<p>The tag comprises essentially a patch antenna folded around a dielectric support whereby the patch antenna is formed essentially by an elongated continuous conductive band which is folded in order to define at least a top elongated part (2), a back part (4) and a bottom part (5), the top part comprises two elongated slots (6,7) which are positioned side by side and parallel to the length of said top part, said slots defining a middle zone of the conductive band between them, said middle zone comprising a first part (8) and a second part (8') of different lengths, which are separated from each other by a non conductive gap, and a RFID chip is connected over the said gap to each of said first and second parts (8,8').</p> |
