"cheap, small, light, easy manufacture... converts electromagnetic waves from linear to circular polarization, improving signal reliability, remote sensing, between satellites/ ground stations... minimizes signal degradation from polarization mismatch, multipath interference, rain fading, ionospheric disturbances, imprecise antenna alignment.,, doubles channel capacity using right-/ left-hand circular polarizations... tiny cells of geometrically patterned copper laid over circuit board... works across a wide range of frequencies"
