Antennas for radio frequency identification tags in the form of a logo, brand name, trademark, or the like
First Claim
1. An RFID tag, comprising:
- a substrate;
an antenna formed on said substrate and including first and second conductive traces; and
an integrated circuit that is connected across said first and second conductive traces, wherein said conductive traces of said antenna are integrated with artwork printed on said substrate, wherein at least one of a size, location, and/or gaps between said conductive traces are tuned based on at least one of an impedance and a radiation pattern of said antenna.

Abstract
An RFID antenna or tag is designed to be integrated with artwork such as a logo, brand name, trademark, graphic element, and/or letters. The RFID tag comprises a substrate, which may include or be integrated with a product package. An antenna is formed on the substrate. The antenna includes first and second conductive traces that are integrated with artwork. An integrated circuit is connected across the first and second conductive traces. The conductive traces are integrated with the artwork that is printed on or otherwise integrated with the substrate. At least one of a size, location, and/or gaps between said conductive traces are tuned based on at least on of impedance and radiation pattern thereof.
