Abstract (en)
[origin: EP2736118A1] The system has electrically conductive filiform elements (8a, 8b) forming a loop portion, where the filiform elements have different length with respect to one another. The length of one of the filiform elements is more than 50 % longer than length of the other filiform element. A fastening base (10) fastens the filiform elements. The fastening base includes an electrically conductive part in which ends of each filiform element are fastened. An antenna tuning unit (12) is electrically connected to the electrically conductive part to supply the elements with same radiofrequency signal.
