5 reasons why corrugated horn antennas are more efficient than conventional horn antennas
Corrugated horn antennas achieve 20-30dB side lobe suppression and 98% aperture efficiency versus 50-60% in conventional horns. Their grooved inner walls (λ/4 depth) enable hybrid mode operation, reducing spillover loss by 3-5dB across 1.5:1 bandwidths. The corrugations create symmetrical E/H-plane patterns (±0.5dB variation) ideal for satellite feeds, outperforming smooth-wall horns’ 10-15dB cross-polarization levels at 10-30GHz […]
