New Technical Guide: A Practical Approach to Antennas for EMC Compliance
AMETEK CTS has released a new technical note,
A Practical Guide to Antennas for EMC Compliance, designed to support engineers and compliance professionals in selecting and using antennas more effectively during EMC testing.
This in-depth guide consolidates key RF theory and practical test setup considerations into a single, accessible resource. Covering core topics such as antenna gain, directivity, VSWR, effective aperture, polarization, and the Friis transmission equation, it offers both foundational knowledge and application-specific insights.
Engineers working to IEC 61000-4-3 and CISPR 11 standards will find particular value in the included real-world examples. These highlight how AMETEK CTS antennas—such as the CBL 6111D and HLA 6121—perform in typical emission and immunity test environments.
Topics include:
•
Key electromagnetic wave principles
•
How antenna characteristics influence measurement accuracy
•
Antenna factor and field strength conversion
•
Practical calculations for test setup power and distance
•
Application-specific examples for both radiated immunity and emission testing
Whether you're configuring a new test setup or troubleshooting field strength measurements, this guide is a reliable reference for enhancing test confidence and compliance accuracy.
