Après un aperçu assez détaillé sur la technologie RFID dans le chapitre 1, nous nous sommes focalisé sur les méthodes de conception d'antennes pour les tags RFID UHF passifs.
Avec la méthodologie et les techniques de conception de la littérature, nous utilisons ces approches pour concevoir des tags RFID passifs pour les applications dans la gamme UHF.
De plus, nous avons identifié quelques structures de type méandres pour valider nos approches de conception. Dans ce chapitre 2, nous présentons les conceptions du tag RFID pour les applications aussi bien à bande étroite (pour la régulation ETSI à 868MHz) qu’à bande large (860MHz - 960MHz). Ainsi plusieurs conceptions utilisant le AK3 de Tagsys ont été obtenues et permettent de simplifier la réalisation des tags en évitant la connexion physique entre la puce RFID et l’antenne du tag. De la simulation et des études paramétriques, nous obtenons les structures optimisées pour les applications RFID UHF à large bande (notées SO-08 et HO-01 ci-dessus). Les avantages et désavantages de chaque approche des conception sont aussi discutés dans ce chapitre. Ceci nous permettra dans la dernière phase d’optimiser nos tags en vue de les utiliser comme capteurs.
