[0001] The present application belongs to the field of communication technology, and specifically relates to an antenna module and an electronic device. Background Art

[0002] In the related art, an end-fire antenna can be provided on an electronic device, such as a satellite antenna module. With the development of communication technology, users have higher and higher demands on the communication performance of electronic devices. In order to meet the needs of users, it is usually necessary to improve the gain of the antenna module.

[0003] In the related art, the antenna gain is usually improved by optimizing the polarization direction of the antenna. However, with the trend of electronic devices becoming increasingly lighter and thinner, it is difficult to set an antenna module with a good polarization direction on the thin frame of an electronic device.

[0009] Wherein, when the feed source is working, the coupling effect between the second metal part and the first radiator stimulates the radiation direction of the first radiator to be toward a first direction, and stimulates the first metal part to form a traveling standing wave mode consistent with the first direction on the floor, and the first direction is the direction from the second side edge to the first side edge.

[0020] The following will be combined with the drawings in the embodiments of the present application to clearly describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application belong to the scope of protection of this application.

[0021] The terms "first", "second", etc. in the specification and claims of this application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0022] In order to facilitate understanding of the antenna module and electronic device provided in the embodiments of the present application, the technology related to the present application is first explained.

[0023] The antenna module provided in the embodiment of the present application can be any end-fire antenna module, such as a satellite antenna module, a 4G end-fire antenna module, a 5G end-fire antenna module, etc., and is not specifically limited here.

[0024] Among them, the end-fire antenna module may mean that the radiation direction of the antenna module is parallel to the plane of the floor, and the radiation source is located at the end surface of the floor, so that the antenna radiation signal can be radiated outward from the end surface of the floor in a direction parallel to the floor.

[0025] It should be noted that, for the sake of convenience, the embodiments of the present application are generally described by taking a satellite antenna module as an example, which does not constitute a specific limitation herein.

[0026] It is worth mentioning that with the development of mobile communications, satellite communication functions are becoming an indispensable part of electronic devices such as smartphones. Traditional mobile communications rely on ground base stations, but in extreme environments or remote areas, signal coverage is limited. At this time, the technology of direct satellite communication between electronic devices to achieve global communications has emerged. This technology can achieve seamless information exchange on a global scale and truly realize ubiquitous communication.

[0027] However, in direct communication from an electronic device to a satellite, the Faraday rotation effect in the ionosphere may cause polarization mismatch, resulting in a gain loss of about 3 dB, resulting in low transmission stability of the signal from the electronic device to the satellite. In the embodiment of the present application, a traveling standing wave consistent with the end-fire direction can be constructed on the floor using the first metal member to enhance the gain in the end-fire direction, thereby overcoming the signal attenuation caused by environmental factors and improving the transmission stability of the signal from the electronic device to the satellite.

[0028] It is worth noting that in the embodiment of the present application, a traveling standing wave in the same direction as the end-fire direction is constructed on the floor by using a first metal part to enhance the gain in the end-fire direction; this method needs to be distinguished from the related art, in which the floor is used as a reflector to reflect the radiation signal of the end-fire antenna to enhance the gain in the end-fire direction. Among them, the use of a first metal part to construct a traveling standing wave in the same direction as the end-fire direction on the floor enhances the gain of the end-fire antenna significantly more than the use of the floor as a reflector to reflect the radiation signal of the end-fire antenna.

[0029] The antenna module and electronic device provided in the embodiments of the present application are described in detail below through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0030] See also Figure 1 , the antenna module provided in the embodiment of the present application includes: a feed source 10, a floor 20, a first radiator 30, a first metal part 40 and a second metal part 50;

[0031] The first radiator 30 is spaced apart from the floor 20, and a first gap 211 is formed between the first radiator 30 and the first side 21 of the floor 20. The first metal member 40 is electrically connected to a first area A of the floor 20. The first area A is close to the second side 22 of the floor 20. The first side 21 and the second side 22 are two opposite sides of the floor 20.

[0032] The second metal member 50 is located on a side of the first radiator 30 close to the floor 20 , and the second metal member 50 is coupled to the first radiator 30 through the first gap 211 ;

[0033] The feed source 10 is electrically connected to the second metal member 50 and the first metal member 40 respectively;

[0034] In which, when the feed source 10 is working, the coupling between the second metal part 50 and the first radiator 30 excites the radiation direction of the first radiator 30 toward the first direction X, and excites the first metal part 40 to form a traveling standing wave mode consistent with the first direction X on the floor 20, wherein the first direction X is the direction from the second side 22 to the first side 21.

[0035] In some implementations, the antenna module provided in the embodiments of the present application may have an antenna type of any type, such as a slot antenna, a loop antenna, etc., which is not specifically limited herein.

[0036] In some implementations, the polarization form of the antenna module provided in the embodiments of the present application may be horizontal polarization or vertical polarization, which is not specifically limited herein.

[0037] In some embodiments, the first radiator 30 may be located on the top of the floor 20 , that is, the first side edge 21 is the top edge of the floor 20 .

[0038] Of course, the first radiator 30 may also be located on other sides of the floor 20, such as the left side, the right side or the bottom side. For the sake of convenience of explanation, in the embodiment of the present application, the first radiator 30 may be located on the top of the floor 20 and the first metal part 40 is located at the bottom of the floor 20 as an example, which is not constituted as a specific limitation here.

[0039] In some embodiments, the first direction X may be referred to as an end-fire direction of the antenna module, which is parallel to the plane where the floor 20 is located, and radiates outward from the first radiator 30 toward a direction away from the second side 22 .

[0040] In some embodiments, the first radiator 30 is spaced apart from the floor 20 to form a suspended metal structure, thereby reducing the electrical connection between the first radiator 30 and the floor 20 or other second metal parts, thereby reducing the interference of the coupling between the first radiator 30 and the second metal part 50.

[0041] In some embodiments, the second metal member 50 may be composed of a segment of a feed line that is parallel to the first radiator 30 , and the feed line is used to achieve electrical connection between the second metal member 50 and the feed source 10 .

[0042] In other embodiments, the second metal member 50 may be composed of a structure such as a metal plate parallel to the first radiator 30 . In this case, the metal plate may be electrically connected to the feed source 10 via an additional feed line.

[0043] In some embodiments, the feed source 10 may include a feeding network, which includes two output ports, wherein one output port is electrically connected to the second metal member 50 to feed the second metal member 50, thereby coupling an end-fire radiation mode on the first radiator 30; the other output port is electrically connected to the first metal member 40 to feed the first metal member 40, thereby exciting a traveling standing wave current on the floor 20 electrically connected to the first metal member 40, and the traveling standing wave current forms a traveling standing wave radiation mode toward the first direction X, which can enhance the end-fire radiation mode toward the first direction X on the first radiator 30.

[0044] It should be noted that the excitation current on the first radiator 30 needs to be consistent in phase with the traveling standing wave current on the floor 20, so that the gain enhancement effect of the traveling standing wave radiation mode on the end-fire radiation mode can be improved.

[0045] The phase consistency may be that the first radiator 30 and the floor 20 simultaneously generate radiation modes toward the first direction X, or that the phase difference between the radiation mode toward the first direction X generated on the first radiator 30 and the radiation mode toward the first direction X generated on the floor 20 is small, such as less than or equal to 10°.

[0046] In some embodiments, in order to achieve phase consistency between the excitation current on the first radiator 30 and the traveling standing wave current on the floor 20, the second metal part 50 and the first metal part 40 can be electrically connected to the same feed source 10, and the shape and size of the first metal part 40 can be designed so that the resonant frequency of the first metal part 40 is consistent with the resonant frequency of the first radiator 30.

[0047] In other embodiments, Figure 2 As shown, in order to achieve phase consistency between the excitation current on the first radiator 30 and the traveling standing wave current on the floor 20, the second metal part 50 and the first metal part 40 can be electrically connected to the same feed source 10 through a power divider 60, and a phase modulator 70 can be provided to be electrically connected to at least one of the second metal part 50 and the first metal part 40, so as to adjust the resonant frequency of the first metal part 40 to be consistent with the resonant frequency of the first radiator 30 through the phase modulator 70.

[0048] In some other embodiments, in order to achieve phase consistency between the excitation current on the first radiator 30 and the traveling standing wave current on the floor 20, two feed sources 10 electrically connected to the second metal part 50 and the first metal part 40, respectively, can be provided, and by controlling the phase or frequency of the excitation signals output by the two feed sources 10, the resonant frequency of the first metal part 40 can be adjusted to be consistent with the resonant frequency of the first radiator 30.

[0049] As an optional embodiment, the floor 20 further includes a third side edge 23 adjacent to the first side edge 21 and the second side edge 22;

[0050] The distance between the first area A and the second side 22 is less than or equal to 30% of the total length of the third side 23 .

[0051] For example: Figure 1 As shown, the first side 21 is the top edge of the floor 20, the second side 22 is the bottom edge of the floor 20, the third side 23 is the left edge of the floor 20, and the first area A represents the area on the floor 20 close to the second side 22, and the distance between the projection position of the first area A on the third side 23 and the second side 22 is less than or equal to 30% of the total length of the third side 23.

[0052] In this embodiment, by setting the first metal member 40 in the bottom area of ​​the floor 20 away from the first radiator 30, the direction of the traveling standing wave formed by the first metal member 40 on the floor 20 can be more consistent with the first direction X, thereby improving the gain enhancement effect of the traveling standing wave mode on the floor 20 on the end-fire mode of the first radiator 30.

[0053] In some embodiments, Figure 2As shown, the first metal member 40 may be a metal block, which is located at the lower left corner of the floor 20 .

[0054] In other embodiments, Figure 3 As shown, the first metal member 40 may be a metal branch, and one end of the metal branch away from the electrical connection with the feed source 10 is open-circuited.

[0055] As an optional implementation manner, the first metal member 40 includes a metal branch, and an end of the metal branch facing the first radiator 30 is spaced apart from the floor 20 .

[0056] For example: the first radiator 30 and the first metal part 40 can be two radiating branches on the metal frame of the electronic device, wherein the metal frame of the electronic device is arranged around the floor 20. At this time, the radiating branch serving as the first metal part 40 can be a metal frame located in the lower left corner area of ​​the floor 20, and a break 41 is provided at one end of the metal frame serving as the first metal part 40 facing the top of the electronic device.

[0057] It should be noted that in the embodiment of the present application, the first metal member 40 is located at the lower left corner of the floor 20 for illustration. In other embodiments, the first metal member 40 may also be located at the lower right corner of the floor 20, which is not specifically limited herein.

[0058] In addition, in addition to the above-mentioned metal blocks or metal branches, the first metal member 40 may also adopt other structures, which are not specifically limited here.

[0059] Through the above implementation manner, the first metal part 40 can be flexibly set to a metal block or a metal branch according to the actual deployment scenario of the antenna module. For example, when applied to an electronic device with a metal frame, the first metal part 40 can be set to a metal branch of a reused metal frame. When applied to an electronic device without a metal frame, or when there is no extra space on the metal frame as the first metal part 40, the first metal part 40 can be set to a metal block housed in a housing of the electronic device.

[0060] In some embodiments, according to different operating frequency bands of the feed source 10 , the size and shape of the first metal member 40 can be adaptively adjusted so that the resonant frequency of the first metal member 40 avoids the operating frequency band of the feed source 10 .

[0061] For example, taking the antenna module as a Tiantong satellite antenna, at this time, the working frequency band of the first radiator 30 is 2100 MHz-2400 MHz; the electrical length of the first metal part 40 is 2 mm to 15 mm.

[0062] In this way, the first metal part 40 does not resonate in the working frequency band of the feed source 10, reducing the radiation generated by the first metal part 40. The first metal part 40 is mainly used to excite the traveling standing wave mode of the floor 20. The radiation direction of the traveling standing wave mode of the floor 20 is toward the first direction, thereby enhancing the first radiator 30.

[0063] As an optional implementation, Figure 4 or Figure 5 As shown, the floor 20 further includes a fourth side edge 24, and the fourth side edge 24 and the third side edge 23 are two opposite sides of the floor 20;

[0064] The floor 20 is provided with a first choke slot 201 and a second choke slot 202. The opening end of the first choke slot 201 is arranged through the third side 23, and the opening end of the second choke slot 202 is arranged through the fourth side 24.

[0065] The length of the first choke slot 201 and the second choke slot 202 is ¼ wavelength of the operating frequency of the first radiator 30 .

[0066] In some embodiments, the first choke slot 201 and the second choke slot 202 are L-shaped structures, such as Figure 4 As shown, taking the first choke slot 201 as an example, the first choke slot 201 includes two segments which are perpendicular to each other and connected end to end, one of which is parallel to the first radiator 30, and one end of the segment passes through the third side 23, and the other segment of the first choke slot 201 is perpendicular to the first radiator 30, and the other segment extends in a direction away from the first radiator 30.

[0067] In some embodiments, taking the antenna module as a satellite antenna as an example, at this time, the length of the first choke slot 201 and the second choke slot 202 can be 15 mm. At this time, the first choke slot 201 and the second choke slot 202 can have a good blocking effect on the radiation of the first radiator 30 in the opposite direction of the first direction X, thereby further improving the radiation gain in the first direction X.

[0068] In some embodiments, the distance between the open end of the first choke slot 201 and the first side 21, as well as the distance between the open end of the second choke slot 202 and the first side 21, can be between 20 mm and 60 mm. For example, taking the antenna module as a satellite antenna, the distance between the open end of the first choke slot 201 and the first side 21, as well as the distance between the open end of the second choke slot 202 and the first side 21 can be equal to 30 mm. At this time, the first choke slot 201 and the second choke slot 202 have a better blocking effect on the radiation of the first radiator 30 in the opposite direction of the first direction X.

[0069] It is worth mentioning that when the first radiator 30 located on one side of the floor 20 radiates, a part of the floor 20, especially the two side edges of the floor 20 corresponding to the two ends of the first radiator 30, will have a traveling standing wave radiation mode in the opposite direction to the first direction X. In this embodiment, by respectively providing choke slots at the positions of the floor 20 corresponding to the two ends of the first radiator 30, the choke slots can be used to block the traveling standing wave radiation mode of the floor 20 in the opposite direction to the first direction X, which can further improve the gain of the antenna module in the first direction X.

[0070] As an optional implementation, Figure 2 , Figure 3 , Figure 4 or Figure 5 As shown, the antenna module also includes:

[0071] A power divider 60, the power divider 60 comprises an input terminal I, a first output terminal O1 and a second output terminal O2;

[0072] The feed source 10 is electrically connected to the input terminal I of the power divider 60 , the first output terminal O1 of the power divider 60 is electrically connected to the second metal member 50 , and the second output terminal O2 of the power divider 60 is electrically connected to the first metal member 40 .

[0073] The power divider 60 in the embodiment of the present application and any power divider in the related art may adopt the same structure and working principle, which is not specifically limited here.

[0074] In this embodiment, the second metal member 50 and the first metal member 40 use the same feed source 10 for feeding, which can simplify the structure of the antenna module and reduce the cost of the antenna module.

[0075] It is worth noting that it is necessary to make the phase of the end-fire mode coupled by the second metal part 50 on the first radiator 30 consistent with the traveling standing wave mode excited by the first metal part 40 on the floor 20. In this embodiment, the phase of the traveling standing wave mode excited on the floor 20 can be adjusted by adding a matching network electrically connected to the first metal part 40, a phase modulator, etc.; and / or, the phase of the end-fire mode coupled on the first radiator 30 can be adjusted by adding a matching network electrically connected to the second metal part 50, a phase modulator, etc.

[0076] For example: Figure 2 , Figure 3 , Figure 4 or Figure 5 As shown, the antenna module also includes:

[0077] a phase modulator 70 , the phase modulator 70 being electrically connected to at least one of the second metal member 50 and the first metal member 40 ;

[0078] The phase modulator 70 is used to adjust the phase of at least one of the second metal member 50 and the first metal member 40 so that the first radiation mode of the first radiator 30 along the first direction X is consistent with the phase of the second radiation mode of the first metal member 40 excited on the floor 20 along the first direction X.

[0079] In some embodiments, the phase modulator 70 can be implemented using a microstrip line. For example, taking the antenna module operating within a bandwidth of 2100MHz-2400MHz as an example, the phase modulator 70 can use a 50Ω microstrip line, and by designing the length of the microstrip line, a phase shift function of the excitation signal of at least one of the second metal component 50 and the first metal component 40 can be achieved, such as shifting the phase of the excitation signal of the first metal component 40 by 210°.

[0080] The phase modulator 70 in the embodiment of the present application and any phase modulator in the related art may adopt the same structure and working principle, which is not specifically limited here.

[0081] In this embodiment, by adjusting the phase of at least one of the second metal component 50 and the first metal component 40 through the phase modulator 70, the phase difference between the first radiation mode along the first direction X and the second radiation mode along the first direction X can be compensated, so that the phase of the first radiation mode is consistent with that of the second radiation mode. In this way, the second radiation mode can enhance the first radiation mode to the greatest extent.

[0082] As an optional implementation, the second metal member 50 includes a first feeder line, and the feed source 10 and the second metal member 50 are electrically connected to each other through the first feeder line;

[0083] The first feed line includes a first segment 51 and a second segment 52 . The first segment 51 is coupled to the first radiator 30 via the first gap 211 , and the second segment 52 is electrically connected to the first segment 51 and the feed source 10 .

[0084] In this embodiment, the segments of the feed line that are parallel to and spaced apart from the first radiator 30 can be reused to form the second metal member 50 , which can simplify the structure of the antenna module.

[0085] It should be noted that the antenna module provided in the embodiment of the present application also includes a second feed line 80 , which is used to electrically connect the feed source 10 with the first metal member 40 .

[0086] For example: Figure 2 As shown, the antenna module includes: a feed source 10, a floor 20, a first radiator 30, a first metal member 40, a first feed line, a power divider 60, a phase modulator 70 and a second feed line 80.

[0087] The first feeder includes a first segment 51 and a second segment 52, and the first segment serves as a first metal member 40. The feed source 10 is electrically connected to the input terminal I of the power divider 60, the first output terminal O1 of the power divider 60 is electrically connected to the first segment 51 of the first feeder through the second segment 52 of the first feeder, the second output terminal O2 of the power divider 60 is electrically connected to the first metal member 40 through the second feeder 80, the phase modulator 70 is arranged on the second segment 52 of the first feeder, the first radiator 30 and the first metal member 40 are distributed on both sides of the floor 20, and there is a first gap 211 between the first radiator 30 and the first side 21 of the floor 20, and the first segment 51 of the first feeder is coupled to the first radiator 30 through the first gap 211.

[0088] In this way, during the operation of the feed source 10, the feed signal is divided into two paths through the power divider 60. One path excites the end-fire mode of the first radiator 30 in the first direction X through the first feed line, and the other path excites the traveling standing wave mode of the floor 20 in the first direction X through the second feed line 80 and the second metal part 50. In this way, the end-fire mode of the first radiator 30 in the first direction X can be enhanced by the traveling standing wave mode of the floor 20 in the first direction X.

[0089] like Figure 6 An S-parameter curve diagram of the antenna module provided in an embodiment of the present application; Figure 7 The maximum gain curve of the antenna module provided in the embodiment of the present application at the top of the floor 20 within θ=0-30°, φ=0-360°. Gain curve diagram. Figure 6 It can be seen that the -6dB bandwidth of the antenna module provided in the embodiment of the present application can cover 2100MHz-2400MHz. Figure 7 It can be seen that Figure 2 The antenna module shown in the figure excites a traveling standing wave mode along a first direction on the floor 20 through a first metal member 40, and has a maximum gain of 6.9dBi within a bandwidth of 2100MHz-2400MHz. Compared with the related art in which the traveling standing wave mode of the floor 20 is not used to enhance the antenna gain, the maximum gain within the bandwidth of 2100MHz-2400MHz is increased by 2.7dBi.

[0090] In addition, if Figure 7 As shown, for the embodiments of the present application provided Figure 4 or Figure 5 The antenna module shown, on the basis of exciting a traveling standing wave mode along a first direction on the floor 20 through the first metal member 40, further adds choke slots, namely a first choke slot 201 and a second choke slot 202, the maximum gain of the antenna module in the range of 2100MHz-2400MHz can even reach 7.28dBi.

[0091] In an embodiment of the present application, the second metal part and the first metal part are fed respectively by a feed source, wherein the feeding signal to the second metal part can excite the second metal part so that the first radiator generates an end-fire signal from the second metal part to the first radiator based on the coupling between the second metal part and the first metal part, and the feeding signal to the first metal part can excite a traveling standing wave consistent with the end-fire direction of the first radiator on a floor electrically connected to the first metal part. In this way, the traveling standing wave on the floor can be used to enhance the radiation gain of the antenna module in the end-fire direction. The principle is simple, and the problem of high design difficulty in the solution of increasing the gain of the end-fire antenna can be solved.

[0092] The present application also provides an electronic device, which includes: Figures 1 to 5 Any type of antenna module provided in the illustrated embodiment.

[0093] In some embodiments, the electronic device may be a terminal or other device other than a terminal. For example, the electronic device may be a mobile phone, a tablet computer, a laptop computer, a PDA, a vehicle-mounted electronic device, a mobile Internet device (MID), an augmented reality (AR) / virtual reality (VR) device, a robot, a wearable device, an ultra-mobile personal computer (UMPC), a netbook or a personal digital assistant (PDA), etc. It may also be a server, a network attached storage (NAS), a personal computer (PC), a television (TV), a teller machine or a self-service machine, etc., which is not specifically limited in the embodiments of the present application.

[0094] In some embodiments, Figure 8 As shown, the floor 20 in the antenna module is the main floor of the electronic device, and the first radiator 30 is located at the top of the electronic device.

[0095] In this embodiment, if Figure 8 As shown, the antenna module can be used to construct an end-fire antenna facing the top of the electronic device, which is particularly suitable for a satellite antenna, wherein the electronic device is in a holding state for a satellite call, and the top of the electronic device is facing the sky. By placing the first radiator 30 at the top of the electronic device, the end-fire direction of the first radiator 30 can be facing the sky, which can improve the satellite communication performance.

[0096] In some embodiments, Figure 8 As shown, the electronic device also includes:

[0097] The first dielectric plate 90, the floor 20 is located on the first side of the first dielectric plate 90, such as Figure 8 The lower surface of the first dielectric plate 90 is shown in FIG. 1 , and the feed source 10, the first radiator 30, the first metal member 40 and the second metal member 50 are located on the second side of the first dielectric plate 90, as shown in FIG. Figure 8 The lower surface of the first dielectric plate 90 is shown in FIG. 1 , wherein the first side and the second side are opposite sides of the first dielectric plate 90 , and the dielectric constant of the first dielectric plate 90 is 3.55.

[0098] Optionally, the first radiator 30 , the first metal member 40 and the second metal member 50 may be directly attached to the second side surface of the first dielectric plate 90 , and the feed source 10 may be disposed on a main board located on the second side of the first dielectric plate 90 .

[0099] In some embodiments, the thickness of the first dielectric plate 90 can be adjusted according to the actual application scenario. For example, the greater the radiation intensity of the antenna module, the thicker the thickness of the first dielectric plate 90. For example, taking the antenna module as a satellite antenna as an example, the thickness of the first dielectric plate 90 can be 0.508 mm.

[0100] In this embodiment, by stacking a first dielectric plate 90 on the floor 20, and arranging electrical structures such as a feed source 10, a first radiator 30, a first metal part 40 and a second metal part 50 on the side of the first dielectric plate 90 facing away from the floor 20, the first dielectric plate 90 with a low dielectric constant can be used to reduce electromagnetic wave interference between these electrical structures and the floor 20.

[0101] In some embodiments, the electronic device further includes: a metal frame S1 and a second dielectric plate 100, the second dielectric plate 100 is disposed around the periphery of the first dielectric plate 90, and the metal frame S1 is disposed on the outer side of the second dielectric plate 100;

[0102] The first radiator 30 is disposed on the metal frame S1 , or the first radiator 30 and the first metal member 40 are disposed on the metal frame S1 .

[0103] In this embodiment, second dielectric plates perpendicular to the plane where the floor 20 is located may be further arranged around the floor 20, such as a first sub-dielectric plate 101 located at the first side 21 of the floor 20, a second sub-dielectric plate 102 located at the second side 22 of the floor 20, a third sub-dielectric plate 103 located at the third side 23 of the floor 20, and a fourth sub-dielectric plate 104 located at the fourth side 24 of the floor 20.

[0104] In some embodiments, the first sub-dielectric plate 101, the second sub-dielectric plate 102, the third sub-dielectric plate 103, and the fourth sub-dielectric plate 104 can reduce electromagnetic wave interference between the floor 20 and the metal edge S1 of the electronic device, or reduce electromagnetic wave interference between the floor 20 and the external environment where the electronic device is located.

[0105] In some embodiments, the dielectric constant of the second dielectric plate 100 may be set to be greater than the dielectric constant of the first dielectric plate 90, and / or the thickness of the second dielectric plate 100 may be set to be less than the thickness of the first dielectric plate 90. For example, the thickness of the first dielectric plate 90 may be 0.508 mm, and the dielectric constant may be 3.55; and the thickness of the first sub-dielectric plate 101, the second sub-dielectric plate 102, the third sub-dielectric plate 103, and the fourth sub-dielectric plate 104 may be 0.5 mm, and may be made of FR-4 material, wherein the dielectric constant of the FR-4 material relative to air is between 4.2 and 4.7.

[0106] In this way, the second dielectric board 100 around the floor 20 with a smaller electromagnetic wave interference intensity can be made of a relatively low-priced FR-4 dielectric board, which can reduce the cost of electronic equipment while ensuring the anti-electromagnetic wave interference performance of the floor 20 .

[0107] In some embodiments, Figure 2 As shown, the first radiator 30 is disposed on the metal frame S1 , and the first metal member 40 can be received in the metal frame S1 .

[0108] In some embodiments, Figure 3 As shown, the first radiator 30 and the first metal member 40 are respectively disposed at the upper and lower ends of the metal frame S1.

[0109] In this embodiment, part of the metal frame S1 of the electronic device can be reused to construct the first radiator 30, or part of the metal frame S1 of the electronic device can be reused to construct the first radiator 30 and the first metal member 40, which can simplify the structure of the electronic device.
