Abstract

A hand-portable telephone including a casing (1), an antenna device (7) with at least one radiating element (7a, 7b) located in said casing, and a protective device for absorbing a substantial part of the electromagnetic energy being radiated towards the user's head or some other body portion. The device comprises an electrically resistive layer (9) having a surface resistance of at least 25 OMEGA /square.
