ABSTRACT:
An RFID device, such as an RFID tag or label, includes a combined reactive coupler electrically coupling a transponder chip to an antenna. The combined reactive coupler includes a magnetic coupler and a capacitive coupler. The magnetic coupler and the reactive coupler may have respective coupling elements on both the interposer and on an antenna substrate.
