Circular Polarisation

Circular polarization, also known as circular polarization, is a concept in electromagnetism theory that is used in various areas of communication technology. In contrast to linear polarization, in which the direction of oscillation of the electromagnetic wave lies in one plane, the plane of oscillation in circular polarization rotates continuously in a clockwise or counterclockwise direction.

This special form of polarization offers a number of advantages in wireless communication, especially when transmitting signals over long distances or in environments with many obstacles. Circular polarization enables better signal penetration and reduces the effects of multipath signals, resulting in improved transmission quality and increased range.

A common application of circular polarization is in satellite communications, where signals need to be transmitted between satellites and ground stations over long distances. By using circularly polarized antennas, the efficiency and reliability of communication can be improved, even under difficult atmospheric conditions.

In addition, circular polarization is also used in other areas such as radar, RFID systems, wireless networks and wireless microphone systems. In these applications, it enables more precise signal detection, better suppression of interference and higher immunity to external influences such as interference and signal attenuation.

Overall, circular polarization plays a crucial role in modern communication technology and helps to improve the performance and reliability of wireless transmission systems. Its understanding and application are therefore of great importance for the development and optimization of wireless communication networks in various fields.
