Reflection｜Glossary
This section is part of the Electrical Glossary for RF measurement and design.
What Is Reflection?
Reflection is the phenomenon where a portion of a signal is returned back toward the source due to impedance mismatch in a transmission line.
It occurs when the impedance of connected components is not properly matched.
Reflection is commonly evaluated using parameters such as return loss or reflection coefficient.
Excessive reflection can degrade signal quality and reduce system efficiency.
Reflection in RF and Coaxial Systems
In RF and coaxial systems, reflection is a critical factor affecting signal integrity.
Reflected signals can cause interference, standing waves, and increased signal loss.
Proper impedance matching is essential to minimize reflection.
Measurement of reflection using S11 helps evaluate and optimize RF system performance.
