Abstract
The invention concerns an antenna for use as transmission/reception beacon (2), in a radiofrequency identifying en system, having a general upturned U configuration, located in a vertical plane, above the ground transversely to a passage (9), the antenna thus forming an unclosed loop. Said antenna can consist of a single wire (8), with horizontal median portion (8a), and vertical end portions (8b, 8c). The invention is applicable to a system for detecting, over a large width (L), the passage of people, animals or objects bearing electronic tags (7).
