Passive Antenna
Mobile networks are evolving rapidly as operators prepare for advanced 5G services, growing uplink traffic, increasing capacity demands and stricter sustainability targets. Passive antennas remain one of the most critical infrastructure investments because their RF characteristics directly influence coverage, signal quality, spectrum efficiency, network capacity and long-term total cost of ownership.
Ericsson’s complete passive antenna portfolio supports indoor and outdoor deployments, including sector, omnidirectional and street-integrated solutions. Multi-band and multi-port configurations – with selected antennas offering up to 24 ports – help operators manage multiple standards, frequency bands and network layers within a limited site footprint.
Engineered as part of Ericsson Radio System, Ericsson antennas are designed and verified together with radios and antenna system components across the complete RF chain. High antenna and beam efficiency, stable radiation patterns and low passive intermodulation help convert radio power into useful coverage and capacity while protecting uplink performance and signal quality.
Integrated capabilities such as remote electrical tilt, Smart Bias-T and antenna monitoring support easier commissioning, remote optimization and proactive maintenance. This combination of RF performance, deployment flexibility and system-level integration helps operators simplify network evolution and achieve reliable performance across urban, rural, indoor and space-constrained sites.
Performance impact
Deliver unmatched signal quality, higher network capacity, and more efficient spectral utilization with superior antenna and beam efficiency and industry-leading PIM performance.
TCO efficiency
Save deployment costs with optimized windload, lightweight, slim designs and smart installation features. Lower energy bill with reduced radio power consumption enabled by superior antenna efficiency.
Sustainable Innovation
Achieve up to 49% lower CO2 emissions with recyclable materials, energy-efficient designs, and antennas built to support your net-zero goals.
Compact Trio Net design
The new antennas with compact trio net design maximize network impact by tightly integrating three dimensions: antenna design, radiation pattern and overall system behavior. This coherent architecture delivers higher beam and antenna efficiency, stable 3D patterns and minimized pattern squint across bands, ensuring that more RF energy is converted into useful coverage, capacity and uplink performance.
Network simulations and test campaigns indicate clear, quantifiable gains such as up to +36% higher peak data rates in low+mid band CA scenarios, around +7% higher average throughput at the cell edge, uplink throughput improvements up to +30% in uplink‑limited cases and an overall SINR uplift of about +3.5 dB. These results stem from better FDD mid‑band utilization, improved multi‑layer carrier aggregation and more effective use of higher modulation and MIMO schemes.
Each design choice is evaluated through digital twins, network simulation and scenario‑based testing to maximize overall network impact. Changes in signal distribution, dipole positioning and pattern alignment directly improve antenna and beam efficiency, which in turn boosts performance, supports spectrum densification and reduces total cost of ownership.
Key benefits
-
Performance: High network performance with stronger uplink, enabled by antenna and beam efficiency around 85% versus typical ~70% reference values, more consistent multi‑band patterns and robust CA behavior that lifts both peak and cell‑edge throughput.
-
Total Cost of Ownership: Lower TCO and smarter sites through higher spectrum efficiency and interleaved configurations that can reduce required towers and tower footprint, lower site complexity and support safe, straightforward deployment.
-
Sustainability: Sustainability in every detail, supported by superior energy efficiency (more useful bits per joule) and reduced over‑provisioning, helping lower both operational energy consumption and the overall environmental footprint per carried traffic.
