RFID device and method of forming
First Claim
1. A radio frequency identification (RFID) device comprising:
- a substrate;
an antenna on the substrate; and
an interposer, wherein the interposer includes;
an RFID chip having contacts thereupon; and
interposer leads operatively coupled to the contacts of the chip;
wherein the interposer leads and the antenna are capacitively coupled together.

Abstract
A radio frequency identification (RIFD) inlay includes an electrical connection between a chip and an antenna. The electrical connection includes conductive interposer leads and a capacitive connection. The capacitive connection may involve putting the antenna and the interposer leads into close proximity, with dielectric pads therebetween, to allow capacitive coupling between the antenna and the interposer leads. The dielectric pads may include a non-conductive adhesive and a high dielectric material, such as a titanium oxide. The connections provide a convenient, fast, and effective way to operatively couple antennas and interposers.
