Broadband Horn Antenna is a type of directional radiating antenna based on a tapered waveguide structure. It achieves multi-octave broadband operation (e.g., 2:1 frequency ratio, typically 18-40GHz) through a precisely designed horn aperture and flare angle. Its core advantages include stable gain across the entire frequency band (fluctuation <3dB), low Voltage Standing Wave Ratio (VSWR <1.5), and high power-handling capacity (average power >500W), while maintaining low sidelobe levels (<-20dB) and high polarization purity. It is primarily used in electromagnetic compatibility (EMC) testing, antenna calibration, millimeter-wave communication systems, and radar target scattering measurement applications, making it an indispensable broadband reference antenna in microwave testing and communication systems.
