Passive Antenna
Ericsson Antenna System contains a complete passive antenna portfolio with leading performance. Indoor and outdoor antennas with up to 24 ports for sector and omnidirectional sites, are part of the portfolio, that also contains street-integrated antennas.
Today's complex antenna systems, including management of the complex mix of multiple standards, bands, and layers on the same radio site, put great demands on the ability to create solutions with stable performance. By using our preferred antenna solutions together with our radios, we provide an excellent selection of quality antennas for any configuration to support communication interoperability and easy plug-and-play solutions.
We have control over the complete RF chain when designing and verifying our radios with antenna system products to guarantee top performance. Our radios offer fully integrated supervision and control of the antenna system. Our passive antenna portfolio offers a complete range of high-quality solutions including other partner products.
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.
