Broadband Dual-Polarized Horn Antenna is a high-performance antenna system capable of operating in two orthogonal polarizations (typically ±45° linear or RHCP/LHCP circular) across a wide frequency range (e.g., 2:1 bandwidth such as 18-40GHz). By incorporating an Orthogonal Mode Transducer (OMT) and an optimized multi-segment horn structure, it delivers high port isolation (>30dB), stable gain (12-20dBi), and low VSWR (<1.5) while maintaining excellent polarization purity (axial ratio <3dB for circular polarization). These antennas support polarization diversity and MIMO configurations, making them ideal for 5G millimeter-wave base stations, satellite communications, EMC testing, and radar cross-section measurements where wide bandwidth and dual-channel operation are essential.
