Preferably, in this embodiment, the transparent conductive silver paste and the pigment dye are fully mixed according to the volume percentage of 98.20% to 99.55% of the transparent conductive silver paste and the volume percentage of 0.45% to 1.80% of the pigment dye, so as to obtain the colored conductive silver paste.
In this embodiment, after forming the color antenna on the antenna support, the method for manufacturing the color antenna further includes: and standing the antenna support for 180-240 seconds at the temperature of 15-28 ℃ and the RH of 30% -80% so as to solidify the color conductive silver paste.
In addition, in this embodiment, before forming the color antenna on the antenna holder, the method for manufacturing a color antenna further includes: and wiping the area of the antenna bracket corresponding to the color antenna by using absolute ethyl alcohol.
Hereinafter, a method for manufacturing the transparent antenna provided in this embodiment will be described with an embodiment. In this embodiment, the pad printing process of the transparent antenna is completed by a pad printing machine.
Before the work begins, the temperature of the work environment is confirmed to be within the range of 15-28 ℃, and the humidity is confirmed to be within the range of 30% -80% RH.
The transfer printer is firstly confirmed to be normal in electrical property and can work normally, and the machine is clean and has no impurities.
And (5) preparing the colored conductive silver paste. In this embodiment, specifically, a black dye is selected, and the transparent conductive silver paste and the black dye are fully mixed to obtain the black conductive silver paste, wherein the volume percentage of the transparent conductive silver paste is 99.3 ± 0.1%, and the volume percentage of the pigment dye is 0.7 ± 0.1%.
Then, black conductive silver paste was poured into the ink cartridge. The black conductive silver paste is not easy to pour into the transfer printing mould to be overfilled, and the silver paste leakage in the transfer printing process is prevented from influencing the transfer printing effect.
Then, the transfer printing steel plate is drawn with the one side of transparent antenna domain just to the ink horn, makes transfer printing steel plate and ink horn in close contact with, so alright make black conductive silver thick liquid can coat on the transfer printing steel plate. Specifically, as shown in fig. 2, the color antenna layout on the transfer printing steel plate is engraved in shade, that is, the layout surface of the color antenna is lower than the surface of the transfer printing steel plate, so that the black conductive silver paste of the color antenna layout part can be retained while the black conductive silver paste on the surface of the transfer printing steel plate is scraped.
Then, the ink box is connected with the pad printing steel plate and is arranged on the pad printing machine. At the moment, the ink box faces upwards, the transfer printing steel plate faces downwards, the transfer printing steel plate is fixed on the working platform, and the ink box is fixed with the transfer printing machine head and can reciprocate on the working platform. The pad printer head is double head, the head near the inner side is fixed with the ink box, the head near the outer side is fixed with the printing head, and the printing head is generally an elastic rubber block.
After the pad printing equipment is installed, the power supply of the pad printing machine is started, and the fixed seat of the antenna bracket is adjusted through the movement of the specific pad printing machine head. Specifically, the antenna bracket is placed in the fixed seat, the pad printing machine is controlled to move the printing head to the outer side, namely the printing position, the antenna bracket is confirmed to be positioned in the area corresponding to the printing head, and the black antenna is ensured to be pad printed on the correct position of the antenna bracket; locking the permanent seat for positioning.
Thereafter, normal pad printing operation may be started, and the black antenna may be printed on the antenna holder by pad printing. The antenna support is made of common materials, such as black PI, PET, PC, PA, ABS, etc.
The thickness of the color antenna is preferably 9 μm to 15 μm in order to secure the electrical performance of the color antenna. Meanwhile, in order to ensure that the forming area of the color antenna is not polluted by impurity, dust and the like, the area of the antenna bracket corresponding to the forming area of the color antenna can be wiped by using absolute ethyl alcohol before pad printing, so that the antenna bracket can be cleaned.
Since the pad-printed color antenna is initially in a liquid state on the antenna support, the antenna support with the pad-printed color antenna needs to be left for a period of time to solidify the color conductive silver paste. Contact with other objects is avoided during this period to prevent the structure of the color antenna from being damaged. In the embodiment, when the ambient temperature is 15-28 ℃ and the humidity is 30% -80%, the time required for curing is 180-240 seconds.
If the color antenna is offset in pad printing, or the performance of the antenna does not meet the standard due to the insufficiency of the color conductive silver paste, or the color antenna does not meet the receiving standard due to other reasons, the color antenna can be wiped by absolute ethyl alcohol so as to erase the color conductive silver paste. Therefore, it can be seen that the manufacturing method of the color antenna provided by the embodiment is beneficial to saving cost, and the antenna bracket can be reused after the color antenna is removed. Meanwhile, it should be noted that since the absolute ethyl alcohol can remove the color conductive silver paste, the antenna bracket printed with the color antenna should be far away from the absolute ethyl alcohol, so as to prevent the color antenna from being damaged. In addition, since the color antenna is not easily distinguished from the antenna stand due to the color of the antenna stand, the printed antenna stand and the non-printed antenna stand should be placed differently, and at the same time, should be tested by a test station to confirm the performance of the color antenna.
It should be noted that the colored conductive silver paste has a certain corrosiveness, so people should be protected during the operation.
As shown in fig. 3, the color antenna 200 includes a first branch 210 in a straight line shape, a second branch 220 in a T shape, and a third branch 230 in a C shape; one end of the second branch node 220 is communicated with the middle part of the first branch node 210; one end of the third branch 230 is connected to one end of the first branch 210; the second branch node 220 and the third branch node 230 are located on the same side of the first branch node 210, and the third branch node 230 is located on a side of the second branch node 220 away from the first branch node 210.
The color antenna provided by the embodiment has the color consistent with that of the antenna bracket, so that the antenna and the bracket can be perfectly fused in appearance. Meanwhile, the second branch 220 of the color antenna provided by the embodiment is T-shaped, so that the middle area of the first branch 210 and the second branch 220 can generate middle and low frequency coupling, and the bandwidth of the middle and low frequency is increased; the third branch 230 is C-shaped, which can generate high frequency coupling, increasing the bandwidth of high frequency, and the radiation end of the third branch 230 is close to the second branch 220, which can generate coupling at medium and high frequency, thereby increasing the bandwidth of medium and high frequency. Therefore, the antenna has a very wide frequency range, and can meet the requirements of low, medium and high frequency bands.
Furthermore, in this embodiment, the width of the trace of the color antenna is 2-5 mm. Thus, the highest coupling efficiency and the lowest electromagnetic loss among the branches of the antenna can be ensured.
Further, the third branch 230 includes a first strap 231, a second strap 232, a third strap 233 and a fourth strap 234 connected in sequence, and the first strap 231, the second strap 232, the third strap 233 and the fourth strap 234 form a C shape by being surrounded by 90 ° each other. The angle of 90 degrees can not only improve the coupling efficiency between the strips, but also enable the radiation angle of the antenna to be omnidirectional, thereby being beneficial to receiving and transmitting signals.
In summary, the color antenna and the manufacturing method thereof provided in this embodiment include: preparing color conductive silver paste, a transfer printing steel plate and an antenna bracket, wherein a layout of a color antenna is drawn on the transfer printing steel plate, and the color of the color conductive silver paste is consistent with that of the antenna bracket; uniformly coating the color conductive silver paste on one surface of a transfer printing steel plate, which is drawn with a pattern of the color antenna, and erasing the color conductive silver paste outside the pattern area of the color antenna on the transfer printing steel plate; and printing the colored conductive silver paste on the transfer printing steel plate on the antenna bracket by using a transfer printing process so as to form a colored antenna on the antenna bracket.
