Vehicle-mounted screen with built-in low-orbit satellite communication antenna and manufacturing method of vehicle-mounted screen

Abstract

The invention discloses a vehicle-mounted screen with a built-in low-orbit satellite communication antenna and a manufacturing method of the vehicle-mounted screen. A vehicle-mounted screen with a built-in low-orbit satellite communication antenna comprises a vehicle-mounted screen body, a protective cover plate arranged on the periphery of the vehicle-mounted screen body and the low-orbit satellite high-frequency communication antenna arranged on the back face of the vehicle-mounted screen body or the back face of the protective cover plate, and the low-orbit satellite high-frequency communication antenna comprises a base material and wire layers arranged on the front face and the back face of the base material. The conductor layer is used for receiving low-orbit satellite signals; the wire layer is provided with wires with the width of 5-25 microns, and the interval between the wires is also 5-25 microns; the base material is a low-identification-degree to transparent material; and at least one layer of base material is provided. Due to the fact that the wires of 5-25 micrometers are adopted, and the interval between the wires is also 5-25 micrometers, the overall size of the antenna is greatly reduced. A huge and heavy dish-shaped satellite receiving antenna is changed into a low-orbit satellite antenna which is low in identification degree, transparent, light, easy to carry, efficient, stable and competitive in price.

Description

technical field [0001] The invention relates to a vehicle-mounted screen with an antenna, more specifically to a vehicle-mounted screen with a built-in low-orbit satellite communication antenna and a manufacturing method thereof. Background technique [0002] With the rapid and vigorous development of 5G communication networks and low-orbit satellites, high-quality low-orbit satellite broadband services play a very critical role in areas where fiber optic broadband cannot be laid or 5G machine stations cannot be built, especially in the military. , emergency relief, unmanned driving, telemedicine, geological and hydrological monitoring, and education in remote mountainous areas. [0003] The receiving antenna of low-orbit satellites with high quality, high reliability, high portability, and competitive price is one of the key elements to determine whether it can be commercialized and widely popularized. [0004] There are many shortcomings in the traditional satellite dish ...
