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.

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).
