A vehicle-mounted sky roof integrated with a transparent film antenna and a manufacturing method thereof

Abstract

The application discloses a kind of integrated transparent film antenna's vehicle-mounted starry sky top, including transparent substrate layer, metal grid conductive layer, transparent film antenna layer, light guide layer, light source module and protective layer;Through metal grid conductive layer, light source driving and additional function integration are realized, through misplacement layout, the transparent film antenna layer of insulating isolation realizes multi-band wireless communication, and the integration design of both realizes spatial reuse and electromagnetic compatibility.The application also discloses its preparation method, including preparation metal grid conductive substrate, etching conductive circuit, depositing film antenna, composite light guide layer and light source, sticking protective layer and testing, die cutting installation.The problems of traditional vehicle-mounted starry sky top, such as single function, vehicle-mounted antenna installation space conflict, signal is susceptible to interference, poor structure compatibility are solved, the collaborative integration of starry sky light and shadow display and multi-band wireless communication is realized, and the development needs of car intelligentization and networking are adapted.
