Which of the following statements about antenna polarization are true? (Choose all that apply.)
A.
An antenna emits electromagnetic waves to the surrounding space. The electric field vector follows a regular rhythm of changes.
B.
Antenna polarization refers to the magnetic field vector generated when an antenna radiates power.
C.
If the electric field vector of the radio wave is perpendicular to the ground, the radio wave is a vertical polarized wave.
D.
A dual-polarized antenna integrates two antennas whose polarization directions are perpendicular to each other to maximize the diversity gains and save installation space.
Field Vector: The field vector (specifically the electric field vector) determines the polarization of the radio wave.
If the E-field vector is perpendicular to the ground, the radio wave is vertically polarized.
If the E-field vector is parallel to the ground (horizontal plane), the radio wave is horizontally polarized.
