Description

A dual linear polarization horn antenna is a high-performance directional antenna designed to transmit and receive RF signals in two orthogonal linear polarizations—typically horizontal and vertical—simultaneously. This makes it especially valuable in MIMO systems, EMC testing, and polarization diversity applications. 📡 Key Features - Polarization: Dual linear (H/V), with ports isolated to prevent cross-talk - Frequency Range: Commonly spans from 1 GHz to 40 GHz, depending on design - Gain: Typically 8–20 dBi, increasing with frequency - VSWR: Often < 2:1 across the band - Impedance: 50 Ω - Isolation: >30 dB between ports is typical - Power Handling: High CW power capability (often >100 W) 🛠️ Construction & Design - Waveguide Feed: Two orthogonal feeds (often via orthomode transducer or dual probes) - Aperture: Rectangular or square, optimized for symmetrical beamwidths - Material: Precision-machined aluminum with corrosion-resistant finish - Mounting: Tripod or bench mountable; polarization easily switchable 🧪 Applications - EMC/EMI Testing: Radiated immunity and emissions testing with polarization diversity - Antenna Calibration: Reference antenna in anechoic chambers - 5G & MIMO Systems: Supports dual-polarized signal paths for throughput optimization - Radar & Remote Sensing: Enhances detection accuracy with polarization separation For a deeper dive, everything RF offers a great technical overview, and Anteral’s DLPLHA series showcases a compact lens horn design with high isolation and low VSWR. If you're planning to integrate one into a test setup or compare it with circular or single-polarized horns, I can help you evaluate beamwidth, gain flatness, or connector compatibility.
