The invention consists in skilfully incorporating a cover-like shield which is designed to open or unfold in front of the portable telephone antenna, or to partially cover this last either as a case made of bipartite meterial or as a semi-cylindrical cover; the said cover is made of suitable material which is unpenetrable by telephony radiation; with regard to this radiation, a "sector of shadow" is formed behind said shield to cover the user's head. |
