- phkahler 6y agoI believe the answer is yes. I recall something a few years ago where they modified a dish antenna to create a form of spiral signal. Multiple variations could be used at the same base frequency.
- mturmon 6y agoYes, see https://en.wikipedia.org/wiki/Orbital_angular_momentum_multiplexing https://en.wikipedia.org/wiki/Orbital_angular_momentum_multi...
- packet_nerd 6y agoCircular polarized antennas are often used in ham radio especially to communicate with satellites[1]. I'm not expert enough to know, is this the same physics as what the article is talking about?
