Decorative surface covering with embedded RF antenna and RF shield and method for making the same
First Claim
1. A system for communicating with an RFID tag, the system comprising:
- a multi-layer surface, comprising;
a layer of substrate;
a printed conductive antenna on the layer of substrate; and
at least one additional layer substrate overlying the antenna;
a transceiver configured to communicate with an RFID tag via the antenna; and
one or more computerized databases configured to provide data to or to retrieve data from the RFID tag via the transceiver.

Abstract
A technique is provided for printing an RFID antenna using conductive ink on a substrate and incorporating that substrate as a layer in a decorative surface such as a high pressure decorative laminate. In addition, a technique is provided for incorporating a conductive mesh into a surface, such as a high pressure decorative laminate, to form an RFID shield which prevents stray signals from reaching an RFID antenna. A technique is also provided for integrating both a printed antenna and conductive mesh shield into a single surface, such as a decorative surface, to allow the reading of desired RFID tags while preventing the reading of undesired RFID tags.
