Description

A wideband horn antenna is a versatile, high-performance antenna designed to operate over a broad frequency range—making it a staple in RF testing, EMC compliance, and broadband communication systems. 📡 Key Characteristics - Frequency Range: Typically from 700 MHz to 50 GHz, depending on design (e.g., double-ridged, pyramidal, or conical horns) - Gain: - Standard gain: 10–20 dBi - High gain models: >22 dBi - Polarization: Usually linear; some models support dual polarization - VSWR: Often < 1.5:1 across the band for efficient power transfer - Power Handling: Up to several hundred watts (e.g., 300–400 W CW) 🛠️ Construction & Mounting - Materials: Precision-machined aluminum with corrosion-resistant coatings - Mounting: Tripod, bracket, or test fixture compatible - Connectors: N-type, SMA, or waveguide flanges depending on frequency 🧪 Applications - EMC/EMI Testing: Ideal for radiated immunity and emissions testing (e.g., FCC, CE, MIL-STD-461) - Antenna Calibration: Used as reference antennas due to predictable gain and pattern - 5G & Radar: Suitable for mmWave testing and beamforming validation - Scientific Research: Anechoic chamber measurements, shielding effectiveness, and site surveys For example, the Com-Power AH-118 covers 700 MHz to 18 GHz, supports up to 300 W, and is individually calibrated to ANSI C63.5 standards. Meanwhile, Steatite’s wideband horn range spans 170 MHz to 50 GHz, offering both standard and custom designs. If you're planning to use one for EMC testing or antenna characterization, I can help you compare models or match it with the right preamp and test setup. Want to explore that?
