Tesla has filed a patent for a vehicle roof assembly that enables direct satellite communication, hinting at potential Starlink integration. The design uses radio frequency transparent materials to allow antennas to be hidden within the roof structure. This could provide seamless connectivity in areas without cellular coverage.
On December 17, 2025, Tesla disclosed a new patent application titled “Vehicle Roof Assembly with Radio Frequency Transparent Material,” identified as U.S. Patent 2025/0368267 A1. The filing describes a multi-layer roof structure made from polymer blends such as polycarbonate, acrylonitrile styrene acrylate (ASA), or ABS, which are designed to be radio frequency (RF) transparent. These materials allow satellite signals to pass through with minimal interference, unlike traditional metal or glass roofs that block or attenuate them.
The patent explicitly states that this assembly facilitates the integration of “antennae directly into the roof structure, facilitating clear communication with external devices and satellites.” While it does not mention Starlink by name—a common practice in patents—the connection is evident given Elon Musk's involvement with both Tesla and SpaceX's satellite internet service. The design ensures compliance with Federal Motor Vehicle Safety Standards (FMVSS), including head-impact regulations, maintaining structural integrity.
Currently, Tesla vehicles depend on cellular networks for features like Autopilot data, software updates, and streaming. However, cellular coverage is limited in remote areas. This innovation could enable vehicles to switch seamlessly between 5G cellular and satellite networks, eliminating dead zones in rural, desert, or mountainous regions. For instance, it would support navigation, cloud-based driver assistance, and over-the-air updates in off-grid locations.
Electrek notes that while satellite connectivity may not be essential for autonomous driving—due to reliability risks—it could appeal as an option for users in remote areas. A commenter highlighted potential cost savings by shifting from carrier fees to in-house Starlink services. Whether this becomes a production feature remains to be seen, as not all patents reach vehicles.
