要約
(EN) An RFID tag (101) comprises: a first planar conductor (10); a second planar conductor (20) partially or entirely facing the first planar conductor (10); an inductor (51), capacitor (52), and RFIC (40), constituting a portion of a closed loop of an electric current; and terminals (21, 22). Of two locations with a large electric potential difference in the closed loop of the electric current, one conducts to the first planar conductor (10), and the other conducts to the second planar conductor (20). The terminals (21, 22) conduct to the second planar conductor (20), and project outward from a region at which the first planar conductor (10) and the second planar conductor (20) are opposing.
(FR) L'invention concerne une étiquette RFID (101) qui comprend : un premier conducteur plan (10) ; un second conducteur plan (20) faisant partiellement ou entièrement face au premier conducteur plan (10) ; un inducteur (51), un condensateur (52) et un RFIC (40), constituant une partie d'une boucle fermée d'un courant électrique ; et des bornes (21, 22). Parmi deux emplacements ayant une grande différence de potentiel électrique dans la boucle fermée du courant électrique, l'un conduit vers le premier conducteur plan (10), et l'autre conduit vers le second conducteur plan (20). Les bornes (21,22) conduisent vers le second conducteur plan (20), et font saillie vers l'extérieur à partir d'une région au niveau de laquelle le premier conducteur plan (10) et le second conducteur plan (20) sont opposés.
(JA) RFIDタグ(101)は、第1平面導体(10)と、第1平面導体(10)に一部又は全部が対面する第2平面導体(20)と、電流の閉ループの一部を構成する、RFIC(40)、キャパシタ(52)、及びインダクタ(51)と、端子(21,22)と、を備える。電流の閉ループ内の電位差の大きな2箇所のうち、一方が第1平面導体(10)に導通し、他方が第2平面導体(20)に導通し、端子(21,22)は、第2平面導体(20)に導通し、第1平面導体(10)と第2平面導体(20)との対向領域より外方へ突出する。
