Scientists from Stanford University and the American University of Beirut have developed a prototype device that could revolutionize communications at disaster sites. The device, known as a “bi-stable deployable quadrifilar helix antenna,” is a simple tubular antenna made of woven strips of conductive fiber composite material. It can be easily adjusted to emit a low-power signal in all directions for ground-based radio communications or a high-power signal in a specific direction for satellite communications. The lightweight and versatile design of the antenna makes it a more practical and cost-effective solution than traditional heavy satellite dishes. The researchers hope that their invention will improve communication capabilities in areas where it is lacking.
