Antenna Polarization

Definition: Antenna Polarization is the term used in correspondence with the electromagnetic wave radiated through it. It is defined as the orientation of the electric field vector of the radiated electromagnetic wave by the antenna with a negligible amount of losses. Polarization of the antenna is regarded as a crucial parameter and must be considered …
