CIMERA® Radomes for High‑Frequency SATCOM Applications

A New Era of SATCOM Connectivity

Modern SATCOM networks are rapidly evolving as LEO, MEO, and high‑capacity GEO systems push communication into higher‑frequency ranges. These new architectures deliver faster data rates, lower latency, and wider coverage, but they also increase the technical demands placed on every RF‑critical component, especially the radome.

As antennas move into Q/V‑band and E‑band, they become more sensitive to weather, surface accuracy, and dielectric stability. In this environment, the radome is no longer a simple protective shell – it becomes an essential part of the RF system, preserving gain, phase stability, and polarization performance.

CIMERA® Radomes are engineered for these challenges. The micro‑sandwich (stack-up up of different material layers, e.g. rigid skins and foam cores down to 0.1mm) design, low‑loss composite skins, and proprietary MILLIFOAM® core deliver predictable, low‑loss RF behavior, enabling reliable performance for next‑generation SATCOM systems.

Why SATCOM Moves Toward Higher Frequencies

SATCOM systems increasingly operate in Q/V‑band (35-75 GHz) and E‑band (71-86 GHz) to gain access to much larger bandwidths. These high‑frequency ranges enable multi‑gigabit data rates needed for cloud services, high‑resolution video, AI applications, and real‑time operations.

At these frequencies, even small material or surface variations can impact RF performance. Traditional Ku‑ or Ka‑band radomes are no longer sufficient millimeter wave antennas require radomes engineered with far tighter electrical and mechanical tolerances.

CIMERA® Radomes are designed specifically for this environment. Their low dielectric loss, stable phase behavior, and high‑frequency‑optimized materials ensure consistent RF transparency across wide scan angles and in challenging weather. This allows SATCOM antennas to maintain predictable, uninterrupted performance in Q/V‑ and E‑band operation.

Radomes Designed for Modern SATCOM Requirements

High‑frequency radomes must satisfy a combination of electrical, mechanical, and environmental criteria. CIMERA® Radomes address these requirements by integrating the radome into the RF chain from the earliest design stage. Rather than being added as an external shell, the CIMERA® Radome stack-up is tailored to the antenna’s geometry and scan‑angle requirements.

Key performance factors include:

Extremely low electrical loss to preserve link budget
Uniform dielectric behavior across the entire radome surface
Stable phase characteristics supporting phased‑array steering
Structural rigidity without compromising lightweight construction
Environmental robustness including UV, moisture, snow load, and thermal cycling

CIMERA^® Radomes for E‑Band Systems

E‑band SATCOM systems (71–76 GHz and 81–86 GHz) demand the highest degree of precision. Every fraction of a decibel counts. Even small deviations in layer thickness or surface flatness can affect the clarity of the signal.

CIMERA® Radomes are engineered to meet these extreme requirements.

They use:

CIMERA^® Radomes for Q/V‑Band Systems

Q/V‑band SATCOM systems enable significantly higher throughput for user terminals, supporting demanding applications such as remote enterprise connectivity, tactical communication, next‑generation mobility platforms, and residential broadband.

Phased‑array antennas operating in Q/V‑band require radomes that remain stable during wide‑angle electronic beam steering. CIMERA® Radomes are specifically optimized for this purpose.

Advantages include:

Low‑dispersion materials that prevent pattern distortion
Lightweight architecture enabling easy installation on buildings or vehicles
Stable dielectric performance under heat, cold, humidity, and mechanical vibration
Optimized transmission at steep scan angles required for LEO tracking

Multi‑Band Radome Concepts for Advanced SATCOM Systems

Next‑generation SATCOM terminals often combine several frequency bands-such as Ka‑band for fallback operation and Q/V‑band or E‑band for high‑capacity links. This requires radomes with multilayer architectures that maintain low loss across all required bands.

CIMERA^® multi‑band radomes achieve this by:

Materials for High‑Frequency Radomes: The CIMERA® Advantage

Material quality is one of the most critical factors affecting radome performance. At millimeter wave frequencies, small variations in dielectric constants or loss tangents can lead to significant attenuation or unwanted phase effects.

CIMERA® Radomes use materials that deliver:

The proprietary MILLIFOAM® foam core (www.millifoam.at) is central to this performance. Its lightweight, micro‑cellular foam structure provides a consistent dielectric profile while enabling sandwich constructions with precise thickness and stiffness. This ensures reliable RF behavior across all scan angles and environmental conditions.

Advantages for SATCOM Developers and System Integrators

A radome should simplify system design-not complicate it. CIMERA® Radomes provide engineering teams with predictable, repeatable performance that reduces the need for compensation measures.

Key benefits include:

More predictable antenna performance due to minimal pattern distortion from low‑loss, uniform dielectric materials
Higher efficiency as link budgets remain preserved at high frequencies
Greater design flexibility enabled by custom shapes and multi‑band options
Improved long‑term stability preventing drift or degradation over years of operation

CIMERA® Micro‑Radomes with Ultra‑Thin Foam Layers Down to 0.1 mm

CIMERA® Radome technology enables a new class of micro‑radomes that use ultra‑thin MILLIFOAM® core layers with thicknesses as low as 0.1 mm, allowing unprecedented precision in high‑frequency applications. These micro‑sandwich constructions allow exceptionally low dielectric loss, uniform material behavior, and predictable RF transparency while minimizing overall wall thickness for antennas where physical constraints and electrical sensitivity are extreme. At the same time CIEMRA micro-radomes maintain their mechanical stability due to a multi-layer- radome stack-up design, while enabling broad band transmission performance,

CIMERA® Radomes for Multi‑Band Ku / Ka / Q / E‑Band Operation

The CIMERA® Radome can be designed to be able to perform in different frequency bands at the same time. For example: Ku/Ka‑band as fallback and E‑band for standard operation. Through frequency‑optimized composite skins and precisely tuned MILLIFOAM® core layers, CIMERA® multi‑band designs maintain low insertion loss and stable dielectric behavior across widely separated bands. This architecture minimizes inter‑band interaction and preserves transmission from microwave through millimeter wave ranges. Thanks to this engineered stack‑up, CIMERA® Radomes deliver exceptionally reliable dual‑band and hybrid‑band performance, ensuring consistent gain and predictable RF transparency even under demanding high‑frequency conditions.
