it is a expression of the orientation of the lines of electric flux in an electromagnetic field EM field. Polarization can be constant that is, existing in a particular orientation at all times, or it can rotate with each wave cycle.

The physical orientation of a wireless antenna corresponds to the polarization of the radio waves received or transmitted by that antenna.is an expression of the orientation of the lines of electric flux in an electromagnetic field (EM field). Polarization can be constant -- that is, existing in a particular orientation at all times, or it can rotate with each wave cycle.

The polarization that is used for cellular, PCS, and enhanced specialized mobile radio (ESMR) systems is primarily vertical. There are a few, rare instances in which the polarization is not vertical, for example, a polarization diversity antenna and the horizontal polarization antenna used for increased isolation for a control station with ESMR. However, the polarization is determined by the E field used, which, in almost all wireless communication systems, means that the polarization is vertical.

Polarization is important in wireless communications systems. The physical orientation of a wireless antenna corresponds to the polarization of the radio waves received or transmitted by that antenna. Thus, a vertical antenna receives and emits vertically polarized waves, and a horizontal antenna receives or emits horizontally polarized waves. The best short-range communications is obtained when the transmitting and receiving (source and destination) antennas have the same polarization.
