Description

Technical Field

[0001] The present application relates to the technical field of electronic products, and in particular to an electronic device. Background Art

[0002] With the continuous development of communication technology, there are more and more antenna bands, so more antennas need to be deployed in electronic devices to be compatible with more bands. In order to ensure the performance of the antenna, some antennas need to be designed in specific positions of electronic devices, such as being set at the top (such as the side where the receiver, front camera, etc. are located) to ensure that the antenna has good upper hemisphere efficiency, such as the Global Positioning System (GPS) band, the medium and high frequency band (MHB), the Near Field Communication (NFC) band, the wireless network (WIFI) band, the n78 band, etc. Due to the limited space of electronic devices, when the number of antenna bands deployed is large, especially when more antennas need to be arranged in the same specific position, there may be interference between antennas of different frequency bands, or between antennas and devices such as the front camera sound cavity, which increases the difficulty of de-isolation and increases the matching loss caused by the increase of de-isolation circuits. Therefore, the antenna design in current electronic devices has the problem that the antenna performance at a specific position and the isolation requirements cannot be compatible. Summary of the invention

[0003] An embodiment of the present application provides an electronic device to solve the problem that antenna design in current electronic devices is incompatible with meeting antenna performance requirements at a specific location and ensuring isolation requirements.

[0004] In order to solve the above technical problems, this application is implemented as follows:

[0005] An embodiment of the present application provides an electronic device, comprising: a first antenna radiator, a first insulating medium, and a second insulating medium;

[0006] The first antenna radiator is arranged along a first side and a second side of the electronic device, and the first antenna radiator is used to cover a first frequency band; wherein the first side and the second side are arranged adjacent to each other;

[0007] The first insulating medium covers a first portion of the first antenna radiator, and the second insulating medium covers a second portion of the first antenna radiator; wherein the dielectric constant of the first insulating medium is smaller than the dielectric constant of the second insulating medium, and the first portion and the second portion are different portions on the first antenna radiator.

[0008] Thus, in the above scheme of the present application, by setting a first insulating medium with a lower dielectric constant to cover the first part of the first antenna radiator, and setting a second insulating medium with a higher dielectric constant to cover the second part of the first antenna radiator, the electromagnetic wave of the first antenna radiator can be biased toward the first side of the first electronic device where the first part is located and radiated from the medium into the air, that is, the efficiency of the first frequency band covered by the first antenna radiator on the first side is guaranteed. In addition, the second part of the first antenna radiator is set on the second side of the first antenna device, which also avoids occupying the space of the first side of the first electronic device, reduces the mutual interference with the antenna set on the first side, and meets the isolation requirement.

[0018] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0019] like Figure 1 As shown, an embodiment of the present application provides an electronic device, comprising: a first antenna radiator 10, a first insulating medium 11 and a second insulating medium 12;

[0020] The first antenna radiator 10 is disposed along a first side and a second side of the electronic device, and the first antenna radiator 10 is used to cover a first frequency band; wherein the first side and the second side are adjacently disposed.

[0021] The first insulating medium 11 covers a first part of the first antenna radiator 10, and the second insulating medium 12 covers a second part of the first antenna radiator 10; wherein the dielectric constant of the first insulating medium 11 is smaller than the dielectric constant of the second insulating medium 12, and the first part and the second part are different parts on the first antenna radiator 10.

[0022] For example, the first antenna radiator 10 is used as a carrier of radiated electromagnetic wave energy to cover a first frequency band.

[0023] Optionally, a bending portion is provided on the first antenna radiator 10, and the radiator between the bending portion and the first end of the first antenna radiator 10 is located at the first side of the electronic device. The radiator between the bending portion and the second end of the first antenna radiator 10 is located at the second side of the electronic device. Optionally, the first side may be the top side of the electronic device, that is, the first side is located at the top of the electronic device, and the second side is the side adjacent to the top side.

[0024] Optionally, the first part may be the radiator between the bending portion and the first end of the first antenna radiator 10, and the second part may be the radiator between the bending portion and the second end of the first antenna radiator 10; or, the first part may include: the radiator between the bending portion and the first end of the first antenna radiator 10, and a part of the radiator between the bending portion and the second end of the first antenna radiator 10, and the second part may include: another part of the radiator between the bending portion and the second end of the first antenna radiator 10, etc. The embodiments of the present application are not limited to this.

[0025] like Figure 2 As shown, the antenna radiator 1 is in the insulating medium 2, that is, the insulating medium 2 covers the antenna radiator 1. The calculation formula of the wave impedance is:

[0026]

[0027] Among them, z is the wave impedance, E is the electric field intensity, H is the magnetic field intensity, u is the magnetic permeability, and ε is the dielectric constant.

[0028] Based on the above wave impedance calculation formula, it can be calculated that the wave impedance in the air is 376.7 ohms (the dielectric constant of air is 1.0006, which is close to the dielectric constant of vacuum, which is about 1). Since the wave impedance z in the medium is inversely proportional to the dielectric constant ε, if the dielectric constant ε is larger, the wave impedance z in the medium is smaller, and the difference with the wave impedance in the air is also larger. The corresponding electromagnetic waves will be more difficult to radiate from the medium to the air, which is manifested as the medium with a high dielectric constant has a stronger ability to bind electromagnetic waves. On the contrary, the wave impedance of a low dielectric constant is closer to the wave impedance of air, which is more conducive to the radiation of electromagnetic waves from the medium to the air.

[0029] Thus, in the embodiment of the present application, by setting a first insulating medium 11 with a lower dielectric constant to cover the first part of the first antenna radiator 10, and setting a second insulating medium 12 with a higher dielectric constant to cover the second part of the first antenna radiator 10, the electromagnetic wave of the first antenna radiator 10 can be biased to the first side of the first electronic device where the first part is located, and radiated from the medium to the air. For example, the first side is located at the top of the electronic device, which ensures the upper hemisphere efficiency of the first frequency band covered by the first antenna radiator 10. In addition, the second part of the first antenna radiator 10 is arranged on the second side of the first antenna device, which also avoids the space occupation of the first side of the first electronic device, reduces the mutual interference between the antennas, and the mutual interference between the antenna and the front camera sound cavity and other devices, meets the isolation requirements, and can also avoid the increase in matching loss caused by increasing the isolation circuit, solving the problem that the antenna design in the current electronic device is incompatible with meeting the antenna performance at a specific location and ensuring the isolation requirements.

[0030] Take the case where the first side is located at the top of the electronic device as an example. Figure 3A As shown, a schematic diagram of antenna radiation direction with different dielectric constants of the first insulating medium 11 and the second insulating medium 12 is given, for example, the dielectric constant of the first insulating medium 11 is 1, and the dielectric constant of the second insulating medium 12 is 6. Figure 3B As shown, a schematic diagram of the antenna radiation direction when the dielectric constants of the first insulating medium 11 and the second insulating medium 12 are the same is given, for example, the dielectric constants of the first insulating medium 11 and the second insulating medium 12 are both 3. It can be seen that when the dielectric constants of the first insulating medium 11 and the second insulating medium 12 are different and the difference is large, the antenna radiation pattern is obviously biased toward the top.

[0031] Will be like Figure 3A and Figure 3B Compare the antenna radiation pattern in Figure 3CAs shown, it can be seen that when the dielectric constants of the first insulating medium 11 and the second insulating medium 12 are both 3, the upper hemisphere efficiency is 51%, and when the dielectric constant of the first insulating medium 11 is 1 and the dielectric constant of the second insulating medium 12 is 6, the upper hemisphere efficiency is 66%. That is to say, in the scheme of the present application, since the first insulating medium 11 with a low dielectric constant is closer to the air wave impedance than the second insulating medium 12 with a high dielectric constant, it is more conducive to the radiation of electromagnetic waves from the medium into the air, meeting the upper hemisphere efficiency requirements, reducing the top space occupied by electronic equipment, reducing mutual interference between antennas, and mutual interference between antennas and devices such as the front camera sound cavity, and meeting the isolation requirements.

[0032] It should be noted that the first insulating medium 11 described in the embodiment of the present application refers to the overall dielectric constant (or equivalent dielectric constant) constituting the first insulating medium 11, and similarly, the dielectric constant of the second insulating medium 12 refers to the overall dielectric constant (or equivalent dielectric constant) constituting the second insulating medium 12. For example, if the first insulating medium 11 or the second insulating medium 12 is made of a single insulating material, the equivalent dielectric constant of the first insulating medium 11 or the second insulating medium 12 is determined by the dielectric constant of the insulating material and the structural characteristics of the first insulating medium 11 or the second insulating medium 12; if the first insulating medium 11 or the second insulating medium 12 is made of multiple insulating materials, the equivalent dielectric constant of the first insulating medium 11 or the second insulating medium 12 is jointly determined by the dielectric constants of the multiple insulating materials, etc. The embodiment of the present application is not limited thereto.

[0033] Alternatively, if Figure 4 As shown, the first insulating medium 11 is made of a first insulating material, and the second insulating medium 12 is made of a second insulating material; wherein the dielectric constant of the first insulating material is smaller than the dielectric constant of the second insulating material.

[0034] For example: based on injection molding, filling or spraying, the first insulating material can be used to prepare the first insulating medium 11 on the surface of the first part of the first antenna radiator 10, and the second insulating material can be used to prepare the second insulating medium 12 on the surface of the second part of the first antenna radiator 10, that is, the equivalent dielectric constant of the first insulating medium 11 can be considered as the dielectric constant of the first insulating material, and the equivalent dielectric constant of the second insulating medium 12 can be considered as the dielectric constant of the second insulating material. In this way, by selecting the dielectric constant of the first insulating material to be smaller than the dielectric constant of the second insulating material, the dielectric constant of the first insulating medium 11 can be smaller than the dielectric constant of the second insulating material, thereby ensuring the efficiency of the first frequency band covered by the first antenna radiator 10 on the first side of the electronic device.

[0035] Optionally, a first grounding point 101 and a first feeding point 102 are provided on the first antenna radiator 10; the distance from the first grounding point 101 to the first end on the first antenna radiator 10 is smaller than the distance from the first feeding point 102 to the first end; wherein the first part is the radiator on the first antenna radiator 10 from the first feeding point 102 to the first end, and the first side is located at the top of the electronic device.

[0036] Optionally, the second portion may be a portion of the first antenna radiator 10 other than the first portion, that is, the second portion is a radiator on the first antenna radiator 10 from the first feeding point 102 to the second end of the first antenna radiator 10. The first end and the second end are two ends on the first antenna radiator 10.

[0037] In this embodiment, the first part and the second part of the first antenna radiator 10 are divided based on the position of the first feeding point 102, so that the first frequency band covered by the first antenna radiator 10 has a higher efficiency at the first side of the electronic device. And the first side is located at the top of the electronic device, that is, the upper hemisphere efficiency of the first frequency band covered by the first antenna radiator 10 can be guaranteed.

[0038] If you continue to see Figure 1 , part of the radiator between the first ground point 101 and the second end of the first antenna radiator 10 works in the inverted-F antenna (IFA) mode, as the main radiator part covering the first frequency band, and the current distribution direction is A2. Part of the radiator between the first ground point 101 and the first end of the first antenna radiator 10 works in the monopole mode (for example, it can be a half-wave mode), as the auxiliary radiator part covering the first frequency band, and the current distribution direction is A1. In this way, the first antenna radiator 10 can work in the composite mode of the first frequency band, and the current distribution directions of the two modes are opposite, which can ensure the antenna performance of the first frequency band.

[0039] Optionally, the first feeding point 102 is arranged close to the first grounding point 101, that is, the distance from the first feeding point 102 to the first grounding point 101 is smaller than the distance from the first feeding point 102 to the second end of the first antenna radiator 10, so as to better excite the IFA mode of the first frequency band.

[0040] Optionally, the position of the first feeding point 102 on the first antenna radiator 10 is located on the second side of the electronic device. As an implementation, a portion of the radiator on the first antenna radiator 10 located on the first side of the electronic device and a portion of the radiator on the first antenna radiator 10 located on the second side of the electronic device are arranged at a preset angle (specifically determined based on the shape of the electronic device, such as 90 degrees), that is, the bending portion on the first antenna radiator 10 can be 90 degrees (here the shape of the bending portion can be a right angle shape, or it can also be an arc shape). Optionally, the first grounding point 101 can be set at the bending portion on the first antenna radiator 10 to ensure that the first feeding point 102 can be set on the portion of the radiator on the first antenna radiator 10 located on the second side of the electronic device to avoid occupying the space on the first side of the electronic device.

[0041] Optionally, the electronic device further includes: a metal ground 14 ; wherein the first grounding point 101 is connected to the metal ground 14 via a first capacitor 15 .

[0042] For example, the metal ground 14 can be a mainboard in an electronic device and a large piece of metal connected thereto. The metal ground 14 forms an induced current with the antenna radiator and can be used as a reference ground for the antenna.

[0043] In this embodiment, the first grounding point 101 is connected to the metal ground 14 via the first capacitor 15, that is, part of the radiator from the first grounding point 101 to the first end of the first antenna radiator 10 can be formed as a suspended metal branch (or called a suspended radiator), which can be used for specific absorption rate (SAR) detection. SAR refers to the electromagnetic radiation energy absorbed by a unit mass of a substance per unit time.

[0044] Specifically, a SAR sensor 103 is provided on the first antenna radiator 10; wherein, the distance from the connection position of the SAR sensor 103 and the first antenna radiator 10 to the first end is less than the distance from the first grounding point 101 to the first end. That is, the SAR sensor 103 is provided on the suspended metal branch (or called the suspended radiator) on the first antenna radiator 10 for SAR value detection.

[0045] Optionally, the electronic device further includes: a first feed source 17, wherein the first feed point 102 is connected to the first feed source 17. For example, the first feed source 17 may be disposed on a mainboard or other circuit board of the electronic device, but the embodiment of the present application is not limited thereto.

[0046] Optionally, the first frequency band is a GPS frequency band. For example, the GPS frequency band includes but is not limited to: GPS L1 frequency band, GPS L5 frequency band, etc. Optionally, the first frequency band may also be a WIFI frequency band, etc., and the embodiment of the present application is not limited thereto.

[0047] Optionally, continue to see Figure 4 The electronic device also includes: a second antenna radiator 13; wherein the second antenna radiator 13 is arranged along the first side of the electronic device, a coupling gap 16 is provided between the first antenna radiator 10 and the second antenna radiator 13, and the first insulating medium 11 covers the second antenna radiator 13.

[0048] The second antenna radiator 13 and the third portion of the first antenna radiator 10 are used to cover a second frequency band; wherein the third portion is the radiator from the first ground point 101 on the first antenna radiator 10 to the coupling interval 16 .

[0049] For example, the coupling interval 16 between the first antenna radiator 10 and the second antenna radiator 13 may mean that the first part of the first antenna radiator 10 and the second antenna radiator 13 have a coupling interval 16, or the first end of the first antenna radiator 10 and the first end of the second antenna radiator 13 have a coupling interval 16. That is, the first antenna radiator 10 and the second antenna radiator 13 are not in contact with each other and can interact through a spatial electromagnetic field at a relatively close distance.

[0050] Optionally, the coupling interval 16 may also be a break on a metal frame (or metal shell, or metal frame) of the electronic device. For example, a break is provided on a metal frame (or metal shell, or metal frame) of the electronic device, and a first antenna radiator 10 and a second antenna radiator 13 are formed on both sides of the break. By setting the physical width of the break, the break serves as a coupling interval 16 between the first antenna radiator 10 and the second antenna radiator 13. Optionally, a sound cavity may be provided at the position of the break (i.e., the coupling interval 16) on the electronic device.

[0051] Optionally, the second antenna radiator 13 serves as a carrier of radiated electromagnetic wave energy and cooperates with the third part of the first antenna radiator 10 to cover the second frequency band.

[0052] Optionally, a second grounding point 131 and a second feeding point 132 are provided on the second antenna radiator 13 , and the distance from the second grounding point 131 to the coupling interval 16 is greater than the distance from the second feeding point 132 to the coupling interval 16 .

[0053] Optionally, the second grounding point 131 may be disposed at the second end of the second antenna radiator 13; the second grounding point 131 is connected to the metal ground 14. The first end and the second end of the second antenna radiator 13 are disposed opposite to each other.

[0054] Optionally, the electronic device may further include a second feed source 18, and the second feed point 132 is connected to the second feed source 18. For example, the second feed source 18 may be disposed on a mainboard or other circuit board of the electronic device, but the embodiment of the present application is not limited thereto.

[0055] In this embodiment, a second feeding point 132 is provided on the second antenna radiator 13 for connecting the second feed source 18, that is, the second antenna radiator 13 can be used as the main radiator part covering the second frequency band, and the third part of the first antenna radiator 10 (that is, the part of the radiator between the coupling interval 16 and the first grounding point 101) can be used as the auxiliary radiator part covering the second frequency band, that is, energy is obtained by coupling from the second antenna radiator 13. In this way, the whole composed of the second antenna radiator 13 and the third part of the first antenna radiator 10 works in a half-wave mode to achieve coverage of the second frequency band. And because the first grounding point 101 on the first antenna radiator 10 is grounded through the first capacitor 15, the influence of the first frequency band operation on the performance of the second frequency band can be reduced. And the first insulating medium 11 is arranged to cover the second antenna radiator 13. In this way, since the first insulating medium 11 with a low dielectric constant is closer to the air wave impedance, it is more conducive to the radiation of electromagnetic waves in the second frequency band from the medium into the air, thereby meeting the efficiency of the second frequency band on the first side of the electronic device (for example, the first side is located at the top of the electronic device, which can meet the upper hemisphere efficiency of the second frequency band).

[0056] Optionally, the second frequency band is a medium to high frequency band. Of course, the second frequency band can also be other frequency bands that need to meet the upper hemisphere efficiency, or other frequency bands set on the top side of the electronic device, etc., and the embodiments of the present application are not limited thereto.

[0057] by Figure 4 For example, the electronic device shown in Figure 5 As shown, when the dielectric constants of the first insulating medium 11 and the second insulating medium 12 are the same, for example, both are 3, the antenna radiation pattern is biased toward the side (for example: Figure 5 When the dielectric constant of the first insulating medium 11 is adjusted to 4 and the dielectric constant of the second insulating medium 12 remains unchanged, the antenna radiation pattern is at the top of the electronic device (for example: Figure 5When the dielectric constant of the first insulating medium 11 is adjusted to 6 and the dielectric constant of the second insulating medium 12 is adjusted to 2, the top of the electronic device of the antenna radiation pattern is further strengthened, the bottom is greatly shrunk, and the radiation efficiency of the upper hemisphere is increased to 75.7%.

[0058] Optionally, the electronic device further includes: a third antenna radiator 20, and the third antenna radiator 20 can be grounded with the second antenna radiator 13. The third antenna radiator 20 is also provided with a third grounding point 201 and a third feeding point 202, and the distance from the third grounding point 201 to the second antenna radiator 13 is less than the distance from the third feeding point 202 to the second antenna radiator 13. The third antenna radiator 20 can be used to cover a third frequency band, for example, the third frequency band can be an NFC frequency band, or the third frequency band can also be other frequency bands that need to meet the upper hemisphere efficiency, or other frequency bands set on the top side of the electronic device, etc., and the embodiments of the present application are not limited thereto.

[0059] Optionally, the third grounding point 201 is connected to the metal ground 14 via a second capacitor 24. The third feeding point 202 is connected to a third feed source 22, for example, the third feed source 22 may be disposed on a mainboard or other circuit board of the electronic device, but the present application is not limited thereto.

[0060] Optionally, the electronic device further includes: a fourth antenna radiator 21, and a coupling interval is provided between the fourth antenna radiator 21 and the third antenna radiator 20. A fourth grounding point 211 and a fourth feeding point 212 are provided on the fourth antenna radiator 21, and the distance from the fourth grounding point 211 to the coupling interval is greater than the distance from the fourth feeding point 212 to the coupling interval. The fourth antenna radiator 21 can be used to cover the fourth frequency band and the fifth frequency band, for example, the fourth frequency band can be a WIFI frequency band, and the fifth frequency band can be an n78 frequency band, or the fourth frequency band and the fifth frequency band can also be other frequency bands that need to meet the upper hemisphere efficiency, or other frequency bands set on the top side of the electronic device, etc., and the embodiments of the present application are not limited thereto.

[0061] Optionally, the fourth grounding point 211 is connected to the metal ground 14. The fourth feeding point 212 is connected to the fourth feed source 23. For example, the fourth feed source 23 may be arranged on a mainboard or other circuit board of the electronic device, but the embodiment of the present application is not limited thereto.

[0062] Alternatively, if Figure 6 As shown, the first insulating medium 11 and the second insulating medium 12 are both made of a third insulating material; wherein the first insulating medium 11 is provided with a plurality of holes 112 .

[0063] For example, an insulating medium can be prepared on the surface of the first antenna radiator 10 using a third insulating material based on a process such as injection molding, filling, or spraying, and then the insulating medium portion covering the first portion of the surface of the first antenna radiator 10 is punched, that is, holes 112 are formed on the insulating medium portion covering the first portion of the surface of the first antenna radiator 10, so as to obtain the first insulating medium 11 covering the first portion of the surface of the first antenna radiator 10, and the insulating medium covering the second portion of the surface of the first antenna radiator 10 is referred to as the second insulating medium 12.

[0064] In this way, although the first insulating medium 11 and the second insulating medium 12 are both prepared using the same third insulating material (that is, the dielectric constants of the insulating materials used are the same), since a plurality of holes 112 are provided on the first insulating medium 11, the equivalent dielectric constant of the first insulating medium 11 can be reduced, that is, the dielectric constant of the first insulating medium 11 is smaller than the dielectric constant of the second insulating medium 12.

[0065] Optionally, the size and shape of the holes specifically opened on the first insulating medium 11 can be adjusted according to the debugging results. For example, the size and shape of the holes can be adjusted through a debugging test so that the dielectric constant of the first insulating medium 11 is smaller than the dielectric constant of the second insulating medium 12, so as to ensure the efficiency of the first frequency band covered by the first antenna radiator 10 on the first side of the electronic device, and reduce the processing difficulty compared to coating the first antenna radiator 10 with an insulating medium of different dielectric constants.

[0066] In this embodiment, the specific structure of the first antenna radiator 10 can refer to the above embodiment. Figure 6 The electronic device shown may further include a second antenna radiator 13, a third antenna radiator 20, a fourth antenna radiator 21, etc. The specific structure may also refer to the above embodiments, and will not be described again here to avoid repetition.

[0067] Alternatively, if Figure 7 As shown, the first insulating medium 11 includes: a first main dielectric portion 110 and a first coating 111, the first main dielectric portion 110 covers a first portion of the first antenna radiator 10, and the first coating 111 covers the surface of the first main dielectric portion 110;

[0068] The second insulating medium 12 includes: a second main dielectric portion 120 and a second coating 121, wherein the second main dielectric portion 120 covers the second portion of the first antenna radiator 10, and the second coating 121 covers the surface of the second main dielectric portion 120;

[0069] The dielectric constants of the first main dielectric portion 110 and the second main dielectric portion 120 are the same, or the dielectric constant of the first main dielectric portion 110 is smaller than the dielectric constant of the second main dielectric portion 120 ; and the dielectric constant of the first coating 111 is smaller than the dielectric constant of the second coating 121 .

[0070] For example, the first main dielectric portion 110 and the second main dielectric portion 120 are both made of a fourth insulating material, and the dielectric constant of the first coating 111 is smaller than the dielectric constant of the second coating 121 .

[0071] For example, the fourth insulating material can be used to prepare an insulating medium on the surface of the first antenna radiator 10 based on injection molding, filling or spraying processes, wherein the insulating medium portion coated on the first part of the surface of the first antenna radiator 10 is called the first main body dielectric portion 110, and the insulating medium portion coated on the second part of the surface of the first antenna radiator 10 is called the second main body dielectric portion 120, that is, the first main body dielectric portion 110 and the second main body dielectric portion 120 are prepared by the same fourth insulating material (that is, the dielectric constant of the insulating material used is the same), which can reduce the difficulty of processing. Then, a paint with a low dielectric constant is sprayed on the surface of the first main body dielectric portion 110 to obtain a first coating 111, and a paint with a high dielectric constant is sprayed on the surface of the second main body dielectric portion 120 to obtain a second coating 121, that is, the dielectric constant of the first coating 111 is less than the dielectric constant of the second coating 121, so that the dielectric constant of the first insulating medium 11 is less than the dielectric constant of the second insulating medium 12, thereby ensuring the efficiency of the first frequency band covered by the first antenna radiator 10 on the first side of the electronic device.

[0072] In this embodiment, the specific structure of the first antenna radiator 10 can refer to the above embodiment. Figure 7 The electronic device shown may further include a second antenna radiator 13, a third antenna radiator 20, a fourth antenna radiator 21, etc. The specific structure may also refer to the above embodiments, and will not be described again here to avoid repetition.
