Corrugated Circular Horn Antenna
Application ID: 15677
Corrugated circular aperture (conical) horn antennas are popularly used as feed horns for dish reflector antennas due to their low side lobe and cross-polarization level. The excited TE mode from a circular waveguide passes along the corrugated inner surface of a circular horn antenna, where a TM mode is also generated. When combined, these two modes give lower cross polarization at the antenna aperture. By using this application, the antenna radiation characteristics and aperture cross-polarization ratio can be improved by modifying the geometry of the antenna.
