circular polarization
1. the radiation. Intensity is maximum along the normal to the dipole axis
2. the current distribution along length is uniform irrespective of the length
3. the effective length equals. physical length
4. the input impedance is independent of the location of the feed-point
the radiation. Intensity is maximum along the normal to the dipole axis
