DUAL-POLARIZED BROADBAND HORN ANTENNAS
Quad-Ridged Broadband Horn Antennas (HQ)
The HQ Series Quad-Ridged Broadband Horn Antennas feature an advanced four-ridge waveguide architecture engineered for dual-linear polarization and multi-octave continuous operation spanning frequencies from 200 MHz up to 40 GHz.
Designed for simultaneous horizontal and vertical polarization measurements without physical antenna rotation, the HQ Series is widely used in antenna pattern measurement, electromagnetic compatibility (EMC/EMI) testing, cross-polarization isolation analysis, and ultra-wideband radar detection.
*Custom frequency tuning, high port isolation options, and phase-matched feed assemblies are available upon request.
⚡ Next-Gen Engineering Highlights
Dual Linear Polarization
Four-ridge waveguide architecture allows simultaneous horizontal and vertical polarization measurement with dual RF ports.
Ultra-Wide Spectrum
Continuous multi-octave frequency coverage from 200 MHz to 40 GHz without band switching for fast sweep testing.
High Port Isolation
Precision internal ridge symmetry guarantees exceptional isolation (>30 dB) between orthogonal polarization channels.
Precision Aluminum Build
Aircraft-grade CNC machined aluminum construction ensures structural stability, repeatability, and long-term calibration accuracy.
