An electronic unit (1) having a circuit board, PCB, (2) arranged to be mounted in a main housing (6, 7 and having a first housing part (6) and a second housing part (7), where the first housing part (6) is at least partly electrically conducting. The PCB (2) having a first outer layer (3), a second outer layer (4), and a ground plane (5). The first outer layer (3) faces the first housing part (6) and the second outer layer (4) faces the second housing part (7) The ground plane (5) is in electrical contact with the first housing part (6) forming a first chamber (29), facing the first outer layer (3), and a second chamber (30), facing the second outer layer (4). The chambers (29, 30) are separated by the ground plane (5), providing electromagnetic shielding between the chambers (29, 30). |
