Dual-Band 4x4 MIMO Wi-Fi Antenna (2.4 / 5 GHz)

Specialized dual-beam antenna designed for warehouse and industrial Wi-Fi environments

This antenna is compatible with modern Wi-Fi standards including 802.11a/b/g/n/ac/ax and is designed for challenging indoor environments such as warehouses and production facilities.

Proper antenna selection and placement are critical for achieving optimal wireless performance. A complete antenna system includes not only the antenna itself, but also mounting hardware, connectors, cabling and, in some cases, lightning protection.

Dual Radiation Pattern – Designed for Warehouses

The antenna generates two radiation beams:

• Primary beam: directed forward with a gain of approximately 6–7 dBi
• Secondary beam: slightly tilted upward (~10%) with a similar gain

This design is optimized for warehouse environments where ceilings are typically made of metal or concrete.

The primary beam provides direct coverage in front of the antenna, while the secondary beam reflects from the ceiling and helps illuminate areas between obstacles such as storage racks and goods.

This approach improves coverage in areas where direct signal propagation is limited.

Optimized for Modern Wi-Fi Technologies

The antenna is designed for use with modern MU-MIMO and OFDMA-based systems, including Wi-Fi 5 (Wave 2), Wi-Fi 6 and Wi-Fi 7.

Specially designed radiating elements with low self-capacitance ensure proper operation with high-order modulation schemes such as:

• 256-QAM
• 1024-QAM (Wi-Fi 6)
• 4096-QAM (Wi-Fi 7)

Low self-capacitance helps maintain signal integrity and reduces unwanted reflections and parasitic currents.

Application Environments

• warehouses and logistics centers
• production facilities
• indoor industrial environments

Note: This antenna is intended for indoor use. It is not recommended for open outdoor spaces, as the secondary beam relies on ceiling reflections for proper operation.

MIMO and Multipath Performance

MIMO antenna systems are designed to take advantage of multipath propagation, which is common in environments with reflective surfaces such as metal structures.

Instead of treating reflections as a problem, modern Wi-Fi systems use them to improve signal reliability, increase throughput and enhance overall network performance.

By using multiple antennas with spatial and polarization diversity, the system can combine multiple signal paths to achieve better performance than a single-antenna solution.

Summary

This antenna is specifically designed for structured indoor environments where reflections can be used to improve coverage rather than degrade it.

It is a practical solution for building stable and predictable Wi-Fi networks in warehouses and industrial facilities.
