Abstract:
The present invention relates to an electronic unit (1) comprising a circuit board, PCB, (2) arranged to be mounted in a main housing (6, 7). The main housing comprises a first housing part (6) and a second housing part (7), where the first housing part (6) at least partly is electrically conducting. The PCB (2) comprises a first outer layer (3), a second outer layer (4), and a ground plane (5), where the first outer layer (3) mainly faces the first housing part (6) and the second outer layer (4) mainly faces the second housing part (7) when mounted. Furthermore, when mounted, the ground plane (5) is arranged to make electrical contact with the first housing part (6) such that a first chamber (29), facing the first outer layer (3), and a second chamber (30), facing the second outer layer (4), are formed. Said chambers (29, 30) are separated by means of the ground plane (5), such that an electromagnetic shielding is created between the chambers (29, 30).
