[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0027] An electronic device is provided in the embodiments of the present application. The electronic device may, for example, be a smart phone, a tablet computer, a game device, an AR (Augmented Reality) device, a notebook computer, a desktop computing device, or the like, which has a wireless communication function.

[0028] Reference Figure 1 , Figure 1 A first structure schematic diagram of an electronic device 100 according to an embodiment of the present application is shown in FIG. 1. The electronic device 100 includes a housing 10, a floor 20, a feed source S, a first radiator 31, a second radiator 32, a third radiator 33, and a fourth radiator 34.

[0029] The housing 10 forms a main structure of the electronic device 100, and is used to accommodate various functional components of the electronic device 100. In some embodiments, the housing 10 may, for example, include a middle frame and a battery cover, such as a metal middle frame and a metal battery cover. Functional components such as a main board and a battery may, for example, be arranged inside the housing 10. In actual applications, the housing 10 may, for example, have a rounded rectangular shape as a whole.

[0030] In some embodiments, the housing 10 includes a first side edge 11, a second side edge 12, a third side edge 13, and a fourth side edge 14 connected end to end in sequence. In actual applications, the first side edge 11 and the third side edge 13 may, for example, be short edges, and the second side edge 12 and the fourth side edge 14 may, for example, be long edges. The length of the first side edge 11 and the length of the third side edge 13 are both less than the length of the second side edge 12, and the length of the first side edge 11 and the length of the third side edge 13 are also less than the length of the fourth side edge 14.

[0031] The floor 20 is arranged in the shell 10. Among them, the floor 20 can form a reference ground. In some embodiments, the floor 20 can be formed on the main board of the electronic device 100, or formed on a separate circuit board, or formed on the middle frame. The application does not make specific limitations on the formation of the floor 20. In actual application, the floor 20 can also be a rounded rectangle as a whole.

[0032] In some embodiments, the floor 20 includes a first edge 21 and a second edge 22. The first side edge 11 of the shell 10 is located outside the first edge 21, and the second side edge 12 is located outside the second edge 22. The outside can be understood as the side facing the outside of the electronic device 100, or as the side facing the edge of the electronic device 100. In actual application, the first edge 21 can be parallel to the first side edge 11, and the second edge 22 can be parallel to the second side edge 12. Among them, the first edge 21 and the second edge 22 are bently connected and form a corner 23, and the corner 23 can be a rounded corner.

[0033] The feed source S is arranged in the shell 10. For example, the feed source S can be arranged on the main board in the shell 10, or arranged on a separate circuit board. The feed source S is used to provide an excitation signal. The excitation signal can be an excitation signal for 4G communication, or an excitation signal for 5G communication.

[0034] The first radiator 31, the second radiator 32, the third radiator 33, and the fourth radiator 34 are all arranged spaced apart from the floor 20. The first radiator 31, the second radiator 32, the third radiator 33, and the fourth radiator 34 can all be arranged in the shell 10. In actual application, the first radiator 31, the second radiator 32, the third radiator 33, and the fourth radiator 34 can all be in the form of an antenna radiator such as FPC (Flexible Printed Circuit), LDS (Laser Direct Structure), PDS (Printing Direct Structure), etc., or in the form of an MDA (Mechanical Design Antenna) antenna radiator, for example, in the form of a conductor structure inside the electronic device 100, a metal middle frame, a metal trace on a circuit board, etc. In actual application, the first radiator 31, the second radiator 32, the third radiator 33, and the fourth radiator 34 can be in different forms of antenna radiators, or in the same form of antenna radiators. The form, size, etc. of the first radiator 31, the second radiator 32, the third radiator 33, and the fourth radiator 34 can all be set according to actual needs.

[0035] The first radiator 31 is arranged close to the corner 23. The first radiator 31 includes a feed point 311, for example, the feed point 311 can be arranged at one end of the first radiator 31. The feed source S is electrically connected to the feed point 311 of the first radiator 31 to feed the excitation signal to the first radiator 31. In the embodiment of the present application, the first radiator 31 is electromagnetically coupled to the floor 20. The excitation signal is used to excite the first radiator 31 and the floor 20 to generate resonance of the target frequency band, so as to radiate electromagnetic wave signals of the target frequency band to the outside. It can be understood that in the electromagnetic coupling between the first radiator 31 and the floor 20, the first radiator 31 acts as a capacitive coupling element, and therefore when the first radiator 31 is arranged close to the corner 23, the floor 20 can be fully excited to generate a longitudinal current, wherein the longitudinal direction is parallel to the second side 22.

[0036] In the embodiment of the present application, the target frequency band is a low frequency band (Low Band, LB), and the frequency range of the low frequency band is 690MHz-960MHz. In some embodiments, the target frequency band can include B5, B8, B20, B28 and the like of 4G communication, and can also include N5, N8, N20, N28 and the like of 5G communication.

[0037] In some embodiments, the first radiator 31 and the floor 20 together form a dipole antenna. The first radiator 31 can form one radiating arm of the dipole antenna, and the floor 20 can form the other radiating arm of the dipole antenna. When the feed source S feeds the excitation signal to the first radiator 31, the first radiator 31 and the floor 20 form a dipole antenna to generate resonance of the target frequency band.

[0038] It can be understood that since the target frequency band is a low frequency band, the length of the radiator required in the traditional antenna design is very long. In the embodiment of the present application, the first radiator 31 and the floor 20 together generate resonance of the target frequency band, which can reduce the length of the first radiator 31 while ensuring the performance of wireless communication. Therefore, in the case of limited layout space of the electronic device 100, the space occupied by the first radiator 31 can be reduced, and the layout space of the electronic device 100 can be saved.

[0039] In the embodiment of the present application, the second radiator 32, the third radiator 33 and the fourth radiator 34 are all used to generate resonance of the target frequency band. Therefore, the first radiator 31 and the floor 20, the second radiator 32, the third radiator 33 and the fourth radiator 34 can together form a low frequency MIMO (multiple input multiple output) antenna. By forming a low frequency MIMO antenna, the efficiency of transmitting low frequency electromagnetic wave signals can be improved, thereby improving the communication performance of the electronic device 100.

[0040] In some embodiments, the third radiator 33 forms an IFA (Inverted-F antenna) antenna.

[0041] In some embodiments, the electronic device 100 further comprises a camera module 50, which is mounted to the housing 10. The camera module 50 comprises a camera 51 and a metal decoration 52 which is sleeved on the periphery of the camera 51. The camera 51 can be one or multiple cameras arranged at intervals, for example Figure 1 As shown, the camera 51 can be two cameras arranged at intervals. The metal decoration 52 can be made of metal or alloy, such as aluminum alloy, magnesium alloy, etc. The metal decoration 52 can shield the gap between the camera 51 and the housing 10, thereby playing a decorative role and making the appearance of the electronic device 100 more beautiful.

[0042] The fourth radiator 34 can be formed by the metal decoration 52. It can be understood that the fourth radiator 34 is formed by the metal decoration 52, which can reuse the metal decoration 52 and does not need to separately arrange the fourth radiator 34, thereby saving the layout space inside the electronic device 100.

[0043] In some embodiments, the first radiator 31, the second radiator 32, the third radiator 33, and the fourth radiator 34 can be arranged in a surrounding manner. For example, as shown in Figure 1 The first radiator 31 can be arranged at the corner formed by the connection of the first side 11 and the second side 12, the second radiator 32 can be arranged at the corner formed by the connection of the third side 13 and the fourth side 14, the third radiator 33 can be arranged at one end of the second side 12 close to the third side 13, and the fourth radiator 34 can be arranged at the connection position close to the fourth side 14 and the first side 11.

[0044] It can be understood that in the actual use of the electronic device 100 by the user, some parts of the electronic device 100 can be held by the user, and the probability of the first radiator 31, the second radiator 32, the third radiator 33, and the fourth radiator 34 being held by the user at the same time is very small. Therefore, by arranging in a surrounding manner, the stability of the target frequency band electromagnetic wave signal can be ensured, thereby improving the wireless communication stability of the electronic device 100.

[0045] In some embodiments, referring to Figure 2 , Figure 2 is a schematic view of the relationship between the first radiator 31 of the electronic device of the embodiments of the present application and the floor 20.

[0046] The floor 20 has a current weak point area P1 of the characteristic modal current. The feeding point 311 is located in the current weak point area P1 in the orthographic projection of the floor 20.

[0047] In some embodiments, referring to Figure 3 , Figure 3 is a structural schematic diagram of the floor 20 of the electronic device of embodiments of the present application.

[0048] wherein a region P2 is formed with the intersection O of the extension line of the first edge 21 and the extension line of the second edge 22 as the center and the wavelength of 1 / 16 of the above target frequency band as the radius r, and the above weak point region P1 is located in the region P2.

[0049] In some embodiments, referring to Figure 4 , Figure 4 is a schematic diagram of the connection relationship of the first radiator 31 of the electronic device of embodiments of the present application.

[0050] The electronic device 100 further includes an inductive device 61, which has an inductive characteristic. One end of the inductive device 61 is electrically connected to the first radiator 31, and the other end of the inductive device 61 is electrically connected to the feed source S.

[0051] It can be understood that the inductive device can replace the radiator in size, thereby compensating for the length of the radiator. Therefore, by arranging the inductive device 61, the length of the first radiator 31 can be compensated, thereby further reducing the length of the first radiator 31 and saving the layout space of the electronic device 100.

[0052] In some embodiments, referring to Figure 5 , Figure 5 is a first example of the connection relationship of the first radiator 31 in Figure 4

[0053] wherein the inductive device 61 includes an inductor L0. In one possible example, the inductance value of the inductor L0 can be fixed, and the inductance value can be set according to actual conditions, in which case the frequency range of the above target frequency band is also determined. In another possible example, the inductor L0 can be an adjustable inductor, and the inductance value of the inductor L0 can be adjusted, thereby adjusting the frequency range of the above target frequency band.

[0054] In some embodiments, the electronic device 100 further includes a switching unit. The switching unit has a common terminal and N ports, and the common terminal can be connected or disconnected to any one or more ports. Wherein N is a positive integer, for example, N can be 2, 3, 4, and the like.

[0055] ​The inductive device 61 includes N+1 inductors. The N+1 inductors are connected in series between the first radiator 31 and the feed source S. One end of the N+1 inductors is electrically connected to the first radiator 31, and the other end of the N+1 inductors is electrically connected to the feed source S. The connection points of two adjacent inductors are electrically connected to one of the above-mentioned ports, and different connection points are electrically connected to different ports.

[0056] When the common terminal connects different ports or the common terminal disconnects the above-mentioned N ports, the above-mentioned target frequency band can be switched.

[0057] The following describes an embodiment of the present application by taking N=2 as an example, but it can be understood that N can also be other values in actual application. Referring to Figure 6 , Figure 6 For Figure 4 the second example of the connection relationship of the first radiator 31.

[0058] The above-mentioned switch unit is, for example, the switch unit 62. The switch unit 62 has a common terminal, such as the common terminal RFC. The N ports of the switch unit 62 include a first port a and a second port b. The common terminal RFC can connect or disconnect the first port a and the second port b.

[0059] The N+1 inductors of the inductive device 61 include a first inductor L1, a second inductor L2, and a third inductor L3. The first inductor L1, the second inductor L2, and the third inductor L3 are connected in series. The inductance values of the first inductor L1, the second inductor L2, and the third inductor L3 can be set according to actual requirements. The first inductor L1 is electrically connected to the first radiator 31. The third inductor L3 is electrically connected to the feed source S. The connection point of the first inductor L1 and the second inductor L2 is electrically connected to the first port a. The connection point of the second inductor L2 and the third inductor L3 is electrically connected to the second port b. The connection point of the third inductor L3 and the feed source S is electrically connected to the common terminal RFC.

[0060] When the common terminal RFC connects different ports of the first port a and the second port b, or the common terminal RFC disconnects the first port a and the second port b, the above-mentioned target frequency band can be switched.

[0061] Specifically, when the common terminal RFC connects the first port a, at this time the first inductor L1 is connected into the circuit, the second inductor L2 and the third inductor L3 are short-circuited, the whole presents the inductance value of the first inductor L1, at this time the target frequency band is the first frequency band. When the common terminal RFC connects the second port b, at this time the first inductor L1 and the second inductor L2 are connected in series into the circuit, the third inductor L3 is short-circuited, the whole presents the inductance value of the first inductor L1 and the second inductor L2 connected in series, at this time the target frequency band is the second frequency band. When the common terminal RFC disconnects the first port a and the second port b, at this time the first inductor L1, the second inductor L2 and the third inductor L3 are all connected into the circuit, the whole presents the inductance value of the first inductor L1, the second inductor L2 and the third inductor L3 connected in series, at this time the target frequency band is the third frequency band.

[0062] The center frequencies of the first frequency band, the second frequency band and the third frequency band decrease in turn.

[0063] For example, in some embodiments, the first frequency band is the B8 frequency band of 4G communication, the second frequency band is the B20 frequency band of 4G communication, and the third frequency band is the B28 frequency band of 4G communication. In other embodiments, the first frequency band is the N8 frequency band of 5G communication, the second frequency band is the N20 frequency band of 5G communication, and the third frequency band is the N28 frequency band of 5G communication.

[0064] In some embodiments, the reference Figure 7 , Figure 7 is Figure 4 a third example of the connection relationship of the first radiator 31.

[0065] The switch unit 62 further includes a third port c. The common terminal RFC can connect or disconnect the third port c. The inductive device 61 further includes a fourth inductor L4. One end of the fourth inductor L4 is electrically connected with the third port c, and the other end of the fourth inductor L4 is grounded.

[0066] When the common terminal RFC connects the second port b and the third port c, at this time the third inductor L3 is short-circuited, which is equivalent to that the first inductor L1 is connected in series with the second inductor L2 and then is connected in parallel with the fourth inductor L4. At this time, the target frequency band is the fourth frequency band. The center frequency of the fourth frequency band is smaller than the center frequency of the second frequency band.

[0067] For example, in some embodiments, the fourth frequency band is the B5 frequency band of 4G communication, or the fourth frequency band is the N5 frequency band of 5G communication.

[0068] In some embodiments, the switch unit 62 further includes a fourth port d. The common terminal RFC can connect or disconnect the fourth port d. The inductive device 61 further includes a fifth inductor L5. One end of the fifth inductor L5 is electrically connected with the fourth port d, and the other end of the fifth inductor L5 is grounded.

[0069] When the common end RFC connects the first port a, or connects the second port b, or disconnects the first port a and the second port b, the common end RFC connects or disconnects the fourth port d, so as to switch the transmitting frequency band and the receiving frequency band of the target frequency band.

[0070] For example, when the common end RFC connects the first port a, the common end RFC connects the fourth port d at the same time, at this time the supported frequency band is the transmitting frequency band of the first frequency band; when the common end RFC connects the first port a, the common end RFC disconnects the fourth port d, at this time the supported frequency band is the receiving frequency band of the first frequency band. The same is true for the second frequency band, the third frequency band and the fourth frequency band, which will not be described here.

[0071] In some embodiments, the electronic device 100 further comprises a sixth inductor L6. One end of the sixth inductor L6 is electrically connected between the inductive device 61 and the feed source S, for example, electrically connected between the third inductor L3 and the feed source S; the other end of the sixth inductor L6 is grounded. The sixth inductor L6 is equivalent to a parallel connection of the whole series connection of the first inductor L1, the second inductor L2 and the third inductor L3. Therefore, the sixth inductor L6 can improve the impedance matching state of the first radiator 31 and the feed source S, and improve the performance of wireless communication.

[0072] In some embodiments, referring to Figure 8 , Figure 8 FIG. 2 is a second structural schematic diagram of the electronic device 100 according to an embodiment of the present application.

[0073] The electronic device 100 further comprises a fifth radiator 35, a sixth radiator 36, a seventh radiator 37 and an eighth radiator 38. The fifth radiator 35, the sixth radiator 36, the seventh radiator 37 and the eighth radiator 38 are all arranged spaced apart from the floor 20. In actual applications, the fifth radiator 35, the sixth radiator 36, the seventh radiator 37 and the eighth radiator 38 can all be arranged on the housing 10. The fifth radiator 35, the sixth radiator 36, the seventh radiator 37 and the eighth radiator 38 can all be various forms of antenna radiators such as FPC, LDS, PDS and MDA. In actual applications, the sixth radiator 36 can be formed integrally with the third radiator 33, and the electrical isolation of the sixth radiator 36 and the third radiator 33 can be achieved by grounding at a suitable position of the integral structure.

[0074] The fifth radiator 35, the sixth radiator 36, the seventh radiator 37, and the eighth radiator 38 are used to generate resonance in a middle high band (MHB) to form a middle high band MIMO antenna. The middle high band has a frequency range of 1710-2690 MHz. The middle high band MIMO antenna can improve the efficiency of transmitting middle high band electromagnetic wave signals, thereby improving the communication performance of the electronic device 100.

[0075] In some embodiments, the fifth radiator 35, the sixth radiator 36, the seventh radiator 37, and the eighth radiator 38 are also used to generate resonance in an N41 band to form an N41 band MIMO antenna, thereby improving the efficiency of transmitting electromagnetic wave signals in the N41 band and improving the communication performance. The N41 band has a frequency range of 2515-2675 MHz and 4800-4900 MHz.

[0076] In some embodiments, the fifth radiator 35, the sixth radiator 36, the seventh radiator 37, and the eighth radiator 38 can also have a surrounding layout. For example, as shown in FIG. 6, the fifth radiator 35 can be disposed at one end of the first side 11 close to the second side 12, the sixth radiator 36 can be disposed at one end of the third side 13 close to the second side 12, the seventh radiator 37 can be disposed at the fourth side 14, and the eighth radiator 38 can be disposed at the second side 12. Figure 8

[0077] It can be understood that the fifth radiator 35, the sixth radiator 36, the seventh radiator 37, and the eighth radiator 38 have a surrounding layout, which can reduce the probability that the fifth radiator 35, the sixth radiator 36, the seventh radiator 37, and the eighth radiator 38 are held by a user at the same time. Therefore, the stability of the middle high band electromagnetic wave signals can be ensured, thereby improving the wireless communication stability of the electronic device 100.

[0078] In some embodiments, the electronic device 100 further includes a ninth radiator 39 and a tenth radiator 40. The ninth radiator 39 and the tenth radiator 40 are both disposed apart from the floor 20. In actual applications, the ninth radiator 39 and the tenth radiator 40 can be disposed on the housing 10. For example, the ninth radiator 39 can be disposed at a corner formed by the connection of the first side 11 and the fourth side 14, and the tenth radiator 40 can be disposed at the fourth side 14. The ninth radiator 39 and the tenth radiator 40 can also be various forms of antenna radiators such as FPC, LDS, PDS, and MDA.

[0079] ​The ninth radiator 39 and the tenth radiator 40 are used to generate WIFI resonance of a first frequency sub-band, so as to radiate WIFI signals to the outside world. In some embodiments, the first frequency sub-band is a WIFI 2.4 GHz frequency band.

[0080] In some embodiments, the electronic device 100 further includes an eleventh radiator 41. The eleventh radiator 41 is spaced apart from the floor 20. For example, in some embodiments, the eleventh radiator 41 can be arranged on the mainboard support. The eleventh radiator 41 can be an antenna radiator in the form of FPC, LDS, PDS, etc.

[0081] The first radiator 31, the ninth radiator 39, the tenth radiator 40, and the eleventh radiator 41 are used to generate N78 frequency band resonance of 5G communication, so as to form a MIMO antenna of the N78 frequency band. By forming the MIMO antenna of the N78 frequency band, the transmission efficiency of the N78 frequency band electromagnetic wave signal can be improved, and the communication performance can be improved. The frequency range of the N78 frequency band includes 3400-3500 MHz and 3500-3600 MHz.

[0082] In some embodiments, the electronic device 100 further includes a twelfth radiator 42. The twelfth radiator 42 is spaced apart from the floor 20. In practical applications, the twelfth radiator 42 can be arranged on the shell 10. For example, the twelfth radiator 42 can be arranged on the first side edge 11. The twelfth radiator 42 can be an antenna radiator in various forms such as FPC, LDS, PDS, and MDA.

[0083] The eleventh radiator 41 and the twelfth radiator 42 are used to generate WIFI resonance of a second frequency sub-band, so as to radiate WIFI signals to the outside world. In some embodiments, the second frequency sub-band is a WIFI 5 GHz frequency band.

[0084] In some embodiments, the twelfth radiator 42 is further used to generate GPS L1 frequency band resonance to form a GPS L1 antenna. Thus, the electronic device 100 can support GPS L1 frequency band communication.

[0085] In some embodiments, the electronic device 100 further includes a thirteenth radiator 43. The thirteenth radiator 43 is spaced apart from the floor 20. For example, in some embodiments, the thirteenth radiator 43 can be arranged on the mainboard support. The thirteenth radiator 43 can be an antenna radiator in the form of FPC, LDS, PDS, etc.

[0086] The thirteenth radiator 43 is used to generate GPS L5 frequency band resonance to form a GPS L5 antenna. Thus, the electronic device 100 can support GPS L5 frequency band communication.

[0087] It can be understood that the GPS L1 antenna is formed by the twelfth radiator 42, and the GPS L5 antenna is formed by the thirteenth radiator 43, so that the electronic device 100 can support dual-frequency GPS communication, thereby improving the efficiency and stability of GPS communication.

[0088] In actual applications, the first radiator 31 to the thirteenth radiator 43 can form antennas ANT-1, ANT-2, ANT-3, ANT-4, ANT-5, ANT-6, ANT-7, ANT-8, ANT-9, ANT-10, ANT-11, ANT-12, and ANT-13 in sequence. In an application example, the communication frequency bands supported by each antenna are as follows:
