Key Takeaways:

NASA is developing an "active phased array aerogel antenna" to prevent critical communication losses ("dropped calls") in future aircraft like drones and eVTOL air taxis.
This ultra-lightweight antenna, embedded under the aircraft's skin, uses electronically steered radio waves to ensure reliable communication without increasing drag or sacrificing power.
Made from aerogel, a highly porous and flexible material, the antenna has been successfully tested with both geostationary and low-Earth orbit satellites.
The innovation aims to significantly improve the safety of drone and eVTOL operations, particularly in urban, highly populated areas where these aircraft are expected to operate.

Engineers at NASA are developing a solution to address the potential for “dropped calls” in drones, self-flying electric vertical takeoff and landing (eVTOL) air taxis, and other future aircraft.

The space agency on Tuesday said that by the end of the year, researchers aim to design, build, and test what it describes as an “active phased array aerogel antenna” that can be embedded under an aircraft’s skin. The idea is to address communication delays and losses in aircraft, which typically communicate with ground stations using signals transmitted via satellite relay.
