Question

Which of the following is best described by the polarization loss factor?

(a) Power loss due to mismatch

(b) Height of antenna

(c) Directivity

(d) Power gain

This question was addressed to me in an international level competition.

My question is from Polarization Mismatch topic in section Radiation, Baluns & Polarization of Antennas

Answer 1

Correct answer is (a) Power loss due to mismatch

To elaborate: The polarization loss factor describes the power loss due to polarization mismatch. The polarization loss factor due to mismatch if the two linear polarized antennas are rotated by an angle ∅ is given by PLF =cos^2∅.
