[0002] Transparent antenna is an innovative antenna design, which is composed of transparent conductive material and transparent dielectric matrix, has high transmittance to visible light, and can maintain its optical transparency while transmitting and receiving electromagnetic waves. Transparent antenna has attracted much attention in the communication field due to its advantages such as high overall aesthetics, flexible installation, excellent electrical performance indicators, small size, light weight, easy installation and low maintenance cost.

[0003] At present, there are two main production processes for transparent antennas: sheet production and roll-to-roll production. Sheet production has low output, but high cost and is difficult to transport, while roll-to-roll production has high output and low cost, but its substrate has the following problems:

[0004] 1. As time goes by, the light transmittance decreases and the substrate deteriorates (embrittlement, yellowing, etc.);

[0005] 2. The antenna pattern is easily damaged during transfer, resulting in an incomplete circuit. Summary of the invention

[0029] When the metal pattern layer is aligned with the second adhesive layer for lamination, the metal pattern layer on the first transparent substrate can be transferred to the second transparent substrate; wherein, during the lamination process, the second adhesive layer has a higher adhesion than the first adhesive layer through the lamination conditions;

[0030] The transferred second transparent substrate is attached to a target position.

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the invention claimed for protection, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0040] See also Figures 1 to 4 The first embodiment of the present invention provides a transparent antenna, which includes:

[0041] A first transparent substrate 10;

[0042] a first adhesive layer 20 coated on the first transparent substrate;

[0043] The metal pattern layer 30 is disposed on the first adhesive layer.

[0044] In this embodiment, the first transparent substrate 10 is a transitional plate, which can be a transparent material with a certain degree of flexibility, such as PC.

[0045] In this embodiment, the first adhesive layer 20 may be made of a material having adhesive properties, such as various glues.

[0046] In this embodiment, the metal pattern layer 30 is a metal mesh circuit formed by metal plating, and the metal mesh circuit has a radiation unit for radiating a signal.

[0047] The first transparent substrate 10, the first adhesive layer 20, and the metal pattern layer 30 can constitute an initial transparent antenna, and the initial transparent antenna can be produced by a roll-to-roll process.

[0048] A second transparent substrate 40; the second transparent substrate has better anti-aging performance than the first transparent substrate;

[0049] The second adhesive layer 50 is coated on the second transparent substrate 40 .

[0050] In this embodiment, the second transparent substrate 40 is made of a material having better material properties than the first transparent substrate 10 . For example, it is less likely to age, deteriorate, or reduce transparency over time or under sunlight than the first transparent substrate 10 .

[0051] For example, the second transparent substrate 40 may be glass or PMMA, but other similar transparent materials are also acceptable, and the present invention does not make any specific limitation.

[0052] The thickness of the first transparent substrate 10 and the second transparent substrate 40 may be 0.1 to 30 mm, preferably 1 to 20 mm.

[0053] In this embodiment, the second adhesive layer 50 is configured so that when the metal pattern layer 30 is pressed into alignment with the second adhesive layer 50, the metal pattern layer 30 on the first transparent substrate 10 can be transferred to the second transparent substrate 40; wherein, during the pressing process, the pressing conditions enable the second adhesive layer 50 to have a higher adhesion than the first adhesive layer 20.

[0054] In this embodiment, preferably, the thickness of the first adhesive layer 20 is 1 to 300 um, preferably 5 to 50 um; the thickness of the second adhesive layer 50 is 1 to 300 um, preferably 5 to 50 um.

[0055] In this embodiment, in order to transfer the metal pattern layer 30 from the first transparent substrate 10 to the second transparent substrate 40 , the second adhesive layer 50 needs to have a higher adhesion than the first adhesive layer 20 .

[0056] In addition, in order to ensure that the metal pattern layer 30 is not damaged during the transfer process, the difference in adhesion between the second adhesive layer 50 and the first adhesive layer 20 needs to be greater than 10 g / cm, preferably greater than 25 g / cm.

[0057] In order to generate such a large difference in adhesion, the adhesion of the first adhesive layer 20 is either set to be lower, or the second adhesive layer 50 with high adhesion is selected. However, when the adhesion of the first adhesive layer 20 is low, the metal pattern layer 30 may fall off, and when the second adhesive layer 50 with high adhesion is selected, there are problems such as high cost or toxic materials. In addition, even if the adhesion of the second adhesive layer 50 is high, if the adhesion of the first adhesive layer 20 is also relatively high, the metal pattern layer 30 may still be damaged.

[0058] Based on such considerations, in one implementation of this embodiment, the first adhesive layer 20 is configured to reduce its adhesion under the lamination condition, while the second adhesive layer 50 is configured to increase its adhesion under the lamination condition.

[0059] For example, the lamination condition is UV light lamination, the first adhesive layer 20 is UV viscosity-reducing adhesive; the second adhesive layer 50 is UV curing adhesive; or

[0060] The lamination condition is heating lamination, the first adhesive layer 20 is a heat-reducing adhesive; the second adhesive layer 50 is a heat-curing adhesive; or

[0061] The lamination condition is UV light humidification lamination, the first adhesive layer 20 is UV humidification debonding adhesive; the second adhesive layer 50 is UV humidification curing adhesive; or

[0062] The lamination condition is UV light heating lamination, the first adhesive layer 20 is UV heating viscosity reducing adhesive; the second adhesive layer 50 is UV heating curing adhesive.

[0063] That is to say, in this embodiment, the lamination conditions here have an opposite effect on the first adhesive layer 20 and the second adhesive layer 50. The adhesion of the first adhesive layer 20 is reduced under the lamination conditions, while the adhesion of the second adhesive layer 50 is increased under the lamination conditions. The advantage of this is that, on the one hand, a sufficiently large adhesion difference can be generated between the second adhesive layer 50 and the first adhesive layer 20, so that the metal pattern layer 30 is more easily transferred. On the other hand, since the adhesion of the first adhesive layer 20 is reduced under the lamination conditions, the metal pattern layer 30 is less likely to be damaged during the transfer, thereby ensuring the integrity of the metal pattern layer 30.

[0064] Of course, in other embodiments of the present invention, the first adhesive layer 20 and the second adhesive layer 50 may be configured to increase their adhesion under the lamination conditions, but the adhesion increase rate of the first adhesive layer 20 is lower than that of the second adhesive layer 50 .

[0065] For example, the lamination condition is pressure lamination. As the pressure increases, although the adhesion of the first adhesive layer 20 and the second adhesive layer 50 increases, the adhesion increase rate of the first adhesive layer 20 is lower than that of the second adhesive layer 50, which can also produce an adhesion difference.

[0066] In summary, the transparent antenna provided in this embodiment combines the advantages of both sheet production and roll-to-roll production. The roll-to-roll production method is used to form the initial transparent antenna, which is convenient for reducing costs and transportation. During installation, the second transparent substrate 40 with better materials is used as a carrier for the metal pattern layer 30, which can slow down the decrease in light transmittance and degradation (embrittlement, yellowing, etc.) of the substrate over time.

[0067] In addition, through the design of the first adhesive layer 20 and the second adhesive layer 50, the metal pattern layer 30 can be prevented from being damaged during the transfer, thereby ensuring the integrity of the circuit.

[0068] See also Figure 5The second embodiment of the present invention further provides a method for installing the transparent antenna as described above, which comprises:

[0069] S201, providing a first transparent substrate, wherein a first adhesive layer is coated on the first transparent substrate, and a metal pattern layer is formed on the first adhesive layer;

[0070] S202, providing a second transparent substrate, and coating a second adhesive layer on the second transparent substrate; wherein the second transparent substrate has better anti-aging performance than the first transparent substrate;

[0071] S203, when laminating in a manner that the metal pattern layer is aligned with the second adhesive layer, the metal pattern layer is transferred to the first transparent substrate; wherein, during the laminating process, the second adhesive layer has a higher adhesion than the first adhesive layer according to the laminating conditions;

[0072] S204, attaching the transferred second transparent substrate to a target position.

[0073] It should be noted that when the second transparent substrate 50 with the transferred metal pattern layer is attached to the target position, an adhesive layer may be coated on the metal pattern layer to ensure the stability of the attachment.
