Open Boundary Quad‑Ridged Horn Antenna : 3164-06 | ETS-Lindgren

The ETS‑Lindgren Model 3164‑06 Open Boundary Quad‑Ridged Horn Antenna features a unique open-boundary design, combining two orthogonal double‑ridged waveguide antennas. It offers broadband performance from 400 MHz to 6 GHz with both linear and circular (with hybrid) dual-polarized capability.

Benefits :

• Wide frequency coverage from 400 MHz to 6 GHz
• Dual linear polarization enables simultaneous orthogonal measurements
• Compact, lightweight design—ideal for tripod or wall mounting
• Flat gain characteristics over most of the upper two-thirds of the band

Key Features :

• Frequency range: 400 MHz – 6 GHz
• VSWR (avg/max): ~1.75:1 average, ≤ 5:1 maximum
• Maximum continuous power: 50 W at 400 MHz
• Impedance: 50 Ω
• Connector: Two SMA female inputs
• Cross‑polarization isolation: > 25 dB
• Polarization: Dual linear (circular with hybrid)
• Physical dimensions: ~51.4 cm length × 50 cm width × 50 cm height; weight ~9.3 kg
• Mounting: Tripod bracket or wall flange

Typical Applications :

• OTA wireless device testing (cellular, Wi‑Fi, GPS, UWB)
• Dual-polarization EMC measurements across broad frequency span

Further Information :

• Open-boundary architecture reduces size and improves pattern stability compared to enclosed quad-ridged horns
• No mechanical polarization switching needed thanks to dual orthogonal feeds
• Suitable for both chamber and wall-mounted setups
