Title
(EN) IC TAG SYSTEM
(FR) SYSTEME D'ETIQUETTE A CIRCUIT INTEGRE
(JA) ICタグシステム
Abstract
(EN) In an IC tag system provided with, for instance, an IC tag (201a) which operates in a band of 2.45GHz, and a reader/writer antenna, a length (L) of an antenna (203a) of the IC tag (201a), which is normally approximately 60mm, is shortened to approximately 5mm. A small reader/writer antenna (type [3]) having a size of, for instance, approximately a 1.2mm square, is used, corresponding to the shortened antenna length. By combining such small IC tag (201a) with a small reader/writer antenna, systems such as a system for controlling a small component by mounting the IC tag (201a) on the component, and a high resolution location detecting system for detecting the IC tag (201a) by the small reader/writer antenna by mounting the IC tag (201a) at high density can be provided.
(FR) Dans un système d'étiquette à circuit intégré muni, par exemple, d'une étiquette à circuit intégré (201a) qui fonctionne dans une bande de 2,45 GHz et d'une antenne de lecture/écriture, la longueur (L) de l'antenne (203a) de l'étiquette à circuit imprimé (201a), qui est normalement d'approximativement 60 mm, est raccourcie à approximativement 5 mm. Une petite antenne de lecture/écriture (de type [3]) présentant la taille, par exemple, d'un carré d'approximativement 1,2 mm, est utilisée, ce qui correspond à la longueur de l'antenne raccourcie. En combinant une petite étiquette à circuit intégré (201a) de ce type avec une petite antenne de lecture/écriture, on peut fournir des systèmes tels qu'un système destiné à commander un petit composant en montant l'étiquette à circuit intégré (201a) sur le composant, ainsi qu'un système de détection d'emplacement à résolution élevée destiné à détecter l'étiquette à circuit intégré (201a) grâce à la petite antenne de lecture/écriture en montant l'étiquette à circuit intégré (201a) avec une haute densité.
(JA)  例えば、2.45GHz帯で動作するICタグ201aとリーダライタ用アンテナを備えたICタグシステムにおいて、通常60mm程度となるICタグ201aのアンテナ203aの長さLを5mm程度まで小さくし、これに応じて、例えば1.2mm角程度の大きさを備えた小型のリーダライタ用アンテナ(種別[3])を用いる。そして、このような小型のICタグ201aと小型のリーダライタ用アンテナとを組み合わせることで、例えば、小型の部品にICタグ201aを実装して部品を管理するシステムや、ICタグ201aを高密度に実装して、それを小型のリーダライタ用アンテナで検出するような高分解能の位置検出システムが実現可能となる。
