Circular Polarized Antennas
|
In circular polarized antennas, the plane of polarization rotates in a circle making one complete revolution during one period of the wave. A circular polarized wave radiates energy in both the horizontal and vertical planes and all planes in between. Circular polarization occurs where the horizontal and vertical components are equal but differ in phase by 90 degrees. If the rotation is clockwise looking in the direction of propagation, the sense is called right-hand-circular polarization. If the rotation is counterclockwise, the sense is called left-hand-circular polarization. Circular polarization is most often used on satellite communications. Circular polarized antennas include elliptical, right-hand-circular polarization (RHCP) and left-hand-circular polarization (LHCP). Products & Services

Circular polarizers block all photons rotating in one direction while allowing those rotating in the opposite direction to pass. They are assemblies that consist of a linear polarizer and a wave retarder, usually a quarter waveplate or half waveplate.

Specialty Optical Polarizers use the optical properties of a medium to alter the polarization of light. This category includes radial polarizers, azimuthal polarizers, elliptical polarizers, etc.
