5g outdoor wifi antenna high gain

5G Outdoor WiFi High-Gain Antenna Technical Specification
1. Overview
The 5G outdoor high-gain antenna is designed for long-range wireless communication in sub-6 GHz bands (e.g., 3.3–4.8 GHz) and mmWave bands (24–48 GHz), optimized for 5G NR, Wi-Fi 6E, and IoT applications. It delivers superior directional gain (≥15 dBi) to extend coverage in challenging environments such as urban canyons, stadiums, or industrial zones.

2. Key Technical Specifications

| Polarization | Linear (Vertical/Horizontal) or Circular (for mmWave bands) |
| Beamwidth | 3–15° (narrow beam for long-distance focus) |
| 导体材料 | Oxygen-free copper (low loss, high conductivity) or aluminum alloy (lightweight). |
| Enclosure | Weatherproof (IP67/IP68 rated) – suitable for extreme temperatures (-40°C to +85°C) and humidity. |
| Mounting Options | Ground Mount, Pole Mount, or Wall Mount – includes adjustable brackets and clamps. |

4. Design Considerations
4.1 Frequency Band Selection
Sub-6 GHz: Better penetration through obstacles; suitable for indoor/outdoor bridging.
mmWave: Ultra-high bandwidth (up to 10 Gbps) but limited range; ideal for low-latency applications (e.g., AR/VR, autonomous vehicles).
4.2 Gain Optimization
Law of Reflection: Use parabolic reflectors to focus signals.
Array Design: Multiple antenna elements (e.g., 4×4 MIMO array) increase gain and spatial resolution.
4.3 Environmental Adaptability
Weatherproofing: Apply silicone sealants to connectors and use UV-resistant coatings.
Heat Dissipation: Aluminum radiators or heat sinks prevent overheating in high-power scenarios.
4.4 Impedance Matching
Use LC/π-type matching networks or distributed matching techniques to minimize signal loss.
Simulation Tools: HFSS or CST Microwave Studio for optimizing antenna performance.
5. Typical Applications
5G Network Deployment
Coverage extension for mmWave small cells in urban areas.
Public WiFi Hotspots
High-density coverage in stadiums, airports, or convention centers.
Industrial IoT
Reliable long-range communication for sensors and actuators in factories.
Military/Defense
Secure point-to-point links with low probability of intercept (LPIT).
Satellite Communication
Ground station antenna for Earth observation or satellite internet (e.g., Starlink).
