ABSTRACT:
The antenna and the electronic control circuit of the transponder are contained in a totally hermetical metallic enclosure. The antenna of the reader is protected from the environment by a metallic front plate that is integral with the enclosure containing the electronic control circuit. In a preferred embodiment, the enclosure is hermetically tight. These embodiments fulfill the longstanding need to obtain completely tight elements that are resistant to industrial aggressions.
