Circular Polarized Horn Antenna

Circular Polarized Horn Antenna

Circularly polarised horn antenna is a special kind of antenna which is mainly used in wireless communication system. It combines the features of high gain and circular polarisation of horn antenna, which can effectively improve the anti-interference ability and transmission distance of communication system.

1. Principle of operation: A circularly polarised horn antenna transmits and receives signals by rotating the electric field vector of an electromagnetic wave in a vertical plane. This rotation can be left or right depending on the design. Circular polarisation significantly reduces polarisation mismatch losses due to reflections, thus improving communication quality.

2. Application Scenarios: These antennas are widely used in satellite communications, radar systems, radio navigation, and wireless communications that require high reliability and anti-interference capability. For example, in satellite communications, the use of circular polarisation can reduce signal attenuation caused by atmospheric refraction and ground reflection.
