The Corrugated Horn Antenna is a specialized microwave antenna featuring periodic corrugations (grooves) along its inner wall surface. These corrugations function as surface impedance matching elements, effectively suppressing transverse surface currents and enabling exceptional electromagnetic performance.

Key Technical Features:

Ultra-Low Sidelobes: Typically below -30 dB through surface current control
High Polarization Purity: Cross-polarization discrimination better than -40 dB
Symmetrical Radiation Pattern: Nearly identical E- and H-plane beam patterns
Stable Phase Center: Minimal phase center variation across frequency band
Wide Bandwidth Capability: Typically operates at 1.5:1 frequency ratios

Primary Applications:

Satellite communication feed systems
Radio astronomy telescopes and receivers
High-precision metrology systems
Microwave imaging and remote sensing
High-performance radar systems

The corrugated structure enables this antenna to achieve performance characteristics unattainable by conventional smooth-wall horns, particularly in applications requiring precise wavefront control and minimal spurious radiation.
