Title: RFID TAG
Abstract:
An RFID tag 10 having: a RFIC module 20, which is equipped with a substrate 22, an RFIC chip 24 provided on the substrate 22, and a loop conductor 26 provided in the substrate 22 and connected to the RFIC chip 24; and an antenna substrate 50 on which the RFIC module 20 is mounted, and which is equipped with an antenna conductor 54 that includes radiation units 54b, 54c that radiate radio waves and a coupling unit 54a connected to the radiation units 54b, 54c and magnetically coupled with the loop conductor 26. The loop conductor 26 includes a first loop pattern 28 formed on a first main surface 22a of the substrate 22, a second loop pattern 30 formed on a second main surface 22b of the substrate, and an interlayer connection conductor 32 penetrating through the substrate 22 and serially connecting the first and second loop patterns 28 and 30.
