Now, beach ball shaped inflatable antenna that fits into your backpack
One of the biggest issues in setting up satellite communications networks is the antenna. But now, with a new technology this problem can be solved.
GATR Technologies, which has designed an inflatable 1.2-metre satellite antenna that can fit into a backpack and be carried by a single person. The company”s antenna looks something like a beach ball. It is a double-layered sphere, with one layer a nylon mesh and the other made from sail material, and the antenna at the centre, reports New Scientist.
The receiving dish divides the sphere”s interior into two chambers and by applying pressure to one chamber you can push the antenna into a parabolic shape.
The company already sells a larger, 2-metre version but this one is small enough to fit in an airline”s hand luggage area when folded.
