What is printed circuit transmission line called?
- A Dielectric imprinting
- B Ground plane
- C Microstripline
- D Dielectric substrate
Correct answer: C — Microstripline. From the official ISED question bank, verified word for word.
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.
