Antenna Polarization | Polarisation Basics Tutorial |… Antenna polarisation basics. For the electromagnetic wave the polarization is effectively the plane in which the electric wave vibrates. This is important when looking at antennas because they are sensitive to polarisation, and generally only receive or transmit a signal with a particular polarization. circularly polarized antennas Linearly polarized antennas are commonly used in terrestrial wireless communications.For a linearly polarized antenna, the input impedance is usually the most sensitive parameter compared to other antenna parameters such as radiation patterns, gain and polarization.
