Transparent antenna preparation method based on film photoetching process and transparent antenna

Abstract

The invention discloses a transparent antenna preparation method based on a film photoetching process and a transparent antenna. The method comprises the following steps: S1, designing a low-visibility transparent antenna structure; S2, patterning the low-visibility transparent antenna structure on a film to manufacture a film mask; S3, cutting the transparent conductive film and the photosensitive dry film according to a preset size, and performing pretreatment on the transparent conductive film and the photosensitive dry film; S4, pasting a photosensitive dry film on the surface of the transparent conductive film, and exposing the conductive film pasted with the photosensitive dry film; S5, developing to expose the structural pattern of the transparent antenna; S6, etching the shape of the transparent antenna through the etching liquid; S7, removing the photosensitive dry film on the surface of the transparent conductive film, cleaning and drying to obtain the required transparent conductive film; S8, pasting the obtained transparent conductive film on a transparent plate; S9, cutting the transparent plate to obtain the required transparent antenna, and S10, connecting the transparent antenna to a radio frequency connector or a radio frequency cable. The method is high in machining precision and can be expanded to large-area preparation, the appearance of the manufactured antenna is not easy to perceive, and the antenna has the low-visibility characteristic.

Description

technical field [0001] The invention relates to the technical field of transparent antennas, in particular to a method for preparing a transparent antenna based on a film photolithography process and the transparent antenna. Background technique [0002] As a component capable of transmitting and receiving electromagnetic waves, the antenna plays an important role in the wireless communication system. In recent years, with the continuous development of wireless communication technology, people's requirements for wireless communication technology have also been continuously improved. Therefore, the antenna It has attracted more and more people's attention, and the research on antennas is also deepening. On some special vehicles or ships, huge antennas not only affect the appearance visually, but also are not conducive to safety and concealment in the actual environment. Due to the transparent conductive The film has the characteristics of light transparency and conductivity, ...

Problems solved by technology

Although the above scheme can meet the performance requirements of the antenna, the whole operation process is time-consuming and costly, and the waste liquid pollutes the environment and produces toxic gas, which is harmful to the health of the operator. The width of the processing line is about 200 μm, and it is difficult to achieve good concealment. Effect
