Unveiling the Power of Panel Antennas: A Comprehensive Guide


In the ever - evolving landscape of wireless communication, panel antennas have emerged as essential components for efficient signal transmission and reception. In this blog post, we'll delve into the world of panel antennas, exploring their key parameters, materials, application scenarios, and offering useful selection advice based on real - world product specifications.

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.

Application Scenarios

Panel antennas are widely used in several application scenarios. In 4G/LTE and 5G network systems, they are employed for sector coverage in base stations. For example, in urban areas where there is a high demand for mobile connectivity, these antennas can be installed on rooftops or tall structures to provide seamless coverage to a large number of users within a specific sector. They are also useful in suburban and rural areas to extend network coverage and improve signal strength in regions that may have been previously underserved.

In addition to cellular networks, panel antennas can be used in wireless local area networks (WLANs) in large buildings such as airports, shopping malls, and convention centers. Their directional nature allows for focused signal transmission, reducing interference and providing reliable wireless access to a large number of devices.

Making the Right Selection

When choosing a panel antenna, consider your specific requirements. If you are setting up a 4G/LTE network, a 2300 - 2700MHz antenna would be appropriate. For 5G deployments, opt for the 3300 - 3800MHz model.

If you need to cover a larger area or have better signal penetration, an antenna with a higher gain, like 16 dBi, is preferable. However, if you have limited installation space, a smaller - sized antenna with a relatively lower gain but suitable for your coverage needs may be more practical.

Also, take into account the environmental conditions. If the antenna will be installed in an area with extreme weather, ensure it has a robust construction and proper lightning protection, like the DC ground lightning protection featured in these models.

In conclusion, panel antennas are versatile and powerful tools in the wireless communication arsenal. By understanding their parameters, materials, application scenarios, and making informed selection decisions, you can optimize your wireless network performance and meet the growing demands of modern connectivity.
