Abstract Shielding effectiveness (SE) is a critical metric for evaluating the performance of micro-coaxial cables in high-frequency and high-interference environments.
Introduction Micro-coaxial cables are widely used in 5G communications, medical devices, and aerospace systems where electromagnetic interference (EMI) can severely degrade signal integrity. Shielding structures play a pivotal role in isolating the inner conductor from external noise and preventing signal leakage. This article compares three common shielding configurations—single, double, and triple layers—to determine their effectiveness across frequency ranges and operational scenarios.
Shielding Mechanisms and Structures 2.1 Single-Layer Shielding Structure: A single metallic layer (braided copper, spiral wrap, or foil). Mechanism: Provides basic reflection and absorption of EMI. Common Types: Braided Shield (85–95% coverage): Flexible but limited high-frequency performance. Foil Shield (100% coverage): Rigid but effective for higher frequencies. 2.2 Double-Layer Shielding Structure: Combines two layers (e.g., foil + braid, or dual braids). Mechanism: First Layer: Foil blocks high-frequency noise via reflection. Second Layer: Braid absorbs low-frequency magnetic fields. Synergy: Reduces gaps in coverage and compensates for individual layer weaknesses. 2.3 Triple-Layer Shielding Structure: Adds a third layer (e.g., foil + braid + spiral shield). Mechanism: First Layer: Foil reflects EMI. Second Layer: Braid dissipates residual energy. Third Layer: Additional spiral wrap enhances mechanical stability and SE. Applications: Extreme EMI environments (e.g., military radar, MRI machines).
Quantitative Comparison of Shielding Effectiveness 3.1 Test Methodology Frequency Range: 100 MHz to 40 GHz. Standards: IEC 62153-4-3 (Triaxial Method), MIL-STD-461.
3.2 Performance Data Shielding Type Shielding Effectiveness (dB) Transfer Impedance (mΩ/m) Optimal Frequency Range Single-Layer (Foil) 40–60 dB 5–20 mΩ/m 1–10 GHz Single-Layer (Braid) 30–50 dB 10–50 mΩ/m DC–2 GHz Double-Layer 60–80 dB 1–5 mΩ/m 100 MHz–20 GHz Triple-Layer 80–100 dB 0.5–2 mΩ/m 100 MHz–40 GHz 3.3 Frequency-Dependent Behavior Single-Layer: Braid: SE declines above 2 GHz due to “aperture effect” from weave gaps. Foil: Performs better at higher frequencies but is vulnerable to cracks. Double/Triple-Layer: Maintain stable SE across wider ranges due to complementary layers.
Trade-offs in Design and Application 4.1 Flexibility and Weight Single-Layer: Lightweight and highly flexible (ideal for wearable devices). Triple-Layer: Stiffer and heavier due to multiple layers (suited for fixed installations). 4.2 Cost and Complexity Single-Layer: Low cost, simple manufacturing. Triple-Layer: 2–3x higher cost, requires precision lamination and testing. 4.3 Durability Foil Layers: Prone to damage during bending. Braid Layers: Withstand repeated flexing but degrade over time.
Future Trends Nanocomposite Shields: Carbon nanotube-infused layers for ultra-high SE with minimal weight. Adaptive Shielding: Smart materials that adjust SE dynamically based on EMI levels.
