right hand circular polarisation (RHCP)

Electromagnetic waves propagate in space unipolarized, they have no fixed plane of oscillation. It is only through polarisation

that a specific plane of oscillation is determined. Polarization can be horizontal, vertical or in any other direction, but it is also possible to influence polarization in such a way that the wave propagates

inspace in a circular manner

.In circular polarization, which is produced

withhelical antennas, the field strength vector, which is perpendicular to the direction of propagation, rotates to the right or left


Depending on whether

theelectromagnetic wave

rotatesclockwise or counterclockwise when viewed from the helical antenna, it is referred to as Right Hand Circular Polarization (RHCP) or Left Hand

Circular Polarization(LHCP).

Circular polarization is generated by two antennas whose antenna elements are at right angles to each other and which are driven with two transmit signals that are 90° out of phase. With circular polarization, atmospheric interference can be suppressed.
