In millimeter-wave communication systems, antenna gain is a decisive factor influencing signal reach, quality, and system efficiency. Standard gain horns-such as 10dB and 25dB models-serve distinct roles:
10dB antennas offer wide beamwidth (55°–85°) and compact dimensions (e.g., 110 mm length at 6–18 GHz), ideal for near-field testing and short-range links.
25dB antennas provide focused beams (<5° beamwidth) and extended range, critical for long-distance backhaul (e.g., 50 km+ with 32dBi antennas) and radar systems. However, they require precision engineering to manage phase distortion at high frequencies.
Key Applications & Technical Trade-offs
When to Choose 10dB Gain:
Portable & IoT Devices: Compact designs (e.g., 30 mm length for 60–90 GHz) minimize footprint while maintaining adequate signal coverage.
Cost-Sensitive Projects: Aluminum construction reduces costs by 40% versus copper-based high-gain models.
Broad-Angle Coverage: Omnidirectional patterns suit dense urban 5G small cells.
When 25dB Gain Excels:
Long-Range Backhaul: Achieves 50 km links in 75–110 GHz bands with ≤0.5 dB calibration accuracy.
Radar/Satellite Systems: High aperture efficiency (e.g., 0.511 phase control) minimizes signal loss in aerospace applications.
EMC Testing: Enhanced directionality isolates interference in noisy environments.
Customization Challenges in High-Gain Designs
25dB antennas demand rigorous manufacturing control:
Material Science: Copper bodies (e.g., HD-2600SGAH25) reduce thermal drift in 217–330 GHz operations.
Phase Alignment: Tolerance thresholds under ±0.05 mm prevent gain saturation at >30 GHz frequencies.
Calibration: Factory-graded gain calibration (e.g., ±0.5 dB accuracy) requires anechoic chamber testing.
Selecting a Microwave Antenna Factory
Specialized factories combine four capabilities for custom orders:
Bandwidth-Gain Flexibility: Factories like Mi-Wave offer 10–25dB gains across 0.32–300 GHz, including THz extensions.
Material Expertise: Copper electroplating for >25dB designs versus aluminum for lightweight 10dB units.
Certified Precision: ISO 9001/QC080000 compliance ensures millimeter-wave tolerances.
Application Engineering: Custom flanges (FUGP/FBP) and feeds (waveguide/coaxial) for radar, 5G, or IoT integration.
Conclusion: Match Gain to Function
While 10dB antennas excel in cost and flexibility, 25dB variants unlock long-range precision-if engineered correctly. Partner with a Microwave Antenna factory that validates electrical specs (VSWR ≤1.5, isolation ≥20dB) and environmental resilience (IP65, -30°C–80°C)36. For 5G backhaul or satellite terminals, prioritize factories with proven 25dB calibration expertise.
