5G High Gain Directional Antenna

5G High Gain Directional Antenna Technical Specification
1. Overview
The 5G high-gain directional antenna is designed to deliver ultra-high directional radiation patterns (≥15 dBi) in sub-6 GHz and mmWave bands, enabling long-range, low-latency communication for mission-critical applications such as 5G NR, satellite communication, radar, and IoT. It minimizes interference and optimizes signal focus for dense urban environments or point-to-point links.

2. Key Technical Specifications

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
