Double‑Ridged Guide Antenna : 3117 | ETS-Lindgren

The ETS‑Lindgren Model 3117 Double‑Ridged Waveguide Horn Antenna (ref. 400205) delivers uniform illumination and accurate gain over a broad frequency from 1 GHz to 18 GHz. It corrects common upper‑band gain drop-offs in ridge antennas while maintaining linear polarization.

Benefits :

• Ultra‑broadband coverage from 1 GHz to 18 GHz
• Stable gain and antenna factor, essential for precise measurements
• Low VSWR ensures efficient power transfer
• Supports moderate power input: 300 W continuous, 500 W peak
• Compact and lightweight for both chamber and field use

Key Features :

• Frequency range: 1 GHz – 18 GHz
• VSWR: ≤ 3.5:1 max, typically < 2:1 above 1.5 GHz
• Power handling: 300 W continuous, 500 W peak
• Connector: Type N (female)
• Polarization: Linear
• Radiation pattern: Single main lobe over full band
• Calibration: Individual at 1 m with signed certificate
• Dimensions: ~15.5 cm tall × ~17.5 cm wide; weight ~1.1 kg
• Mounting: Bracket with ¼‑20 tripod thread or rear stinger mount

Typical Applications :

• Automated swept-frequency EMC testing
• Radiated immunity and emissions measurements in chambers and open field

Further Information :

• Engineered to correct gain roll-off at upper frequencies
• Individually calibrated in accredited lab for traceable measurement
• Portable design with durable powder-coated aluminum housing
