Lightweight woven antenna could replace field-deployed dishes | A multi-stable deployable quadrifilar helix antenna with radiation reconfigurability for disaster-prone areas
Ordinarily, in order to establish communications at locations such as disaster sites, rescuers have to transport and set up relatively bulky, costly satellite dishes. Soon, however, a simple tubular antenna made of woven strips of material may get the job done.
Ordinarily, in order to establish communications at locations such as disaster sites, rescuers have to transport and set up relatively bulky, costly satellite dishes. In its long state – and when connected to electronics such as a transceiver, ground plane and battery – the antenna emits a low-power signal in all directions, allowing for radio communications with ground-based team members. This means that when pulled or pushed by hand, it will automatically pop itself into the desired configuration – so there's no guesswork as to whether or not it's been properly deployed, whether at a disaster site, battlefield, or potentially even in a spacecraft.
