An RFID device (10), such as an RFID tag or label, includes a combined reactive coupler (11) electrically coupling a transponder chip (26) to an antenna (20). The combined reactive coupler includes a magnetic coupler (12) and a capacitive coupler (13). The magnetic coupler and the capacitive coupler may have respective coupling elements (22, 28 and 24a, 24b, 29a, 29b) on both an interposer (16) and on an antenna portion (14). |
