Document Type and Number:
WIPO Patent Application WO/2021/166315
Kind Code:
A1
Abstract:
According to the present invention, RFIC modules (101A, 101B) for an RFID tag each include: an RFIC (2); an antenna-connecting first electrode (11); an antenna-connecting second electrode (12); an RFIC-connecting first electrode (31); an RFIC connecting-second electrode (32); an impedance matching circuit that matches the impedance between the RFIC (2) and an antenna; and a rectangular substrate (1). A first coil (LA) and a second coil (LB) of the impedance matching circuit are juxtaposed on the substrate (10), a straight line (SL) passing through the center of gravity of a coil opening of the first coil (LA) and the center of gravity of a coil opening of the second coil (LB) is inclined with respect to one side of the substrate (1), and the direction of the inclination on the first RFIC module (101A) differs from that on the second RFIC module (101B).
