2-Port Directional Antenna

High-Gain Panel Antenna for 5 GHz WLAN and WiFi Networks

The 2-Port Directional Antenna is a dual-port panel antenna designed for point-to-point and point-to-multipoint wireless data transmission across the 4900–6100 MHz band. With a maximum gain of 23 dBi and dual vertical/horizontal polarization, this antenna delivers focused directional coverage for enterprise WLAN, WiFi 5, and licensed spectrum applications requiring high isolation and stable performance in outdoor environments.

Frequency Coverage and Gain Performance

Operating across three sub-bands—4900–5150 MHz, 5150–5500 MHz, and 5500–6100 MHz—the antenna provides variable gain performance tailored to each band. Gain ranges from 20.5 dBi in the lower band to 23 dBi in the upper band, with horizontal and vertical 3 dB beamwidths of 10–12° depending on frequency. This narrow beamwidth concentrates RF energy in the direction of the target access point or client device, reducing interference and improving link reliability in dense deployments.

Port Isolation and Impedance Matching

The antenna achieves ≥28 dB front-to-back ratio and ≥28 dB port-to-port isolation, critical for MIMO and diversity systems where cross-coupling between ports degrades throughput. Dual N-female connectors on the rear panel support standard 50 Ω coaxial feeds. VSWR ≤2.0 across the operating band ensures efficient power transfer and minimal reflected energy, while the 50 W maximum power rating accommodates both low-power CPE and higher-power base station amplifiers.

Rugged Outdoor Construction and Environmental Compliance

Built for harsh outdoor deployment, the antenna features an ABS radome in white, IP67 waterproof sealing, and salt-spray resistance (JM-TA standard) for coastal and corrosive environments. Operating temperature range of −40 °C to +60 °C supports arctic and tropical installations. The compact panel measures 315 × 315 × 15 mm and weighs 1 kg, mounting securely to poles 30–50 mm in diameter via the rear bracket. Wind resistance rated to 55 m/s (≈198 km/h) ensures structural integrity in severe weather.

Lightning and Grounding Protection

DC ground lightning protection is integrated into the connector assembly, reducing the risk of transient damage during electrical storms. This passive grounding path is essential for rooftop and tower-mounted installations where lightning strike risk is elevated.

Deployment Scenarios and Customer Applications

Enterprise Campus and Outdoor WiFi Networks

System integrators and network operators deploy this antenna in point-to-point bridge links connecting campus buildings, warehouses, or outdoor venues. The high gain and narrow beamwidth minimize interference from adjacent access points and reduce power consumption on battery-powered clients, extending coverage range in open-air deployments.

Licensed Spectrum and Fixed Wireless Access

Operators of licensed 5 GHz bands (such as UNII-3 and UNII-4 in North America) use dual-port directional antennas for fixed wireless access (FWA) and backhaul links. The port isolation and front-to-back ratio support MIMO transmission and reduce co-channel interference in frequency-reuse networks.

Base Station and Distributed Antenna Systems

Telecom equipment manufacturers and DAS integrators incorporate this antenna into indoor/outdoor remote radio heads and sector antennas for small-cell and macro-cell coverage. The compact form factor and dual-port design simplify integration into multi-sector base station arrays.
