Core Advantages

✅ Wide Frequency Coverage for Multi-Standard Terminal Testing

The 2.2–7 GHz operating range covers major ISM and mobile communication bands, including 5G Sub-6 GHz, Wi-Fi 2.4 GHz / 5 GHz, and Bluetooth. A single antenna can support OTA radiated performance testing for multiple categories of wireless terminals.

✅ Standard Dual-Polarized Horn Structure

The antenna adopts a classic square horn design with high manufacturing consistency and stable radiation patterns, making it suitable for use as a standard reference transmit/receive antenna in RF and OTA anechoic chambers.

Two orthogonal RF ports support independent horizontal and vertical linear polarization operation.

✅ Excellent Polarization Isolation

With port isolation of ≥ 25 dB and cross-polarization discrimination of ≥ 20 dB, the antenna provides low coupling between polarization channels. It is suitable for channel isolation and polarization-related testing of MIMO multi-antenna devices and diversity reception systems.

✅ Machined Aluminum Alloy Structure

The integrated aluminum alloy construction provides low RF loss, high mechanical strength, and excellent structural stability. It is suitable for long-duration continuous testing in RF/OTA chambers and supports flexible integration with mounting fixtures and antenna positioning systems.

✅ Stable Directional Radiation Performance

With a VSWR of ≤ 2 and a rated gain of 12.9 dBi, the antenna provides stable directional radiation and beam characteristics, supporting consistent signal quality and repeatable OTA measurements such as TRP and TIS testing.
