Left Hand Circular (LHCP)
Full Name
Left Hand Circular Polarisation
Definition
An antenna is classified as Left Hand Circularly Polarised if the driven element radiates an electromagnetic wave in which either the electric or the magnetic vector executes a counterclockwise circle perpendicular to the path of propagation with a frequency equal to that of the wave.
The term hand is used as it refers to the formation of a "thumbs up" with a persons left hand, where the thumb indicates the direction of wave propagation, and the fingers curl in the direction of the circular rotation.
