Q21. For the polarization of electromagnetic waves, which of the following descriptions is correct is (). (Select 3 Answers)

The antenna radiates electromagnetic waves to the surrounding space

The polarization of the antenna refers to the direction of the magnetic field strength formed when the antenna radiates
, The direction of the electric field changes according to a certain rule

If the electric field direction of the electric wave is perpendicular to the ground, we call it a vertically polarized wave

If the transmitting antenna is circularly polarized, the receiving antenna must also be circularly polarized, and the polarization direction of the two must be the same.
