Study Reveals Superior EMC Performance of 360° Shielded Cable Termination vs. Pigtail
A new study published in the IEEE Xplore Digital Library in July 2026 compares the electromagnetic compatibility performance of two typical shielded cable termination methods: Pigtail termination and 360° fully shielded termination .
Research Methodology:
Adopted a collaborative research approach of theory-simulation-verification
Used electromagnetic simulation software FEKO
Constructed simulation models of three typical cable lengths: 400 mm, 200 mm, and 20 mm
Precisely replicated shielding layer structure, termination method, and grounding path
Key Findings:
Regardless of cable length, 360° termination is more effective in suppressing electromagnetic radiation than Pigtail termination
360° termination significantly improves EMC performance
The study provides rapid analysis and prediction of EMC performance differences in cable terminations
Practical Implications:
The research offers theoretical and data-based support for engineering design of shielded cable terminations, particularly important in automotive and aerospace applications where EMI control is critical .
