Why Circular Polarization Antenna? Polarization Types FRC An antenna is a transducer that converts radio frequency (RF) electric current to electromagnetic waves that are then radiated into space. Antenna polarization is an important consideration when selecting and installing antennas. Most wireless communication systems use either linear (vertical, horizontal) or circular polarization. Knowing the difference between polarizations can help maximize system performance for the user. Linear Polarization: An antenna is vertically linear polarized when its electric field is perpendicular to the Earth’s surface. An example of a vertical antenna is a broadcast tower for AM radio or the whip antenna on an automobile. Horizontally linear polarized antennas have their electric field parallel to the Earth's surface. For example, television transmissions in the USA use horizontal polarization. Thus, TV antennas are horizontally-oriented.
