3 Electromagnetic emissions mechanisms from PCBs

Subsections

• 3.1 Conducted emission - Radiated emission
• 3.2 Direct radiation from PCB sources
  • 3.2.1 Direct radiation from trace and IC package loops on the PCB
  • 3.2.2 Direct radiation from plane edges on the PCB
  • 3.2.3 Direct radiation from a PCB which is parallel to a metallic cover plane at an electrically short distance
  
  
• 3.3 Emissions through galvanic coupling, electric and magnetic near field coupling to cables, long nets, and mechanical structures, interpreted as antennas
