle plate 120, and the second body 200 may further include a second middle plate 220. The first middle plate 120 and the second middle plate 220 may be thin plates or thin sheet-like structures to provide support for electronic devices or functional components in the electronic device 10. The first frame 110 may be arranged around the edge of the first middle plate 120, and the second frame 210 may be arranged around the edge of the first middle plate 120.

[0090] It can be understood that at least one of the first middle plate 120 and the second middle plate 220 can be provided with a ground system 360, so that the first radiator 310 arranged on the first body 100 can be electrically connected to the ground system 360 on the first body 100 to achieve grounding, and the second radiator 330 arranged on the second body 200 can be electrically connected to the ground system 360 on the second body 200 to achieve grounding.

[0091] Please refer again Fig. 9 The electronic device 10 may further include a flexible display screen 500 , a circuit board 600 , and a power supply 700 .

[0092] The flexible display screen 500 can form a display surface of the electronic device 10 for displaying information such as images and texts. The flexible display screen 500 can include a display screen of a type such as a liquid crystal display (LCD) or an organic light-emitting diode (OLED) display screen. The flexible display screen 500 can be connected to the first body 100 and the second body 200, and can be folded along with the folding of the first body 100 and the second body 200.

[0093] For example, one end of the flexible display screen 500 may be connected to the first body 100, and the other end of the flexible display screen 500 may be connected to the second body 200. When the first body 100 and the second body 200 are in the unfolded state, the flexible display screen 500 may be arranged in the same plane as the first body 100 and the second body 200 are unfolded, and the flexible display screen 500 is in the unfolded state. When the first body 100 and the second body 200 are in the overlapping state, the flexible display screen 500 may be folded as the first body 100 and the second body 200 are folded, so that the two ends of the flexible display screen 500 may be close to each other or completely close to each other and folded together.

[0094] The circuit board 600 can be installed on the first body 100 or the second body 200, and the circuit board 600 can be the main board of the electronic device 10. A processor can be integrated on the circuit board 600, and one or more functional components such as an earphone interface, an acceleration sensor, a gyroscope, and a motor can also be integrated. Among them, the flexible display screen 500, the first feed source 320, the second feed source 340, the second switching circuit 352, the first switching circuit 351, and the matching circuit 370 can be set on the circuit board 600 to be controlled by the processor on the circuit board 600.

[0095] The power supply 700 may be mounted on the first body 100 or the second body 200. At the same time, the power supply 700 may be electrically connected to the circuit board 600 so that the power supply 700 supplies power to the electronic device 10. A power management circuit may be provided on the circuit board 600. The power management circuit is used to distribute the voltage provided by the power supply 700 to various electronic devices in the electronic device 10.

[0096] It can be understood that the above is only an illustrative example of the electronic device 10. The electronic device 10 of the embodiment of the present application may also include components such as a camera, a sensor, and an acoustic-to-electric conversion device. These components can be found in the description of the relevant technology and will not be repeated here.

[0097] Based on the structure of the above-mentioned electronic device 10, an embodiment of the present application also provides an antenna control method, which is applied to the electronic device 10 of any of the above-mentioned embodiments. The electronic device 10 includes a first body 100, a first antenna 301 arranged on the first body 100, a second body 200, and a second antenna 302 arranged on the second body 200. The first antenna 301 includes a first radiator 310 and a first feed source 320, and the second antenna 302 includes a second radiator 330, a second feed source 340 and an adjustment module 350. The second body 200 can move relative to the first body 100 so that the electronic device 10 is in an overlapping state in which at least part of the second body 200 overlaps with the first body 100, or in an unfolded state in which the first body 100 and the second body 200 are away from each other. In the overlapping state, at least part of the second radiator 330 can overlap with the first radiator 310. Among them, please refer to Fig.10 , Fig.10 A first flow chart of an antenna control method provided in an embodiment of the present application. The antenna control method includes:

[0098] In 101, when the electronic device 10 is in an unfolded state, the first feed source 320 is controlled to excite the first radiator 310 to support a first wireless signal, and the second feed source 340 is controlled to excite the second radiator 330 to support a second wireless signal, where the second wireless signal is different from the first wireless signal;

[0099] In the unfolded state, the first feed source 320 and the second feed source 340 can be controlled to operate. The first feed source 320 can feed a first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal. The second feed source 340 can feed a second excitation signal to the second radiator 330 to excite the second radiator 330 to support the second wireless signal.

[0100] It is understandable that the first wireless signal may be, but is not limited to, a medium-high frequency wireless signal, and the second wireless signal may be, but is not limited to, a low frequency wireless signal. Thus, the electronic device 10 of the present application can realize a solution of a co-design of a medium-high frequency antenna and an opposite low frequency antenna.

[0101] In 102, when the electronic device 10 is in an overlapping state, the first feed source 320 is controlled to excite the first radiator 310 to support the first wireless signal, the control adjustment module 350 works and controls the second radiator 330 to electromagnetically couple with the first radiator 310 under the excitation of the first feed source 320 and support a third wireless signal, and the third wireless signal is different from the first wireless signal.

[0102] In the overlapping state, the first feed source 320 can be controlled to work and the second feed source 340 can be controlled not to work. At this time, the first feed source 320 can feed the first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal. The second radiator 330 can be electromagnetically coupled with the first radiator 310 under the excitation of the first feed source 320 so as to support the third wireless signal. Under the adjustment action of the adjustment module 350, the third wireless signal supported by the second radiator 330 can be different from the first wireless signal.

[0103] It is understood that, in some embodiments, before step 101, the antenna control method may further include: determining the current state of the electronic device 10. Fig.11 , Fig.11 A second flow chart of the antenna control method provided in the embodiment of the present application, the antenna control method may further include:

[0104] In 201, the current state of the electronic device 10 is determined;

[0105] In 202, when the electronic device 10 is in the unfolded state, the first feed source 320 is controlled to excite the first radiator 310 to support a first wireless signal, and the second feed source 340 is controlled to excite the second radiator 330 to support a second wireless signal, where the second wireless signal is different from the first wireless signal;

[0106] In 203, when the electronic device 10 is in an overlapping state, the first feed source 320 is controlled to excite the first radiator 310 to support the first wireless signal, the control adjustment module 350 works and controls the second radiator 330 to electromagnetically couple with the first radiator 310 under the excitation of the first feed source 320 and support a third wireless signal, and the third wireless signal is different from the first wireless signal.

[0107] It is understandable that a variety of posture sensors may be provided inside the electronic device 10, such as but not limited to a gyroscope, a three-axis sensor, a five-axis sensor, a proximity sensor, etc., and multiple posture sensors may be provided in different areas of the electronic device 10 to detect through multiple posture sensors whether the current state of the electronic device 10 is an unfolded state or an overlapping state.

[0108] It is understandable that the current state of the electronic device 10 can be obtained by detecting the state of the connecting structure 400 such as the rotating shaft. For example, when the electronic device 10 includes a rotating shaft, the electronic device 10 can obtain the opening and closing angle of the rotating shaft, and when the opening and closing angle of the rotating shaft meets the preset angle range (for example, but not limited to the opening and closing angle of the rotating shaft is less than or equal to 60 degrees), it is determined that the electronic device 10 is in the overlapping state; when the opening and closing angle of the rotating shaft does not meet the preset angle range, it is determined that the electronic device 10 is in the unfolded state.

[0109] It is understandable that the current state of the electronic device 10 can also be obtained by detecting the state of the bending angle of the flexible display screen 500. For example, when the bending angle of the flexible display screen 500 is within a preset angle range (for example, but not limited to, the opening and closing angle of the rotating shaft is less than or equal to 60 degrees), it is determined that the electronic device 10 is in an overlapping state; when the bending angle of the flexible display screen 500 is not within the preset angle range, it is determined that the electronic device 10 is in an unfolded state.

[0110] It should be noted that the antenna control method of the present application may also obtain the current state of the electronic device 10 in other ways, and the embodiments of the present application are not limited to this.

[0111] In the unfolded state, the first feed source 320 and the second feed source 340 can be controlled to operate. The first feed source 320 can feed a first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal. The second feed source 340 can feed a second excitation signal to the second radiator 330 to excite the second radiator 330 to support the second wireless signal.

[0112] In the overlapping state, the first feed source 320 can be controlled to work and the second feed source 340 can be controlled not to work. At this time, the first feed source 320 can feed the first excitation signal to the first radiator 310 to excite the first radiator 310 to support the first wireless signal. The second radiator 330 can be electromagnetically coupled with the first radiator 310 under the excitation of the first feed source 320 so as to support the third wireless signal.
