Comment appelle-t-on une ligne de transmission fabriquée sous forme de circuit imprimé?
- APlan de sol ("ground plane")
- BLigne microruban ("microstrip line")
- CSubstrat diélectrique

Correct answer: B — Ligne microruban ("microstrip line"). Question tirée de la banque officielle d'ISDE.
Why
A microstripline is a specific type of printed circuit transmission line made by placing a thin strip of copper on top of a flat insulating board, which acts as the ground plane underneath. The full explanation — and one for every question — is in Pro.
