this cirular polarization is primarily used in optical usages at this point since each device used to produce the effect will be limited to one wave length until they figure out how to build a variable circular polarizing device. An antenna can do it but you have to use a spiral metal tube that is not variable and would only work for one wavelength and perhaps it harmonics.
