Abstract
In the field of electronic apparatuses that can be held in the hand and that comprise a miniaturized radio antenna, an apparatus comprises a casing of generally parallelepipidal form with a main face and a first small side. The antenna extends partly along the main face and partly over the first side. It comprises a conductive structure divided up so as to form a meandering inductive conductive line linked to a main conductive surface which extends over most of the first side and which is folded at the ends of this first side onto a second and a third side adjacent to the main face to form two folded lateral wings, at least one respective slot being provided to separate each wing from the main conductive surface and thus narrow and lengthen the paths of the electric currents going to the folded lateral wings.
