Abstract: A radio-frequency identification device for identifying a tubular element is provided that includes a radio-frequency identification chip connected to at least one antenna having two conductive strands and a flexible envelope enveloping the radio-frequency identification chip and strands. The envelope is a silicone material and includes a central portion overmolding the radio-frequency identification chip, and two strips extend on either side of the central portion and each strip overmolds at least one strand. Each of the two strips has a free end with a pierced boss capable of cooperating with a hose clamp. The two strips are thermoformed in a twisted configuration around a common twisting axis.

Abstract: The invention relates to electronic radiofrequency identification in the ultra-high frequency (UHF) range for marking an article (4) that is to be identified in a constraining environment. For this purpose, an electronic device (2) comprises: a dielectric substrate (12) having a peripheral edge face (13) and a ground face (15); an electronic chip (16); and a curved and short-circuited antenna (9) (PIFA) that presents a radiating area defined by at least two dipoles (19, 20). The antenna (9) on a transmission surface (14) of the substrate (12) is connected by a short-circuiting element (17) presenting a short-circuiting area presenting an area in projection on the edge face (13) that is of the order of 3% to 5% of the radiating area of the curved antenna (PIFA).
