The Broadband Horn Antenna is a specialized microwave antenna designed to operate over exceptionally wide frequency ranges, typically achieving 2:1 or greater bandwidth ratios. Through sophisticated flare profile engineering – employing exponential or corrugated designs – it maintains stable radiation characteristics across its entire operating band.

Key Technical Advantages:

Multi-Octave Bandwidth: Seamless operation across wide frequency spans (e.g., 1-18 GHz)
Stable Gain Performance: Typically 10-25 dBi with minimal variation across band
Superior Impedance Matching: VSWR generally below 1.5:1 throughout operating range
High Power Capacity: Capable of handling hundreds of watts average power

Primary Applications:

EMC/EMI compliance testing and measurements
Radar cross-section calibration and measurements
Antenna pattern measurement systems
Wideband communication and electronic warfare systems

The antenna’s broadband capability eliminates the need for multiple narrowband antennas in testing scenarios, significantly improving measurement efficiency. Its combination of wide frequency coverage, reliable performance, and robust construction makes it invaluable for modern RF testing and measurement applications.
