Question

What is the Polarization loss factor?

Answer 1

Electric and magnetic fields characterize electromagnetic (EM) waves. In a plane EM wave, the electric and magnetic fields are perpendicular to one other and the wave propagation direction. An EM wave's polarization is a phrase that indicates the direction of its electric field vector. Antennas are the device that converts signals traveling on a conductor to electromagnetic waves.

Complete answer:
In antenna-to-antenna communication, polarisation is a crucial concept. When there is an antenna mismatch, EM power is lost. Faulty transmission and poor signal reception are caused by a loss of EMpower. The polarization loss factor (PLF) is the amount of EMpower lost due to the polarization match. It is a measure of the percent loss of polarization of the transmission field vector into the receiving antenna polarization vector. Values of the loss factor range from zero to one.

Additional information:
The three types of polarisation are linear, circular, and elliptical. If the polarisation of the antennas does not match, signal reception is degraded, resulting in polarisation loss. If at the same linear polarization, transmitting and receiving antennas are rotated by an angle $\phi$ from each other, as the angle between the radiated fields becomes non-zero, polarization mismatch or polarisation loss would occur as a result of this.

Note:
The word power dissipation is commonly confused with PLF. Power dissipation is the amount of power lost in the antenna after reception or during radiation. PLF, on the other hand, is the power that the antenna does not acquire from the incident wave. It's also known as a multiplier since it determines how much of the incident power is collected by the receiving antenna.
