DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments of the present application. Those skilled in the art will know that with the development of technology and the emergence of new scenarios, the technical solutions provided in the embodiments of the present application are also applicable to similar technical problems.

[0045] As described in the background, antenna efficiency in electronic devices is low due to limited internal mounting space. To improve antenna efficiency, a common design approach is to position the antenna near a first side of the electronic device, with a spaced area between the display assembly and the first side to allow the antenna to radiate signals into space.

[0046] Although the above solution can improve the antenna efficiency to a certain extent, since the antenna mainly radiates the antenna signal through the reserved spacing area between the display component and the first side, the antenna signal radiated to the other side away from the first side will be absorbed by the metal components inside the electronic device. This part of the antenna signal cannot be radiated from the spacing area to the space, thereby reducing the antenna efficiency of the target antenna.

[0047] In order to solve the above problems, an embodiment of the present application provides an electronic device, which includes:

[0048] Display components,

[0049] a first side edge, wherein the display assembly and the first side edge form a spacing area;

[0050] The target antenna is disposed on the back of the display assembly and has a first spacing from the first side;

[0051] The reflective component is located on a side of the target antenna away from the first side, and is used to reflect at least part of the antenna signal emitted by the target antenna to the reflective component toward the first side so as to radiate into space through the spacing area.

[0052] Based on the above description, it can be seen that in the electronic device provided in the embodiment of the present application, a reflective component capable of reflecting antenna signals is provided on the side of the target antenna away from the first side. The antenna signal transmitted by the target antenna to the reflective component can be reflected toward the first side through the reflective component, and the antenna signal transmitted by the target antenna away from the first side can be reflected toward the first side, so that this part of the antenna signal can also be radiated into the space in the interval area, thereby avoiding this part of the antenna signal being absorbed by the electronic components of the electronic device inside the electronic device, thereby improving the antenna efficiency of the target antenna.

[0053] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0054] refer to Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the layout of a target antenna and a reflective component in an electronic device provided in an embodiment of the present application. Figure 2 for Figure 1 A cross-sectional view of the electronic device shown at the target antenna location. Figure 2 The section shown is perpendicular to the thickness direction of the electronic device ( Figure 2 vertical direction in the ).

[0055] like Figure 1 and Figure 2As shown, the electronic device includes: a display component 100; a first side 101, wherein the display component 100 and the first side 101 form a spacing area 106; a target antenna 102, wherein the target antenna 102 is disposed on the back of the display component 100 and has a first spacing 105 with the first side 101; and a reflective component 103, wherein the reflective component 103 is located on the side of the target antenna 102 away from the first side 101 and is configured to reflect at least part of the antenna signal transmitted by the target antenna 102 to the reflective component 103 toward the direction of the first side 101 so as to radiate into space through the spacing area 106. In order to clearly illustrate the layout of the target antenna 102 and the reflective component 103 inside the electronic device, Figure 1 The display assembly 100 is not shown.

[0056] The first side 101 is a metal frame on one side of the electronic device. A first distance is defined between the display assembly 100 and the first side 101, forming a spacing region 106. A second distance is defined between the target antenna 102 and the first side 101, forming a first spacing region 105. To allow more antenna signals to radiate from the spacing region to the display side, the second distance can be set to be no less than the first distance.

[0057] like Figure 1 As shown, the reflective component 103 includes a plurality of periodically arranged resonant units 104, the rejection frequency of which is adapted to the operating frequency of the target antenna 102 to reflect the antenna signal. Optionally, the plurality of resonant units 104 on the same side of the target antenna 102 can be arranged in an array.

[0058] The array of resonant units 104 is constructed as a frequency selective surface (FSS). The reflective component 103 includes a frequency selective surface. By adjusting the design parameters of each resonant unit, the resonant frequency of the resonant unit can be adapted to the frequency of the antenna signal. The resonant unit can generate total reflection through the oscillation of the induced current, so that almost all of the energy of the incident antenna signal is reflected back, forming a band-stop characteristic.

[0059] In the electronic device provided in the embodiment of the present application, a reflective component 103 capable of reflecting antenna signals is provided on the side of the target antenna 102 away from the first side 101. The antenna signal transmitted by the target antenna 102 to the reflective component 103 can be reflected toward the first side 101 through the reflective component 103, and the antenna signal transmitted by the target antenna 102 away from the first side 101 can be reflected toward the first side 101, so that this part of the antenna signal can also be radiated into space in the spacing area 106, thereby avoiding this part of the antenna signal being absorbed by the electronic components of the electronic device inside the electronic device, thereby improving the antenna efficiency of the target antenna 102.

[0060] Optionally, the electronic device includes a metal housing, which includes a metal bottom shell opposite to the display assembly 100 and a metal frame surrounding the periphery of the display assembly 100. The target antenna 102 and the reflective assembly 103 are located in the accommodation space formed between the metal bottom shell and the display assembly 100.

[0061] First side 101 is a metal frame surrounding the perimeter of display assembly 100. Spacer region 106 forms the black border of display assembly 100, serving as the radiation area for target antenna 102. Spacer region 106 includes an insulating shielding member, which can be a layer of black ink. This shielding member forms the border area of ​​display assembly 100 near first side 101. This shielding member not only insulates the antenna signal from spacer region 106 toward the display side, but also prevents visibility of the electronic device's internal components.

[0062] In one embodiment, Figure 2 As shown, target antenna 102 comprises a metal radiator with a cavity 110. The metal radiator has an open window on at least one side proximal to the black border region. A reflective component 103 is also positioned opposite the metal radiator on at least the other side, facing away from the black border region. In this embodiment, target antenna 102 is a cavity antenna. The open window allows the antenna signal energy to be primarily radiated toward first side 101, allowing more energy to radiate through the spacer region toward the display side without reflection from reflective component 103.

[0063] Alternatively, as Figure 2 As shown, the metal radiator includes a top metal layer 107, a middle metal layer 108, and a bottom metal layer 109. The middle metal layer 108 includes a first metal portion 111 and a second metal portion 112. The first metal portion 111 is integrally connected to the top metal layer 107, and the second metal portion 112 is integrally connected to the bottom metal layer 109. A gap is formed between the first metal portion 111 and the second metal portion 112, and a feeding point 113 is connected to the gap.

[0064] refer to Figure 3 , Figure 3 A structural schematic diagram of a cavity antenna provided in an embodiment of the present application, in which the cavity antenna includes a special-shaped metal part 114 bent to form a cavity 110, and the middle area of ​​the metal part 114 has a recessed portion, and the recessed portion has a gap, and the gap is connected to the feeding point 113.

[0065] When the target antenna 102 is a cavity antenna, the structure of the cavity antenna can be designed according to the communication frequency band requirements of the electronic device and the antenna installation space reserved inside the electronic device. The embodiment of the present application does not limit the structure of the cavity antenna.

[0066] Using the cavity antenna as the target antenna 102, not only can the radiation direction be set in a targeted manner through the open window in the cavity antenna to improve the antenna efficiency, but the antenna signal radiated by the target antenna away from the first side 101 can also be further reflected through the reflection component 103 to further improve the antenna efficiency.

[0067] It should be noted that the target antenna 102 is not limited to a cavity antenna, and other types of antennas may also be used. For example, the target antenna 102 may also be a PIFA antenna (planar inverted-F antenna), a monopole antenna, an FPC antenna, an LDS antenna, a slot antenna, or a reconfigurable antenna.

[0068] refer to Figure 4 , Figure 4 This is a cross-sectional view of a reflective component provided in an embodiment of the present application, wherein the cross-sectional view is perpendicular to the thickness direction of the electronic device ( Figure 4 The reflective assembly 103 includes a plurality of patterned metal layers 115 stacked in sequence along a first direction, with an insulating dielectric layer 116 disposed between adjacent patterned metal layers 115. The first direction is perpendicular to the display assembly 100, i.e., the first direction is parallel to the thickness of the electronic device. The dielectric constant of the dielectric layer 116 is not less than 6.

[0069] The dielectric constant of dielectric layer 116 is not less than 6. Dielectric layer 116 is a high dielectric constant material with a large dielectric constant. Using a multi-layer patterned metal layer 115 to form a plurality of arrayed resonant units 104 allows for achieving the desired reflection effect with smaller resonant units 104, thereby improving antenna efficiency.

[0070] refer to Figure 5 and Figure 6 , Figure 5 is a top view of the first metal block and the second metal block in the resonance unit, Figure 6 This is a top view of the cross trace in the resonant unit. Figure 4-Figure 6 As shown, the resonant unit 104 includes: a first metal block 117 and a second metal block 118 arranged opposite each other along a first direction; a cross trace 119 located between the first metal block 117 and the second metal block 118; and multiple resonant units 104 arranged in rows and columns along a second direction. The first direction is perpendicular to the display component 100, and the second direction is parallel to the plane of the display component 100. That is, the first direction is parallel to the thickness of the electronic device, and the second direction is parallel to the plane of the electronic device. This method, based on the simple construction of two stacked, opposing metal blocks and the cross trace 119 between them, forms the resonant unit 104, which can effectively reflect antenna signals. The resonant unit 104 has a simple structure and is easy to manufacture.

[0071] Optionally, the first metal block 117 and the second metal block 118 may be symmetrical to each other, and the intersection of the metal lines of the cross trace 119 is perpendicular to the centers of the two metal blocks, so that the resonant unit 104 has a good reflection effect.

[0072] In one embodiment, the band-stop frequency of the reflective component 103 is 5.15G to 6.4G; the first metal block 117 and the second metal block 118 are square metal blocks with a side length of 2mm to 6mm; the cross trace 119 includes two perpendicularly intersecting metal wires with a length of 4mm to 8mm and a width of 0.1mm to 0.4mm; and the spacing between adjacent resonant units 104 is 0.5mm to 1.5mm. The spacing between adjacent resonant units 104 is the distance between adjacent resonant units 104 in the row direction or the distance between adjacent resonant units 104 in the column direction in the resonant unit array. The design parameters of the resonant units 104 provided in this embodiment can make the band-stop frequency of the reflective component 103 5.15G to 6.4G.

[0073] Optionally, in Figure 4-Figure 6 In the embodiment shown, the side length of the square metal block can be 4 mm, the length of the metal line in the cross trace 119 can be 6 mm, the line width of the metal line can be 0.3 mm, and the spacing between two adjacent resonant units 104 can be 2 mm. In this case, the simulation data of the reflective component 103 formed by the resonant unit 104 can be as follows: Figure 7 shown.

[0074] refer to Figure 7 , Figure 7 The graph of the reflection coefficient and transmission coefficient of a reflective component provided in an embodiment of the present application is shown in FIG. S11 is the reflection coefficient curve of the reflective component 103, and S21 is the transmission coefficient curve of the reflective component 103. Figure 7 As can be seen, reflective component 103 has a maximum reflection coefficient S11 in the 5.15 GHz to 6.4 GHz frequency band, achieving nearly 100% reflection of antenna signals in the 5.15 GHz to 6.4 GHz frequency band. This allows more antenna signals in this frequency band to be reflected toward spacing region 106 and radiated into space through spacing region 106. Furthermore, reflective component 103 has a relatively low transmission coefficient S21 in the 5.15 GHz to 6.4 GHz frequency band, effectively blocking antenna signals in the 5.15 GHz to 6.4 GHz frequency band from transmitting, thereby more antenna signals are reflected and improving antenna efficiency.

[0075] based on Figure 7 The simulation data shown shows that the Figure 4-Figure 6The reflective component 103 constructed from the structural resonant unit 104 exhibits excellent band-stop characteristics in the Wi-Fi 5G frequency band, effectively blocking antenna signal energy in this frequency band from being transmitted into the electronic device and effectively reflecting it toward the first side 101, thereby effectively improving antenna efficiency. Experimental data shows that this reflective component 103 can improve antenna efficiency in the 5G frequency band by approximately 15%.

[0076] refer to Figure 8 , Figure 8 A top view of a reflective assembly provided in an embodiment of the present application. Figure 4-Figure 6 as well as Figure 8 As shown, in order to make it easier to clearly see the graphic structure of each graphic metal layer 115 in the reflective component 103, Figure 8 The dielectric layer 116 is not shown in the figure, and the first metal block 117 and the second metal block 118 are transparently processed. In actual products, the first metal block 117 and the second metal block 118 may not be transparent.

[0077] Combine Figure 4-Figure 6 as well as Figure 8 As shown, the reflective component 103 includes three patterned metal layers 115, comprising a first patterned metal layer, a second patterned metal layer, and a third patterned metal layer stacked along a first direction. The first metal blocks 117 of each resonant unit 104 are located in the first patterned metal layer, the cross traces 119 of each resonant unit 104 are located in the second patterned metal layer, and the second metal blocks 118 of each resonant unit 104 are located in the third patterned metal layer. The first direction is perpendicular to the direction of the display component 100. This method allows the first metal blocks 117 of all resonant units 104 to be simultaneously fabricated using the first patterned metal layer, the cross traces 119 of all resonant units 104 to be simultaneously fabricated using the second patterned metal layer, and the second metal blocks 118 of all resonant units 104 to be simultaneously fabricated using the third patterned metal layer, facilitating the fabrication process of the resonant units 104 in the reflective component 103.

[0078] for Figure 4-Figure 6 、 Figure 8 In the reflective assembly 103 of the structure shown, the cross lines 119 of different resonant units 104 can be an integral metal grid structure. In this case, the interval between adjacent resonant units 104 can be the distance between adjacent metal blocks.

[0079] refer to Figure 9 and Figure 10 , Figure 9 A top view of a resonance unit provided in an embodiment of the present application is shown. Figure 10 for Figure 9A cross-sectional view of a resonant unit is shown. In this approach, reflective component 103 comprises a patterned metal layer including multiple separated cross traces 119, and resonant unit 104 includes cross traces 119. In this approach, the patterned metal layer is located on the surface of dielectric layer 116. This approach utilizes a single patterned metal layer to form resonant unit 104, enabling reflection of antenna signals through the relatively thin reflective component 103.

[0080] refer to Figure 11 , Figure 11 A top view of another reflective assembly provided in an embodiment of the present application. Figures 9-11 As shown, the reflective component 103 includes a patterned metal layer 115, which includes multiple cross traces 119. The resonant unit 104 also includes the cross traces 119. In this method, the multiple separated cross traces 119 include two perpendicularly intersecting metal lines, with a length L of 4 mm to 8 mm and a width W of 0.1 mm to 0.3 mm. The unit spacing D between adjacent resonant units 104 is 0.4 mm to 0.6 mm. Cross traces 119 designed to meet this method's parameters can ensure that the reflective component 103 has a band-stop frequency of 2.35 GHz to 2.65 GHz.

[0081] Optionally, the length L of the metal wire may be 5.5 mm, the width W of the metal wire may be 0.2 mm, and the unit spacing D between adjacent resonant units 104 may be 0.2 mm. In this case, the simulation data of the reflective component 103 formed by the resonant unit 104 may be as follows: Figure 12 shown.

[0082] refer to Figure 12 , Figure 12 The graph of the reflection coefficient and transmission coefficient of a reflective component provided in an embodiment of the present application is shown in FIG. S11 is the reflection coefficient curve of the reflective component 103, and S21 is the transmission coefficient curve of the reflective component 103. Figure 12 As can be seen, reflective component 103 has a maximum reflection coefficient S11 in the 2.35 GHz to 2.65 GHz frequency band, achieving nearly 100% reflection of antenna signals in the 2.35 GHz to 2.65 GHz frequency band. This allows more antenna signals in this frequency band to be reflected toward spacing region 106 and radiated into space through spacing region 106. Furthermore, reflective component 103 has a relatively low transmission coefficient S21 in the 2.35 GHz to 2.65 GHz frequency band, effectively preventing antenna signals in the 2.35 GHz to 2.65 GHz frequency band from transmitting, thereby more of them are reflected and improving antenna efficiency.

[0083] based on Figure 12 The simulation data shown shows that the Figures 9-11The reflective component 103 constructed with the structural resonant unit 104 exhibits excellent band-stop characteristics in the Wi-Fi 2.4 GHz band, effectively blocking antenna signal energy in this frequency band from being transmitted into the electronic device and reflecting it toward the first side 101, thereby significantly improving antenna efficiency. Experimental data shows that this reflective component 103 can improve antenna efficiency by approximately 10% in the 2.4 GHz band.

[0084] In the embodiment of the present application, the target antenna 102 can be a WiFi antenna that can transmit and receive WiFi 5G band signals and WiFi 2.4G signals. The frequency band of the antenna signal that the target antenna 102 can transmit and receive can be set according to needs, and the embodiment of the present application does not limit this.

[0085] In one embodiment, the reflective component 103 can be prepared on the surface of a separate dielectric layer 116 .

[0086] In another embodiment, the electronic device includes electronic components, which include insulating members, and the reflective assembly 103 is disposed on the insulating members. This approach allows the insulating members of existing electronic components in the electronic device to be directly reused as the dielectric layer 116 to support the reflective assembly 103, eliminating the need for a separate dielectric layer 116. This improves the integration of the electronic device and reduces the manufacturing cost of the reflective assembly 103. Alternatively, the insulating member can be a non-metallic component such as the audio cavity of the electronic device or a plastic bracket.

[0087] As can be seen from the above description, in the electronic device provided in the embodiment of the present application, by arranging the reflective component 103 on the side of the target antenna 102 away from the first side 101, the antenna signal radiated by the target antenna 102 to the second side can be reflected by the reflective component 103, and the antenna signal is reflected toward the first side 101, wherein the second side and the first side 101 are parallel and opposite to each other. The distance between the target antenna 102 and the second side is greater than the distance between the target antenna 102 and the first side 101. In this way, more antenna signals can be radiated to the space on the display side based on the spacing area 106, thereby improving antenna efficiency.

[0088] In the embodiment of the present application, the reflective component 103 is not limited to being arranged only on the side of the target antenna 102 away from the first side 101, but can also be arranged between the target antenna 102 and the third side or the fourth side of the electronic device. The third side and the fourth side can be Figure 1 The left and right sides of the electronic device.

[0089] As mentioned above, the reflective component can be a frequency selective surface, which includes periodically distributed resonant units 104. The frequency selective surface can reflect the antenna signal back based on the set band-stop characteristics, so that more antenna signals are radiated toward the display side based on the spacing area 106, thereby improving the antenna efficiency. The frequency selective surface can not only improve the antenna efficiency, but also enable the antenna to more effectively receive and radiate electromagnetic signals, thereby increasing the communication distance of the electronic device. Moreover, due to the simple structure of the frequency selective surface, it is easy to integrate with non-metallic insulating parts in electronic devices, so that no additional layout space is required.

[0090] Each resonant unit 104 in the frequency selective surface can be a metal patch, and the pattern structure and size parameters of the metal patch can be designed according to the required band-stop characteristics.

[0091] The various embodiments in the specification of this application are described in a progressive, parallel, or progressive and parallel manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the various embodiments can be referenced to each other. The embodiments provided in the embodiments of this application can be combined with each other if there is no contradiction.
