By the orientation of the electric field✓Ճիշտ պատասխան
By the orientation of the magnetic field
By the direction of radiation
Բացատրություն
An antenna's polarization is stated by how its radiated electric field is oriented, which follows the orientation of its radiating element. A horizontal wire dipole therefore radiates a horizontally polarized wave, and a vertical whip radiates a vertically polarized one.
