Huawei H12-311_V3.0 Exam - Topic 3 Question 66 Discussion

For the polarization of electromagnetic waves, which of the following descriptions is correct is (). (Select 3 Answers)
A) The antenna radiates electromagnetic waves to the surrounding space and C) If the electric field direction of the electric wave is perpendicular to the ground, we call it a vertically polarized wave and D) 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.
B) 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

I feel like option D might be tricky; I know matching polarizations is important, but I can't remember if they have to be the same for circular polarization.

I practiced a similar question about polarization, and I believe option C is right since vertical polarization means the electric field is perpendicular to the ground.

The key is understanding that the polarization refers to the direction of the electric field, not the magnetic field. I think I can eliminate a few of these options based on that.

Okay, let me think through this step-by-step. The question is asking about the correct descriptions of electromagnetic wave polarization, so I need to focus on the direction of the electric and magnetic fields.

I'm sure the correct answer is B, C, and D. The polarization of the antenna refers to the direction of the electric field, and the electric field changes according to a certain rule. Plus, circular polarization requires the transmitting and receiving antennas to have the same polarization direction.
