Waveguide-fed Pyramidal Corrugated Horn
 |
Image of the Corrugated pyramidal horn antenna. |
The Corrugated pyramidal horn is a variation of the standard Pyramidal horn. The addition of corrugations to the standard pyramidal horn
improves the back and sidelobe level performance. Higher back- and sidelobe levels result from energy diffracted by the edges perpendicular to the E-plane.
Corrugations in the E-plane edges of the corrugated horn control the illumination of the diffracting edges, suppressing unwanted back- and sidelobes.
