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.

The combination of COMSOL® products required to model your application depends on the physics interfaces that define it. Particular physics interfaces may be common to several products (see the Specification Chart for more details). To determine the right combination of products for your project, you should evaluate all of your needs in light of each product\'s capabilities, consultation with the COMSOL Sales and Support teams, and the use of an evaluation license.
