← ScienceWhich phenomenon causes signal fading when polarized radio waves encounter misaligned receiver antennas?
A)Polarization mismatch signal loss✓
B)Refractive index signal cancellation
C)Doppler shift frequency modulation
D)Atmospheric attenuation signal reflection
💡 Explanation
Signal fading occurs because polarization mismatch causes inefficient energy transfer, reducing the received signal strength. This is due to the difference between the polarization axes of the transmitting and receiving antennas; therefore, polarized signal losses occur in the receiver, rather than atmospheric effects interfering.
