* '''Antenna polarization''' is the direction in which electric field oscillates while it propagates through environment. It is important to match broadcasting and receiving antennas polarization: it must be same polarity. In this way the maximum signal is obtained. WiFi antennas are almost always vertically polarized, while mobile antennas are either vertically polarized or cross polarized | * '''Antenna polarization''' is the direction in which electric field oscillates while it propagates through environment.
