OPEN BOUNDARY BROADBAND HORN ANTENNAS
Open Boundary Double-Ridge Horn Antennas (HB)
The HB Series Open Boundary Double-Ridge Horn Antennas feature an innovative open-structure flared waveguide architecture designed to significantly reduce overall weight and wind load resistance.
Engineered for multi-octave continuous operation spanning frequencies from 200 MHz up to 40 GHz, the HB Series provides exceptional directional gain (10–20 dBi), low VSWR, and superior electromagnetic stability for EMC/EMI radiated immunity testing, antenna measurement, and wireless R&D.
*Custom frequency tuning, phase-matched pairs, and high-power feed options are available upon request.
⚡ Next-Gen Engineering Highlights
Open Boundary Design
Specialized open-side profile reduces structural weight and aerodynamic wind resistance while minimizing cavity reflections.
Ultra-Wideband Spectrum
Continuous multi-octave coverage across 200 MHz to 40 GHz without band switching for efficient sweep testing.
High Gain & Low VSWR
Precision-contoured double ridges maintain typical VSWR < 1.5:1 with smooth gain characteristics from 10 dBi to 20 dBi.
Precision Aluminum Build
Aircraft-grade CNC machined aluminum construction guarantees high structural integrity and long-term calibration stability.
