Unlike simple dipole antennae, like those on old TVs, which produce linearly polarized light, helical antennae produce circularly polarized light. This type of light is characterized by its capacity to resist degradation over long distances, which makes helical antennae very useful implements in space and deep-sea exploration. A common problem with these antennae, though, is that they can be far too large and bulky to fit onto satellites for quality space scans. This project aims to provide possible remedies to that by constructing an expandable helical antenna.
