Core Advantages

✅ Wide Frequency Coverage for Multi-Standard Testing

The 2.2–7 GHz operating range covers major wireless communication bands, including 5G Sub-6 GHz, Wi-Fi 2.4 GHz / 5 GHz, and Bluetooth. A single antenna can support RF and OTA testing of smartphones, IoT modules, and other wireless terminals across multiple communication standards.

✅ Open-Boundary Horn Structure with Optimized Radiation Performance

The antenna features an open-boundary horn design that helps improve aperture field uniformity and directional beam characteristics compared with conventional enclosed horn structures. It is suitable for use as a reference transmit/receive antenna in RF and OTA anechoic chambers.

✅ High-Isolation Dual-Polarized Design

Two independent orthogonal polarization ports provide port isolation of ≥ 25 dB and cross-polarization discrimination of ≥ 20 dB. The high polarization purity helps reduce polarization coupling during MIMO testing and improves the consistency of multi-antenna terminal measurements.

✅ Precision-Machined Aluminum Alloy Construction

The integrated aluminum alloy structure provides low RF loss, high mechanical stability, and reliable long-term operation. It is suitable for continuous testing applications in RF/OTA anechoic chambers, including 24/7 production environments.

✅ High-Gain Directional Radiation Performance

With a rated gain of 14 dBi and a VSWR of ≤ 2 across the specified operating range, the antenna provides focused directional radiation, stable signal quality, and repeatable measurement performance for OTA applications such as TRP and TIS testing.
