✅ Wide Millimeter-Wave Frequency Coverage
The antenna operates from 18 GHz to 50 GHz, covering major 5G millimeter-wave bands such as 24 GHz, 28 GHz, and 39 GHz. It is suitable for RF and OTA testing of millimeter-wave communication terminals, automotive radar systems, and high-speed short-range wireless modules.
✅ High Port Isolation and Excellent Polarization Purity
The antenna adopts an integrated orthogonal dual-polarized waveguide structure, providing port isolation of ≥ 27 dB and cross-polarization discrimination of ≥ 20 dB.
Low coupling between polarization channels makes it suitable for OTA performance evaluation of millimeter-wave MIMO devices, phased-array antennas, and dual-polarized wireless terminals.
✅ Precision-Machined Aluminum Alloy Construction
The antenna features an integrated precision-machined aluminum alloy structure with low RF loss and stable radiation characteristics at millimeter-wave frequencies. Its robust mechanical design supports long-duration continuous testing in RF and OTA anechoic chambers.
✅ Stable RF Matching and Directional Radiation Performance
With a VSWR of ≤ 2 and a rated gain of 15 dBi, the antenna provides stable impedance matching, focused directional radiation, and repeatable measurement performance for far-field OTA and compact antenna test range applications.
✅ Compact Square Aperture Design
The antenna features a compact 40 mm × 40 mm square aperture, offering a smaller footprint than the previous 43.2 mm model. Its compact form factor facilitates multi-antenna array configurations and flexible integration with mounting fixtures and positioning systems.
