Abstract
A device for radio communication (PH), such as for example radiophone, includes a shielding layer (RFS) which under operating conditions is between the antenna and the user. The shielding layer (RFS) reduces electromagnetic irradiation of the user. The shielding layer (RFS) may be movable in such a manner that it serves a cover of some operational device such as for example the headphone, display and keyboard of the apparatus when it is not use.
