Document number U.S. 2025/0368267 describes panels made of polycarbonate and other polymers that better transmit radio frequency signals than metal and glass. Due to the lower rigidity of such materials, Tesla proposes a multi-layer construction — up to four layers — to compensate for strength, reduce noise, and vibration.
The patent states that the use of polymer blends allows modules inside and outside the car to transmit signals to satellites and other devices. Such a roof could theoretically be applied to mass models, including Model 3 and Model Y, providing a stable connection with Starlink in areas with poor mobile network coverage.
At present, this is only a patent application, and there is no guarantee that the solution will reach mass production.
Currently, Tesla offers standard connectivity, which includes navigation and basic vehicle functions, with many features available via Wi-Fi. The company also offers a premium package, available in the US for $9.99 per month, which includes features such as real-time traffic visualization and streaming services through mobile networks.
