Horizontal polarization vs Vertical polarization

This page Horizontal polarization vs Vertical polarization describes about polarization and mention difference between Horizontal polarization and Vertical polarization.

Horizontal polarization vs Vertical polarization

Orientation of electric and magnetic field vectors are very important in radio wave communication. The direction of electric field vector specifies polarization of the antenna. There are two types in linear polarization viz. horizontal and vertical.

In the horizontal polarization, electric field vector of EM(electro-magnetic) wave is parallel to the earth.This is generated by having antennas horizontal to the earth. The same is explained in the figure by showing electric field in the direction of propagation.

In the vertical polarization, electric field vector of EM(electro-magnetic) wave is perpendicular to the earth.This is generated by having antennas vertical to the earth. The same is explained in the figure by showing electric field in the perpendicular direction of propagation.

In order to make communication link work effectively, both transmitting and receiving antennas should be in the same polarization.

Usage of polarization:
•  It allows the frequency re-use.
•  Linear polarization is used on domestic and non-intelsat type of satellites.
