Polarization loss factor in dB when two linear polarized antennas are

1.	Polarization loss factor in dB when two linear polarized antennas are rotated by an angle 45° is ___(a) 3dB(b) -3dB(c) 0.5dB(d) -0.5dBThe question was posed to me by my college director while I was bunking the class.The question is from Polarization Mismatch in section Radiation, Baluns & Polarization of Antennas
Answer» The CORRECT CHOICE is (B) -3dB For 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∅. ⇨ PLF = cos^2∅=cos^2 45=0.5=-3dB.
