A mobile communication device (1, 10) comprises shielding components that provide electromagnetic shielding or attenuation between a first area (A) and a second area (B, B1, B2) within and/or external of the communication device (1, 10). In said first area (A) an antenna (4) and at least one ferrite (6) are arranged, which ferrite (6) is provided to interact with said antenna (4) and to guide a magnetic flux between said first area (A) and said second area (B, B1, B2).
