Unveiling the Power of Panel Antennas: A Comprehensive Guide

Understanding Key Parameters

1. Frequency Range

• 4G/LTE Systems: 2300–2700 MHz antennas (e.g., GL-DY2327V9014) ensure backward compatibility and cost-effective upgrades.

• 5G NR Deployments: 3300–3800 MHz antennas (e.g., GL-DY3338V9016) align with 3GPP n78/n77 bands for enhanced throughput and low latency.

2. Gain (dBi)

• 14–16 dBi: Higher gain antennas focus energy into narrower beams, improving EIRP (Effective Isotropic Radiated Power) for long-range backhaul or sparse rural coverage.

• Trade-offs: Increased gain reduces vertical beamwidth (e.g., 7.5° vs. 15°), necessitating precise alignment for sectorized networks.

3. Polarization

• Vertical Polarization: Dominates cellular systems due to compatibility with handheld devices and reduced ground reflection losses. Cross-polarization designs are rare in standard sector antennas but critical for MIMO configurations.

4. VSWR (Voltage Standing Wave Ratio)

• ≤1.5: Industry benchmark for minimizing reflected power (<4% loss), ensuring efficient RF energy transfer. Values exceeding 2.0 degrade SNR and throughput.

5. Beamwidth Optimization

• Horizontal (90°): Ideal for 120° sectorization in tri-sector base stations.

• Vertical (7.5°–30°): Narrower beams (e.g., 7.5°) suit long-range point-to-multipoint links; wider beams (15°–30°) enhance indoor penetration or dense urban microcells.

Material Engineering for Durability

1. Radome Construction

• UPVC (Unplasticized PVC): Selected for its dielectric stability (εᵣ ≈ 2.9–3.4), UV resistance, and operational resilience across -40°C to +65°C. Superior to ABS in hydrolytic degradation resistance.

• IP67 Compliance: Ensures dust/water ingress protection for outdoor mmWave and sub-6 GHz deployments.

2. Structural Integrity

• Aluminum Alloy Frame: Provides EMI shielding and mechanical rigidity, rated for wind loads up to 60 m/s (216 km/h).

• Corrosion-Resistant Fasteners: Stainless steel brackets prevent galvanic corrosion in coastal or industrial environments.
