Circular polarization

If the polarization of the receiving antenna is not the same as the polarization of the

incoming (incident) wave, the power extracted from the incoming signal is not maximum

because of the polarization loss. It is very important in a communication system to use

antenna with the same polarization and placed physically in such a way as to not change

their characteristics. If the antennas are linear polarized, do not place the two antennas

orthogonally relative to one another, if the antennas are circular polarized, use both

antennas or right polarized or left polarized.
