[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only some embodiments of the present application, rather than all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

[0021] The embodiments of the present application provide an electronic device. The electronic device can be, for example, a device with wireless communication functions such as a smart phone, a tablet computer, a game device, an AR (Augmented Reality) device, a notebook computer, a desktop computing device, etc.

[0022] Refer to Figure 1 , Figure 1 It is the first structural schematic diagram of the electronic device 100 in the embodiments of the present application.

[0023] The electronic device 100 includes a main body 11. The main body 11 forms the main body part of the whole electronic device 100. In practical applications, functional components such as a main board and a battery module can be arranged inside the main body 11, and functional components such as a display screen can also be arranged on the main body 11.

[0024] Among them, the main body 11 includes a first side 111, a second side 112, a third side 113, and a fourth side 114 that are connected end to end in sequence. The first side 111 is opposite to the third side 113, and the second side 112 is opposite to the fourth side 114. The first side 111 and the third side 113 are short sides, and the second side 112 and the fourth side 114 are long sides, that is, the lengths of the first side 111 and the third side 113 are both smaller than the lengths of the second side 112 and the fourth side 114.

[0025] In practical applications, the first side 111 can be located at the bottom 11a of the electronic device 100; the third side 113 can be located at the top 11b of the electronic device 100; the second side 112 can be located at the side of the electronic device 100, such as the left side; the fourth side 114 can be located at the side of the electronic device 100, such as the right side. The second side 112 and the third side 113 are connected to form a corner 11c. Among them, the bottom 11a and the top 11b are arranged in opposite directions, the top 11b includes the corner 11c, and the left side and the right side are arranged in opposite directions. During the process of the user vertically holding and using the electronic device 100, the bottom 11a faces downward, the top 11b faces upward, and the left side and the right side are respectively located on both sides of the electronic device 100.

[0026] In some embodiments, the electronic device 100 further includes a main board 31 and a battery module 32. The main board 31 and the battery module 32 are both arranged inside the main body 11. Among them, the main board 31 is close to the third side 113, that is, close to the top 11b; the battery module 32 is close to the first side 111, that is, close to the bottom 11a. The battery module 32 is electrically connected to the main board 31 for supplying power to the main board 31. It can be understood that in practical applications, functional components such as a processor, a memory, a baseband chip, and a camera module can be arranged on the main board 31 to implement functions such as data processing, communication, and photographing.

[0027] In the embodiments of the present application, the electronic device 100 further includes a first antenna 21, a second antenna 22, and a third antenna 23. The first antenna 21, the second antenna 22, and the third antenna 23 are arranged at intervals from each other.

[0028] In practical applications, the first antenna 21, the second antenna 22, and the third antenna 23 can each include an antenna radiator in the form of, for example, an FPC (Flexible Printed Circuit), an LDS (Laser Direct Structure), a PDS (Printing Direct Structure), etc., can also include an antenna radiator in the form of MDA (in-mold injection), and can further include an antenna radiator formed by a conductor structure of an electronic device, a metal trace on a circuit board, and other structures.

[0029] Among them, at least a part of the first antenna 21 is disposed on the first side 111. For example, the first antenna 21 can be disposed on the first side 111 and extend towards the second side 112 and the fourth side 114 at both ends respectively. In practical applications, the first antenna 21 can be understood as being disposed on the bottom 11a. The first antenna 21 covers the middle high band (MHB) and the low band (LB). For example, in some embodiments, the first antenna 21 can be configured as a middle high band primary antenna (MHB PRX) and a low band diversity antenna (LB DRX).

[0030] At least a part of the second antenna 22 is disposed on the third side 113. For example, the second antenna 22 can be disposed on the third side 113 and extend towards the fourth side 114 at one end. In practical applications, the second antenna 22 can be understood as being disposed on the top 11b. The second antenna 22 covers the middle high band (MHB) and the low band (LB). For example, in some embodiments, the second antenna 22 can be configured as a middle high band diversity antenna (MHB DRX) and a low band primary antenna (LB PRX).

[0031] At least a part of the third antenna 23 is disposed at the corner 11c. For example, the third antenna 23 can be disposed at the corner 11c and extend towards the second side 112 and the third side 113 at both ends respectively. The third antenna 23 covers WiFi communication and the low band (LB). For example, in some embodiments, the third antenna 23 can be configured as a WiFi antenna and a low band diversity antenna (LB DRX). In practical applications, the second antenna 23 can simultaneously cover the 2.4 GHz band and the 5 GHz band of WiFi communication to expand the bandwidth of WiFi communication. It can be understood that in practical applications, the WiFi excitation signal and the low band excitation signal can be combined and fed into the third antenna 23 to excite the third antenna 23 to support both WiFi communication and low band (LB) communication simultaneously.

[0032] It can be understood that setting the third antenna 23 that covers WiFi communication and low frequency (LB) at the corner 11c can make full use of the corner space of the electronic device. When it is set at the corner 11c, during the user's use of the electronic device, the third antenna 23 is not easily blocked by the user's hand, thus ensuring the performance of WiFi communication and low-frequency communication.

[0033] In some embodiments, the frequency range of the above medium-high frequency includes 1710 MHz to 2690 MHz. Among them, the medium-high frequency may include at least one frequency band of N41 (frequency range 2496 MHz to 2690 MHz) and N7 (2500 MHz to 2690 MHz).

[0034] The frequency range of the above low frequency includes 690 MHz to 960 MHz. Among them, the low frequency may include at least one frequency band of B5 (frequency range 824 MHz to 894 MHz), B8 (frequency range 880 MHz to 960 MHz), B20 (frequency range 791 MHz to 862 MHz), and B28 (frequency range 703 MHz to 803 MHz).

[0035] In some embodiments, referring to Figure 2 , Figure 2 is a schematic diagram of the S-parameter simulation of the third antenna 23 of the electronic device implemented in this application.

[0036] Among them, the curve L1 (S1,1 curve) is the S-parameter debugging waveform of WiFi, and the curve L2 (S2,2 curve) is the S-parameter debugging waveform of the low frequency. The marked point 1 is the WiFi resonance frequency point of the 2.4 GHz frequency band, the resonance frequency is about 2.45 GHz, and the resonance amplitude is about -18.33 dB. The marked point 2 is the WiFi resonance frequency point of the 5 GHz frequency band, the resonance frequency is about 5.51 GHz, and the resonance amplitude is about -16.63 dB. The marked point 3 is the resonance frequency point of the low frequency, the resonance frequency is about 0.75 GHz, and the resonance amplitude is about -6.96 dB. It can be Figure 2 seen that the third antenna 23 has good resonance characteristics.

[0037] In the electronic device 100 of the embodiment of the present application, both the first antenna 21 and the second antenna 22 cover the medium-high frequency and the low frequency, and the third antenna 23 covers WiFi communication and the low frequency, which can realize the design of three low-frequency antennas. Moreover, the third low-frequency antenna is integrated with the WiFi antenna and set at the corner of the electronic device. Therefore, there is no need to separately set a third low-frequency antenna additionally, and it will not increase the occupation of the layout space of the electronic device. Therefore, the overall design of the antenna can be simplified, and the antenna performance can meet the requirements.

[0038] In some embodiments, referring to Figure 3 , Figure 3This is the second schematic diagram of the electronic device 100 implemented in this application.

[0039] Among them, a signal source 311 is provided on the main board 31. The signal source 311 is electrically connected to the second antenna 22. The signal source 311 is used to provide an excitation signal, for example, to provide a medium-high frequency excitation signal and a low-frequency excitation signal, and feed the excitation signal into the second antenna 22 to excite the second antenna 22 to radiate wireless signals to the outside world, realizing medium-high frequency and low-frequency communication.

[0040] The electronic device 100 further includes a small board 33 and a radio frequency transmission line 34. The small board 33 is a relatively small circuit board independent of the main board 31. The small board 33 is disposed within the main body portion 11 and is close to the first side 111. In practical applications, the small board 33 can be understood as being disposed at the bottom 11a.

[0041] Among them, a signal transmission circuit 331 is provided on the small board 33. The signal transmission circuit 331 is electrically connected to the signal source 311 through the radio frequency transmission line 34, and the signal transmission circuit 331 is electrically connected to the first antenna 21. Therefore, the signal source 311 can feed the excitation signal into the first antenna 21 through the radio frequency transmission line 34 and the signal transmission circuit 331 on the small board 33 to excite the first antenna 21 to radiate wireless signals to the outside world, realizing medium-high frequency and low-frequency communication.

[0042] In some embodiments, refer to Figure 4 , Figure 4 This is the third schematic diagram of the electronic device 100 implemented in this application.

[0043] The electronic device 100 further includes any one or more of a fourth antenna 24, a fifth antenna 25, a seventh antenna 27, and an eighth antenna 28. The fourth antenna 24, the fifth antenna 25, the seventh antenna 27, and the eighth antenna 28 can all include antenna radiators in forms such as FPC, LDS, PDS, etc., can also include antenna radiators in the form of MDA, and can also include antenna radiators formed by conductor structures of the electronic device, metal traces on the circuit board, and other structures.

[0044] Among them, the fourth antenna 24 is disposed on the second side 112 and is close to the third antenna 23. The fourth antenna 24 covers medium-high frequency (MHB) and ultra-high frequency (UHF).

[0045] The fifth antenna 25 is disposed on the fourth side 114 and is close to the second antenna 22. The fifth antenna 25 covers medium-high frequency (MHB) and ultra-high frequency (UHF).

[0046] The seventh antenna 27 is disposed on the second side 112 and is close to the fourth antenna 24. The seventh antenna 27 covers ultra-high frequency UHF.

[0047] The eighth antenna 28 is disposed on the third side 113. The eighth antenna 28 is located between the second antenna 22 and the third antenna 23. The eighth antenna 28 covers GPS (Global Positioning System) communication and ultra-high frequency (UHF).

[0048] It can be understood that in practical applications, the fourth antenna 24, the fifth antenna 25, the seventh antenna 27, and the eighth antenna 28 can be set in the electronic device 100 at the same time, or only a part of them can be set.

[0049] In some embodiments, the ultra-high frequency (UHF) may include the N78 (frequency range 3300 MHz to 3800 MHz) band.

[0050] In an example of practical application, the fourth antenna 24 can be configured as a medium-high frequency diversity MIMO (multiple input multiple output) antenna (MHB DRX MIMO) and an N78 diversity antenna (N78 DRX). The fifth antenna 25 can be configured as a medium-high frequency main set MIMO antenna (MHB PRX MIMO) and an N78 main set antenna (N78 PRX). The seventh antenna 27 can be configured as an N78 diversity antenna (N78 DRX). The eighth antenna 28 can be configured as a GPS L1 band antenna and an N78 main set MIMO antenna (N78 PRX MIMO).

[0051] In an example of practical application of the electronic device 100 according to the embodiment of the present application, the communication frequency bands supported by each antenna are configured as follows:

[0052] The first antenna 21: MHB PRX, LB DRX;

[0053] The second antenna 22: MHB DRX, LB PRX;

[0054] The third antenna 23: WiFi 2.4 GHz / 5 GHz, LB DRX;

[0055] The fourth antenna 24: MHB DRX MIMO, N78 DRX MIMO;

[0056] The fifth antenna 25: MHB PRX MIMO, N78 PRX;

[0057] The seventh antenna 27: N78 DRX;

[0058] The eighth antenna 28: GPS L1, N78 PRX MIMO.

[0059] Among them, PRX represents the main set antenna, DRX represents the diversity antenna, and MIMO represents multiple-input multiple-output.

[0060] Therefore, by configuring the first antenna 21, the second antenna 22, and the third antenna 23, the main set and diversity transmissions of MHB can be achieved, the three-antenna transmission of LB can be achieved, and the dual-band transmission of WiFi can be achieved. By configuring the fourth antenna 24, the fifth antenna 25, the seventh antenna 27, and the eighth antenna 28, the MIMO transmission of MHB can be achieved, the MIMO transmission of N78 can be achieved, and GPS communication can be achieved.

[0061] In addition, in the electronic device 100 of the embodiment of the present application, except for the first antenna 21, other antennas are all arranged near the main board 31, and no more radio frequency transmission lines need to be set. Therefore, only one radio frequency transmission line 34 is required in the embodiment of the present application, which can reduce the number of required radio frequency transmission lines, thereby saving the overall antenna cost.

[0062] In some embodiments, refer to Figure 5 , Figure 5 which is the fourth structural schematic diagram of the electronic device 100 implemented in the present application.

[0063] The electronic device 100 further includes any one or more of the fourth antenna 24, the fifth antenna 25, the sixth antenna 26, the seventh antenna 27, and the eighth antenna 28. Among them, the settings and functions of the fourth antenna 24, the seventh antenna 27, and the eighth antenna 28 are the same as those in the Figure 4 shown electronic device, and can refer to the description in the above embodiments, which will not be repeated here. In practical applications, the fourth antenna 24, the seventh antenna 27, and the eighth antenna 28 can be set in the electronic device 100 at the same time, or only a part of them can be set. The settings and functions of the fifth antenna 25 and the sixth antenna 26 will be described below.

[0064] Among them, both the fifth antenna 25 and the sixth antenna 26 can include antenna radiators in forms such as FPC, LDS, PDS, etc., can also include antenna radiators in the form of MDA, and can also include antenna radiators formed by the conductor structure of the electronic device, metal traces on the circuit board, and other structures.

[0065] The fifth antenna 25 is arranged on the fourth side 114 and is close to the second antenna 22. The fifth antenna 25 covers the middle frequency (MiddleBand, MB) and the ultra-high frequency (UHB). The sixth antenna 26 is arranged on the fourth side 114 and is close to the fifth antenna 25. The sixth antenna 26 covers the high frequency (High Band, HB). Among them, the ultra-high frequency (UHB) can include the N78 band.

[0066] It can be understood that the high-frequency (HB) in the medium-high frequency (MHB) covered by the fifth antenna 25 in the above embodiment is split out and configured as the sixth antenna 26 to cover the high-frequency (HB). For example, the N41 frequency band (the N41 frequency band belongs to the high-frequency) in the medium-high frequency (MHB) is split out, so that the sixth antenna 26 covers the N41 frequency band.

[0067] In an example of actual application, for the electronic device 100 according to the embodiment of the present application, the communication frequency bands supported by each antenna are configured as follows:

[0068] The first antenna 21: MHB PRX, LB DRX;

[0069] The second antenna 22: MHB DRX, LB PRX;

[0070] The third antenna 23: WiFi 2.4GHz / 5GHz, LB DRX;

[0071] The fourth antenna 24: MHB DRX MIMO, N78 DRX MIMO;

[0072] The fifth antenna 25: MB PRX MIMO, N78 PRX;

[0073] The sixth antenna 26: N41 MIMO;

[0074] The seventh antenna 27: N78 DRX;

[0075] The eighth antenna 28: GPS L1, N78 PRX MIMO.

[0076] Among them, PRX represents the main set antenna, DRX represents the diversity antenna, and MIMO represents multiple input and multiple output.

[0077] Therefore, in the embodiment of the present application, by configuring the first antenna 21, the second antenna 22, and the third antenna 23, the main set and diversity transmission of MHB can be realized, as well as the three-antenna transmission of LB and the dual-band transmission of WiFi. By configuring the fourth antenna 24, the fifth antenna 25, the sixth antenna 26, the seventh antenna 27, and the eighth antenna 28, the MIMO transmission of MHB (MHB includes the N41 frequency band) can be realized, as well as the MIMO transmission of N78 and the GPS communication.

[0078] It can be understood that Figure 5 the shown electronic device compared with Figure 4For the electronic device shown, since the HB (such as the N41 frequency band) in the MHB covered by the fifth antenna 25 is split out and the N41 frequency band is covered by the sixth antenna 26, the fifth antenna 25 does not need to switch frequency bands between the MB and HB through an antenna switch, thus simplifying the design of the antenna switch.

[0079] In some embodiments, refer to Figure 6 , Figure 6 which is the fifth schematic structural diagram of the electronic device 100 implemented in this application.

[0080] The electronic device 100 further includes a first tuning module M1, a second tuning module M2, a third tuning module M3, and a fourth tuning module M4. In practical applications, the first tuning module M1, the second tuning module M2, the third tuning module M3, and the fourth tuning module M4 can all be disposed on the circuit board of the electronic device, such as on the main board, or can also be disposed on an independent small board. Among them, the first tuning module M1, the second tuning module M2, the third tuning module M3, and the fourth tuning module M4 are all impedance modules and can include at least one of impedance elements such as inductors, capacitors, and resistors. The first tuning module M1, the second tuning module M2, the third tuning module M3, and the fourth tuning module M4 are all grounded.

[0081] The first tuning module M1 is electrically connected to the first antenna 21 and is used to switch the frequency band of the low frequency (LB) supported by the first antenna 21.

[0082] The second tuning module M2 is electrically connected to the second antenna 22 and is used to switch the frequency band of the low frequency (LB) supported by the second antenna 22.

[0083] The third tuning module M3 is electrically connected to the fourth antenna 24 and is used to switch the frequency band of the medium-high frequency (MHB) supported by the fourth antenna 24.

[0084] The fourth tuning module M4 is electrically connected to the fifth antenna 25 and is used to switch the frequency band of the medium-high frequency (MHB) supported by the fifth antenna 25.

[0085] It should be noted that when the antennas of the electronic device 100 are configured as Figure 4 shown, the fourth tuning module M4 can be set to switch the frequency band of the medium-high frequency (MHB) supported by the fifth antenna 25. When the antennas of the electronic device 100 are configured as Figure 5 shown, since the high frequency (HB) in the medium-high frequency (MHB) covered by the fifth antenna 25 is split out and configured as the sixth antenna 26 to cover the high frequency (HB), in this case, the fifth antenna 25 no longer needs to cover the high frequency (HB) and does not need to switch between the intermediate frequency (MB) and the high frequency (HB). Therefore, in this case, the fourth tuning module M4 does not need to be set.

[0086] In some embodiments, referring to Figure 7 , Figure 7 is a schematic structural diagram of a first tuning module M1 of an electronic device according to an embodiment of the present application. It should be noted that in practical applications, the structures of the second tuning module M2, the third tuning module M3, and the fourth tuning module M4 may be the same as that of the first tuning module M1, but the specific impedance parameters may be different. Therefore, only the structure of the first tuning module M1 is taken as an example for illustration here, and the structures of the second tuning module M2, the third tuning module M3, and the fourth tuning module M4 may be referred to together with Figure 7 .

[0087] Among them, the first tuning module M1 includes a plurality of tuning paths and a switching switch K.

[0088] In some embodiments, the plurality of tuning paths may include 4 tuning paths, such as tuning path a, tuning path b, tuning path c, and tuning path d. It can be understood that in other embodiments, the number of tuning paths may also be other numbers, such as 2, 3, 6, etc. Each tuning path is grounded. In practical applications, each tuning path may include one or more impedance elements such as inductors, capacitors, and resistors, and there may also be a tuning path among the plurality of tuning paths that does not include any impedance elements. Among them, different tuning paths have different impedances, for example, the impedances of tuning path a, tuning path b, tuning path c, and tuning path d are different from each other.

[0089] One end of the switching switch K is electrically connected to the first antenna 21. The other end of the switching switch K can be connected to any one of the tuning paths, for example, it can be connected to any one of tuning path a, tuning path b, tuning path c, and tuning path d, so that the first antenna 21 is connected to any one of tuning path a, tuning path b, tuning path c, and tuning path d. Therefore, the matching impedance of the first antenna 21 can be changed, thereby realizing the switching of the communication frequency band of the first antenna 21.

[0090] In practical applications, the switching switch K may be a switch having a single-pole multi-throw function formed by components such as transistors and switching tubes, for example, a switch having a single-pole four-throw function.

[0091] In some embodiments, referring to Figure 8 , Figure 8 is a sixth schematic structural diagram of the electronic device 100 according to the present application. Only the parts of the electronic device 100 that are different from the electronic device 100 in the above embodiments are described below. The same parts can be referred to the descriptions in the above embodiments and will not be repeated here.

[0092] The first antenna 21 covers the first frequency band, the second frequency band, and the third frequency band of the medium-high frequency (MHB) and the low frequency (LB). The second antenna 22 covers the second frequency band of the medium-high frequency (MHB) and the low frequency (LB). The third antenna 23 covers WiFi communication, for example, it can cover the 2.4GHz frequency band and the 5GHz frequency band of WiFi communication simultaneously. The fifth antenna 25 covers the third frequency band of the medium frequency (MB) and the low frequency (LB).

[0093] In some embodiments, the first frequency band is one of B5, B8, B20, and B28, the second frequency band is another one of B5, B8, B20, and B28, and the third frequency band is another one different from the first frequency band and the second frequency band among B5, B8, B20, and B28. For example, the first frequency band can be B28, the second frequency band can be B5, and the third frequency band can be B8.

[0094] In the embodiments of the present application, the first antenna 21 can be a broadband antenna, which covers the first frequency band, the second frequency band, and the third frequency band of the low frequency (LB) simultaneously. For example, it can cover the three frequency bands of B5, B8, and B28 simultaneously, and there is no need to switch the frequency band through an antenna switch. Therefore, the first tuning module M1 in the above embodiments can be omitted. The second antenna 22 covers one frequency band in the low frequency (LB), that is, the second frequency band. Therefore, there is also no need to switch the frequency band through an antenna switch, and the second tuning module M2 in the above embodiments can be omitted.

[0095] It can be understood that in the embodiments of the present application, since the fifth antenna 25 needs to cover the third frequency band of the low frequency (LB), such as B8, the length of the fifth antenna 25 needs to be designed relatively long, occupying more layout space. In this case, in order to prevent the sixth antenna 26 from affecting the antenna performance when approaching the area where the battery module 32 is located, the sixth antenna 26 can be arranged on the main board 31, for example, it can be arranged on the antenna bracket of the main board 31.

[0096] In an example of the actual application of the electronic device 100 according to the embodiments of the present application, the communication frequency bands supported by each antenna are configured as follows:

[0097] The first antenna 21: MHB PRX, LB DRX;

[0098] The second antenna 22: MHB DRX, LB PRX (such as B5);

[0099] The third antenna 23: WiFi 2.4GHz / 5GHz;

[0100] The fourth antenna 24: MHB DRX MIMO, N78 DRX MIMO;

[0101] Fifth Antenna 25: LB (e.g., B8), MB PRX MIMO, N78 PRX;

[0102] Sixth Antenna 26: N41 MIMO;

[0103] Seventh Antenna 27: N78 DRX;

[0104] Eighth Antenna 28: GPS L1, N78 PRX MIMO.

[0105] Among them, PRX represents the main set antenna, DRX represents the diversity antenna, and MIMO represents multiple-input multiple-output.

[0106] In the embodiments of the present application, through the configuration of the first antenna 21, the second antenna 22, and the fifth antenna 25, the main set and diversity transmissions of MHB can also be realized, and the three-antenna transmission of LB can be realized.

[0107] In addition, in practical applications, when the electronic device 100 is not in the version required by the communication operator, the required frequency band of the medium and high frequency (MHB) is reduced. Therefore, the fourth antenna 24 does not need to switch the frequency band through the antenna switch, and the third tuning module M3 in the above embodiments can be saved. In addition, by covering the N41 frequency band with the sixth antenna 26, the fifth antenna 25 does not need to switch the frequency band through the antenna switch, and the fourth tuning module M4 in the above embodiments can be saved.

[0108] Therefore, the electronic device 100 in the embodiments of the present application can omit all of the first tuning module M1, the second tuning module M2, the third tuning module M3, and the fourth tuning module M4 in the above embodiments, and implement the design of 0 antenna switches, so that the overall antenna cost can be reduced.
