By integrating multiple antennas on the front cover plate, the position of the antenna 112 can be closer to the front surface of the electronic device 10, which can reduce the shielding and attenuation of the signal of the antenna 112 and improve the transmission performance of the antenna 112. In other embodiments, the cover plate 11 is not limited to the above structure, for example, the cover plate 11 does not include a touch layer.

In another embodiment, as shown in fig. 6 and 7, the cover 11 is a rear cover, and the antenna 112 is also located between the cover base 111 and the display 12.

A coating 114 is positioned between the color layer 115 and the antenna 112 (fig. 6); alternatively, the plated layer 114 is disposed between the cover substrate 111 and the antenna 112, and the color layer 115 is disposed on a surface of the antenna 112 facing away from the plated layer 114 (fig. 7). The plating layer 114 is formed by vacuum sputtering a metal plating film on the cover substrate 111, thereby obtaining a trademark (LOGO) plating film, a glare texture plating film, and the like, and obtaining a more beautiful appearance and a more comfortable hand feeling. The color layer 115 may be a substrate obtained by printing ink and curing the ink, and the color layer 115 can show the appearance effect in the coating layer 114. In this implementation, the plurality of antennas are integrated in the rear cover plate, so that the position of the antenna 112 can be closer to the rear surface of the electronic device 10, thereby reducing the shielding and attenuation of signals of the antenna 112 and improving the transmission performance of the antenna 112.

In another embodiment, as shown in fig. 8, the cover plate 11 is a rear cover plate, and the antenna 112 is located on a side of the cover plate base 111 facing away from the display 12. The cover 11 further includes a shielding layer 116, the shielding layer 116 is stacked on the antenna 112, and the antenna 112 is located between the cover substrate 111 and the shielding layer 116. In this embodiment, the cover plate 11 may also include a color layer 115 and a plated layer 114, in this case, the plated layer 114 is located between the color layer 115 and the cover plate base 111, the antenna 112 is located on a side of the cover plate base 111 facing away from the plated layer 114, the protective layer 116 is located on a side of the antenna 112 facing away from the cover plate base 111, and the display 12 is located on a side of the color layer 115 facing away from the plated layer 114.

In this implementation, the plurality of antennas are integrated in the rear cover plate, and the antenna 112 is located outside the cover plate base 111, so that the antenna 112 is located closer to the outer surface of the electronic device 10, shielding and attenuation of signals of the antenna 112 can be greatly reduced, and transmission performance of the antenna 112 is improved. In other embodiments, the cover plate 11 is not limited to the above-described structural form.

The antenna 112 of the embodiment includes a substrate 1123 and a conductive mesh 1121, and the material of the substrate 1123 may be, but is not limited to, a transparent Polymer film, such as PET, CPI, PC, PMMA, Cyclic Olefin Polymer (COP). The conductive mesh 1121 is formed on the substrate 1123, the conductive mesh 1121 is formed by a plurality of conductive wires in a criss-cross manner, the conductive mesh 1121 includes a plurality of meshes, and the shape of each mesh may be a regular polygon (such as a diamond) or an irregular polygon.

In one embodiment, as shown in fig. 9, a transparent polymer layer 1122, such as an Ultraviolet (UV) curable adhesive, may be applied to one side of the substrate 1123. The transparent polymer layer 1122 is provided with a grid-shaped groove on a side surface away from the substrate 1123, and the groove is filled with a conductive material, and finally the conductive material is cured to form a conductive grid 1121. The area of the region other than the lattice-shaped grooves on the surface on the transparent polymer layer 1122 side provided with the lattice-shaped grooves may account for 80% or more, for example, 85% or 90% of the surface area on the transparent polymer layer 1122 side. Specifically, a grid-shaped groove with a preset shape can be formed on the surface of the transparent polymer layer 1122, which is far away from the substrate 1123, by means of stamping, and the shape of the grid-shaped groove is matched with the shape of the conductive material; further, a conductive material (such as nano silver ink) may be filled in the grid-shaped grooves by using a doctor blade coating technique, and then sintered to form the conductive wire, wherein the conductive material is conductive metallic silver. In other embodiments, the conductive wire may also be made of other conductive materials, such as carbon nanotube, graphene, conductive polymer, and the like. The conductive mesh 1121 is prepared by a simple process, and the adopted conductive material has a low price, so that the manufacturing cost of the antenna 112 can be further reduced.

In another embodiment, as shown in fig. 10, a conductive material may be deposited on the substrate 1123 by vacuum evaporation or magnetron sputtering to form a conductive film. And etching the conductive film after the aging treatment to obtain a plurality of conductive grids 1121 with leads arranged in a criss-cross manner. The etching method for the conductive film can be a yellow light process method, an acid-resistant etching method or a laser etching method. For example, a yellow light process is used, and the specific process is to sequentially use exposure, development, and etching processes to fabricate the conductive mesh 1121. The conductive material may be, but is not limited to, copper-indium tin oxide (Cu-ITO), and copper-nickel alloy. In other embodiments, the conductive mesh 1121 is not limited to the above-described fabrication method.

Since the conductive wires of the conductive mesh 1121 in the above embodiments are not transparent, the conductive mesh 1121 may be exposed when the antenna 112 is located between the cover plate 11 and the display 12. To avoid this problem, the line width of the mesh may be reduced and the side length of the mesh may be increased to increase the light transmission area of the antenna 112, thereby increasing the light transmittance of the conductive mesh 1121. Specifically, in one embodiment, the substrate 1123 is a film made of transparent material, the conductive mesh 1121 is formed by criss-crossing conductive wires having a line width of 0.5 μm to 4.5 μm, and the side length of the mesh in the conductive mesh 1121 is in the range of 50 μm to 500 μm, so that the antenna 112 can be disposed in the cover plate 11 of the electronic device 10 shown in fig. 1 without the conductive mesh 1121 being exposed. The side length of the mesh refers to the side length of a polygon formed by the wire portions in any one of the mesh units enclosed into the conductive mesh 1121. The side length of any side of the grid can be a random one of 50-500 μm, and the side lengths of the grid can be the same or at least one side is different from the rest. The depth of the conductive mesh 1121 may be 0.5 μm to 3.5 μm, and the depth of the conductive mesh 1121 refers to the maximum width of the conductive mesh 1121 in the normal direction of the surface of the substrate 1123 laid on the conductive mesh 1121. The aperture ratio (the aperture ratio is the ratio of the area of the substrate 1123 in the region where the conductive mesh 1121 is formed, which does not contain the conductive material to the total area of the region) of the conductive mesh 1121 with such a size can reach at least 85%, and the transmittance can reach at least 80%, so that the appearance performance is good, the sheet resistance of the conductive mesh 1121 is low, and the performance of the antenna 112 is good. By setting the ranges of the line width and the side length of the conductive mesh 1121, the aperture ratio and the light transmittance of the conductive mesh 1121 can be increased, so that the transparency of the antenna 112 is increased, and the antenna 112 does not expose the conductive mesh 1121. In other embodiments, the conductive mesh 1121 is not limited to the above dimensions.

In this embodiment, as shown in fig. 11, the conductive mesh 1121 includes at least two antenna regions 1121 a. In fig. 11, the antenna regions 1121a are represented by a region surrounded by a dotted line (a portion surrounded by a dotted line is a circle is a partially enlarged view), and the wires in each antenna region 1121a are connected to each other. The wires forming the mesh are arranged at a dense interval so that the antenna region 1121a can radiate or receive an electromagnetic wave signal as a radiator. The boundaries of the antenna regions 1121a may serve as the boundaries of the conductive mesh 1121, or the antenna regions 1121a may be located within the boundaries of the conductive mesh 1121.

The conductive mesh 1121 includes first isolation regions 1121b, the first isolation regions 1121b are regions other than the antenna regions 1121a, the first isolation regions 1121b may be composed of a broken mesh, and the first isolation regions 1121b separate different antenna regions 1121a to electrically isolate any one of the antenna regions 1121a from the remaining antenna regions 1121 a. By dividing the conductive mesh 1121 into a plurality of antenna regions 1121a by the first isolation region 1121b, each antenna region 1121a can be used as an antenna, so that a plurality of antennas can be integrated on the same substrate 1123 to form a film layer, thereby greatly improving the integration level of the antenna 112, reducing the occupied structural space, and greatly saving the internal construction space of the electronic device 10.

In one embodiment, as shown in fig. 11, at least one wire of each of at least a portion of the meshes of the first isolation region 1121b is disconnected to form a gap 1121 c. Here, the gaps 1121c may be present in a part of the meshes of the first isolation regions 1121b, or the gaps 1121c may be present in all the meshes of the first isolation regions 1121 b. A part of the wires of a single mesh may be disconnected to form the gap 1121c, or all of the wires of a single mesh may be disconnected to form the gap 1121 c. The grid of gaps 1121c formed in the first isolation region 1121b is adjacent to the grid of antenna regions 1121 a. The width of the gaps 1121c formed by the grid disconnection in the first isolation regions 1121b is not more than 20 μm, and preferably, the width of the gaps 1121c is about 5 μm to 6 μm. In this embodiment, the first isolation region 1121b is separated by grid wires to form a gap 1121c, so that different antenna regions 1121a can be separated, the electrical conduction between the antenna regions 1121a can be blocked, the electrical isolation between any antenna region 1121a and the other antenna regions 1121a can be ensured, and the integration of multiple antennas can be realized.

Since the antenna region 1121a only covers a portion of the substrate 1123, when the difference between the reflectivity of the conductive material and the reflectivity of the substrate 1123 is large, the optical effect of the light reflected by the surface of the conductive material and the bottom surface of the substrate 1123 is large, so that the user can easily see the conductive mesh 1121. Therefore, by breaking at least part of the wires in at least part of the mesh of the first isolation regions 1121b to form the gaps 1121c, the deviation of light transmittance between the antenna regions 1121a and the first isolation regions 1121b can be reduced while ensuring that the antenna regions 1121a are electrically disconnected from each other, thereby reducing the visual visibility of the conductive mesh 1121 in the antenna 112. In other embodiments, the first isolation region 1121b is not limited to the above-described formation.

Fig. 12 and 13 are enlarged partial views of the conductive mesh 1121 of the antenna 112. Fig. 12 and 13 show a mesh forming the antenna region 1121a and a mesh forming the isolation mesh 1121b, respectively. As an example, all the wires of each mesh of the first isolation regions 1121b are disconnected in fig. 12 to form gaps 1121c, and the meshes as the antenna regions 1121a and the meshes of the first isolation regions 1121b are square in fig. 12 and 13. As shown in fig. 12 and 13, the grid has a first side length L1 and a second side length L2, the width W of the sides of the grid is the line width described above, and the width of the gap 1121c in the grid is H. The edge of the grid is broken to form a gap 1121c, and the gap 1121c may be disposed at any position of the edge of the grid, such as at the middle position of the edge of the grid. Preferably, the position of the gap 1121c is the same in each side of each mesh.

When the grid is formed, the line width of the wires forming the antenna region 1121a and the line width of the wires forming the first isolation region 1121b may be adjusted to ensure uniform light transmittance of the antenna 112. If the line width of the wire forming the first isolation region 1121b and the line width of the wire forming the antenna region 1121a are substantially the same or uniform, the aperture ratio of the first isolation region 1121b provided with the gap 1121c is higher than that of the antenna region 1121 a. Such a deviation in light transmittance may cause a Moire (Moire) fringe phenomenon in which interference fringes are generated by overlapping two or more periodic wave patterns. If the antenna 112 is disposed in the electronic device 10, display quality may be degraded. Therefore, by setting the line width of the wire forming the antenna region 1121a to be different from the line width of the wire forming the first isolation region 1121b, for example, by making the line width of the wire of the antenna region 1121a smaller than the line width of the wire of the first isolation region 1121b, the aperture ratio of the first isolation region 1121b can be adjusted to be close to or the same as the aperture ratio of the antenna region 1121a, so that the light transmittances of the antenna region 1121a and the first isolation region 1121b are approximately the same.

In one embodiment, the conductive mesh 1121 may further include a second isolation region 1121d, the second isolation region 1121d is formed by a plurality of wires that are crisscrossed, and the wires of the second isolation region 1121d are connected to each other. As shown in fig. 14, the second isolation region is indicated by 1123d in fig. 14, and the second isolation region 1121d is provided in the first isolation region 1121b to divide the first isolation region 1121 b. The dividing means that the second isolation region 1121d can divide the first isolation region 1121b into a plurality of unconnected regions. The second isolation region 1121d is spaced apart from any of the antenna regions 1121a, i.e., the boundary of the second isolation region 1121d does not overlap with the boundary of any of the antenna regions 1121 a. At least one antenna region 1121a is surrounded by a second isolation region 1121d, for example, the second isolation region 1121d only surrounds one antenna region 1121a, or at least two second isolation regions 1121d (as shown in fig. 15) are provided, and one second isolation region 1121d correspondingly surrounds one antenna region 1121 a. Specifically, when the second isolation region 1121d encloses a certain antenna region 1121a, the second isolation region 1121d may be enclosed as a closed region alone, or the second isolation region 1121d and the boundary of the conductive mesh 1121 together enclose a closed region, so as to enclose the antenna region 1121a in the closed region. The enclosed area may be of any pattern. By providing the second isolation region 1121d and dividing the first isolation region 1121b into two regions that are not connected to each other, it is possible to further suppress or block interference between the antenna regions 1121a, improve the signal transmission stability of the antenna regions 1121a, and improve the performance of the antenna 112. In other embodiments, the second isolation region 1121d is not required.

In one embodiment, the substrate 1123 includes a visible area and a non-visible area located at the periphery of the visible area, the conductive mesh 1121 is disposed on the visible area, the non-visible area has a bonding area, the bonding area has a plurality of wires, and the number of the wires is multiple. All of the wires of antenna region 1123a extend to the bonding areas and are electrically connected to the traces of the bonding areas. Accordingly, the electronic device 10 may include a flexible circuit board that electrically connects the traces of the bonding area to feed the antenna region 1123 a. The flexible circuit board is used for feeding the antenna area 1123a, the process is mature, and the antenna stability is good.

In another embodiment, the electronic device 10 may include radio frequency circuitry for processing antenna signals. Accordingly, the substrate 1123 may have a coupling region located in an invisible region of the substrate 1123, and all of the antenna regions 1123a are connected to the coupling region and coupled to the rf circuit through the coupling region to realize radiation or reception of an electromagnetic wave signal, wherein the coupling mode may include pad (pad) point coupling or in-plane coupling. In other embodiments, the antenna region 1123a may be electrically connected in other manners, and is not limited to the above-described electrically connecting manner.
