Expertly Designed to Perfectly Fit Your Antenna
CIMERA® radomes are precision-engineered to your application. Each unit matches exact specifications, acting as a functional component that improves antenna performance and extends service life.
The Science of Radome Engineering
Radome engineering balances opposing needs: low electromagnetic loss vs. mechanical strength; low weight vs. durability; tight fit vs. manufacturability. We use advanced methods to achieve a seamless fit that protects the antenna and preserves RF performance. Every radome supports signal propagation, structural integrity, and environmental protection.
Transmission Loss Simulation
Radome Transmission Loss Simulation Tool
Demonstrating the benefits of our approach in a clear and visual way.
Electromagnetic Compatibility
A radome must pass electromagnetic waves with minimal attenuation and distortion. We select materials with the right dielectric constant (εr) and loss tangent (tanδ) for the operating frequency band. Simulations verify transmission, reflection (S-parameters), and overall insertion loss.
Material Science
We work with fiberglass-reinforced composites and engineered thermoplastics. Selection criteria include dielectric properties (εr, tanδ), strength-to-weight ratio, impact resistance, and resistance to UV, moisture, and temperature extremes.
Composite notes: fiber orientation (±45°, 0/90°) and resin content affect stiffness and RF behavior. Thermoplastic notes: PC vs. ABS trade-offs in impact strength, molding accuracy, and dielectric performance.
Material Database
Our material database contains measured dielectric properties, mechanical strength, environmental resistance, process compatibility, and cost data. Engineers search by εr, tanδ, thickness, process (prepreg, autoclave, thermoforming), and availability.
Benefit: minimize attenuation while meeting cost and strength targets. Continuous updates add new test results and supplier grades.
Signal Propagation Analysis
We simulate wave travel through the radome to optimize geometry and wall composition. Our proprietary tool applies a plane-wave approach and predicts transmission loss and reflection vs. frequency and thickness—even without the customer’s radiation pattern.
Deliverables include plots, tables, and recommended thickness windows. We also flag resonances and suggest mitigation (core density change or skin thickness tweak).
Finite Element Analysis (FEA)
Mechanical behavior is validated with FEA. We study stress distribution, deformation, and potential failure points under wind, shock, and vibration. Ribbing, thickness, and material choices are tuned for stability.
Interfaces: fastener zones, door cut-outs, and rings are reinforced to avoid stress concentrations that cause cracks or misalignment.
Environmental Testing
Each radome is tested for high/low temperature, humidity, salt spray, flammability, and UV exposure; plus impact, and vibration. Tests confirm real-world durability and consistent performance across climates.
Requirements, Customization and Precision
A requirements management tool captures, tracks, and validates specifications from kick-off to acceptance. Measurements, controlled manufacturing, and quality checks ensure a perfect fit and repeatable results. Custom options include geometry, mounting interfaces, coatings, and markings.
Innovation and Research
We explore new materials, stack-ups, and processes. Ongoing research keeps CIMERA® ready for evolving antenna systems and emerging frequency bands.
Conclusion
CIMERA® blends electromagnetics, material science, simulation, and environmental validation to deliver radomes that protect your antenna and preserve RF performance.
