Question

Which of the following limit is correct for the polarization loss factor?

(a) 0≤PLF≤1

(b) -1≤PLF≤1

(c) -1≤PLF≤0

(d) 0≤PLF≤∞

The question was asked in unit test.

My doubt stems from Polarization Mismatch topic in portion Radiation, Baluns & Polarization of Antennas

Answer 1

Right choice is (a) 0≤PLF≤1

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

⇨ Max value of PLF = 1

⇨ Min value of PLF = 0

⇨ 0≤PLF≤1
