Description

A conical horn antenna is a type of microwave antenna that features a circular waveguide flared into a cone, making it ideal for applications requiring circular symmetry and broad radiation patterns. 📡 Key Characteristics - Shape: Cone-shaped with a circular aperture - Polarization: Typically supports circular or linear polarization - Frequency Range: Operates in microwave bands, often from 8 GHz to 40 GHz, depending on the waveguide size - Gain: Varies with flare angle and aperture size; common values are 10–25 dBi - VSWR: Low (around 1.3:1), ensuring efficient energy transfer - Beamwidth: Moderate, typically 20°–60°, depending on design 🛠️ Design & Construction - Waveguide-fed: Uses a circular waveguide (e.g., WR-90, WR-75) as the feed - Material: Usually aluminum or brass, sometimes with a protective coating - Flange: Standard circular waveguide flanges like UG-39/U or UG-595/U - Precision Machining: Ensures phase consistency and low sidelobes 🚀 Applications - Radar calibration and gain reference - Antenna pattern measurements - EMC/EMI testing - Field propagation studies - Transmitter power monitoring
